The Eponym Dictionary of Southern African Plants
Plant Names G-K


Note: Names for which I have no derivations or about which I have further questions are being put on a separate page here and will be investigated further at a later date. I have included names which are no longer current because the individuals which these names commemorate nevertheless contributed to Southern African flora and deserve to be recognized and remembered. Also included here are the generic names of invasive species. Many of my entries have been added to and fleshed out by additional information from Hugh Clarke from the work which we hope at some point to have published, and I thank him greatly for the work he has done.


Gagea
: for Sir Thomas Gage (1781-1820), English botanist and plant collector in Ireland and the Iberian peninsula, 7th Baronet of Hengrave Hall in Suffolk, Fellow of the Linnean Society, and a contributor to English Botany by James Sowerby and J.E. Smith. The genus Gagea in the Liliaceae was published in 1806 by British botanist Richard Anthony Salisbury.

Gaillardia
: for Antoine René Gaillard de Charentonneau, an 18th century French magistrate, patron of botany, naturalist, amateur botanist, and member of the Académie des Sciences. The estate of Charentonneau was apparently acquired in 1671 by a René Gaillard de Monmire (died 1709) who may have owned a nearby castle, and it was subsequently held by that family, first by his brother Pierre (died 1717), then by Pierre's son René (died 1744), and finally by his son Antoine René. David Hollombe adds this: "Signing a document as a witness in November 1763, he gave his age as 43," which would make his birth year around 1720. Antoine René was an officer of the courts from 1740 to 1771 and from 1774 to 1779. His date of death is unclear. He also received seeds of plants from the French colonies which he both cultivated himself and shared with other botanists. The genus Gaillardia in the Asteraceae was published in 1788 by French zoologist, botanist and botanical illustrator Auguste Denis Fougeroux de Bondaroy. (CRC World Dictionary of Plant Names; David Hollombe, pers. comm.)

Gaillonia: for François Benjamin Gaillon (1782-1839), French algologist specializing in marine plants. He was a correspondent of several academic societies such as the Linnean Society and the author of Essai sur l'étude des thalassiophytes, ou plantes marines. Also "[h]e contributed to the Flore générale de France ou Iconographie, description et histoire de toutes les plantes (Flora of France and General Iconography, description and History of all the plants) (1828-1829) undertaken by Jean-Deslongchamps Loiseleur, with Christiaan Hendrik Persoon, Jean-Baptiste Alphonse Dechaffour de Boisduval and Louis Alphonse de Brébisson." He also contributed to Dictionaaire des Sciences naturelles by Cuvier, Lamarck and Jussieu. The genus Gaillonia in the Rubiaceae was published by Swiss botanist Augustin Pyramus de Candolle in 1830. (CRC World Dictionary of Plant Names; Hugh Clarke)

gairdnerae: for Miss A.E. Gairdner (fl. 1910-1912), a plant collector in Zimbabwe. The taxon that has this specific epithet in southern Africa and was collected by Miss Gairdner is Indigofera gairdnerae. (JSTOR)

Galenia: for the Greco-Roman Claudius Galen (c.130-200 AD), one of the most eminent physicians of his age and a prolific writer with around 600 treatises on medicine, anatomy, physiology, logic and philosophy, about a third of which remain. Wikipedia states that "Galen continued to exert an important influence over the theory and practice of medicine until the mid seventeenth century in the Byzantine and Arabic worlds and Europe." Eventually certain limitations of Galen's work were demonstrated to have arisen as a result of the fact that he based his conclusions on monkey anatomy (human dissection was not permitted) but nevertheless in the history of medicine he is clearly one of the most significant scholars of the ancient world. The genus Galenia in the Aizoaceae was published in 1753 by Swedish botanist Carl Linnaeus. (CRC World Dictionary of Plant Names; Wikipedia)

Galinsoga: for Don Ignacio Mariano Martinez de Galinsoga (1766-1797), Spanish botanist, physician in Madrid, founder and Superintendent of the Real Jardín Botánico de Madrid and founder of the Spanish Real Academia Nacional de Medicina, and at one time physician to the Queen Consort of Spain Maria Luisa of Parma, wife of King Charles IV. He was the author of Demostración mecánica de las enfermedades que produce el uso de las cotillas published in 1784 which was about "the health hazards inherent in the wearing of corsets." The Spanish botanists Hipólito Ruiz López and José Antonio Pavon published the genus Galinsoga in the Asteraceae in 1794. (CRC World Dictionary of Plant Names; Flora of Australia Online; Wikipedia)

Galpinia/galpinii: for Ernest Edward Galpin (1858-1941), a South African botanist and banker. He left some 16,000 herbarium specimen sheets to the National Herbarium in Pretoria which formed the nucleus of its collection, and he was called "the Prince of Collectors" by none other than General Jan Smuts. Galpin discovered half a dozen genera and many hundreds of new species. Numerous species are named after him and his farm called 'Mosdene' is commemorated in the genus Mosdenia. He sent many specimens to botanists such as Harry Bolus, John Medley Wood and Peter MacOwan. His wife was the botanical artist Marie Elizabeth de Jongh who was an outstanding mountaineer who loved the veld and had a keen eye for new species. A life member of the Linnean Society, Vol. 13 of Flowering Plants of South Africa was dedicated to him. He introduced many indigenous plants to the horticultural world including such popular garden plants as Bauhinia galpinii, Cyrthanthus galpinii, Kleinia galpiniiKniphofia galpinii, Streptocarpus galpinii and Watsonia galpinii. The genus Galpinia in the Lythraceae was named by British botanist Nicholas Edward Brown in 1894. (CRC World Dictionary of Plant Names; Wikipedia; Gerbera.org)

galpiniae: for Marie Elizabeth Galpin (1859-1933) (née de Jongh), wife of Ernest Edward Galpin whom he married in 1892. She had painted some of his new plant discoveries and shared many of his collecting expeditions with him. She is commemorated with Lampranthus galpiniae and Wahlenbergia galpiniae. (JSTOR)

Galtonia: for Sir Francis Galton (1822-1911), British anthropologist, traveller and explorer, geographer, meteorologist, inventor, psychometrician and statistician, cousin of Charles Darwin, founder of the science of eugenics and pioneer of fingerprinting. He was an incredibly productive man who was involved in almost too many things to even list, such as psychology, meteorology, genetics and heredity, statistics, and biology. He coined the phrase "nature versus nurture," devised the first weather map, founded the biometric approach to genetics, and was the author of Narrative of an Explorer in Tropical South Africa, The Art of Travel, Hereditary Genius and others. He travelled widely in Central Africa and explored unknown areas of South-West Africa (now Namibia) in 1850. He published over 340 papers and books, received many honors, such as Fellow of the Royal Society, and was knighted in 1909. The genus Galtonia in the Hyacinthaceae was published in 1880 by French botanist and agronomist Joseph Decaisne. (CRC World Dictionary of Plant Names; Wikipedia)

Gammiella: for George Alexander Gammie (1864-1935), Indian phytologist. Hugh Clarke provides the following: "...author and authority especially of Indian flora and moss collector in Sikkim. He was employed by the Cinchona Department of Bengal as Deputy Superintendent of one of the cinchona plantations. Later, he became a lecturer in botany at the College of Science at Poona. A commercial problem for the government was how to extract from quinine the rapidly increasing stock of crown and yellow bark. The government quinologist C.R. Wood suggested a method which Gammie put into practice. This method was so successful that all the government hospitals and dispensaries in India had all the quinine they needed (some 5000 to 6000 pounds annually)." The genus Gammiella in the Sematophyllaceae was published in 1908 by Finnish botanist Viktor Ferdinand Brotherus.

gandogeri: for Abbé Michel Gandoger (1850-1926), French botanist and mycologist who travelled extensively in Crete, Spain, Portugal and Algeria, assembled a herbarium of 800,000 specimens now kept at the Faculty of Lyon, a notorious 'splitter' known for having published thousands of species that are no longer accepted, author of Flora europaea in 27 volumes, commemorated with Leucadendron gandogeri. (David Hollombe, pers. comm.)

garciae: Erica garciae, named for the type locality near Garcia's Pass, Riversdale District, and not for a person.

Garcinia/garcinii: for Laurent Garcin (1683-1752), French-born Dutch army physician, botanist and naturalist of the Dutch East India Company and plant collector for Herman Boerhaave, and for García de Orta (1501/1502-1568/1570), Portuguese physician and naturalist, pioneer of tropical medicine. The genus Garcinia in the Clusiaceae was published by Swedish botanist Carl Linneaus in 1753. Garcin was also commemorated with Polygala garcinii. (CRC World Dictionary of Plant Names)

garckeana: for Christian August Friedrich Garcke (1819-1904), German botanist and plant collector, appointed curator in 1865 of the Königlichen Herbarium (later Königlich botanisches Museum) in Berlin, associate professor of botany at Berlin specializing in pharmacognosy (the study of medicines derived from natural sources), author of Flora von Nord- und Mitteldeutschland (Flora of North and Central Germany) and the two-volume Flora von Halle, editor of the journal Linnaea, commemorated with Azanza garckeana published in 1954 and with Indigofera garckeana which has now been synonymized to I. homblei. (Flora of Zimbabwe; Wikipedia; Sappi What's in a Name: The Meanings of the Botanical Names of Trees)

Gardenia: for Alexander Garden (1730-1791), Scottish-born botanist and physician, correspondent of Linnaeus to whom he sent many plant samples, and Fellow of the Royal Society, lived for over 30 years in the United States where he practiced medicine, inoculating over 2000 people during a smallpox epidemic in Charleston, and supported England in the American Revolutionary War resulting in the confiscation of his property. Ironically, the plant name that is most associated with him had nothing to do with his work but was assigned by Linnaeus to a South African species. In addition to plants, he was intensely interested in and collected birds, fish, reptiles, amphibians and insects. The genus Gardenia in the Rubiaceae was published in 1761 by British linen merchant and naturalist John Ellis. (CRC World Dictionary of Plant Names; Wikipedia)

gardenii: for Maj. Robert Jones Garden (c.1821-1870), soldier-naturalist who was stationed in KwaZulu-Natal with the 45th (The Nottinghamshire) Regiment of Foot. In an essay by John van der Linde in the Clivia Society Newsletter (Vol 12, Number 2, 2003), it is stated that he was a "gifted and observant journal writer, a prickly personality; a talented amateur, geologist, artist and a plant collector of note." He may have been born in India but there are few records of his ancestry. He sent many plants to Kew both from South Africa and from India. He is commemorated with Clivia gardenii and Streptocarpus gardenii, both of which Garden brought when he arrived in England from South Africa. British soldier and civil servant. From JSTOR: "Robert Jones Garden enlisted in 1839 in the 45th Regiment of the British Army in India and came to South Africa in 1847 to fight in the Frontier Wars in the Eastern Cape. Promoted to Captain in 1848, he was stationed at Pietermaritzburg in Natal. He had a reputation as a quarrelsome type, which may explain why he was chosen by his commanding officer to leave camp on a number of official trips, during which, travelling by ox-wagon, he collected plants and geological specimens. His task on one of these missions, which he failed to accomplish, was to find a new pass across the Drakensberg to what is now the Free State. After retiring as a Major in 1854, he returned to England with a collection of living plants, which he presented to W.J. Hooker at Kew. Several new species were based on his collection, including Begonia natalensis Hook. and Hypoxis latifolia Hook., and three species, Clivia gardenii Hook., Streptocarpus gardenii Hook. and Albuca gardenii Hook., were named by Hooker in his honour. He also brought back a collection of fossils from Pondoland, which he had collected in 1851 and contained previously unknown species of molluscs. During his time in Natal, he kept a journal and made drawings and watercolour paintings, one of which, a drawing of Phoenix reclinata Jacq., was reproduced by C.J. Andersson in his book Lake Ngami (1856). The intention of Robert Garden seems to have been to retire in England, where he could work on and ultimately publish these writings. Instead, after two years, he left for India to take up a post in the consular service, from where he continued to send plants to W.J. Hooker until at least 1862." (Elsa Pooley; Clivia Society; Gunn & Codd; JSTOR)

gardineri: for John Stanley Gardiner (1872-1946), British zoologist and pioneering oceanographer who studied coral reefs. He was Professor of Zoology and Comparative Anatomy at the University of Cambridge from 1909-1937, a Fellow of the Royal Society, and author of Coral Reefs and Atolls (1931) and a number of other works. He is commemorated with Parinari gardineri, now synonymized to P. curatellifolia, the type specimen of which he collected in the Seychelles. (Wikipedia; David Hollombe, pers. comm.)

gardneri: for a J. Gardner, plant collector who collected Tragia gardneri in Zimbabwe in 1905. (JSTOR)

gardnerianum: for a Mr. Edward Gardner, the East India Company's Resident at Katmandu, the seat of the Nepal government. The son of Admiral Lord Gardner, he was credited with contributing greatly to the riches of the Botanic Garden at Calcutta, and through it to the gardens and herbariums of England. Hedychium gardnerianum was introduced into Britain from Calcutta. (The Botanical Register, Vol. 9; Jardim Formoso)

garnieri: for Frederic Benoit Garnier (1822-1883/84), French envoy in Madagascar (1867-1871), later consul in Shanghai, Batavia and Bangkok, his will created a foundation to fund scientific exploration in Asia and Africa. He collected Gladiolus garnieri (now G. dalenii) in Madagascar. (David Hollombe, pers. comm.)

garnotianus/garnotii: for Prosper Garnot (1794-1838), French surgeon and naturalist aboard the corvette "La Coquille" on a voyage around the world (1822-1825) during which he collected at the Cape. After an attack of dysentary, he was sent home with some of the collection, but it was lost when the vessel wrecked off the Cape of Good Hope. He is commemorated with Relhania garnotii and the former taxon Restio garnotianus, which is now R. filiformis, and also with the genus Garnotia, which does not appear in southern Africa. (Gunn & Codd; Wikipedia)

garsidei: for Sidney Garside (1889-1961), British-South African botanist and bryologist, born in Manchester, died at Cape Town, plant collector and plant name author, worked extensively at the Bolus Herbarium, member of the Linnean Society and the Royal Society of South Africa, lecturer in botany at the Royal Technical College at Salford, lecturer in plant physiology at Stellenbosch University, lecturer in botany at Bedford College, University of London, companion to H.W.R. Marloth on his collecting trips, collected about 2500 specimens mainly while travelling by bicycle, commemorated with Riccia garsidei, Cephaloziella garsidei and the former Frullania garsidei (now F. variegata). (Wikipedia; JSTOR; Gunn & Codd)

Gasparrinia: for Guglielmo Gasparrini (1804-1865), Italian botanist and mycologist, professor of plant anatomy and morphology at the University of Pavia 1857 to 1861, professor of botany at Naples and Director of the Botanical Garden of Naples 1861 to 1866. The genus Gasparrinia in the Apiaceae was published in 1839 by Italian botanist Antonio Bertoloni. (Acta Plantarum: Etymology of Names Botanical and Mycological)

gassneri: for an A. Gassner (fl. 1975-1984), plant collecter in Zambia and Malawi, who with Börge Pettersson collected Nervilia gassneri in Malawi in 1984. (JSTOR)

gaudichaudianus/gaudichaudii: for Charles Gaudichaud-Beaupré (1789-1854), French botanist who served on the circumglobal expedition of Louis de Freycinet on the l'Uranie and Physicienne from 1817-1820, and is known for his collections in Australia. In 1831 he visited Chile, Argentina and Peru, and then circled the globe again in 1836. He is the author of Flora of the Malouine Islands, Treatise on the Cycads, Voyage of the Uranus, and other works. He is commemorated with Syrrhopodon gaudichaudii, Leptotheca gaudichaudii and Restio gaudichaudianus. (Australian National Herbarium Biography; Wikipedia)

gaussenii: probably for Henri Marcel Gaussen (1891-1981), French botanist and plant name author. The taxon in southern Africa that had this specific epithet was Mesembryanthemum gaussenii, published in 1954 by French botanist Claude Leredde and now synonymized to M. cryptanthum.

gawleri: for John Bellenden Ker (originally John Gawler) (1764-1842), botanist and author on diverse topics from archaeology to nursery rhymes, an Iridaceae specialist. He changed his name to Ker Bellenden but continued to use the name Bellenden Ker until his death. His father's name was John Gawler, but his maternal grandfather was the Baron Bellenden. He was granted the license to take the name Ker Bellenden by King George III. His son followed his example and went by the name Charles Henry Bellenden Ker. He was the author of Recensio Plantarum and Iridearum Genera, and was the first editor of the magazine The Botanical Register. From 1828 on he was more involved with archeological matters and with his interest in nursery rhymes. He is commemorated with Moraea gawleri. (Dictionary of National Biography)

gayana/gayanus: for (1) Jacques Étienne Gay (1786-1864), French civil servant and botanist, commemorated with Blainvillea gayana, and with the genus Gaya, which does not appear in southern Africa. (Hugh Clarke, pers. comm.; JSTOR); (2) Claude Gay (1800-1873), French natural historian, illustrator and writer who studied in Paris under such notables as Georges Cuvier, René Louiche Desfontaines and Antoine de Jussieu, botanist in Chile 1824-1841, editor of Historia fisica y politica de Chile in 26 vols, honored with the taxa Digitaria gayana, Chloris gayana, and Andropogon gayanus. (Etymological Dictionary of Grasses)

Gazania: usually reported as honoring Theodorus Gaza (1398–1478), a great Greek classical scholar and humanist of the Renaissance, one of the leaders of the revival of learning in the 15th century, whose patrons included the Este family, Pope Nicholas V, and Cardinal Bessarion, professor of Greek at the University of Ferrara, translator of Aristotle and of the botanical works of Theophrastus, notably the Historia Plantarum, from Greek into Latin, and a man much respected by his contemporaries but even more so by succeeding generations. This may in fact be the derivation, or it may be some other derivation that is not from a personal name. The genus Gazania in the Asteraceae was published in 1791 by German botanist Joseph Gaertner who did not explain the derivation of the name. (PlantzAfrica, CRC World Dictionary of Plant Names, Wikipedia, Catholic Encyclopedia)

geardii: for a certain Mr. Geard on whose farm Gladiolus geardii was found, with no further information. The holotype was collected in the Uitenhage area in 1932 by A.H. Harcourt-Wood, according to JSTOR specimen records.

geesterani: probably for Rudolf Arnold Maas Geesteranus (1911-2003), Dutch mycologist and plant collector in South Africa, Kenya, India and the Netherlands. The taxon in southern Africa with this specific epithet is the lichen species Xanthoparmelia geesterani, published by Mason E. Hale, Jr. in 1972. (JSTOR)

Geigeria: for Dr. Philipp Lorenz Geiger (1785-1836), German chemist, pharmacist and professor of pharmacy at the University of Heidelberg. In 1835 he discovered the poisonous alkaloid coniine in hemlock (Conium). He also isolated atropine, an alkaloid found in nightshade (Atropa belladona), jimsonweed (Datura stramonium) and mandrake (Mandragora officinarum), and the related alkaloids aconatine, daturine, hyoscyamine and atropine. From 1824 to 1836 he edited the Magazin der Pharmazie. His major works were the Pharmacopoeia universalis and his Handbuch der Pharmacie. The genus Geigeria in the Asteraceae was published in 1830 by German botanist and homeopathic physician Philip Wilhelm Ludwig Griesselich. (Elsa Pooley, JSTOR; Kremers and Urdang's History of Pharmacy; David Hollombe, pers. comm.)

geldenhuysii: for Coert Johannes Geldenhuys (1946- ), South African forest officer engaged in research on management of indigenous forests. The isotype of Apodytes geldenhuysii was collected by Geldenhuys in1984 in the Vogelgat Nature Reserve. (JSTOR)

Genista: a Latin name from which the Plantagenet kings and queens of England took their name, planta genesta or plante genest, and alluding to a story that when William the Conqueror set sail for England, he plucked a plant where it was holding fast, tenaciously, to a rock and stuck it in his helmet as a symbol that he would also hold fast in his risky endeavor. The plant was the common broom flower, called planta genista in Latin. This is a good story but unfortunately William the Conqueror came well before the Plantagenets and it was actually Geoffrey V of Anjou, Duke of Normandy, called 'the Handsome,' who was nicknamed 'Plantagenet' because he carried a yellow-flowered sprig of broom on his helmet as a badge (genêt is the French name of the broom shrub), and it was his son, Henry II, who became the first Plantagenet king. Other historical explanations are that Geoffrey planted this shrub as a hunting cover or that he used the broom to scourge himself. It was not until Richard, Duke of York, father of both kings Edward IV and Richard III, that members of this family adopted the name Plantagenet, and it was then retroactively applied to the descendents of Geoffrey of Anjou as the dynastic name. The Celtic gen means 'bush.' The genus Genista in the Fabaceae was published in 1754 by Swedish botanist Carl Linnaeus. (The American Botanist by Willard Nelson Clute; A Gardener's Handbook of Plant Names by Archibald Smith; Wikipedia)

Genlisea: for Stéphanie Félicité Ducrest de Saint-Aubin, Comtesse de Genlis (1746-1830), who wrote more than 80 works on a wide range of subjects including historical novels and romances. She lived her life against the backdrop of the French Revolution and although she herself was sympathetic to it, her husband was guillotined. The genus Genlisea in the Lentibulariaceae was published in 1883 by French botanist Auguste François César Prouvençal de Saint-Hilaire. (CRC World Dictionary of Plant Names)

gentilii: for Théodore August Louis François Gentil (1874-1949), plant collector who collected a specimen of Angraecum gentilii in 1903. (Gledhill)

geoffreyi: for Geoffrey James (fl. 1931), plant collector, according to Etymological Dictionary of Succulent Plant Names. There is however a JSTOR specimen record for the holotype of Stomatium geoffreyi being collected by H.W. James in 1931 near Halesowen, South Africa, and this could be the same individual or a case of brothers. This is further suggested by the fact that Eggli and Newton list "fl. 1931" for both Geoffrey and H.W. James.

Georgeantha: for Alexander Segger George (1939- ), Australian botanist and botanical historian. Hugh Clarke provides the following: "He started his career as a laboratory assistant in 1959 at the Western Australian Herbarium and studied botany at the University of Western Australia. in 1968, he was seconded as Australian Botanical Liaison officer at the Royal Botanical Gardens, London. An authority on the genera Banksia and Dryandra, he wrote, inter alia, The Banksia Book (1984) and An Introduction to the Proteaceae of Western Australia (1985) as well as popular wild flower books on Western Australia and historical biographies. From 1981-1993 was Executive Editor for the Flora of Australia series. He also served as an Adjunct Associate Professor with the School of Biological Sciences, Murdoch University. In 2012 he was awarded the Order of Australia for 'service to conservation and the environment as a botanist, historian and author...'" The genus Georgeantha in the Ecdeiocoleaceae was published in 1998 by Australian botanists Barbara Gillian Briggs and Lawrence Alexander Sidney Johnson.

georgica: Erica georgica, named for the type locality of Montagu Pass, George District and not for a person.

geraldii: for Gerald Graham ("G.G.") Smith (1892-1976), South African engineer, amateur naturalist and student of Haworthia, associated with the East London Museum and the South Africa Museums Association, made a collection of several thousand living plants, commemorated with Haworthia geraldii. (Gunn & Codd)

Gerardia: for John Gerard (1545-1612), British physician and surgeon, one of the best known of the British herbalists, author, and remarkably successful gardener who for some 20 years supervised gardens such as the physic garden of the College of Physicians of London, and those belonging to wealthy aristocrats such as Lord Burleigh in the Strand, and the garden at Theobalds in Hertfordshire, also his own famous garden in Holborn, for which he published in 1596 a catalogue of 1033 plants and trees he cultivated there (Catalogue Arborum, Fruticum et Plantorum) and which was the first complete catalogue ever published of the contents of a single garden. He was perhaps best known as author of The herball or Generall historie of plantes (1597) including the first illustration of a potato. This work was largely not original but based on that of Rembert Dodoens and Jacob Dietrich, however he did include many personal observations, contemporary folklore and antiquarian references. It has often been stated that 1607 was the year of his death but this appears not to be the case. The genus Gerardia in the Orobanchaceae (formerly Scrophulariaceae) was published in 1846 by British botanist George Bentham. (CRC World Dictionary of Plant Names; Wikipedia; website of the University of Glasgow on Printing in England; Tropicos; "Herbals: the Vade Mecum [Manuals] of the Sixteenth and Seventeenth Centuries" by William Peacher, Library Associates, Syracuse University)

Gerbera/gerbera: for Traugott Gerber (1710-1743), a German (Silesian) medical doctor, botanist and naturalist, son of a Lutheran ptriest, and the Curator of the oldest botanical garden in Moscow called the Moscow Physic Garden. He travelled extensively in Russia, headed some expeditions to search for medicinal plants in the Volga, Don and Black Sea regions between 1739-1741, accompanied the Russian Army as a doctor to Finland, was the author of Dissertationem physicam de Plantarum transpiratione, and was a close friend of Swedish botanist Carl Linnaeus, who published the genus Gerbera in the Asteraceae in 1758. Based on his travels in 1739 and 1741, he compiled three regional floras, Flora mosquensis, Flora volgensis, and Flora tanaecensis. He lectured in anatomy at the Medical Institute and was a surgeon there. He died at the young age of 33. Some sources also include his brother, a Fr. Gerber who collected plants in the West Indies, in the commemoration. He was also commemorated with the former taxon Arnica gerbera, which is now synonymized to Gerbera linnaei. One source that I found (a Russian website) says that Gerber was a colleague of Dutch botanist Jan Frederik Gronovius. Gronovius apparently was the first one to name the genus Gerbera in 1737, but according to the International Code of Botanical Nomenclature, scientific plant names published before 1 May 1753 are not considered truly promulgated, so Linnaeus' publication is considered to be the valid one. (PlantzAfrica; Gerbera.org; JSTOR)

Gerdaria: the genus Gerdaria in the Orobanchaceae (formerly Scrophulariaceae) was published in 1845 by Czech botanist Carl Borivoj Presl, with no information as to its derivation. The only species in this genus, Gerdaria dregeana, has been synonymized to Sopubia simplex. It suddenly occurred to me as I wrote these notes that Gerdaria might be an anagram of Gerardia, and when I looked this up, I found that there is a taxon Gerardia dregeana which has also been synonymized to Sopubia simplex. So that is the answer.

gerhardii: for Gerhard Petrus Kotze ("Kallie") Kirsten (1932-2000), South African amateur botanist and plant collector, journalist and sports reporter for Die Burger, archivist at financial services company SANLAM Limited, co-author of Ericas of South Africa with Dolf Schumann, collector of much Erica material, commemorated with Erica gerhardii. (Ted Oliver, pers. comm.)

gerlindae: for Gerlinde Meyer, wife of plant name author Paul Gerhard Meyer (1934- ), commemorated with the former taxon Blepharis gerlindae, now synonymized to B. obmitrata.

Germanea: for Jean-Joseph de Saint-Germain (1719-1791), "...French bronze caster and clock maker, artist, amateur botanist and distinguished cultivator of plants who grew a number of very rare plants in his garden. M. de Lamarck named this genus [in the Lamiaceae] after Germain in 1788, shortly after the plant had bloomed for a first time. Later its name was changed to Plectranthus. Saint-Germain published Manuel des végétaux ou Catalogue latin et françois de toutes les plantes, orbres et arbrisseaux connus sur le globe de la terre jusqu'à ce jour (1784). This book was arranged according to the Linnaean system by classes, orders, genera, and species naming places where [some of them] grew around Paris, presumably in botanical gardens. The catalogue is in Latin and French." (Hugh Clarke)

Gerrardanthus/gerrardiana/gerrardii/Gerrardina: for William Tyrer Gerrard (c.1831-1866), a British botanical collector in Natal and Madagascar. He also collected in Australia. He died of yellow fever in Madagascar. The genus Gerrardanthus in the Cucurbitaceae was published in 1867 by British botanists George Bentham and William Jackson Hooker, and Gerrardina was published by British botanist Daniel Oliver in 1870. Gerrard is also commemorated with species names in the genera Seemannaralia, Xyris, Searsia, Leucospermum, Hypoxis, Cuscuta, Teclea, Syzygium, Cynanchum, Secamone, Brachystelma, Emplectanthus, Salacia, Strychnos, Trachyandra, Garcinia and many others. (CRC World Dictionary of Plant Names)

gerstneri: for Father Jacob Gerstner (1888-1948), Bavarian botanist and Roman Catholic missionary, first collector of Aloe gerstneri in Zululand in 1933. (Etymological Dictionary of Succulent Plant Names)

gesineae: for Mrs. Gesina de Boer-Weyer (fl. 1953), wife of Dutch Lithops specialist H.W. de Boer, not surprisingly commemorated with Lithops gesineae. (Etymological Dictionary of Succulent Plant Names)

gessertianum: for a Mr. Gessert (fl. 1923). The JSTOR database of plant collectors includes a Ferdinand Gessert (fl. 1902), who collected in Namibia, but whether this is the same Gessert is anyone'e guess, however I did find a source (The Geographical Journal, Vol. 10, by John Scott Keltie), that mentions a Ferdinand Gessert who was a settler in German South-West Africa (Namibia) around 1896. The website "Biographies of Namibian Personalities" gives his dates as 1870-1953 and says: "Ferdinand Gessert was ... educated in Elberfeld in Germany. He studied in Heidelberg and Berlin. He travelled in 1894 to Cape Town and from there to Namibia. He became farmer on the farms "Inachab" (which he bought from Paul Frederiks in 1894) and "Sandverhaar." He undertook a study trip to Egypt to study irrigation methods. He did extensive experiments in irrigation agriculture under the extreme conditions of southern Namibia and was author of many articles on the subject. He was a Member of the Landesrat before 1915." The taxon Psilocaulon gessertianum was published in 1928 by the German botanists Moritz Kurt Dinter and Martin Heinrich Gustav Schwantes. (Etymological Dictionary of Succulent Plant Names)

giesii/giessii : for Johan Wilhelm Heinrich Giess (1910-2000). Born in Germany he travelled with his parents at the age of 16 to South-West Africa (presently Namibia). He studied botany while interned during WWII, then became a plant collector for the University of Stellenbosch. In 1953 he became the curator at the national herbarium in Windhoek, to which he donated his 18,000+ specimens collected from all over Namibia. He was founding editor of the botanical journal Dinteria (1968-1991), the first issue of which was published in honor of Professor Kurt Dinter on the 100th anniversary of his birth, and also compiled a Preliminary Vegetation Map of South-West Africa (1971) and was the author of Bibliography of South-West African Botany (1989). Heis commemorated with species names in the genera Crinum, Isoetes, Senecio, Zygophyllum, Salsola, Eragrostis, Lachenalia, Crassula, Jamesbrittenia, Heliotropium, Aizoon and probably others. (Etymological Dictionary of Grasses, Wikipedia)

giffenii: for Professor Malcolm Hutchinson Giffen (1902-?). "Botanist who specialized in South African diatoms and was appointed the first professor of the Botany Department at the University of Fort Hare. He was the first plant collector at the university and considered the founder of the Giffen Herbarium (UFH) which was named in his honour." He collected Trachyandra giffenii and Delosperma giffenii, so presumably they are named for him, and probably also Drosanthemum giffenii. (JSTOR; Etymological Dictionary of Succulent Plant Names)

gilfillanii: for Douglas Flemmer Gilfillan (1865-1948), plant collector and attorney, born in Cradock, Eastern Cape, died at Roodepoort, Transvaal. He is described as being the brother-in-law of Ernest Edward Galpin,but in truth they were married to a pair of sisters named de Jongh, Gilfillan to Sophia Magdalena, and Ernest Edward to Marie Elizabeth. When war broke out in 1899, he was part of the formation of the Imperial Light Horse, and was involved in the relief of Ladysmith and other operations. At one time he was condemned to death but his sentence was changed to a fine. He helped to found the Wildlife Protection Society. He was a very competent botanist and had a deep love of the veld. His name is remembered with the taxa Afrocanthium gilfillanii and Euryops gilfillanii and the former taxa Hermannia gilfillanii (now H. filifolia) and Zygophyllum gilfillanii (now Z. lichtensteinianum).

He was the co-author with Heinrich Gustav Adolf Engler of Syllabus der Pflanzenfamilien and Das Pflanzenreich. He would appear to be the honoree for Pelargonium gilgianum, Maerua gilgii and some other taxa that are now consigned to synonymy. The genus Gilgiochloa, which does not appear in southern Africa, was named for him. (Hugh Clarke, pers. comm.; Timber Press Dictionary of Plant Names; Wikipedia)

He was a successful merino sheep farmer, and made a considerable fortune which he used for the creation of what would become Gill College. He is commemorated with Erica gillii, Rapanea gilliana and the former taxa Selago gillii (now S. myrtifolia), Aspalathus gillii (now A. setacea) and Crassula gillii (now Crassula montana), specimens of which were received with the Gill College Herbarium presented to the Albany Museum by the Gill College Trustees. (Gunn & Codd); (2) George A. Gill (fl. 1920), principal of Grootfontein College of Agriculture at Middelburg, and then associated with the Cedara Agricultural College, Natal, commemorated with the former taxon Sporobolus gillii, collected in the Cape Province in 1923 and 1924 and published in 1927 by South African botanist Sydney Margaret Stent, now synonymized to Sporobolus ioclados.

Forced to leave the UK due to bad health, he lived in Argentina and other South American countries in the 1820's. During this time he was in constant contact via letters with many of the leading botanists of his day, including Robert Brown, Hooker, John Lindley, H.C. Watson and even the young George Bentham. He sent them plants and biogeographical information, they sent him books. He returned to Scotland in January 1829." He is commemorated with Caesalpinia gilliesii. Was he related to the John Gillies (1747-1836) who was a Scottish historian and classical scholar? (Sara Scharf, PhD candidate, University of Toronto, pers. comm.)

gillilandiorum: for Hamish Boyd Gilliland (1911-1965), South African botanist, and his wife, M.G. Gilliland (Margaret, more fondly known as Mrs G, or Rita).  Born in Rhodesia, he studied at the University of Edinburgh and at the British Museum of Natural History, and then received an advanced degree from the University of Witwatersrand in 1947. During the war he had been a Captain in the S.A. Signal Corps. and then Major in the S.A. Artillery. He went to Singapore in 1955 where he held the Chair of Botany at the University of Malaya. When that institution divided into two institutions, he remained with what became the University of Singapore. His chief interest was in the Poaceae and he published Grasses of Malaya as Volume 3 of the Flora of Malaya. He was also trustee on the Singapore Nature Reserves Board. In 1965 he was struck by a serious respiratory illness and was forced to leave Singapore and relocate in South Africa where he took up a position in the Botany Department of the University of Natal at Pietermaritzburg. Unfortunately there was a recurrence of his illness and he died soon thereafter. Before going to Singapore he started the Flora of the Witwatersrand which is still in the process of being published. His wife Margaret was a highly-respected botanist in her own right in the Department of Botany, University of Natal, Pietermaritzburg, and received a PhD after turning eighty. The taxon Peristrophe gillilandiorum was published in 1985 by Professor Kevin Balkwill. (Kevin Balkwill, pers. comm.; "H. B. Gilliland, 1911-1965. An Appreciation" by J. Purseglove & H. M.

Mr. Francis Masson, a famous botanist, named this plant in 1797 with the specific epithet to honor Gordon, a soldier, explorer, naturalist and artist/illustrator who named the Orange River, introduced Merino sheep to the Cape Colony, and later committed suicide in Cape Town. Gordon served with the Scots Brigade and then joined the Dutch East India Company, rising to the rank of colonel and commanding the Cape garrison between 1780 and 1795. He undertook numerous expeditions, first with Carl Peter Thunberg and Francis Masson, then with the botanist William Paterson and Johannes Schumacher. He is the subject of Robert Jacob Gordon 1743-1795 The Man and his Travels at the Cape by Patrick Cullinan. The taxon was later (1830) transferred into Hoodia by British botanist Robert Sweet. (PlantzAfrica)

Gorskia/gorskiana: for Stanislaw Batys Górski (1802-1864), Polish botanist, entomologist, physician and pharmacist, head of the botanical garden at Vilnius University. The taxon in southern Africa which is now Guibourtia conjugata was at various times called Gorskia conjugata, Copaifera gorskia and Copaifera gorskiana. The genus Gorskia in the Fabaceae was published in 1861 by German botanist Carl August Bolle. (David Hollombe, pers. comm.)

(CRC World Dictionary of Plant Names)

gossweileri: for John Gossweiler (1873-1952), Swiss-born Angolan botanist and plant collector. He is certainly commemorated with the former taxa Caralluma gossweileri (now synonymized to Orbea huillensis), Pennisetum gossweileri (now P. purpureum), and Miscanthidium gossweileri (now Miscanthus junceus), and Lannea gossweileri, Wedelia gossweileri (now Blainvillea gayana) and Sutera gossweileri (now Jamesbrittenia heucherifolia) were all collected in Angola so they probably honor him as well.

gouanii: for Antoine Gouan (1733-1821), French botanist and professor of botany, correspondent of Linnaeus, authored the Hortus Regius Monspeliensis, the first French botanical book that followed the binomial nomenclature of Linnaeus. He planted the first Ginkgo biloba in France which is supposedly still standing in the Botanical Garden of Montpelier. He is commemorated with Conyza gouanii, published in 1837. (Wikipedia)

goudotii: my only clue about this name is that there was a plant collector and naturalist named Jules Prosper Goudot (?-1842) who collected in Morocco, Tangier, and Madagascar. He travelled as a naturalist in Africa funded by the Paris Museum of Natural History. He died in Madagascar. The taxon in southern Africa that has this name is Pellaea goudotii, collected in 1912 in Madagascar by French botanist Joseph Marie Henry Alfred Perrier de la Bâthie (1873–1958) and published in 1906 by Danish botanist Carl Frederick Albert Christensen. Jules Prosper Goudot collected plants, fishes and insects for the Paris Museum and had a brother who was also a naturalist named Justin-Marie who died in 1848. There are dozens of other taxa with the specific epithet goudotii at least some of which were collected by J. Goudot and presumably named for him.

gouwsii: for Professor Joseph (Jozef) Benjamin Gouws (1909-?), South African botanist and plant collector in Southern Africa. He graduated from the Department of Botany at the University of Pretoria and his dissertation was entitled "An ecological study of the flora in and around Loskop at Waterval Boven." He is commemorated with the former taxon Crinum gouwsii, now synonymized to C. macowanii. For the holotype specimen, collected in 1953 by American botanist Hamilton P. Traub, JSTOR has the following note under locality: "One of a group of plants grown at Arcadia, Calif. from seeds raised by Dr. J.B. Gouws. at the University of Pretoria from plants collected at Duiwelskloof, Northern Transvaal. Seeds received May 6, 1950. First plants flowered August 5, 1953."

govaertsii: for Raphaël Herman Anna Govaerts (1968- ), Belgian botanist and plant collector. He worked as a researcher and curator at Kew Gardens, and is an authority on the Euphorbiaceae, and is commemorated with the taxon Clutia govaertsii. (Kew: World Checklist of Selected Plant Families)

Graderia: anagram of Gerardia. The genus Graderia in the Orobanchaceae (formerly Scrophulariaceae) was published in 1846 by George Bentham. This is the second anagram I have encountered of Gerardia, and both Graderia and Gerardia were published by Bentham. (CRC World Dictionary of Plant Names)

graessneri: probably for Richard Grässner (1875-1942), German cactus enthusiast and nurseryman. The taxa in southern Africa with this specific epithet are Conophytum graessneri and the former Cheiridopsis graessneri, now synonymized to C. brownii. (Etymological Dictionary of Succulent Plant Names)

grahamiana/grahamii: for Robert C. Graham (1786-1845), Scottish physician and botanist, first Regius Professor of Botany at the University of Glasgow, was involved in laying out the new Glasgow Royal Botanic Institution's gardens at Sandyford, then was Regius Professor of Botany and Keeper of the King's Garden at the University of Edinburgh, first President of the Botanical Society of Edinburgh, a President of the Royal College of Physicians of Edinburgh, and a President of the Medico-Chirurgical Society, wrote descriptions of new and rare plants cultivated in the gardens which were published in Edinburgh New Philosophical Magazine, Curtis's Botanical Magazine and Hooker's Companion to the Botanical Magazine. He is commemorated with Flemingia grahamiana and Manihot grahamii. (Flora of Zimbabwe; David Hollombe, pers. comm.)

Grangea: this is one of the mysterious ones, and no certain derivation is available. The genus Grangea in the Asteraceae was published in 1763 by French naturalist Michel Adanson in Families des Plantes, Vol. 1, with no information as to its derivation. W.P.U. Jackson says about the derivation of the name: "Unknown. Probably after a person called Grange, known to Adanson, the namer." Hortus Britannicus by John Claudius Loudon says "Grange, probably a man's name." A correspondent in Berlin who shares my interest in eponymy put me onto the name Claude Granger as the honoree for both the genus Grangeria (which does not appear in southern Africa) and the genus Grangea which does. Claude Granger, apparently the same individual as the person who was sometimes named Tourtechot or Nicolas Granger, Tourtechot (de) Granger, or N. Granger (although the Wikipedia article that says this does not give Claude as one of his names), was a French physician in Tunis for several years who had an interest in natural history (and according to Wikipedia was born sometime in the 1680s in Dijon and died in 1734 in Basra). Nicholas Granger was author of Relation du voyage fait en Egypte, par le sieur Granger, en l'année 1730, published in 1745, sometimes listed as having been written by Tourtechot. He made several trips to Libya, Egypt, Crete and other Middle Eastern regions, and died near Basra either in 1734 or 1737. However her source, an 1852 work published in Wiesbaden by Dr. Georg Christoph Wittstein entitled Etymologisch-botanisches Handwörterbuch, which does credit N. Granger as the source for Grangeria, does not indicate that someone named Granger was commemorated by the generic epithet Grangea, and it seems to me unlikely although possible that Adanson would have turned the name Granger into Grangea. The CRC World Dictionary of Plant Names for the genus Grangeria says simply "For a botanist and gardener named Granger, d. 1737 in Persia," but that work does not include the genus Grangea. Gledhill in The Names of Plants which lists both genera does not provide a link between their derivations. But David Hollombe has provided the following: "Adanson also liked to use simplified spellings. If Granger had sent quantities of seeds back to Paris, as Jussieu indicates, it's possible that Adanson knew of him and named Grangea after him." Wikipedia has the following information about Tourtechot-Granger: "In the 1720s he worked as a physician in a Christian hospital in Tunis, a position he acquired on account of his friend Jean Pierre Pignon, the French consul in Tunis at that time. Moving back to France in 1728, he accompanied Dignon to Egypt in 1731, when Pignon was assigned French Consul in Cairo. During his stay in Egypt, Granger travelled up the Nile to Aswan, documenting a large number of ancient monuments, as well as a considerable amount of its natural history, including animals, plants and minerals. On his return from Egypt in 1732, Granger received a commission from King Louis XV of France, to travel around the Middle East and acquire any kind of information that could help advance the knowledge of natural history in general. Leaving France in 1733 he managed to visit Crete, Egypt again, Cyprus, Palestine and Syria, but died en route toward Persian, two days march from Basra. Granger's account and notes was published in French in 1745, in German 1751 and in English 1773. The flower Grangeria of the family Chrysobalanaceae is named after him." Another possibility suggested by Hugh Clarke is that the name commemorates Joseph-Louis La Grange (1736-1813), an Italian physicist, mathematician and astronomer who as a member of the French Academy of Sciences could have met Adanson there. Hugh adds "He spent 20 years of his life in Prussia at the request of Frederick II and the balance in France at the request of Louis XVI, where he became Professor of the École Polytechnique. He was called "the greatest mathematician in Europe." A prolific writer, he turned out papers about once a month, and made significant contributions to astronomy, algebra, number theory, pure mathematics, analytical mechanics, etc. His monumental work, among others, was Mécanique analytique (1788)." Since we can't absolutely provide a link between Granger and Grangea, this derivation is unclear, but I think Tourtechot-Granger is the most likely one we have at this point.

(Elsa Pooley; Gunn & Codd); (2) Lt. Col. James Augustus Grant (1827-1892), who accompanied John Hanning Speke on one of his expeditions to explore the region of the Nile in 1860 and collected in Uganda, commemorated with Lefebvrea grantii and Acalypha grantii (now synonymized to A. ornata). (JSTOR)

gratiae: for Grace Violet Britten (1904-1987), botanical assistant at the Albany Museum Herbarium at Grahamstown, and enthusiastic cultivator of indigenous plants, especially succulents. She was a cousin of Lilian Louisa Britten (1886-1952), and is commemorated with Aridaria gratiae, Delosperma gratiae and Faucaria gratiae. 'Gratiae' is from the latinized version of Grace. (Gunn & Codd; Etymological Dictionary of Succulent Plant Names; Women and Cacti)

grauii: for Hans Rudolph Jürke Grau (1937- ), plant taxonomist at the University of Munich. The taxon in southern Africa with this specific epithet is the former Aster grauii, published in 1973 by German botanist Wolfgang Lippert and now synonymized to A. bakerianus.

grayana: for Charles Gray, a plant collector and amateur naturalist in southern India. This is probably Charles Thomas Campbell Gray, born at Coonoor in 1861 and died at Ootacamund in 1916. He was the first person to grow Gladiolus in India during the 19th century. The taxon in question here is Parmelia grayana. (David Hollombe, pers. comm.)

greatheadii: for Dr. John Baldwin Smithson Greathead (1854-1910), South African surgeon, game hunter, naturalist and photographer, collected the first specimen of Aloe greatheadii with Selmar Schönland during their hunting expedition to Botswana. (PlantzAfrica)

Green (fl. 1880), commemorated with Aloe greenii and Haworthia greenii. (Etymological Dictionary of Succulent Plant Names)

greenstockii: for Canon William Greenstock (1830?-1912), clergyman, teacher and plant collector, born in England, died in Thailand. He began his priestly work at the Cape in 1856 when stationed at Keiskammahoek Mission and remained in the Eastern Cape until 1874. He went to the Northern Transvaal where he did the bulk of his collecting, then returned to Natal. One of his accoomplishments was to translate the prayer book into the Xhosa language. He is commemorated with Crossandra greenstockii and the former Ipomoea greenstockii, now synonymized to I. crassipes. (Elsa Pooley; Gunn & Codd)

greenwayi/Greenwayodendron: for Percy James (Peter) Greenway (1897-1980), South African botanist and plant collector in Malawi and Zimbabwe, co-author of Kenya Trees and Shrubs, received a Doctor of Science degree in 1954 from the University of the Witwatersrand. He also collected in Kenya, Tanzania, and Zambia. He was a botanist with the East African Agricultural Research Station at Amani, Tanzania 1927-1950. The taxon in southern Africa that has this specific epithet is Sporobolus greenwayi, published in 1963. The genus Greenwayodendron in the Annonaceae was published in 1969 by British botanist Bernard Verdcourt. (Etymological Dictionary of Grasses; Dictionary of British and Irish Botanists and Horticulturists)

gregoriana: for Neil MacGregor of Nieuwouldtville, Merino sheep farmer and authority on Namaqualand flowers who gives tours on his farm called Glen Lyon, commemorated with Gethyllis gregoriana.

grenvilleae: most sources indicate that this epithet is named for Lord William Wyndham Grenville (1759-1834), son of Whig Prime Minister George Grenville and himself Prime Minister from 1806 to 1807. At his house called Dropmore he had a pinetum (an arboretum specializing in growing conifers) which at the time of his death contained the biggest collection of conifer species in Britain. He had seeds (some sources say roots) of the taxon which came to be named Pelargonium grenvilleae sent to him from Namaqualand in 1810 and introduced this taxon into England. David Victor, the International Cultivar Registrar for Geranium and Erodium, President of the Saxifrage Society and the Geranium Group of the Hardy Plant Society, has kindly provided me with this history of the epithet: "The name was first published by Henry Andrews in his Monograph of Geraniums in 1811, as Geranium grenvilleae.  According to him it was named in honour of Lord W. W. Grenville by whom it was introduced to England in the summer of 1810.  Sweet, at tab 262 of his "Geraniaceae" (but under the name Geranium grenvilliae), in 1825 created a new genus, Grenvillea, with this as the type, Grenvillea conspicua.  By the time Harvey came to write his Flora Capensis in 1860, this approach to Pelargonium had been abandoned and he amended the species to be Pelargonium grenvilleae.  This is the name by which it is now known, including under the most recent monograph by Betty Marais." Mr. Victor says further that the additional information that George Don who converted Grenvillea conspicua to Pelargonium conspicuum contradicts Marais and says that Grenvillea was "named in compliment to Lady Grenville, a great lover of Geraniums".  This is further indicated in Paxton and Lindley's Pocket Botanical Dictionary and Sweet's Hortus Britannicus. Lady Grenville (1773-1863), (formerly Anne Pitt, niece of William Pitt the Younger and daughter of Thomas Pitt, Lord Camelford), who lived 29 years after her husband's death was known as an avid gardener and could very well have been honored by this name. If this is the case, it would explain why it should have a specific epithet with a femine (i.e. 'ae') ending. If it was named for Lord Grenville, the epithet should probably be changed to grenvillei. I will continue to investigate this further, and I thank Mr. Victor for his investigations in this matter. UPDATE: Mr. Victor has provided me with the additional information that the original description of the plant now called Pelargonium grenvilleae is in A Monograph of the Genus Geranium (London 1805-1806 2 vols.) by Henry Charles Andrews, and "that the plant was brought to England in 1810 by Lord Grenville and that he (Andrews) named it in his honour." He also says that "The plant described by Bettie [Marais] as P. grenvilleae does not match the plant originally described in a number of respects.  Although she acknowledges that to be the case, she has not supplied a new name and that may be the reason she has decided not to do anything about the original name." (David Victor, pers. comm.; Wikipedia)

Grevea: for "a Monsieur H. Grevé (?-1895), a French plant collector who discovered the type species on the banks of the Mouroundava River in Madagascar probably in 1883, and gave it to Henry Ernest Baillon, French botanist and professor of natural history, who published the genus in the family Montiniaceae and named the species Grevea madagascariensis in his honor in 1884. He was a significant collector, and collected pants for the noted French naturalist and explorer Alfred Grandidier for twenty years. Tropicos lists 123 species collected by him in Madagascar and JSTOR lists at least 18 taxa collected by him that have the specific epithet greveana, greveanus or greveanum. He was the son of an assistant at the museum of St.-Denis on Réunion. Hugh Clarke adds: "Many of his plant collections were made in or near Grandidier's fossil excavations at Ankevo and Bélo, Madagascar.  Grevé settled at Morondava and married the daughter of a Sakalava chief; raised cattle and crops and served as representative for the Messageries Maritimes, a French merchant shipping company.  In 1895 during the second Franco-Hova War against the island's Merina aristocrats, seeking to restore property confiscated from French residents, Grevé was taken prisoner by Hova soldiers and shot on orders of the Hova military government." (Hugh Clarke; Tropicos; JSTOR)

Grevillea: for Charles Francis Greville (1749-1809), English horticulturist who introduced and grew many rare plants 14 of which were illustrated in Curtis’s Botanical Magazine, Fellow and Vice-President of the Royal Society, Fellow of the Linnean Society, member of Parliament and a Lord of the Admiralty. The genus Grevillea in the Proteaceae was published in 1810 by British botanist Robert Green. (CRC World Dictionary of Plant Names)

Grewia: for Nehemiah Grew (1641-1712), British botanist and physiologist, physician and microscopist, Fellow of the Royal Society, a pioneer in exploring the physiology of plants, and one of the founders of the science of plant anatomy. He is considered along with Marcello Malpighi to be the founder of the science of plant anatomy. He was the author of Anatomy of Plants published in 1682. Swedish botanist Carl Linneaus published the genus Grewia in the Malvaceae in 1753. (CRC World Dictionary of Plant Names)

greyi/greyii: for Sir Frederick William Grey (1805-1878), Prime Minister of England, admiral and plant collector in South Africa and Angola, commemorated with Phylica grewii and Erica greyi. (Gunn & Codd)

Greyia: for Sir George Grey (1812-1898), who was the governor of South Australia, the Cape Colony and New Zealand in the second part of the 19th century. He was also a great patron of botany and an explorer, and Flora Capensis was dedicated to him, as were the town of Greytown in Natal and Grey College at Bloemfontein. The genus Greyia in the Greyiaceae was published in 1859 by British botanists William Jackson Hooker and William Henry Harvey. (CRC World Dictionary of Plant Names; Gunn & Codd)

Grimmia: for Dr. Johann Friedrich Karl (Carl) Grimm (1737-1821), German botanist and physician to the Duke of Saxe-Gotha. He translated the works of Hippocrates in 4 vols. The genus Grimmia in the Grimmiaceae was originally named by German botanist Jakob Friedrich Ehrhart and published by his fellow countrymen the botanist Johann Hedwig in 1801. (Bryophyte Flora of North America)

grimmii: for Hans Grimm (1875-1959), German novelist, short story writer and essayist, commemorated with Herniaria grimmii, which was collected by Ernst Edward Galpin in 1904 in South Africa. He went to Port Elizabeth in 1897, set up as some kind of a merchant in East London in 1901 and after spending a number of years in South-West Africa he returned to Germany in 1910. He became the leading propagandist for the restoration of the former German colonies and especially of South-West Africa, which he visited in 1927-8, and one of the leading writers of the Third Reich. As far as I can tell he had no connection with botany, and I have no idea why Galpin honored him with this species name. He may have just been an acquaintance of Galpin's. (David Hollombe, pers. comm.)

grisbrookii: for Charles Fleetwood Southey Grisbrook (1843-1902), son of Charles Hewson Grisbrook (1799-1876) who was an English medical practitioner and pharmacist who settled in South Africa and studied medicine under Dr. John Atherstone. The younger Grisbrook collected Erica grisbrookii near Caledon in 1894 and the taxon published in his honor in 1895 by South African botanists Francis Guthrie and Harry Bolus. (Gunn & Codd)

Grisebachia/grisebachiana: for August Heinrich Rudolph Grisebach (1814-1879), German botanist who was a phytogeographer (i.e. a person who studies the geography of plant distribution), professor on the university medical faculty at Göttingen, pioneer in plant systematics, plant collector and taxonomist, Fellow of the Linnean Society, author of Genera et Species Gentianearum (1838), Die Vegetation der Erde (1872) and Flora of the British West Indian Islands (1864), and Director of the Botanical Garden of Göttingen. He followed in the footsteps of his uncle (a professor of botany), explored the island of Cuba, travelled extensively throughout the Balkan region, and worked on the botany of South America. The genus Grisebachia in the Arecaceae is an invalid taxon, but the Grisebachia in the Ericaceae was published in 1838 by German pharmacist and botanist Johann Friedrich Klotzsch. Grisebach was also commemorated with the southern African taxon Sebaea grisebachiana. (CRC World Dictionary of Plant Names)

grobleri: probably for Paul Johan Grobler (1937- ), South African botanist, Assistant Director of the National Botanical Gardens at Kirstenbosch. Aspalathus grobleri was published in 1968 by Swedish-Danish botanist Rolf Martin Theodor Dahlgren. Some evidence for this conclusion is that according to an entry in JSTOR Aspalathus grobleri is restricted to the clayey flats of the Swellendam region, and P.J. Grobler and J. Marais published an article in 1967 called "Die Plantegroei van die Bontebok Nationale Park, Swellendam," and J. Marais collected the isotype in Bontebok National Park in 1966. (Gunn & Codd)

groenewaldii: for Barend Hermanus Groenewald (1905-1976), South African amateur aloe specialist and plant name author, commemorated with Euphorbia groenewaldii, collected by Groenewald in 1938 in Pietersberg District and published in 1938 by South African botanist Robert Allen Dyer. (JSTOR)

grossartii: the taxa in southern Africa with this specific epithet are the former Brachystelma grossartii, now synonymized to B. arnotii, and Polycarpaea grossartii, now P. eriantha, with no information as to its derivation. One possibility is Dr. William Grossart, Scottish surgeon and geologist, who was interested in determining coal bed strata in Scotland and used fossil plants as one of the determinants, but this is a very long shot.

Grossera: for Wilhelm Carl Heinrich Grosser (1869-1942), German botanist. He contributed to Das Pflanzenreich by Heinrich Gustav Adolf Engler. The genus Grossera in the Euphorbiaceae was published in 1903 by German botanist and entomologist Ferdinand Albin Pax. (CRC World Dictionary of Plant Names)

Grubbia: for Michael (Mikael) Grubb (af Grubbens) (1728-1808), Swedish botanist, minerologist, banker and merchant, traveller and botanical collector at the Cape who purchased specimens of dried plants at the Cape and gave them to Prof. Peter Jonas Bergius, former pupil of Linnaeus, who published the genus Grubbia in the Grubbiaceae in 1767. He was elected a member of the Swedish Royal Academy of Sciences in 1767, but later expelled. He was Director of the Swedish East India Company. He went to China for the first time in 1749 and stayed in Canton for a couple of years. He was several times declared to be bankrupt due to shady business dealings. Regrettably, it was later revealed that much of the collection that he had presented to Bergius had actually been collected by the German gardener and botanical collector Johann Andreas Auge and had been purchased by Grubb. Bergius used much of this collection in his Descriptiones plantarum, his only major work, and referred in glowing terms to Grubb when he dedicated the book to him and named the genus in his honor. It was only later when Carl Peter Thunberg published his Travels at the Cape of Good Hope that the truth came out. Peter MacOwan in the 1887 Transactions of the South African Philosophical Society referred to him as "the perfidious Grubb." Interestingly, a short entry on Michael Grubb and the East India Company on the website of the Bergius Botanic Garden and Herbarium does not allude to his purchase of much of the collection. (Gunn & Codd)

Guatteria: for Giovanni Battista Guatteri (1739/1743-1793), Italian botanist, Jesuit abbot, and professor of botany, founder of the New Botanical Garden of Parma. Hugh Clarke adds "After ten years study at the Universities of Parma and Padua, he became a professor of botany at Parma (1769). Guatteri revitalized botanical teaching by focusing on the direct study of plants instead of Greek and Arabic texts, used the most modern botanical texts by Gómez de Ortega (which he translated) and Bodoni, adopted the new classification system of Linnaeus, and, over years, completely renovated the University’s botanical garden to make it among the best in the world. He was also Inspector of Mines and Fossils for the Duchy, gave advice on scientific land management and promoted the artificial cultivation of mushrooms." The genus Guatteria in the Annonaceae was published in 1794 by Spanish botanists Hipólito Ruiz López and José Antonio Pavon. (CRC World Dictionary of Plant Names; Hugh Clarke)

gueinzii: for Wilhelm Gueinzius (1813/1814-1874), German apothecary and naturalist in KwaZulu-Natal, botanical and zoological collector, and first resident botanist in Natal. He first became acquainted with the founder of the zoological museum in Leipzig, Professor Eduard Friedrich Pöppig, under whom he trained and to whom he eventually sent many of his collections from South Africa. It was in 1838 that he went to the Cape Colony and registered as a pharmacist. The state of travel in South Africa in those days is indicated by the fact that on his second trip to Natal, it took him 16 days by schooner to get there from Cape Town. He had to sell his collected ornithological and entomological specimens for money to live on. He apparently lived a somewhat lonesome hermit life and shared his home with a python. In addition to plants, he collected marine algae, mosses and ferns, bats, snakes and insects. He is commemorated in many species names such as Gladiolus gueinzii, Psoralea gueinzii, Eugenia gueinzii, Barleria gueinzii, Searsia gueinzii, Leucospermum gueinzii, Keetia gueinzii, Fabronia gueinzii, and in former taxa in genera Vittaria, Combretum, Disa and Asplenium. (Elsa Pooley; Gunn & Codd; PlantzAfrica; Wikipedia)

guerichiana/guerichianum/guerichii: for Georg Julius Ernst Gürich (Guerich) (1859-1938), German geologist, paleontologist and botanist, university teacher, and plant collector in South-West Africa 1885-1888, Director of the Geological-Minerological Institute in Hamburg, expedition to East Africa in 1914, interned in South Africa during World War I, after the war became Professor of Geology and Paleontology. In addition to his travels in the German colonies of Africa, he he travelled widely in Europe, Australia, Venezuela and Alaska. He is commemorated in the species names Euphorbia guerichiana, Ficus guerichiana, Sesamothamnus guerichii, Mesembryanthemum guerichianum, and the former taxon Sterculia guerichii (now S. africana). In addition there are other taxa that may relate to him such as Polygala guerichiana, Merremia guerichii and Phragmanthera guerichii. (Gunn & Codd; JSTOR)

guerkeana/guerkei: for Robert Louis August Maximilian Gürke (Guerke) (1854-1911), German botanist, plant collector, and prominent taxonomist of the Cactaceae. He named an incredible number of taxa, and is commemorated with Royena guerkei. Other taxa in southern Africa that bear this specific epithet and probably honor R.L.A.M. Gürke are Hermannia guerkeana and Justicia guerkeana. (Trees and Shrubs of Mpumalanga and Kruger National Park; Sappi What's in a Name: The Meanings of the Botanical Names of Trees)

guerranum: possibly for Guilherme Guerra, Director of Agriculture and Forests, Luanda Prov., Angola, commemorated with Indigastrum guerranum. This taxon was collected in Angola in 1956 and 1957 by someone named Teixeira, probably J.M. Brito Teixeira (fl. 1950-1967), and published in 1992 by Brian David Schrire.

Guettarda: for Jean Étienne Guettard (1715-1786), French physician, naturalist, botanist and minerologist, a member of the Faculty of Medicine at Paris (1742) and one time médecin botaniste to the French Prince Louis, Duc d'Orleans (1747-1752). He mapped the minerological distributions of much of Europe, and was one of the first scientists to notice the relationship between the distribution of plants and that of soils and subsoils. The genus Guettarda in the Rubiaceae was published in 1753 by Swedish botanist Carl Linnaeus. (CRC World Dictionary of Plant Names; Online Encyclopedia; Encyclopedia.com)

Guibourtia: for Nicholas Jean Baptiste Gaston Guibourt (1790-1861), French pharmacologist and professor of pharmacology at the Ecole de Pharmacie, Paris, author of Histoire abrégée des Drogues simples (a history of plants used for extracting drugs), founder and popularizer of the study of materia medica in France, that is, homeopathic medicines. He published extensively on exotic woods and natural dyes. His date of death is often given as 1867. The genus Guibourtia in the Fabaceae was published in 1857 by British botanist John Joseph Bennett. (CRC World Dictionary of Plant Names; The Names of Plants, 4th ed.)

Guilandina: for Melchior Guilandinus (aka Melchior Wieland) (1519/1520-1589), Prussian healer and naturalist, scholar, traveller, botanist, professor at the University of Padua and Praefectus of the Botanical Garden there. He is one of the authors of the Medecina Aegyptiorum. "Guilandinus was born in poor circumstances in Königsberg. He studied Greek, Latin and philosophy. He always had a great passion for natural history. Later he studied botany and pharmacology in Rome and became the protégée of Senator Marino Cavalli, the ambassador of Venice. He was a member of the board of the University of Padova. Guilandinus made journeys to Syria, Palestine and Egypt, with financial assistance and letters of recommendation of Cavalli. He was captured by pirates and held prisoner for many years. Finally, he was liberated by the Ptolians physician Gabriele Fallopio. In 1561, he was asked to become the second director of the Botanical garden at Padua. He was reappointed several times to the chair of lecturer and demonstrator of medicinal herbs, presumably at the University of Padua, a position he held until his death." (Dictionary of Medical Science by Robley Dunglison) The genus Guilandina in the Fabaceae was published by Swedish botanist Carl Linnaeus in 1753. (CRC World Dictionary of Plant Names)

guilelmi-trollii: for Wilhelm Julius Georg Hubertius Troll (1897-1978), botanist, authority on plant morphology, member of the German Academy of Sciences - Leopoldina, professor at the Universities of Munich, Halle, and Mainz, author of Vergleichende Morphologie der höheren Pflanzen, Vols. 1–3 (1967, Praktische Einführung in die Pflanzenmorphologie, Parts 1–2 (1954–57), Die Infloreszenzen, Vols. 1–2 (1964–69, and Allgemeine Botanik, 4th ed. (1973), commemorated with the former taxon Crassula guilelmi-trollii, published in 1959 by Klaus Dieter Stopp and now synonymized to Crassula hirsuta. He used the term Gestalt to describe the overall or outer appearance or form of a plant, and may have been the first to do so. He was the older brother of the German geographer and botanist Professor Dr. Carl Troll (1899-1975). (David Hollombe, pers. comm.; The Free Dictionary)

guilelmi-waldemarii: for Friedrich Wilhelm Waldemar (1817-1849), Prince of Prussia, son of Frederick William II of Prussia and Frederika Louisa of Hesse-Darmstadt. He is commemorated with the former taxon Vinca guilelmi-waldemarii, now synonymized to Catharanthus roseus. (David Hollombe, pers. comm.)

guillarmodiae: for Amy Jacot Guillarmod (1911-1992), South African botanist and limnologist, noted for her work on the flora of Basutoland and some 200 publications, including numerous papers on wetlands, bogs and sponges. She was a plant pathologist in the Division of Botany and Plant Pathology of the Department of Agriculture in Pretoria, Head of the Botany Department of the Pius XII College in Roma, Lesotho, and lecturer in the Botany Department of Rhodes University. She played hockey for Northern Transvaal, and is commemorated with Merxmuellera guillarmodiae. (Etymological Dictionary of Grasses; Wikipedia)

guillauminii: for Prof. André Louis Joseph Edmond Armand Guillaumin (1885-1974), French botanist who worked at the Muséum National d'Histoire Naturelle in Paris, starting as a preparer in 1909, then assistant to the chair of botany and plant physiology and later head of the department. He eventually became the deputy director of the museum from 1947 to 1950 and retired in 1956. He was the author of Useful and Ornamental Trees and Shrubs (1928) and The Flowers for Gardens in 4 volumes (1929 to 1936). He also contributed major sections to Flowers of Indochina. The taxon in southern Africa that once had this specific epithet was Kalanchoe guillauminii, now synonymized to K. rotundifolia. There are almost 24 taxa with this specific epithet. (David Hollombe, pers. comm.)

Guilleminea: for Jean Baptiste Antoine Guillemin (1796-1842), French botanist, traveller and author. He studied with Jean Pierre Étienne Vaucher (1763-1841) and Augustin Pyramus de Candolle (1778-1841), and later became curator of the herbarium and library of botanist Jules Paul Benjamin Delessert (1773-1784). In 1827 he worked as an aide-préparateur at the Muséum national d'histoire naturelle, and in 1834 he succeeded Adolphe Brongniart (1801-1876) as an assistant naturalist to the chair of botany. He was co-author with Achille Richard and George Samuel Perrottet of a work on the flora of Senegambia (present-day Senegal and Gambia) titled Florae Senegambiae Tentamen (1830-1833). The genus Guilleminea was published in 1823 by German botanist Karl Sigismund Kunth. (CRC World Dictionary of Plant Names; Wikipedia)

Guizotia: for François Pierre Guillaume Guizot (1787-1874), French politician, statesman and historian. After his father was executed in 1794, he was educated in Geneva, then studied law in Paris, but a critical study of Edward Gibbon's classic history of Rome led to his appointment to the chair of modern history at the University of Paris. In and out of government, he eventually became Minister of Interior and then Minister of Public Instruction, where he managed to pass a law requiring every commune to have a public primary school. He rose to ambassador, foreign minister and finally premier, but was overthrown and forced into exile in Britain. The website Book Rags says "Guizot's histories have been justly praised for their excellent scholarship, lucid and succinct style, judicious analysis, and impartiality." The genus Guizotia in the Asteraceae was published in 1829 by French botanist and naturalist Alexandre Henri Gabriel de Cassini. (CRC World Dictionary of Plant Names)

gulielmi: for Wilhelm Triebner (1883-1957), German plant collector and horticulturist who went to what is now Namibia in 1904, stayed as a succulent gardener and farmer, and established a succulent plant nursery near Windhoek. He collected Lithops gulielmi in Namaqualand. 'Gulielmi' or 'Gulielmus' is Latin for William. (Etymological Dictionary of Succulent Plant Names; JSTOR)

gumbletonii: for William Edward Gumbleton (1840-1911), noted Irish horticulturist. He amassed a comprehensive collection of botanical books which he left to the Irish National Botanic Gardens at Glasnevin. He settled at the family estate of Belgrove on Great Island in Cork Harbor and occupied himself with growing rare and newly-introduced species, especially herbaceous perennials. He had a Buddleia which was the first one of its species to bloom in the British Isles, and he had some 40 species and cultivars of Kniphofia and numerous Begonias and Pelargoniums. The Dictionary of British and Irish Botanists and Horticulturists described him as a dilettante and enthusiastic gardener, and a lady who knew him called him 'small, partly bald, and very pompous." He is commemorated with the taxon Arctotis gumbletonii, which was published in his honor by Joseph Dalton Hooker in 1901, "in tardy recognition of Mr. Gumbleton's services as a raiser and flowerer of many fine new plants." The cultivars Kniphofia 'W.E. Gumbleton' and Azalea 'W.E. Gumbleton' were also named for him. (Wikipedia)

gunillae: for Gunilla (Lindberg) Nordenstam, wife of Swedish botanist Bertil Nordenstam, who published the name Felicia gunillae. He noted that Felicia corresponded to his daughter's name, so felt it appropriate to form the specific epithet from his wife's name. (David Hollombe, pers. comm.)

Gunillaea: for Gunilla Thulin, wife of Swedish botanist Mats Thulin who is the author of the genus Gunillaea in the Campanulaceae published in 1974. (W.P.U. Jackson)

Gunnera: for Johan Ernst Gunnerus (1718-1773), Norwegian clergyman and botanist, Bishop of Trondheim, Norway, and founder of the Trondheim Society which became the Royal Norwegian Society of Sciences and Letters. He was the author of Flora norvegica (1766-1776), and was elected a foreign member of the Royal Swedish Academy of Sciences. He was a professor of theology at the University of Copenhagen. The genus Gunnera in the Gunneraceae was published in 1767 by Swedish botanist Carl Linnaeus. (CRC World Dictionary of Plant Names)

gunniae: for Mary Davidson Gunn (1899-1989), South African librarian and biographer, specializing in the history of botanical collecting in South Africa. The library of the Botanical Research Institute in Pretoria is named the Mary Gunn Library. She was the co-author with Dr. Leslie Edward Wastell Codd of Botanical Exploration of Southern Africa, and with Enid du Plessis of The Flora Capensis of Jakob and Johann Philipp Breyne, and is commemorated with Eriosema gunniae.

Gussonea: for Giovanni Gussone (1787-1866), Italian botanist and physician, Director of the Botanic Garden at Palermo, author of the Catalogus plantarum (1821), Plantae rariores (1826), Florae siculae prodromus (1827-1828) and Florae siculae synopsis (1842-1844). The genus Gussonea in the Orchidaceae was published in 1828 by French botanist and physician Achille Richard. (CRC World Dictionary of Plant Names; Stearn's Dictionary of Plant Names)

Gutenbergia: for Johann (Johannes) Gutenberg (Johann Gensfleisch zur Laden zum Gutenberg) (1400-1468), German goldsmith, printer and publisher, craftsman and inventor of a method of printing using movable type (which was actually invented in China) that was used without important change until the 20th century, best-known for his book, the 42-line Bible, often called the Gutenberg Bible (c.1455). The genus Gutenbergia in the Asteraceae was published in 1840 by German physician and botanist Carl Heinrich 'Bipontinus' Schultz. (Flowering Plants in West Africa by Margaret Steentoft)

guthriae: for Miss Louise Guthrie (1879-1966), botanical assistant, taxonomist and artist at the Bolus Herbarium in Cape Town, daughter of Francis Guthrie, commemorated with Oscularia guthriae, which she collected as Lampranthus guthriae in 1926. (JSTOR)

Guthriea/guthriei: for Francis Guthrie (1831-1899), the South African mathematician and botanist who first posed the Four Color Problem in 1852. At the time, Guthrie was a student of Augustus De Morgan at University College, London. He obtained his B.A. in 1850, and LL.B. in 1852 with first class honors. While coloring a map of the counties of England, he noticed that at least four colors were required so that no two regions sharing a common border were the same color. He postulated that four colors would be sufficient to color any map. This became known as the Four Color Problem, and remained one of the most famous unsolved problems in topology for more than a century, until it was eventually proven in 1976 using a controversial computer-aided proof which was lengthy and inelegant. Guthrie eventually moved to South Africa in 1861 and took up the post of mathematics master at the Graaff-Reinet College. While there he gave some lectures in botany and thus started a lifelong friendship with local resident Harry Bolus. He advised Bolus to take up the study of botany to assuage his grief at the loss of his son. When Bolus left for Cape Town a few years later, he persuaded Guthrie to move there as well. For a while he practiced at the Bar and edited a newspaper before becoming professor of mathematics at the South African College, which later became the University of Cape Town. He remained there from 1876 until he retired in 1898. When Bolus undertook to do the family of Ericaceae for Flora Capensis, he enlisted Guthrie's aid and they collaborated until Guthrie's death. Before his death, Guthrie had made an extensive collection of the Cape Peninsula flora, which was eventually housed as the Guthrie Herbarium in the University of Cape Town Botany Department, and used for teaching and reference. He is commemorated with Delosperma guthriei, Nemesia guthriei, Gladiolus guthriei, Erica guthriei and probably with taxa in Theilera, Diosma, Oxalis, Muraltia, Phylica, Xiphotheca and Indigofera. The genus Guthriea in the Achariaceae was published by South African botanist Harry Bolus in 1873. This ia a monotypic genus with only a single species, Guthriea capensis. (Etymological Dictionary of Succulent Plant Names; Wikipedia)

guthrieae: for Miss Louise Guthrie (1879-1966), botanical assistant, taxonomist and artist at the Bolus Herbarium in Cape Town, daughter of Francis Guthrie, commemorated with Cyrtanthus guthrieae, Thamnochortus guthrieae and the former taxon Leucadendron guthrieae, now synonymized to L. gandogeri. (JSTOR)

gyelniki: for Vilmos Köfaragó Gyelnik (1906-1945), Hungarian botanist, mycologist, lichenologist, and plant collector in Hungary, Sweden and Romania. He received a PhD from Budapest University, worked for a time in Cairo, taught at Budapest University and then worked at the Budapest National Museum, and was killed by Allied bombing of a railway station at Amstetten in March, 1945. He had published about 100 papers and proposed over 1300 new names mostly for lichens. The species in Southern Africa that has this epithet is the former Parmelia gyelniki Dodge now synonymized to Xanthoparmelia subramigera Hale. (HUH; Mushroom: The Journal of Wild Mushrooming; Wikipedia; Biographisch bibliographisches-Handbuch der Lichenologie)

gysbertii: for Gysbert Grisbrook, a relative of Professor Francis Guthrie, who with Harry Bolus wrote an account of Erica for Flora Capensis in 1905, and who discovered Erica gysbertii. (David Hollombe, pers. comm.; Ted Oliver, pers. comm.)



haageana
: for the firm of Friedrich Adolph Haage (1796-1886), which was headed by his great-grandson Walther Haage at the time Haworthia haageana was described. This taxon was published in 1930 by German botanist Karl von Poellnitz and has now been synonymized to Haworthia reticulata. See following entry. (David Hollombe, pers. comm.)

haagei: for Walther Haage (1899-1992), German horticulturist, son of Ferdinand Haage, and after his death owner of the famed Haage Cactus Nursery in Erfurt. He was the author of Kakteen im Heim (Cactus at Home) and several other books on cactus care, and he was an honorary member of the German Cactus Society. This family has a long and storied history in the growing of succulent plants, beginning with gardener and botanist Friedrich Adolf Haage (1796-1866), co-founder of the Erfurt Horticultural Association, his sons Gustav Ferdinand Haage (1830-1921) who took over the firm, Friedrich Ferdinand and Adolph, his grandson Ferdinand Friedrich Adolf Haage (1859-1930), his great-grandson Walther, his great-great-grandson Hans-Friedrich Haage (1942- ), and finally his great-great-great grandson Ulrich (1970- ) who in 1996 took over the company now called Kakteen-Haage. Taxa in southern Africa with this specific epithet are Glottiphyllum haagei and the former Faucaria haagei, now synonymized to F. bosscheana, and Gibbaeum haagei, now G. haaglenii. (Etymological Dictionary of Succulent Plant Names; Kakteen-Haage; Wikipedia)

haaglenii: the taxon in southern Africa that bears this specific epithet is Gibbaeum haaglenii, formerly G. haagei, published in 2001 by German botanist Heidrun Elsbeth Klara Osterwald Hartmann, with no information as to the derivation of its name.

haagnerae: for Mrs. Peggy Haagner (fl. 1986), South African naturalist who found Lavrania haagnerae, published in 1986 by South African naturalist and plant collector Darrel Charles Herbert Plowes. (Etymological Dictionary of Succulent Plant Names; Women and Cacti)

haakonii: for Haakon Bryhn (fl. 1908-1909), Norwegian plant collector of mosses in Zululand. He was the son of Norwegian botanist, physicist and moss authority Niels Bryhn, and is commemorated in the former taxa Leucoloma haakonii (now L. rehmannii), Fissidens haakonii (now F. borgenii) and Campylopus bryhnii (now C. nanophyllus). (Gunn & Codd)

haareri: for Alec Ernest Haarer (1894-1970), English-born Tanzanian plant ecologist working for the District Agricultural Office, plant collector, Fellow of the Linnanean Society, commemorated with Pennisetum haareri, published in 1933 by Austrian botanist Otto Stapf and British botanist Charles Edward Hubbard and now synonymized to P. macrourum. (Etymological Dictionary of Grasses; Dictionary of British and Irish Botanists and Horticulturists)

hackeliana/Hackelochloa: for Eduard Hackel (1850-1926), Bohemian-born Austrian botanist and agrostologist, high school teacher and professor of natural history, one of the authors in 1890 of Die natürlichen Pflanzenfamilien (The True Grasses). He was a world authority on the Poaceae. The taxon in southern Africa with the specific epithet hackeliana is Ipomoea hackeliana, but I haven't found specific confirmation that it was named for Eduard Hackel. The genus Hackelochloa in the Poaceae was published in 1891 by Carl Ernst Otto Kuntze, and it was named for Eduard Hackel. He is also honored with the generic name Hackelia which does not appear in southern Africa. (CRC World Dictionary of Plant Names)

haeckeliana: for Prof. Dr. Ernst Heinrich Philipp August Haeckel (1834-1919), eminent German evolutionary biologist, zoologist, philosopher, physician, artist and illustrator who discovered, described and named thousands of new species, coined such terms of phylum, phylogeny and ecology, and wrote many books and scientific memoirs. He received a doctorate in zoology, became a professor of comparative anatomy, met with such luminaries as Charles Darwin, Thomas Huxley and Charles Lyell. He is commemorated with Aptenia haeckelianaand Platythyra haeckeliana. (Etymological Dictionary of Succulent Plant Names)

haegarthii: for Walter Jacques Haygarth (1862/1863-1950), an engineer, draughtsman and plant collector who worked with John Medley Wood. His father was Joseph Williamson Haygarth who arrived in South Africa in 1852, and whose sister Elizabeth married Wood. His older brother Joseph Harrison Haygarth was a schoolmaster in Lancashire, England. Walter Haygarth was adopted by J.M. Wood. He collected in Natal and East Griqualand, and contributed drawings to Wood's book of plants. He is commemorated with Chlorophytum haygarthii, Ceropegia haygarthii, Streptocarpus haygarthii and the former taxon Pavetta haegarthii, now synonymized to P. cooperi. Other taxa in southern Africa that probably honor him as well, that according to JSTOR records were either collected by him or by Wood, are Eriospermum haygarthii, Senecio haygarthii, Helichrysum haygarthii and Streptocarpus haygarthii. Pavetta haegarthii was published in 1984 by Dutch botanist Cornelis Eliza Bertus Bremekamp with no explanation as to the change in spelling of the name. (Elsa Pooley; Gunn & Codd)

Haenelia: for Eduard Gustav Haenel (Hänel) (1804-1856), a German book publisher and type foundry owner who was active in gardening societies. Hugh Clarke adds the following: "He learned the art of printing from his father Jacob Haenel and in 1824 inherited his father’s print shop and in 1828 brought the Congreve high speed printing press to Germany. In 1830, he founded a font foundry and created a number of polytypes to cater to the burgeoning lithographic press. His printing office acquired extensive fame through their skillful preparation of securities. When Haenel died, the foundry later went over to his colleague Wilhelm Gronau, who retired in 1885." The genus Haenelia in the Asteraceae was published in 1843 by German botanist Wilhelm Gerhard Walpers. (Hugh Clarke)

haeneliae: for Christine Hänel (Haenel), a plant collector of the Desert Ecological Research Unit of Namibia, co-author of Gough Island: A Natural History (2005), commemorated with Raphionacme haeneliae, which she collected in Namibia in 1994, and which was published in 1996 by Dutch botanists Hendrik Johannes Tjaart Venter and Rudolf L. Verhoeven. She has a particular interest in Gough Island, a volcanic island in the South Atlantic which is a dependency of Tristan da Cunha, and published "Gough Island 500 Years After Its Discovery: A Bibliography of Scientific and Popular Literature 1505-2005" in the South African Journal of Science, 2008. (JSTOR)

Hafellia: for Josef Hafellner (1951- ), Austrian mycologist at the Institute of Plant Sciences of the University of Graz. He is co-author with Ingvar Kärnefelt and Volkmar Wirth of Diversity and Ecology of Lichens in Polar and Mountain Ecosystems (2010) and many scientific publications including monographs for the genera Karschia, Letroutia and Brigantiaea. Hugh Clarke adds: "[He] obtained a doctorate at Graz (1978), [and did] post-doctoral studies at Queensland University (1986). He has lectured at Graz from 1983 in systematic botany and geobotany. His main interests include taxonomy of lichenicolous fungi, canopy lichens, taxonomy of vegetatively reproducing of lichens and lichen diversity in Austria, the Alps, Macaronesia, Sonoran Desert, North America and other areas.  He was guest professor at the Ecole Normale Supérieure de St. Cloud (1980, 1982)." He has collected 150,000 specimens of lichens and lichenicolous fungi in Australia, Greece, Italy, Spain, South Africa, the Canary Islands and Madeira, and is an expert on lichens and their parasites. This genus of lichenized fungi in the Physciaceae was published by Klaus Kalb, Helmut Mayrhofer and Christoph Scheidegger in 1986. It's curious that the name they chose was Hafellia and not Hafellnia. (Christoph Scheidegger, pers. comm.; Hugh Clarke)

hafstroemii: for Adolf Hjalmar Frederick Hafström (1871-1948), Swedish judge, botanist and plant collector who collected in South Africa with Swedish botanist John Phillip Harison Acocks in 1934, 1936 and 1938. He has some 80,000 specimens in the Hafström Herbarium of the Riksmuseets Botaniska Avdelning in Stockholm. He collected Osteospermum hafstroemii near Bredasdorp in 1938 and it was published in 1943 by Swedish botanist Nils Tycho Norlindh. (Gunn & Codd)

Hagenia: for Karl Gottfried Hagen (1749-1829), German chemist and professor of chemistry and physics at the University of Königsberg. He founded the first German chemical laboratory and introduced the scientific discipline of pharmaceutical chemistry. His textbooks were used for decades. He was also a doctor, professor of medicine and medical advisor to the provincial health department. The genus Hagenia in the Rosaceae was published in 1791 by German botanist and naturalist Johann Friedrich Gmelin. Hugh Clarke adds: "He founded the first German pharmaceutical (chemical) laboratory and introduced pharmacology as a university-taught discipline. He wrote a Textbook on the Apothecary Art (1778) and Outline of Experimental Chemistry (1786) which Immanuel Kant declared 'a logical masterpiece.' He founded the Beiträge zur Kunde Preußens in 1817 aimed at the popularization of local history and of science." There was also a genus Hagenia in the Caryophyllaceae published in 1794 and a lichen genus Hagenia in the Physciaceae published in 1824 which were probably named for the same person. (Hugh Clarke; Wikipedia)

hahnii: for Dr. Norbert Hahn (1966- ), South African-British botanist and biologist who was expert on flora of the Soutpansberg, commemorated with Aloe hahnii. (David Hollombe, pers. comm.)

The genus Hakea in the Proteaceae was published either in 1797 or 1798 by German botanist and mycologist Heinrich Adolf Schrader. (CRC World Dictionary of Plant Names; Hugh Clarke, pers. comm.)

Halesia: for Stephen Hales (1677-1761), British clergyman, scientist and philanthropist. He was a Fellow of the Royal Society and a member of the Academies of Sciences in Paris and Bologna. He was the author of Vegetable Staticks published in 1727 and Haemastaticks published in 1733. Hugh Clarke adds: "He studied at Cambridge University (M.A. 1703, B.Div. 1711) and was ordained a priest (1709). His did pioneering research in plant physiology (transpiration and root pressure measurement), animal physiology (blood pressure measurements), air quality improvements in mines, ships and prisons through ventilators, distillation of fresh water from sea water, preservation of water and meat on sea-voyages, and the development of surgical forceps for the removal of bladders stones. He was also a philanthropist and spoke out against alcoholic intemperance and the gin trade." The genus Halesia in the Styracaceae was published in 1759 by Swedish botanist Linnaeus in Systema Naturae ed. 10 but seems also to have been published by British naturalist John Ellis in the same publication. Linnaeus may have been crediting Ellis with the publication. (Hugh Clarke)

Hallackia/hallackii: for Russell Hallack (1824-1903), British businessman born in Cambridge, amateur botanist and plant collector who settled in South Africa in 1843 and botanized around Port Elizabeth and who sent collections to Peter McOwan and William Henry Harvey.

He wrote the poem, Die Alpen, while doing botanical research (1932), produced a major work on Swiss flora (1742), and an eight-volume compendium of information on physiology (1747-1766). His publications, numbering in the thousands, guided development in physiology for a century. The genus Halleria in the Scrophulariaceae was published by Swedish botanist Carl Linnaeus in 1753. (CRC World Dictionary of Plant Names, Hugh Clarke, pers. comm.)

Hallia: for Birger Mårten Hall (1741-1841), Swedish botanist and physician. The genus Hallia in the Fabaceae was published in 1813 by French naturalist and artist Jean Henri Jaume Saint-Hilaire. (CRC World Dictionary of Plant Names)

He was a major explorer of Euphorbias in South Africa. He was awarded a Fellow of the Cactus and Succulent Society of America in 1981. The CRC World Dictionary of Plant Names adds this fascinating (if true) footnote, that he died by hanging in South Africa, but Professor Len Newton has informed me that he died of natural causes. The genus Hallianthus in the Aizoaceae was published in 1983 by German botanist Heidrun Elsbeth Klara Osterwald Hartmann. Hall is also commemorated with Senecio hallianus and with the specific epithet hallii in about 30 current taxa. (CRC World Dictionary of Plant Names)

He is commemorated with Conophytum hammeri and the genus Hammeria in the Aizoaceae which was published in 1998 by South African botanist Priscilla M. Burgoyne. (Etymological Dictionary of Succulent Plant Names; Steven Hammer, pers. comm.)

hampdenii: according to a JSTOR specimen record, Hydrodea hampdenii was collected by someone named Hampden, but the Illustrated Handbook of Succulent Plants has reference to a Hobart-Hampden. The actual honoree is the Rev. Arthur Kennet Hobart-Hampden (1856-1932), the Vicar between 1910 and 1916 at St. Anne's Church, Bowden Hill, Chippenham, Cambridgeshire, England. Hydrodea hampdenii was described from living material sent to the British Museum by Rev. Hobart-Hampden in February, 1928. (David Hollombe, pers. comm.)

She conducted botanical field studies in Argentina, Mexico and the southwestern United States in addition to Africa. The genus Hartmanthus in the Aizoaceae was published in 1995 by American botanist Steven A. Hammer. (Hugh Clarke; JSTOR)

Hartogia/Hartogiella/hartogii: for Johannes (Jan, Johan) Hartog (Hartogius, Hartogh, Hertog) (1663-1722), German/Dutch (born Aachen) plant collector and gardener, worked in Sri Lanka and Cape Town, master-gardener and first official botanist for the Dutch East India Company's garden in Cape Town (fl. 1689) who collected indigenous seed while working under Simon van der Stel, first governor of the Cape. By orders from the Directors of the Dutch East India Company, plant material was sent to the Amsterdam Hortus Botanicus, but as the Hortus did not wish to maintain a herbarium, the specimens came into the possession of Nicolaas Laurens Burman, author of Flora Indica (1768) which had a 33-page supplement on Cape flora attached. Paintings of some twenty-four kinds of Proteas were made by Hartog or possibly by his collaborator Heinrich Bernhard Oldenland (1663-1697) and were sent to Holland where they were brought to the attention of Herman Boerhaave (1668-1738), Director of the Hortus Botanicus of the University at Leyden, who transformed the paintings into engravings and printed them in his catalogue of plants (1720). As for Hartog, he was an intrepid explorer who participated in an expedition to the then remote interior of Namaqualand, and was also in the area of Hermanus. Everywhere he went he collected seeds and plants. He fell into some kind of disgrace after the tenure of Van der Stel as governor of the Cape, spending time in 'Dutch' Ceylon, and he finally expired far from home in Surinam, South America. The genus Hartogia in the Celastraceae was published by Swedish botanist Carl Linnaeus the Younger in 1782 and Hartogiella also in the Celastraceae was published in 1983 by South African botanist Leslie Edward Wastell Codd. Johannes Hartog is also commemorated with the former taxon Mimetes hartogii, published by British botanist Robert Brown in 1810, and now synonymized to M. fimbriifolius.

The genus Hartwegia in the Liliaceae (formerly Anthericaceae) was published in 1831 by German botanist, physician and zoologist Christian Gottfried Daniel Nees von Esenbeck. Another genus Hartwegia, which is in the Orchidaceae, does not appear in Southern Africa, and is in fact not considered a valid taxon, was named for the son who worked at the Paris Jardin des Plantes and later at the London Horticultural Society where he was sent to Mexico in 1836 to collect seeds and plants for introduction into English Gardens and came to the attention of William Jackson Hooker, Director of the Royal Botanical Gardens at at Kew. (David Hollombe, pers. comm.)

Sonder of Hamburg of the first three volumes of Flora capensis from 1860-1865. He also produced The Genera of South African Plants (1838), which was the first significant botanical book to be published in Africa, the Manual of British Algae (1841), the Phycologia Britannica (1846-1851), and the Phycologia Australica (1858-1863). He collected along the Atlantic coast of the United States, Australia, Tasmania and the South Seas. He came to the Cape when he was 23 years old and stayed about four years before he returned to England. He was unquestionably one of the giants of South African botany. He is commemorated with the genus Harveya in the Scrophulariaceae which was published in 1837 by British botanist William Jackson Hooker, and in many taxa such as Albizia harveyi, Disa harveiana, Senecio harveianus, Ceratandra harveyana, Vitex harveyana, Gymnosporia harveyana, Sclerochiton harveyanus, Commiphora harveyi, Phylica harveyi and many others. (Gunn & Codd)

hassei: for Hermann Edward Hasse (1836-1915), noted American authority on lichens, author of The Lichen Flora of Southern California, another of the many figures in the world of botany who were medical doctors.

(JSTOR)

Haumaniastrum: for Lucien Leon Hauman (1880-1965), Belgian-born botanist who studied and collected plants in East Africa, but whose main experience was with South America. He arrived in Argentina in 1804 and was a professor at the newly established Faculty of Agronomy and Veterinary Medicine of the University of Buenos Aires until 1925. He collected plants in Argentina, Paraguay, Uruguay and Chile, and published many research papers. The Lucien Hauman Botanical Gardens of the University of Buenos Aires was named in his honor. The genus Haumaniastrum in the Lamiaceae was published in 1959 by Belgian botanists Paul Auguste Duvigneaud and Jacqueline Plancke. (CRC World Dictionary of Plant Names; Wikipedia)

havaasii: for Johan Jonsen Havaas (1864-1956), Norwegian lichenologist, botanist and farmer who studied the flora of western Norway.

Haworthia/haworthii: for Adrian Hardy Haworth (1768-1833), esteemed English entomologist, botanist, carcinologist and authority on succulents and Lepidoptera. He was the author of the authoritative Lepidoptera Britannica. He was a Fellow of the Linnean Society and a friend of Sir Joseph Banks. The genus Haworthia in the Aloaceae was published in his honor in 1809 by French botanist and physician Henri August Duval, and he is commemorated with Senecio haworthii and Lampranthus haworthii, and also probably for Ruschia haworthii and Tetragonia haworthii. (CRC World Dictionary of Plant Names; Wikipedia)

His older brother Joseph Harrison Haygarth was a schoolmaster in Lancashire, England. Walter Haygarth was adopted by J.M. Wood. He collected in Natal and East Griqualand, and contributed drawings to Wood's book of plants. He is commemorated with Chlorophytum haygarthii, Ceropegia haygarthii, Streptocarpus haygarthii and the former taxon Pavetta haegarthii, now synonymized to P. cooperi. Other taxa in southern Africa that probably honor him as well, that according to JSTOR records were either collected by him or by Wood, are Eriospermum haygarthii, Senecio haygarthii, Helichrysum haygarthii and Streptocarpus haygarthii. (Elsa Pooley; Gunn & Codd)

Hebenstretia: for Johann Christian Hebenstreit (Joannes Christianus Hebenstreitius) (1720-1791), a professor of medicine at Leipzig and also of botany and natural history at the Russian Academy of Sciences at St Petersburg. He was also personal physician to Count Kyrylo Rosumowskyj, the President of the Academy. The genus Hebenstretia in the Scrophulariaceae was published in 1753 by Swedish botanist Carl Linnaeus. I have no explanation for the inconsistency in spelling between Hebenstretia and Hebenstreit. (PlantzAfrica)

hedbergii: for Karl Olov Hedberg (1923-2007), Swedish botanist, taxonomist, author, professor of systematic botany at Uppsala University from 1970 to 1989. He was an authority on afro-alpine vegetation and did significant work with his botanist wife Inga in the mountains of East Africa, producing Features of Afroalpine Plant Ecology.

He is commemorated with Cladonia hedbergii. (Wikipedia)

Hedwigia: for Johann Hedwig (aka Johannes Hedwig or Joannis Hedwig) (1730-1799), German botanist, physician, and expert microscopist, sometimes referred to as the father of bryology because of his study of mosses. He was a professor of medicine and botany at the University of Leipzig, Director of the Leipzig Botanical Garden, author of Fundamentum Historiae Naturalis Muscorum Frondosorum in 2 vols. (1782-1783) and Species Muscorum Frondosorum (1801), and a Fellow of the Royal Society and foreign member of the Royal Swedish Academy of Sciences.

heeschii: the Harvard University Herbarium index of botanists lists a certain Heesch (fl. 1844) either from Sierra Leone or having collected there, but I'm not certain that this is the person whose name was honored by this epithet and I have no further information about him or her, except that David Hollombe sent me an excerpt in French that mentions a Théodore Heesch. The taxon in southern Africa that once had this specific epithet was Lycopodium heeschii, which has since been synonymized to Lycopodiella cernua, and which was published in 1861.

heidmannii: for Johann Christian Friedrich (Fritz) Heidmann (1834-1913), German missionary and botanical collector, visited by Swiss botanist Hans Schinz (1858-1941), with whom Heidmann agreed to collect and ship botanical specimens from German South-West Africa to Zurich. Schinz named Crotalaria heidmannii after him. Heidmann arrived in South Africa in 1865 to minister to the Basters, who were the descendents of Cape Colony Dutch men and indigenous African women, served his congregation for more than 40 years, and mediated peace talks between the Basters and Ovaherero in the Ovaherero Nama War. He died in a mental institution near Cape Town. (Wikipedia; JSTOR)

The genus was published in 1830 by Swiss botanist Augustin Pyramus de Candolle. (CRC World Dictionary of Plant Names)

heisteri/heisteria: for Lorenz Heister (1683-1758), German anatomist, surgeon and botanist, commemorated in Muraltia heisteria and the former taxon Tulbaghia heisteri, now synonymized to Agapanthus africanus. His botanical garden in Helmstädt was considered one of the most attractive in Germany. He studied anatomy and was an assistant physician in field hospitals at Brussels and Ghent, later earning his doctorate, acting as a field surgeon, and becoming a professor of anatomy and surgery. He was the author of a surgical work called Chirurgie and coined the term 'tracheotomy.' (Hugh Clarke, pers. comm.; Wikipedia)

helenae: for (1) Mrs. Ellen Sophie Bertelsen (fl. 1882), wife of a Norwegian missionary, E.A. Bertelsen (?-1883). She collected bryophytes in the Natal area, and is commemorated with Lejeunea helenae; (2) the taxon Ischyrolepis helenae (formerly Restio helenae) was published by British botanist and taxonomist Maxwell Tylden Masters and may be named for his wife Ellen Anne Ruck Tress (1836-1919), although this is by no means a certainty. (Gunn & Codd; David Hollombe, pers. comm.)

heleniae: for Mrs. Helena van Heerde (fl. 1937), wife of Pieter van Heerde of Springbok, Northern Cape. She was honored with the taxon Conophytum heleniae, which is now a synonym of C. tantillum ssp. heleniae. (Etymological Dictionary of Succulent Plant Names)

Hellmuthia: for Hellmuth Steudel, German physician and surgeon, the son of German botanist and physician Ernest Gottlieb von Steudel (1783-1856), the genus author. He was the author of Die medizinische Praxis, ihre illusionen und ihr Streben zur Gewissheit (Medical practice, their illusions and the quest for certainty, 1853) and Praktik der Heilgymnastik (Practice of physiotherapy, 1860), and the co-author of Der Nihilismus, Das Einzig Wahre in der Medizin (Nihilism, the One Truth in Medicine, 1887). The genus Hellmuthia in the Cyperaceae was published in 1850. ("The Floral Scales in Hellmuthia," by A. Vrijdaghs et. al., Annals of Botany, Vol. 98 [3], Sep. 2006; Hugh Clarke)

helmae: the taxon in southern Africa that once bore this specific epithet, according to the Plants of Southern Africa Checklist, is Lithops helmae, now synonymized to L. julii. This possibly commemorates the same Mrs. M. Helm as for helmiae.

helmei: for Nick A. Helme (fl. 1995), botanist and plant collecter, commemorated with Hesperantha helmei, Freylinia helmei, Metalasia helmei and Geissorhiza helmei, all of which he collected. (JSTOR)

helmutii: for Helmut Ernst Meyer (1908-1995), horticulturist at Stellenbosch University Botanic Garden, commemorated with Lithops helmutii and the former taxon Conophytum helmutii, which has now been reduced in rank to C. stephanii ssp. helmutii. (Etymological Dictionary of Succulent Plant Names)

hendersonii: there is a JSTOR specimen record of Plagiothecium hendersonii being collected by a D. Henderson in South Africa in 1917. The plant name author, Hugh Neville Dixon, received collections made by the Rev. James Henderson (1867-1930), Scottish educational missionary in South Africa and Principal at the Lovedale Institution, and by several members of his family including his son Donald, who collected the type specimen. Plagiothecium hendersonii has now been synonymized to Entodon macropodus. (David Hollombe, pers. comm.; Biographical Dictionary of Christian Missions by Gerald Anderson)

hendricksei: for Mr. S.J. Hendrickse of the farm 'Glenhart' near Caledon where the species Erica hendricksei was first found. The author, British-born South African botanist Hugh Arthur Baker, first saw the plant in a Cape Town florist shop. (David Hollombe, pers. comm.; Ted Oliver, pers. comm.)

Hennediella: for Roger Hennedy (1809-1877), Irish-born botanist of Scottish extraction from a family whose name originally was Kennedy. He started out as a block-cutter for a calico printing firm, then acquired the art of drawing on stone for the purpose of making textile designs. He became interested in botany as a source of designs and later began teaching courses in botany at the Athenæum at Glasgow and then at the Mechanics' Institute. He eventually was appointed a professor of botany at the Andersonian University at Glasgow in 1863, and occupied the chair there until his death. He drew up and published a manual for the use of his classes called The Clydesdale Flora: A Description of the Flowering Plants and Ferns of the Clyde District. The genus Hennediella in the Pottiaceae in 1896 by by French bryologist Jean Édouard Gabriele Narcisse Paris. He was also honored with the genus name Hennedya which was published by William Henry Harvey but that genus does nt appear in southern Africa. (Dictionary of National Biography; Hugh Clarke)

henningsii: for Paul Christoph Hennings (1841-1908), German mycologist and cryptogamist, amateur poet, author of Botanische Wanderungen, specialist in tropical fungi, worked in the botanical garden of Kiel, later curator of the botanical garden in Berlin, editor of Hedwigia durch die Umgebung Kiels, commemorated with Strychnos henningsii and a number of other taxa which do not appear in southern Africa. (Wikipedia)

He was also commemorated with the genus Henrardia which does not appear in southern Africa. (Etymological Dictionary of Grasses; CRC World Dictionary of Grasses)

Henricia: the original published name (1936) by L. Bolus for what was changed in 1938 to Neohenricia.

henriciae/henricii: for Dr. Marguerite Gertrude Anna Henrici (1892-1971), Swiss plant physiologist and plant collector. She began her career with the Division of Veterinary Services and was placed in charge of the Armoedsvlakte field station with particular responsibility to study the problem of lamsiekte or lame sickness, which was a botulism of phosphorus-deficient cattle. Later she transferred to the Division of Plant Industry under Dr. Pole Evans. She spent much of her life in the Orange Free State, obtaining a D.Sc. from the Univ. of South Africa for work on the content of Karoo shrubs and grasses, and the Division of Plant Industry built a well- equipped laboratory for her in Fauresmith for study of problems connected primarily with Karoo vegetation. She collected some 6000-7000 specimens mainly from western Orange Free State and Ermelo. She was also commemorated with the taxon Salsola henriciae, Lampranthus henricii and probably Ruschiella henricii.

henriquesiana/henriquesii: for Júlio Augusto Henriques (1838-1928), Portuguese botanist, founded a botanical museum and library at the University of Coimbra, renovated the botanical gardens where he became its 14th director, a position he held for 40 years, and made a major impact on the state of Portuguese botany. He began his education in law, receiving his baccalaureate degree in 1859, and at that time a degree course in law included subjects like chemistry, physics, mineralogy, zoology, botany and agriculture, which certainly influenced his already existing interest in scientific studies. In 1880 he founded the Broterian Society, the first botanical scientific society to be started in Portugal, in honor of Avelar Brotero, who had originally created the botanical garden at Coimbra. Taxa in southern Africa with these epithets include Buchnera henriquesii, Lecomptedoxa henriquesii and Inhambanella henriquesii, as well as the former taxon Baphia henriquesiana, now synonymized to Baphia massaiensis. (David Hollombe, pers. comm.; Biblioteca Digital de Botânica)

hensii: for (Jens) Frans Hens (1856-1928), who collected Campylopus hensii and other plants in the Congo. There was a Belgian artist named Frans Hens with these same dates who made a painting entitled Boulicoco, on the Congo River, so this very likely refers to the same person. He went to the Congo in 1888 and exhibited works depicting Africa in Brussels and Antwerp in1889 and 1890. Later he became a professor at the Institut National Superieur des Beaux Arts in Antwerp. (JSTOR)

hensseniae/henssenianum: for Aino Marjatta Henssen (1925-2011), prominent German botanist specializing in lichens and fungi, collected over 60,000 specimens for her herbarium, commemorated with Diploschistes hensseniae and probably Colchicum henssenianum. (Checklist of the Lichens of Australia)

Heppia: for Johann Adam Philipp Hepp (1797-1867), variously described as Swiss or German, a medical doctor, botanist and lichenologist. He was apparently born in Kaiserlautern, Germany, fled to Switzerland in 1849 as political refugee following the revolutionary uprising in the Bavarian Palatinate and Baden, and died at Frankfurt am Main. The genus Heppia in the Heppiaceae was published in 1854 by Italian lichenologist Abramo Bartolommeo Massalongo.

herbertii: for (1) Dr. Herbert Maughan-Brown (1883-1940), physician and plant collector in South Africa, Chief Medical Inspector of Schools of the Cape Province, lecturer in school hygiene at the University of Cape Town, commemorated with Phyllobolus herbertii and Sphalmanthus herbertii. His name is sometimes hyphenated and sometimes not. I don't know which is correct; (2) William Herbert (1778-1847), British botanist, botanical illustrator, poet, clergyman and member of Parliament, commemorated with the former taxon Wachendorfia herbertii (now W. paniculata). In southern Africa are also the taxa Aridaria herbertii and the former taxa Lithops herbertii (now L. gesineae), but given the commonness of the name 'Brown,' I hesitate to assign them to Dr. Herbert Brown. (Etymological Dictionary of Succulent Plant Names; S.A. Tydskrip Vir Geneeskunde, Obituary Mar. 1940; David Hollombe, pers. comm.)

Herbertus
: for Thomas Herbert (c.1656-1733), 8th Earl of Pembroke and 5th Earl of Montgomery, British politician during the reigns of William III and Anne, President of the Royal Society and a patron of the noted Italian botanist Pier Antonio Micheli. The genus Herbertus in the Herbertaceae was published by American botanist Asa Gray in 1821. (David Hollombe, pers. comm.; Wikipedia)

Hereroa: for the Herero people, Bantu speakers of southwestern Africa. The genus Hereroa in the Aizoaceae was published in 1927 by German botanists Moritz Kurt Dinter and Martin Heinrich Gustav Schwantes. (CRC World Dictionary of Plant Names)

hermani: Erica hermani, named for the locality of Hermanus, previously called Hermanuspietersfontein after a local landowner Hermanus Pieters. (Ted Oliver, pers. comm.)

Hermannia: for Paul Hermann (1646-1695), German-born Dutch botanist, herbalist, professor of botany at Leyden, traveller and explorer in Africa, India and Sri Lanka, plant collector at the Cape where he made one of the earliest plant collections now housed at the Sloane Herbarium, British Museum of Natural History, and at Oxford, in 1669 became professor of botany at Leyden and director of the Hortus Botanicus, Europe's finest botanical garden. The genus Hermannia in the Malvaceae was published by Swedish botanist Carl Linnaeus in 1753. (CRC World Dictionary of Plant Names)

hermannii: for (1) Ernst Hermann (fl. 1890), farmer and plant collector in the western coastal area of South-West Africa, murdered in the Herero War of 1904, commemorated with Stipagrostis (formerly Aristida) hermannii (Gunn & Codd); (2) Hermann Merxmüller (1920-1988), German botanist, professor of botany at the University of Munich, also Director of the Munich Botanical Gardens, conducted many expeditions to Africa, and discovered more than 100 new species of flowers, commemorated with Senecio hermannii. (David Hollombe, pers. comm.); (3) Paul Hermann (1646-1695), see entry for Hermannia, commemorated with the former Solanum hermannii, now synonymized to Solanum linnaeaum. There are also two former taxa, Mertensia hermannii (synonymized to Dicranopteris linearis) and Ornithogalum hermannii (synonymized to O. thyrsoides), but I don't know who they commemorate.

hermanniifolium: the taxon in southern Africa with this epithet is Pelargonium hermanniifolium with no information as to its derivation, except that it may relate to the previous entry.

Hermas: I can find no certain derivation for this generic epithet, which is usually said to be of unknown origin. W.P.U. Jackson with his penchant for suggesting names for puzzling genera has proposed that it might commemorate Hermas, the 1st or 2nd century author of the work called The Good Shepherd, a work treated with great authority in ancient times and ranked with the Holy Bible, but there is no evidence for this. This genus Hermas in the Apiaceae was published in 1771 by the Swedish botanist Carl Linnaeus.

Hermbstaedtia: for Sigismund Friedrich Hermbstaedt (1760-1833), German botanist, Prussian court apothecary in Berlin, professor of technological chemistry, author of many treatises, textbooks and works on chemistry, technology and agriculture. His Grundriss der Technologie (1814), was widely consulted by merchants, factory owners, and officials and as a member of the Technical Industrial and Trade Commission he performed a valuable service for Prussian industry. The genus Hermbstaedtia in the Amaranthaceae was published in 1828 by German botanist Heinrich Gottlieb Ludwig Reichenbach. (CRC World Dictionary of Plant Names; Antiquarian Booksellers' Association of America)

Herrea/herreana/Herreanthus/herreianus/herrei: for Adolar Gottlieb Julius (Hans) Herre (1895-1979), explorer, horticulturalist, curator of Stellenbosch University Botanical Garden, and succulent plant specialist who published a book on Mesembryanthemaceae in 1971. He collected over 300 species new to science and received the Fellow Award, the highest honor the Cactus and Succulent Society of America can confer in May, 1965. The genus Herrea in the Aizoaceae was published in 1927 by German botanist Martin Heinrich Gustav Schwantes and Herreanthus also in the Aizoaceae in 1928 by the same author. He is also honored with Avonia herreana, Senecio herreianus, and several dozen taxa with the specific epithet herrei, including Othonna, Lithops, Cheiridopsis, Brunsvigia, Moraea, Euphorbia, Ruschia, Cyrtanthus, Astroloba, Haworthia and others. (Etymological Dictionary of Succulent Plant Names)

Herschelia/Herschelianthe: for Sir John Frederick William Herschel (1792-1871), English astronomer who named the seven then-known moons of Saturn and the four then-known moons of Uranus. He was the son of the famous astronomer Sir William Herschel 1738-1822) who discovered the planet Uranus. "In 1833 Herschel travelled to South Africa in order to catalogue the stars, nebulae, and other objects of the southern skies. This was to be a completion as well as extension of the survey of the northern heavens undertaken initially by his father William Herschel. He arrived in Cape Town on 15 January 1834. Amongst his other observations during this time was that of the return of Comet Halley. However, in addition to his astronomical work, this voyage to a far corner of the British empire also gave Herschel an escape from the pressures under which he found himself in London, where he was one of the most sought-after of all British men of science. While in southern Africa, he engaged in a broad variety of scientific pursuits free from a sense of strong obligations to a larger scientific community. It was, he later recalled, probably the happiest time in his life." The genus Herschelia in the Orchidaceae was published in 1838 by British botanist John Lindley and Herschelianthe also in the Orchidaceae in 1983 by German botanist Stephan Rauschert. (from Wikipedia)

Hertia: for Joannes Casimirus (Johann Kasimir) Hertius (1679-1748), German physician. The genus Hertia in the Asteraceae was published in 1832 by German botanist Christian Friedrich Lessing. (CRC World Dictionary of Plant Names)

Hessea: either for (1) Paul Hesse, botanical traveller, or (2) Christian Henrich Friedrich Hesse (1772-1837), a Lutheran Luthern minister, scholar and naturalist who came to Cape Town from Hanover in 1800 and grew succulents, returning to Germany in 1817. He was familiar with and extended hospitality to many visiting and local naturalists. The website Amaryllidaceae.org says Hessea was dedicated to Paul Hesse, but Gunn & Codd say that it honors C.H.F. Hesse. Rudolf Marloth's book The Flora of South Africa (1915) says that Hessea is "Named after the Rev. Friedrich Hesse, a Lutheran minister, in whose hospitable house Burchell stayed while at Cape Town." The CRC World Dictionary of Plant Names states that the epithet commemorates Paul Hesse, while mentioning W.P.U. Jackson's opinion that it is for C.H.F. Hesse. The genus Hessea in the Amaryllidaceae was published in 1837 by British botanist William Herbert. (CRC World Dictionary of Plant Names)

hesseana: for Christian Henrich Friedrich Hesse (1772-1837), see above, commemorated with Erica hesseana. (Gunn & Codd; Ted Oliver, pers. comm.)

Heudelotia/heudelotii: for Jean P. Heudelot (1802-1837), French botanist and plant collector in tropical Africa (mainly Senegal and Gambia), compatriot of naturalist Ambroise Palisot Beauvois. Heudelot also collected fish which were sent from West Africa to Paris. He is commemorated with Bolbitis heudelotii and the former taxon Sesamum heudelotii, now synonymized to Ceratotheca sesamoides. He was honored as well by the genus Heudelotia in the Burseraceae, published in 1832 by French botanist and physician Achille Richard. (JSTOR)

heuglinii: for Theodor von Heuglin (1824-1876), German zoologist, ornthologist and explorer, consul at Khartoum. Although trained as a mining engineer, he quickly became interested in the natural sciences and was driven to the scientific exploration of little-known regions. He spent the period 1850-1864 in Northeast Africa, visiting Egypt, the Red Sea and the Sinai, Ethiopia and the Kordofan region of the Sudan, Abyssinia, Khartoum and the White Nile. 1870 and 1871 found him in Spitzbergen and Novaya Zemlya, but he returned to North-east Africa in 1875 and was planning an exploration of the Socotro archipelago in the Indian Ocean when he died. He was the author of Systematic Review of Northeastern-African Birds (1855), Travels in Northeast Africa, 1852-1853 (1857), Systematic Review of Mammals of Northeast Africa (1867), Ornithology of Northeast Africa (1869-1875), and other works. He is commemorated with the former Cycnium heuglinii, now C. tubulosum. (David Hollombe, pers. comm.; Wikipedia)

Hewittia: Gledhill says this is for a "Mr. Hewitt," editor of the Madras Journal of Literature and Science (1837), but others say for John Hewitt (1880-1961), British zoologist and naturalist, Director of the Sarawak Museum 1905-1908 and according to W.P.U. Jackson and the CRC World Dictionary of Plant Names Director of the Albany Museum at Grahamstown 1910-1958. This last obviously cannot be correct since the genus was published in 1837 by Scottish botanists Robert Wight and George Arnott Walker-Arnott. Hugh Clarke has found that the editor of the Madras Journal was J.C. Morris, but this is the publication in which Wight and Arnott published the genus Hewittia, and perhaps Mr. Hewitt was an editor, not the editor. The indefatigable Clarke has also provided the following given to him by Henry Noltie, the Edinburgh botanical historian who wrote Robert Wight's biography: "Possibly after Hewett Cottrell Watson (1804-1881), English phrenologist, botanist and evolutionary theorist, who, among many achievements, edited The London Catalogue of British Plants from 1844 to 1874. Robert Wight (1796-1872) met Watson after returning from India in 1831 and spent three years recovering from illness and before returning to India. In 1832, Wight met Hewett and they went botanising together in the Scottish Highlands. Wight often made spelling mistakes when naming flowers and it is possible that 'Hewittia' would then be a misspelling of 'Hewett.' The genus was first described in the Madras Journal of Literature and Science in 1837." Given the relationship between Wight and Hewett Watson, this seems like a very credible scenario. (Gledhill, The Names of Plants; Henry Noltie, pers. comm. to Hugh Clarke)

heyniae/heynii: there are some possibilities here and I lump these two names together because they may be named after the same or a different person. (1) Benjamin Heyne (1770-1819), for whom the genus Heynea was named, a Moravian-Scottish surgeon, naturalist, author and botanist in the service of the British East India Company who headed up the Lalbagh botanical garden at Bangalore, commemorated with Hedyotis heynii; or (2) Karel Heyne (1877-1947), Dutch botanist and author at Bogor, for whom the genus Heynella was named; or (3) Friedrich Adolf Heyne (1760-1826), German botanist and author. Neither Heynea or Heynella appear in southern Africa. All three of these men are included in the Harvard University Herbarium list of botanists and the IPNI list of plant authors. In addition to the former Hedyotis heynii, now synonymized to Oldenlandia herbacea, there also is in southern Africa the taxon that at one time bore this specific epithet, the former Alectra or Orobanche heyniae, now synonymized to Alectra orobanchoides. (David Hollombe, pers. comm)

Heywoodia: for Arthur William Heywood, who was Conservator of Forests in the Transkei region of South Africa and author of Cape Woods and Forests (1886). Hugh Clarke adds: "He fought an uphill battle to conserve the indigenous natural forests in the Transkei, such as the Dwesa-Cwebe forested area located in rugged Wild Coast of the Eastern Cape from rapid destruction by local inhabitants who chopped down forests for merchantable timber trees, and decimated the remaining young trees using them as poles or ‘wall’ material in the construction of huts and kraals leaving behind impoverished soil." The genus Heywoodia in the Euphorbiaceae was published in 1907 by Scottish-born South African botanist and bryologist Thomas Robertson Sim. (CRC World Dictionary of Plant Names; Hugh Clarke)

Hibbertia/hibbertii: for George Hibbert (1757-1837), eminent English merchant with the East India Company, politician and member of parliament, slave- and ship-owner, amateur botanist and book collector, created an extensive collection of Botany Bay and Cape plants, and funded various botanical expeditions. Hugh Clarke adds: "In 1781, he joined the family counting house Hibbert, Purrier and Horton involved in the shipping and distribution of slave-produced goods, particularly sugar from Jamaica. He became Chairman of the West India Dock Company; opposed William Wilberforce's proposal to abolish slavery on economic grounds, became an Alderman for the City of London (1798-1802), a Member of Parliament for Seaford (1806-1812), and Agent-General for Jamaica (1812-1831). He sponsored James Niven to collect plants in the Cape region of South Africa (1798-1803) and helped fund the National Lifeboat Institution (1824). He collected books, prints and art, and was a member the Linnean Society, the Royal Society and the Society of Antiquaries." The taxon in southern Africa with this specific epithet is Erica hibbertii, published by British botanist Henry Charles Andrews (fl. 1794-1830). He was also honored with the genus Hibbertia in the Dilleniaceae published in 1820 by British botanist Henry Charles Andrews. (Wikipedia; Ted Oliver, pers. comm.; Hugh Clarke)

Hiernia: for William Philip Hiern (1839-1925), British botanist and plant collector who worked at Kew and the British Museum, contributed to the Catalogue of the African plants collected by Dr. Friedrich Welwitsch in 1853-61, writing the section on dicotelydons, and was a Fellow of the Linnean and Royal Societies. The genus Hiernia in the Scrophulariaceae was published in 1880 by British botanist Spencer Le Marchant Moore. (CRC World Dictionary of Plant Names)

hieronymii: probably for Georg Hieronymus, editor of Hedwigia, in which Lycopodium hieronymii was published. (David Hollombe, pers. comm.)

hildebrandii: the taxon in southern Africa that once had this specific epithet is Blepharis hildebrandii, now synonymized to B. integrifolia. Johann Maria Hildebrandt's name has often been spelled as Hildebrand, such as in the 2nd edition of Botanical Exploration of Southern Africa by H.F. Glen and G. Germishuizen, so this is a possible derivation for this epithet. See following entry.

hildebrandtii: for Johannes (Johann) Maria Hildebrandt (1847-1881), German botanist and explorer who collected in East Africa, Madagascar, and the Comoro Islands during the period 1872-1881. He worked for the Berlin Botanical Garden and collected both botanical and zoological specimens. He was the first traveller to have collected in the area of Tsavo National Park and he made many collections in Kenya, Somalia and especially Madagascar. He died at the young age of 34 of a fever and bleeding stomach while on an expedition to Madagascar. Taxa in southern Africa that are either certainly or probably named for J.M. Hildebrandt include Cienfuegosia hildebrandtii, Pseuderanthemum hildebrandtii, Campylopus hildebrandtii, and the former Porothamnium hildebrandtii (now P. stipitatum), Tortula hildebrandtii (now Syntrichia fragilis), Buttonia hildebrandtii (now B. natalensis) and Boscia hildebrandtii (now B. mossambicensis). He was also honored with the genus Hildebrandtia, which does not appear in southern Africa. (Trees and Shrubs of Mpumalanga and Kruger National Park; Wikipedia)

hildenbrandii: for Franz Edler von Hildenbrand (1789-1849), doctor and professor, commemorated with Leptogium hildenbrandii. (David Hollombe, pers. comm.)

hillburttii: for Olive Mary Hilliard (1925- ) and Brian Laurence Burtt (1913-2008), distinguished South African botanists and taxonomists. According to an obituary, B.L. Burtt described 637 species new to science, more than half in the family Gesneriaceae! He was a giant in the field of plant taxonomy, collected almost 20,000 specimens in a lifetime of fieldwork, and is credited with an astonishing 260 solo-authored, 122 jointly-authored papers, and three major books: Streptocarpus: an African plant study, The Botany of the Southern Natal Drakensberg, and Dierama. He married Olive Hilliard in 2004. She worked at the National Herbarium, Division of Botany and Plant Pathology, was a lecturer in botany at Natal University, Pietermaritzburg, and then curator of the herbarium and research fellow. Taxa in southern Africa with this specific epithet are Encinella hillburttii and Erica hillburttii. (Gunn & Codd)

Hilleria: for Matthaeus Hiller (1646-1725), German botanist, professor of Oriental Languages and Theology at the University of Tübingen, author of Hierophyticon, sive commentarius in loca scripturae sacrae quæ plantarum faciunt mentionem distinctus in duas partes. The genus Hilleria in the Phytolaccaceae was published in 1829 by Brazilian botanist José Mariano da Conceição Vellozo. (CRC World Dictionary of Plant Names)

hillianum: very likely for Arthur William Hill (1875-1941), British botanist and taxonomist, Director of Kew Gardens, author of many works including The Genus Thesium in South Africa. The taxon in southern Africa which bears this specific epithet is Thesium hillianum.

Hilliardia/hilliardiae/Hilliardiella: for Olive Mary Hilliard (1925- ), South African botanist, specially interested in the flora of Natal, collected thousands of specimens and was a prodigious writer on plants, commemorated with Plectranthus hilliardiae, Schizoglossum hilliardiae and Cymbopappus hilliardiae. See also hillburttii. The genus Hilliardia in the Asteraceae was published in 1987 by Swedish botanist Rune Bertil Nordenstam, and Hilliardiella also in the Asteraceae which I presume was named for her as well was published in 1999 by American botanist and entomologist Harold Ernest Robinson. (Nordenstam, "Notes on South African Anthemideae", Opera Botanica 92)

hillii: for Leslie J. Hill (1908-2003), South African chartered accountant, businessman, philanthropist, and collector and grower of succulent plants, commemorated with Astridia hillii and the former Lithops hillii ( now L. geyeri) and Conophytum hillii (now C. uviforme), and possibly also Anacampseros hillii. (Etymological Dictionary of Succulent Plant Names)

hilmarii: for Hilmar Albert Lückhoff (1916-1994), South African botanist in the Department of Forestry and later Director of the Forest Research Institute, Pretoria, son of Dr. James Lückhoff and younger brother of Carl August Lückhoff, particularly interested in Lithops, commemorated with Tanquana hilmarii, Deilanthe hilmarii and probably Aloinopsis hilmarii. (Gunn & Codd)

hilsenbergii: for Carl (Karl) Theodor Hilsenberg (1802-1824), German naturalist, botanist and ornithologist, a trained gardener who botanized and collected with with Wenceslas Bojer and Franz Wilhelm Sieber in 1822 in Mauritius. He is commemorated with the former taxon Osmunda hilsenbergii, now synonymized to Osmunda regalis. (Filicaes Africanae by Maximilian Kuhn)

Hippia: either a title given to the Roman goddess Minerva and others, or the name of some unknown botanist, although the CRC World Dictionary of Plant Names says that it derives from the Greek hippos, "horse," and refers to Hippias of Elis, a Greek philosopher and mathematician. Swedish botanist Carl Linnaeus first published the genus Hippia in the Asteraceae in 1771. (W.P.U. Taylor)

Hippocratea: for Hippocrates of Kos (Cos) (c. 460-370 BC), Greek physician, contemporary of Herodotus, Thucydides, Socrates and Plato, father of western medicine, pharmaceutical botanist, and founder of the Hippocratic School of Medicine and the Hippocratic Oath. He is generally credited with being the first person to believe that diseases were not caused by superstition or the gods, but little is actually known of his teachings because the body of works associated with him, called the Corpus, were of various ages and various authorships. The genus Hippocratea in the Celastraceae was published in 1753 by Swedish botanist Carl Linnaeus. (Elsa Pooley; CRC World Dictionary of Plant Names)

Hirschfeldia: for Christian Caius (Cay or Cayus) Lorenz Hirschfeld (1742-1792), German horticulturist, author of Anmerkungen über die Landhäuser und die Gartenkunst (Notes on country-houses and garden design,1773) and Theorie der Gartenkunst (Theory of garden-design, 1775) and the major 5-volume Theory of Garden Art. The genus Hirschfeldia in the Brassicaceae was published in 1794 by German botanist Conrad Moench. (CRC World Dictionary of Plant Names)

hislopii: for Alexander Hislop (c.1880-1945), British gardener at Kew Gardens, Assistant Superintendent at the Municipal Gardens, Oudtshoorn, South Africa (1902), Curator of the Pietermaritzburg Botanical Society’s gardens (1904–6), Curator of the Agricultural Department, S. Nigeria (1908). He collected plants in Rhodesia and died there in 1945. He is commemorated with the former Sida hislopii, now synonymized to S. pseudocordifolia. (Kew Bull., 1908, 376; J. Kew Guild, 1945, 464–65.)

hitchcockii: for Albert Spear Hitchcock (1865-1935), American agrostologist, commemorated with the former Tristachya hitchcockii, now T. lualabaensis. He graduated from Iowa State Agricultural and was appointed as a chemistry instructor at Iowa State University at the age of 21 but left after just three years to become the librarian and cuarator of the herbarium at the Missouri Botanical Garden and instructor at the Engelmann School of Botany at Washington University. In 1892 he became professor of botany at Kansas State Agricultural College where he extensively researched grass genera, and in 1901 he was appointed Chief of the Division of Agrostology at the United States Department of Agriculture, taking charge over the newly created Grass Herbarium in 1905. He was the author of A Textbook of Grasses (1914), The Genera of Grasses of the United States (1920), Manual of the Grasses of the United States (1935) and Manual of the Grasses of the West Indies (1936) among others. Beside his extensive work in the United States, he collected in Japan, China, the Phillipines, Vietnam, Kenya, Tanzania, South Africa, Zimbabwe, Guatemala, Panama, Nicaragua, Mexico, Bolivia, Columbia, Ecuador, Cuba, Jamaica and the Bahamas. He was also honored with the genus Hitchcockella, which does not appear in southern Africa. (Etymological Dictionary of Grasses; JSTOR)

Hoarea: for Sir Richard Colt Hoare (1758-1838). Hugh Clarke provides the following: "...English baronet, antiquarian, archaeologist, artist and traveller. He inherited a large estate from his grandfather, Henry Hoare, which enable him to pursue his interests in archaeological studies and travel. He visited Europe in 1785 and 1788 as described in his Recollections Abroad (1815) and A Classical Tour through Italy and Sicily (1819) and later Wales and Ireland. He worked on the first recorded excavations at Stonehenge (with William Cunnington) in 1798 [and] 1810, and excavated 379 burial sites on Salisbury Plain. His two-volume The Ancient History of Wiltshire (1812, 1821) outlined his findings . He became a Fellow of the Royal Society (1792) and the Society of Antiquaries of London." The genus Hoarea in the Geraniaceae was published in 1820 by British botanist Robert Sweet.

hochstetteri/hochstetteriana: for Christian Ferdinand Friedrich Hochstetter (1787-1860), German botanist, plant collector and Protestant minister, co-author with Ernst Gottlieb von Steudel of Enumeratio plantarum Germaniae Helvetiaeque indigenarum, a work on the flora of Germany and Switzerland, and co-author with Moritz August Seubert of Flora Azorica, a treatise on the flora of the Azores based on his voyage there in 1838. He was also honored with the genus Hochstetteria, published in 1838 by Swiss botanist Augustin Pyramus de Candolle. He was the father with his fourth wife of Christian Gottlieb Ferdinand von Hochstetter (1829-1884), geologist, anthropologist and plant collector at the Cape, Professor of Minerology and Geology at the Polytechnic Institute at Vienna, appointed by Emperor Franz Joseph as Director of the Natural History Museum, and geologist on board a round-the-world voyage of the frigate Novara which stopped at the Cape in December, 1857. He also had a son with his second wife, Karl (Carl) Christian Friedrich Hochstetter (1818-1880), who was a plant collector in Europe and the Azores, and who contributed to Flora Azorica. Taxa in southern Africa that bear these specific epithets include Ipomoea hochstetteri, Impatiens hochstetteri, Senecio hochstetteri, Indigofera hochstetteri, Stipagrostis hochstetteriana and several others that have been lost to synonymy. (Elsa Pooley; Wikipedia; Gunn & Codd)

hockii: for Adrien Hock (fl. 1911-1912), plant collector in the Congo. He collected Trichodesma hockii (now T. ambacense), Aneilema hockii and Gladiolus hockii (now G. dalenii), and may also be commemorated with Brachystegia hockii (now B. spiciformis). (JSTOR; Flora of Zimbabwe)

hoehnelii: although it seemed to me likely that the taxa in southern Africa that bear this specific epithet (the bryophyte species Pterobryopsis hoehnelii and Porella hoehnelii) were named to honor Franz Xaver Rudolf von Höhnel (Hoehnel) (1852-1920), an Austrian bryologist, mycologist and algologist, and professor of botany at Vienna University of Technology who described roughly 250 new genera and 500 species of fungi, David Hollombe has provided convincing evidence from the original publication (Hepaticae africanae by German bryologist Franz Stephani) that they actually commemorates Ludwig von Höhnel (1857-1942), Austrian naval officer, explorer and geographer. Von Höhnel was second-in-command of Count Sámuel Teleki Von Szek's expedition to Northern Kenya in 1887-1888 and acted as the expedition's cartographer and diarist. They were the first to survey a large part of the Great Rift Valley of East Africa, and they renamed Lake Turkana, which they were the first Europeans to see, as Lake Rudolf, after the patron of the expedition Crown Prince Rudolf of Austria. They made many significant observations about the climate, flora and fauna of the area and collected many ethnographic specimens. In 1892 von Höhnel explored the area around Mt. Kilimanjaro. Later he became Emperor Franz Josef's aide-de-camp and made a trip to Australia and Polynesia as the captain of the Austro-Hungarian cruiser Panther. He rose to the rank of Admiral. He was the youngest son of a civil servant and it seems possible to me that the above-mentioned Franz Xaver Rudolf von Höhnel may have been his older brother, but I haven't been able to confirm that. (David Hollombe, pers. comm.)

hoepfneri: for Carl (Karl) Höpfner (Hoepfner) (1857-1900), German-born geologist and electrochemical engineer who was mainly involved in techniques for the manufacture and extraction of minerals. He pioneered the cyanide method for extracting gold, established in 1899 the Hoepfner Refining Company in Hamilton, Canada, and was a plant collector, having several taxa named for him. He prospected in Angola and Hereroland (part of present-day Namibia) in 1883 and then in 1884-1885 in central South-West Africa with August Lüderitz. He is commemorated with Selago hoepfneri and the former Sida hoepfneri (now S. ovata), and probably for Hemizygia hoepfneri. (Gunn & Codd)

hoerleiniana/hoerleinianus: for Johannes Hörlein (Hoerlein) (fl. 1923), Director of Consolidated Diamond Mines (CDM) in Lüderitzbucht, who assisted German botanist and explorer Moritz Kurt Dinter with his botanical expedition to the southern Namib in 1922. He is commemorated with Lampranthus hoerleinianus. Justicia hoerleiniana (now synonymized to J. cuneata) and Cotyledon hoerleiniana (now synonymized to Tylecodon schaeferianus) were both published by Dinter, so they may have been named for the same individual. (Etymological Dictionary of Succulent Plant Names; PlantzAfrica)

Hoffmannia: for Georg Franz Hoffmann (1760-1826), German botanist and lichenologist. Hugh Clarke provides the following additional information: "He studied at the University of Erlangen (1786) where he became a professor of botany (1787-1792). Subsequently, he became head of the botany department and Director of the Botanical Gardens, both at Göttingen University (1792-1803) and at the University of Moscow (from 1804). He published several important treatises on the taxonomy of lichens, the first German flora (Deutschlands Flora, 1794), a classic monograph on the Apiaceae family (Genera Plantarum Umbelliferarum, 1814, 1816), and described the 3,528 species at the Moscow State University Botanical Garden (Enumeratio Plantarum et seminum hort botanici mosquensis, 1808). He also collected a large herbarium for the university." The genus Hoffmannia in the Rubiaceae was published in 1788 by Swedish botanist and taxonomist Olof (Peter) Swartz.

hoffmanniana: the taxon in southern Africa with this specific epithet is Disparago hoffmanniana with no definite information as to derivation. It was collected by Friedrich Richard Rudolf Schlecter in South Africa in 1896.

Hoffmannseggia/hoffmannseggiana/hoffmannseggianum: for Johann Centurius, Count Von Hoffmansegg (1766-1849), German botanist, entomologist, ornithologist, a traveller and co-author of a flora of Portugal entitled Flore portugaise. He is commemorated with Acanthopsis hoffmannseggiana (formerly Acanthodium hoffmannseggianum). The genus Hoffmannseggia in the Fabaceae was published by Spanish botanist Antonio José Cavanilles in 1798. (CRC World Dictionary of Plant Names)

hofmeyeriana: the former taxon Crassula hofmeyeriana, published in 1923 by German botanist Moritz Kurt Dinter, has been synonymized to C. ausensis. It would seem that the name was intended to honor a Mr. Hofmeyer who was in office as Administrator of South-West Africa when Dinter was collecting there, but this is only a supposition. The type of Crassula ausensis was collected in Namibia. (International Crassulaceae Network; JSTOR)

hollandii: for (1) for Frederick Huntly Holland (1873-1955), South African businessman and philanthropist. His passions were birds and plants, and he frequently sent interesting plants to Kirstenbosch for cultivation, often in response to special requests from the Curator of the Gardens, totalling more than 4,000 specimens, including a number of new species. He collected Senecio hollandii, Delosperma hollandii, Gladiolus hollandii and the former Agapanthus hollandii (now A. inapertus) and Pelargonium hollandii (now P. pulverulenta), and can be presumed to have been honored by these names. There are also taxa named Lampranthus hollandii and Thesium hollandii, and they may be named for him as well (JSTOR); (2) for a B. Holland, who collected the taxon Asplenium hollandii near Umtali in Rhodesia in 1904. Ferns of South Africa by Thomas Robertson Sim records Mrs. Bennett Holland as the collector, with no further information. (The Ferns of South Africa; JSTOR)

hollisii: for Alfred Claud Hollis (1874-1961), British administrator who served as British Resident to the Sultan of Zanzibar 1923-1929 and Governor of Trinidad and Tobago 1930-1936 and was the author of a historical account of Spanish Trinidad. He spent much time in East Africa and published The Masai: Their Language and Folklore in 1905 and The Nandi: Their Language and Folklore in 1909. He is commemorated with the former taxon Commiphora hollisii, now synonymized to C. schimperi. (David Hollombe, pers. comm.; Wikipedia)

hollowayana: for Henry Mitchell Holloway (1904-?), South African horticulturist who collected Ruschia hollowayana (now synonymized to Eberlanzia schneideriana) in 1837 in Namibia. He worked at Kew Gardens and then was in charge of the government gardens in Windhoek, Namibia, 1937-1938 and again 1938-1967. Later he was Assistant Director of Parks in Pretoria. (Gunn & Codd)

Holmskioldia: for Johan Theodor Holm (Holmskjold) (1732-1794), Danish botanist and physician. He graduateds from the University of Copenhagen in 1760 and became a professor in medicine and natural history at Sorø Academy in 1762. He also founded a botanical garden there. From this point he became more interested in botanical and administrative matters. He was director general of the Danish Postal Services in Copenhagen from 1767 until his death. He was also cabinet secretary for Queen Juliana Maria, consort of King Christian VII, first Director-in-chief of the Royal Danish Porcelain Factory, and one of two directors for a new botanical garden at Charlottenborg, the other one being Christen Friis Rottbøll. He was the author of a celebrated two-volume work on fungi called Beata ruris otia fungis Danicis Impensa ("Happy Resting Periods in the Country Studying Danish Fungi"). He was a member of the Royal Danish Academy of Sciences and Letters. His reputation was considerably tarnished when it was revealed later that he had been guilty of embezzlement against both the Queen, the Postal Services and the Royal Porcelain Factory. The genus Holmskioldia in the Lamiaceae was published in 1791 by Swedish chemist, botanist and entomologist Anders Jahan Reitzius. (CRC World Dictionary of Plant Names)

holstii/holstiana: for Carl Hugo Ehrenfried Wilhelm Holst (1865-1892), prolific German-born plant collector in Tanzania and gardener at Mialo Mission Station. He is commemorated with taxa such as Rhynchostegiella holstii, Ochna holstii and Radula holstiana, plus a number of other taxa in genera Cordia, Mystroxylon, Jasminum, Strychnos, Habenaria and Gnidia that have been lost to synonymy. (Etymological Dictionary of Grasses)

holtii: for W.E. Holt (fl. 1932), who collected Erica holtii in eastern Transvaal. (Gunn & Codd)

holtzii: for Wilhelm Holtz (fl. 1901-1912), plant collector in tropical Africa, commemorated with the former Celtis holtzii (now C. africana) and Diospyros holtzii (now D. mespiliformis), and probably the former Ekebergia holtzii (now E. capensis). (Contributions to the biosystematics of Celtis L. by Ali Sattarian; JSTOR)

Holubia/holubii: for Dr. Emil Holub (1847-1902), Czech author, physician, cartographer, naturalist and traveller/explorer in southern Africa who made several expeditions in Southern Africa as far as Victoria Falls (which he mapped); but failed in his ambition to traverse from the Cape to Cairo, as illness and hostile tribes in Zambia forced him to retreat. He was the author of Seven Years in Africa (1880) as well as the first account of Victoria Falls in English. He is commemorated with a number of taxa including Barleria holubii, Indigofera holubii, Cullen holubii, Echinochloa holubii, Ipomoea holubii, Eulophia holubii and Senecio holubii. The genus Holubia in the Pedaliaceae was published in 1884 by British botanist Daniel Oliver. There is also a genus Holubia in the Gentianaceae family named for the same individual, but it is not present in southern Africa. (Wikipedia; CRC World Dictionary of Plant Names)

homblei: for Henri Antoine Homblé (1883-1921), Belgian botanist and prolific botanical collector in tropical Africa, especially the Congo. Taxa in southern Africa that bear this specific epithet include Fadogia homblei, Indigofera homblei and the former Moraea homblei (now M. carsonii) and Acalypha homblei (now A. ambigua). (Etymological Dictionary of Grasses)

Hoodia: for a "Mr. Hood, a cultivator of succulent plants" according to the author Robert Sweet who published the name in 1830. David Hollombe adds this: "There are many references in journals of the time to "Mr. Hood, Surgeon, South Lambeth, who possesses a fine collection of rare succulent plants, which he cultivates with great success." This may be Dr. William Chamberlain Hood (1790-1879), British surgeon who lived in South Lambeth, London, and collected succulents. Many other sources like PlantzAfrica repeat the same information that the name honors succulent grower Mr. Van Hood, which may in fact refer to the same person. Hugh Clarke adds that South Lambeth and Chelsea, where Sweet lived, are both in central London so they may have met there, and they were approximately the same age. The genus Hoodia in the Asclepiadaceae and was formerly known as Stapelia. (CRC World Dictionary of Plant Names; Etymological Dictionary of Succulent Plant Names; PlantzAfrica; Hugh Clarke)

hookeri/hookeriana/hookerianum/hookerianus/Hookeriopsis: for (1) Sir Joseph Dalton Hooker (1817-1911), great British botanist and explorer. He was a close friend of Charles Darwin, a plant collector at the Cape (briefly), and Director of Kew Gardens for 20 years. He was a paleobotanist on the Geological Survey of Great Britain in 1846, collected plants for Kew in India, sailed on HMS Erebus on the 1839-1843 voyage to the Antarctic which resulted in Flora Antarctica: Botany of the Antarctic Voyage, Flora Novae-Zelandiae (1851–53) and Flora Tasmaniae (1853–59). It was during this voyage that he was briefly at the Cape. From 1847 to 1851 he was in the Himalayas, an expedition that resulted in his Himalayan Journals and Flora Indica. In 1860 he ventured to Palestine and in 1871 to Morocco. Then in 1877 he visited the western United States with the famous American botanist Asa Gray. Undoubtedly his magnus opus was the 7-volume Flora of British India. He was the son of W.J. Hooker and father of botanical illustrator Harriet Anne Hooker who was married to botanist William Turner Thiselton-Dyer. J.D. Hooker is commemorated with Trochomeria hookeri, Lithops hookeri, Agathosma hookeri and the former taxa Cucumis hookeri (now C. africanus) and Senecio hookerianus (now Kleinia fulgens), and probably for Chondropetalum hookerianum. He is further remembered with the genus Hookerella which does not appear in southern Africa; (2) Sir William Jackson Hooker (1785-1865), father of J.D. Hooker, professor of botany at Glasgow University, close friend of Sir Joseph Banks and first Director of Kew Gardens. His first botanical trip was to Iceland in 1809 which was successful except for almost dying in a fire which destroyed his samples. In 1814 he went to France, Switzerland and northern Italy. He was the author of Tour in Iceland (1809), Muscologia (1818), Musci exotici (2 vols., 1818-1820), Flora Scotica (1821), British Flora (1830), British Flora Cryptogamia (1833), and many other books including various works on the botanical expeditions of Sir William Edward Parry, Sir John Franklin and Frederick William Beechey. He helped to establish the Royal Botanic Institution of Glasgow and to lay out and develop the Glasgow Botanic Gardens. He is commemorated with Dracaena hookeriana, Hypericum hookerianum and the former taxon Barbula hookeri, now synonymized to B. calycina.The genus Hookeriopsis in the Hookeriaceae was published in 1877 by Swiss bryologist August Jaeger, and its name means "like Hookeria," which was a genus of bryophytes named in 1808 in honor of William Jackson Hooker by British botanist James Edward Smith. (Wikipedia; Hugh Clarke, pers. comm.)

hooleae: there is a JSTOR record of Faucaria hooleae being collected in South Africa with no date by a G. Britten (probably South African botanist Grace Violet Britten) and another person named Hoole with no initials. The taxon was published in 1934 by Louisa Bolus. As far as I know, this is the only taxon which has this specific epithet.

hoolei: the only clues I have about this specific epithet which is attached to genus Viscum is a collection record indicating that it was collected by a T.T. Hoole and a Delbert Wiens near Grahamstown in 1976. This is the single taxon which bears this epithet.

hopkinsii: probably for John Collier Frederick Hopkins (1898-?, fl. 1931), British botanist and plant collector in Zimbabwe, author of Tobacco Diseases, with Special Reference to Africa, a specialist on fungi and lichens, Director of the International Mycological Institute 1956-1964. Brachystegia hopkinsii (now synonymized to B. boehmii) was collected by a G. Dehn (probably Mrs. Gertrude Dehn, described as a a collector of plants in the Marondera and Rusape areas of Zimbabwe) first in 1941 and again in 1952. Another Hopkins listed on the JSTOR list of plant collectors is the British entomologist George Henry Evans Hopkins, born in 1899, who just might have been a brother of J.C.F. Hopkins, although I have not been able to establish that. He collected in Nigeria and worked for the London School of Tropical Medicine.

hornbyi: for Henry Epton Hornby (1890-1976), a collector of Grewia hornbyi (in Mozambique) and author of "A Contribution to the Study of the Vegetation of Mpwapwa," covering the area within 20 miles of the Mpwapwa Veterinary Research Station in Tanzania. His wife Robina McEwan Hornby (c.1893-?, fl. 1947-1948) is listed on the JSTOR list of plant collectors and may have worked with him. H.E. Hornby also collected Merremia hornbyi, which does not appear in southern Africa, in Tanzania in 1938. Another listed Hornby is A.J. Ward Hornby, born in 1893, algologist, plant name author and plant collector in Mozambique, who may have been a brother of Henry. Incidentally JSTOR records list his name variously as H.E. Hornby and H.I.E. Hornby.

hornschuchiana: for Christian Friedrich Hornschuch (1793-1850), German botanist, student of bryophytes, associate professor then full professor of natural history and botany, and director of the botanical gardens at the University of Greifswald, co-author of Bryologia Germanica (1823-1831), commemorated with the former taxon Barbula hornschuchiana, now synonymized to Pseudocrossidium hornschuchianum. Beginning as an apprentice pharmacist, he became an assistant to alpine flora specialist David Heinrich Hoppe, and then later worked as an assistant to bryologist and cofounder of the Regensburg Botanical Society Heinrich Christian Funck. He studied with Carl Adolph Agardh and was appointed as an associate professor (later full professor) of natural history and botany at the University of Greifswald and director of the botanical gardens there. He was also co-author with Christian Gottfried Daniel Nees von Esenbeck of Bryologia Germanica (1823-1831). (Wikipedia)

horsfallii: for Mr. Thomas Berry Horsfall (1805-1878) (often recorded as J.B. rather than T.B.), nineteenth century British politician who caused the type material of Eulophia horsfallii, collected in West Africa, to be cultivated and flowered in his glasshouse in England, which was beautifully illustrated in Curtis's Botanical Magazine in 1865. He was a Member of Parliament for Liverpool, the first President of the Liverpool Chamber of Commerce, and Lord Mayor of Liverpool from 1847-1848. He was also for a time Head of the Liverpool Architectural and Archaeological Society. The PlantzAfrica webpage for Eulophia horsfallii contains the following quote, received by SANBI in 2011, from from Mr. Peter Morrall: "My great grandfather, George Morrall, head gardener and estate bailiff to Thomas Berry Horsfall, was the first to cultivate a species of orchid new to England, when Mr. Horsfall was sent a plant specimen from Mr. S. Cheetham, Calabar River, Nigeria, in 1861. Thomas Berry Horsfall was a Member of Parliament and a shipping merchant working out of Liverpool. The orchid flowered in the glasshouses at Bellamour, Colton, Staffordshire, in 1864, and was subsequently registered in London by George Morrall, with the  name ‘Lisochillus Horsfallii'. The species was reported lost to cultivation until March 1906, when Mr. Walter Rothschild, of Tring Park, Hertfordshire, received a silver gilt Flora Medal from the Orchid Committee of the Royal Horticultural Society." Interestingly, despite this communication, the PlantzAfrica webpage in a previous paragraph gives the derivation of the name to J.B. Horsfall. The error in naming seems well established, in Curtis's Botanical Magazine, Vol. 91 (1865) by Sir William Jackson Hooker et. al., JSTOR, and many other references, so perhaps for some reason he went by the initials J.B. and this may not have been an actual error. (PlantzAfrica; Wikipedia; David Hollombe, pers. comm.)

hortenseae: for Hortense Jeanne Slabbert (née Muir) (1908-1985), daughter of Scottish physician and naturalist Dr. John Muir (1874-1947) and Susanna Muir (née Steyn) (1882-1970). She is commemorated with the taxon Muiria hortenseae, formerly Gibbaeum hortenseae. See also susannae and Muiria. (Etymological Dictionary of Succulent Plant Names)

Hoslundia: for Ole Haaslund Schmidt (d. 1802), Danish botanist and naturalist, traveller and plant collector in Ghana with Danish physician and botanist Peter Thonning. The genus Hoslundia in the Lamiaceae was published in 1805 by Danish-Norwegian botanist and zoologist Martin Henrichsen Vahl. The generic epithet Haaslundia is a synonym. (CRC World Dictionary of Plant Names; JSTOR)

Hottonia: for Petrus Houttuyn (Pieter Hotton) (1648-1709), Dutch botanist and physician, professor of botany at Leyden University and supervisor of the university’s botanical garden, and member of the Royal Society of London. The genus Hottonia in the Primulaceae was published in 1753 by Swedish botanist Carl Linnaeus. (CRC World Dictionary of Plant Names)

howardiana: possibly for Charles Walter Howard (1882-1928), studied at Cornell University, went to South Africa as an entomologist under the auspices of the British government, and then became an entomologist in the Department of Agriculture of Lourenzo Marques, Portuguese East Africa, author of A List of the Ticks of South Africa (1908) and Sericulture Industry of South China (1923), about silkworms. The taxon in southern Africa with this specific epithet is the former Ficus howardiana, now synonymized to F. stuhlmannii. Of all the Howards on the JSTOR list of collectors for Africa, Charles Walter Howard is the only one whose dates can correspond with the 1908 collection date and the 1909 publication date. There is a photographic record online of a gravestone with his name and dates on it from a cemetary at Ogdensburgh, New York. (David Hollombe, pers. comm.)

Hoya: for Thomas Hoy (c.1750-1822), English botanist and gardener to the Duke of Northumberland. Hugh Clarke adds the following: "He became a Fellow of the Linnean Society in 1788 and presented a number of flowering plants to the society from which several species were first formally described including the Australian plants Acacia suaveolens, Acacia myrtifolia and Goodenia ovata. [Scottish botanist] Robert Brown (1773-1858) named the plant genus in his honour describing Hoy as someone 'whose merits as an intelligent and successful cultivator have been long known to the botanists of this country.'" The genus Hoya in the Asclepiadaceae was published in 1810. (Hugh Clarke)

hubbardiana: for Dr. Charles Edward Hubbard (1900-1980), British botanist and agrostologist, author of Grasses: a Guide to their Structure, Identification, Uses and Distribution in the British Isles, Keeper of the Herbarium and Library at Kew and later Deputy Director, son of Charles Edward Hubbard who was head gardener to the Queen of Norway, commemorated with Aristida hubbardiana. He also collected about 15,000 specimens during a fairly short stay in Australia. (Etymological Dictionary of Grasses; Wikipedia)

Huea: for Abbé Auguste-Marie Hue (1840-1917), French botanist and lichen specialist, author of Lichens De Canisy Et Des Environs, studied the lichens collected on the French Antarctic expeditions of 1904-1907 and 1908-1910. The genus Huea in the Teloschistaceae was published in 1938 by American lichenologists Carroll William Dodge and Gladys Elizabeth Baker. Thanks to Dr. Shaun Russell of Bangor University, Wales, for confirming this derivation.

Huernia/Huerniopsis: for Justus Heurnius (1587-1652), Dutch missionary, doctor and and an early collector at the Cape, S.Africa. His drawings constituted the iconotypes for Stapelia which is what the first taxa of Huernias were described as. He was the author of De Legatione Evangelica ad Indos capessenda admonitio (1618), and discovered Orbea variegata at the Cape in April 1624 while on his way to Batavia (present-day Jakarta) as a missionary. In 1639 he returned to the Netherlands where he became a minister at Wijk bij Duurstede and helped to translate the Bible into Malay The genus name Huernia in the Asclepiadaceae was misspelled by Robert Brown who published it in 1810. Huerniopsis (which means 'resembling Huernia' and which strictly speaking is not named in honor or Justus Heurnius, also in the Asclepiadaceae) was published in 1878 by Nicholas Edward Brown. (Elsa Pooley; Biographical Dictionary of Christian Missions; CRC World Dictionary of Plant Names)

Hugonia: probably for Augustus Johannes Hugo (?-1753), wrote his dissertation for a Doctor of Medicine degree at the University of Leyden, Dissertatio botanica inauguralis de variis plantarum methodis (1711), published by Abraham Elzevier. His advisor on this dissertation was Herman Boerhaave. He travelled in Switzerland in 1732 with Swiss botanist and physician Albrecht von Haller. One piece of evidence for this derivation is that the name Hugonia (in the Linaceae) was published by Linnaeus in 1753 which was the very year that Augustus Johannes Hugo died. A less likely possibility would be his son, Augustus Ludovicus de Hugo (August Ludwig von Hugo) (1722- ), co-author with Albrecht von Haller of Dissertatio anatomico-medica inauguralis de glandulis in genere, et speciatim de thymo (1746) who received his doctorate in medicine in that year. He sent Haller what was described as 'Hercynian plants and Malabar grasses.' And a third even less likely possibility is that the name refers to English botanical author John Hugon who published a dissertation on the systems of botany in 1771, and Paxton's Botanical Dictionary and other sources make this claim (possibly all just quoting a single incorrect source), but it is most likely that A.J. Hugo is the honoree here. The 1866 work Verba Nominalia by Richard Stephen Charnock says the derivation is for A.J. Hugo. (CRC World Dictionary of Plant Names; Trees and Shrubs of Mpumalanga and Kruger National Park; Boerhaave and His Time by Gerrit Arie Lindeboom)

He was the Director from 1931 to 1958 of the Laboratoire de Phanérogamie of the Natural History Museum, Paris. He undertook 10 expeditions to Madagascar and also travelled to the Andes, north and east Africa, and the Congo. He was in South Africa from 1933-1934, collecting mainly at the Cape and in Natal. He began the Flore de Madagascar et des Comores, and was the author of several other works on Madagascar flora. He had several genera named after him including Humbertiella, Humbertina, Humbertiochloa, Humbertacalia, Humbertia, Humbertianthus, Humbertioturraea and Humbertiodendron, none of which appear in southern Africa. (JSTOR; Gunn & Codd)

Humea: for Lady Amelia Hume (née Egerton) (1751-1809), an English amateur botanist. The genus Humea in the Asteraceae was published in 1804 by British botanist James Edward Smith. (CRC World Dictionary of Plant Names; A Biographical Index of British and Irish Botanists)

hutchinsii: for Sir David Ernest Hutchins (1850-1920), British forestry expert who worked for ten years in the Imperial Forestry Service in India then 23 years in the South African Forest Service, and a final three years in the British East Africa Forest Service. After his retirement he toured in and reported on the forests of Cypress, Australia and New Zealand. He is commemorated with Brachylaena hutchinsii which is now B. huillensis, and Salix hutchinsii. (Gunn & Codd)

hutchinsoniana/hutchinsonii: for Dr. John Hutchinson (1884-1972), British botanist and plant collector. He was the son of a gardener and began work as a gardener in the arboretum at Kew, and later was a personal assistant to Dr. Otto Stapf. From 1907 to 1909 and again from 1916-1919 he was Assistant for India, and from 1909-1916 he was Assistant for Africa. From 1919 to 1936 he was in charge of the African section, and then was Keeper of Museums until his retirement in 1948. He made enormous contributions to the flora and botany of southern Africa, and was the author Common Wild Flowers (1945), More Common Wildflowers (1948), Uncommon Wildflowers (1950), British Wild Flowers (1955), The Genera of Flowering Plants (in 3 vols. 1964, 1967), A Botanist in Southern Africa (1946) based on his two collecting expeditions to southern Africa, and Evolution and Phylogeny of the Flowering Plants (1969). He was also the series editor of Flora of West Tropical Africa. Most of his work was illustrated by himself. He accompanied General Smuts on a trip to the northern Transvaal in 1928 and Dr. Pole Evans to the Magalakwin River in 1929. In 1930 he made a second trip to southern Africa and joined an expedition arranged by General Smuts to Lake Tanganyika. He received many prestigious awards and honors including the Order of the British Empire, and was elected a Fellow of the Royal Society in 1947. He was also honored by the genus Hutchinsonia which does not appear in southern Africa. He collected Amphibolia hutchinsonii, Elegia hutchinsonii and the former taxa Argyroderma hutchinsonii (now A. fissum), Ruschia hutchinsonii (now R. laevis), and Cheiridopsis hutchinsonii (now C. namaquensis), and can be presumed to be the honoree of these names. There are other taxa with the same epithet such as Hippia hutchinsonii, Pteronia hutchinsoniana, and former species Helichrysum hutchinsonii (now H. pumilio) and Dioscorea hutchinsonii (now D. dregeana). (JSTOR; Kew Bulletin Vol. 29, No. 1, 1974; Gunn & Codd; Wikipedia)

Huttonaea/huttoniae: for Mrs. Henry Hutton (née Caroline Atherstone) (1826-1908), a plant collector with her husband in South Africa and sister of British-born botanist William Guybon Atherstone (1814-1898).

(Gunn & Codd; JSTOR)

Hyacinthus
: after Hyacinth, in mythology a youth much beloved of Apollo, who was accidentally struck by a discus thrown by Apollo and killed. Supposedly, Apollo and the wind god Zephyrus had a sort of rivalry for Hyacinth's affections, and it was Zephyrus who blew the discus off course (or at least this is what Apollo believed), resulting in Hyacinth's death. In grief Apollo caused the hyacinth flower to rise from the youth's blood. The genus Hyacinthus in the Hyacinthaceae was published by Swedish botanist Carl Linnaeus in 1753.



Ibbetsonia: for Mrs. Agnes Ibbetson (1757-1823), British vegetable physiologist who contributed dozens of articles on the microscopic structure and physiology of plants to Nicholson's Journal and the Philosophical Magazine between 1800 and 1822.

immelmaniae: for a Mrs. Immelman of Piquetberg, South Africa, who collected Stapelia immelmaniae and Lampranthus immelmaniae. Eggli & Newton say that Mrs. Immelman "collected the plant around 1927" without saying which plant they are referring to, Stapelia or Lampranthus. However, the only Immelmans in JSTOR records are Kathleen Leonore Immelman (1955- ), co-author of Part 9: Urticaceae of Flora of Southern Africa, and an E.P. Immelman (1929- ) with no further information, and neither of them can be the one mentioned above (Etymological Dictionary of Succulent Plant Names; Women and Cacti)

The genus was Imshaugia in the Parmeliaceae published in 1985 by American lichenologist Susan Lynn Fricke Meyer. (Michigan State University Herbarium)

inae: for Lady Ina Oppenheimer (née Caroline Magdalen Harvey) (1899-1971), first married to Sir Kurt Michael Oppenheimer (1892-1933), then after his death in an airplane crash to Sir Ernest Oppenheimer (1880-1957), the German-born diamond and gold mining entrepreneur, financier and philanthropist, who controlled the De Beers Company and founded the Anglo American Corporation of South Africa, and who was Michael's uncle (Michael's father being Ernest's elder brother Bernard). Sir Ernest was struck by a series of tragedies that would have crushed many a lesser man, beginning in September 1933 with the death of his nephew Michael, followed by that of his first wife Mary in February 1934, then his brother-in-law Leslie Pollak in June of that same year, and then his youngest son Frank in April 1935, then his close associate Sir Basil Blackett in a car accident in August, and then a friend of many years standing Sir Frank Meyer in October. But in June 1935 he had married his nephew's widow Caroline Harvey and she brought him great happiness. She is commemorated with the former taxon Lithops inae, now synonymized to L. verruculosa.

Ingenhoussia: for Jan Ingenhousz or Ingen-Housz (1730-1799), Dutch physiologist, biologist and chemist. "He is best remembered for showing that light is essential to plant cellular respiration, a vital step in the discovery of photosynthesis. He was a physician to the Austrian Empress Maria Theresa. He carried out research in electricity, heat conduction, and chemistry, and met both Benjamin Franklin and Henry Cavendish. In 1785 he described the irregular movement of coal dust on the surface of alcohol, and therefore has a claim as discoverer of what came to be known as Brownian motion. Ingenhousz was elected a Fellow of the Royal Society of London in 1779."  The genus Ingenhoussia in the Fabaceae was published in 1835 by German botanist Ernst Heinrich Friedrich Meyer. (David Hollombe, pers. comm.; Wikipedia)

ioniana/ionii: for Ion James Muirhead Williams (1912-2001), South African engineer and amateur botanist who published A Revision of the Genus Leucadendron and helped to create the Fernkloof Nature Reserve above Hermanus.

irmae: for Mrs. Irma Burger (fl. 1997), wife of Willem Burger, owner of Aggeneys Farm, commemorated with Conophytum irmae. (Etymological Dictionary of Succulent Plant Names)

Iris: the CRC World Dictionary of Plant Names says that the origin of this name is the "Latin iris and Greek iris, ireos, iridos, 'the rainbow, a sweet-smelling plant, the Greek goddess of the rainbow and messenger of the gods.'" So whether this name commemorates the goddess Iris or merely is derived from words which were used for the name of the goddess is not absolutely clear. This is one of the many genera published in 1753 by Swedish botanist Carl Linnaeus, and it is in the Iridaceae.

isabellae: for Mrs. Isabella King (fl. 1938), housewife in Port Elizabeth, commemorated with Haworthia isabellae. (Etymological Dictionary of Succulent Plant Names)

jackvancei: for Jack Vance (1916- ), science-fiction author. The taxon Didymodon jackvancei was named by botanist Richard Zander in honor of his favorite science fiction writer. (Richard Zander, pers. comm.)

Jacobaea/jacobaea/Jacobaeastrum: the BackyardGardener.com and the Paghat's Garden website imply that both the generic and specific epithet here are named for St. James (Jacobus), one of the Twelve Apostles. One of the well-known taxa with this specific epithet is Senecio jacobaea (syn. Jacobaea vulgaris), common name St. James wort or tansy ragwort. James was the patron saint of wandering pilgrims, who were reputed to use tansy ragwort as a balm to soothe their aching feet. This plant reputedly flowers around the time of St. Jacob's Day at the end of July. Another website, the Poison Garden website, says "Possibly derived from St James or Jacobus. The phrase ‘conditio Jacobaea’ is used to mean ‘If the Lord wills it’ and is said to come from St. James’ instruction to examine all plans to see if they meet God’s will.  It may be that the pernicious ragwort could only be tolerated on the basis that it was part of God’s will. Images of St James tend to show him as an older man with grey or greying hair, somewhat unkempt.  It may be that the ragwort was thought to look like St James’ beard.” The taxa in southern Africa which formerly were included in Jacobaea are all now in the genus Senecio, and those that were in Jacobeastrum are now in Euryops. The former taxon Paraspalathus jacobaea is now Aspalathus quinquefolia. The genus Jacobaea in the Asteraceae was published in 1754 by Scottish botanist Philip Miller, and Jacobaeastrum was published in 1891 by German botanist Carl Ernst Otto Kuntze.

jacobi: for Kurumthottical Cherian Jacob (1890-1972), Indian botanist commemorated with the former taxon Scirpus jacobi, now Schoenoplectus senegalensis. (David Hollombe, pers. comm.)

jacobii: for Robert Jacob Gordon (1743-1795), Dutch explorer, soldier, artist, naturalist and linguist of Scottish descent. He was the son of Maj. General Jacob Gordon of the Scots Brigade which was in service to the Netherlands, and he was born in Doesburg, Gelderland, the Netherlands, and died at Cape Town. He joined the Dutch East India Company and commanded the Cape Garrison. He went on more expeditions than any other 18th-century explorer of southern Africa. On his first trip he travelled with Carl Peter Thunberg and Francis Masson. His second trip he undertook with the botanist William Paterson who unfortunately had to turn back. He was also accompanied by the artist Johannes Schumacher/Schoemaker who joined him on all of his trips. He was held in high regard by botanical collectors at the Cape and elsewhere. He met Lt. Bligh when the Bounty put in at the Cape in May 1788 and helped him procure seeds and plants. He also made a major contribution to wool farming in South Africa when he imported four Merino ewes and two rams from Holland. He is commemorated with the former taxon Pelargonium jacobii, now synonymized to P. klinghardtense, as well as Hoodia gordonii. (Proposals on Orthography/Preliminary inventory of the extent of Rec 60C.2 of the 2005 Vienna International Code of Botanical Nomenclature; Wikipedia; Gunn & Codd)

Jacobsenia/jacobseniana/jacobsenianum: for Hermann Johannes Heinrich Jacobsen (1898-1978), German horticulturist and botanist, specialist in succulent plants, author of many books on succulents, and Curator of the Kiel Botanical Garden 1929-1963. The genus Jacobsenia in the Aizoaceae was published in 1954 by South African botanist Harriet Margaret Louisa Bolus and German botanist Martin Heinrich Gustav Schwantes. He was also commemorated with the former southern African taxa Haworthia jacobseniana (now H. glauca), Crassula jacobseniana (now C. ericoides), Lithops jacobseniana (now L. karasmontana), Argyrodermum jacobsenianum (now A. congretum) and possibly also Leipoldtia jacobseniana (now L. schultzei) and Cotyledon jacobseniana (now C. papillaris). (Etymological Dictionary of Succulent Plant Names)

jacottetiae/jacottetiana/jacottetianus/jacottetii: for Hélène A. Jacottet (c.1867-?), botanist, from Neuchatel, Switzerland, and/or one or the other of her brothers, one of whom was a Dr. Gustave Adolph Jacottet (1870-?), one was Henri, and the other was the missionary Rev. Édouard Jacottet (1858-1920), a member of the Paris Evangelical Missionary Society, author of A Practical Method to Learn Sesuto, considered one of Lesotho's greatest churchmen, who was murdered by arsenic poisoning at lunch at the Mission Station at Morija in December 1920, which was recounted in the book Murder at Morija by Tim Couzens. Five other people were poisoned but only the Reverand died. His sister Hélène's birth date given above is from a ship passenger list arriving in England from Durban in 1914, provided by the indefatigable David Hollombe. The JSTOR collector records list her as fl. 1905-1914. There is one online reference to Hélène Jacottet at Whitehill, Qacha's Nek District. (Lesotho) c. 1910, probably the same person. She is commemorated with the former Rhynchosia jacottetii (now R. reptabunda), Satyrium jacottetiae, which is now S. membranaceum, the former Chaenostoma jacottetianum, probably for Disa jacottetiae (now D. crassicornis), and Senecio jacottetianus and Dipcadi helenae which do not appear in southern Africa. There are also taxa named Ursinia jacottetiana (now U. montana), Sonchus jacottetianus and Lotononis jacottetii which almost certainly honor one or the other of this trio. The only Jacottet listed in the Harvard University Herbaria list of botanists has a birth date of 1914, so I'm not sure who this is, but the JSTOR records also include mention of a Dr. Lautrè Jacottet (fl. 1903-1905) listed with associates Rev. Henri-Alexandre Junod (1863-1934) and H. Jacottet fl. 1905-1914 (co-collector, sister). Murder at Morija gives her parents as Henri-Pierre and Louise-Isabelle Jacottet, her sisters as Isabelle and Cecile-Louise, and her brothers as Gustave, Henri and Édouard Jacottet, while Gunn & Codd record her brothers as Édouard Jacottet and the aforementioned Dr. Lautrè Jacottet, who was apparently also associated with the Paris Evangelical Missionary Society in Lesotho and East Griqualand. There is an obituary in the Journal of the Medical Association of S.A. from 1929 of a Dr. Gustave Jacottet who graduated M.D. at Lausanne 1897 and came to the Cape in 1899. He served with Republican forces in the South African War and with a Serbian unit in WWI. The funeral was attended by many Griquas and other native people who considered him a friend, but there is no mention of any connection between him and other members of the Jacottet family, so I don't know if some confusion has crept into some of these accounts. If anyone can shed further light on this interesting matter, please contact me. (Gunn & Codd; JSTOR; David Hollombe, pers. comm.)

Jacquemontia: for Venceslas Victor Jacquemont (1801-1832), French naturalist, explorer, plant collector, botanist, made collections for the Royal Museum of Paris . According to the website of the American Philosophical Society, "Born in Paris on August 8, 1801, the youngest of four sons of Venceslas Jacquemont and Rose Laisné, Victor Jacquemont was one of the rising stars of French natural history in the 1820's and an archetype for the scientist in the Romantic era. Combining youth, genius, and a rhapsodic love of nature with a life filled with masculine affection, star-crossed romance, and exotic climes, Jacquemont epitomized the romantic intellectual right up to the time of his untimely death in the Himalayas. In a career in which ill fortune and good fortune walked hand in hand, the figure of Jacquemont has all but overshadowed his substantial scientific accomplishments. The surviving correspondence of the ill-starred French botanist Victor Jacquemont and his friend Pierre Achille Marie Chaper (1795-1874) consists of 106 letters pertaining to the development of Jacquemont's scientific career and their personal and social commitments." Although he may have become ill while in the Himalayas, he died of dystentery in a military hospital in Bombay at the young age of 31. The genus Jaquemontia in the Convolvulaceae was published in 1836 by French botanist Charles Paulus Bélanger. (CRC World Dictionary of Plant Names)

Jacquesfelixia: for Henri Jacques-Félix (1907-2008), French botanist, explorer and plant collector in West Africa (Guinea and the Ivory Coast), affiliated with the Musée National d'Histoire Naturelle, Paris, France, author of La Vie et La Mort du Lac Tchad. The genus Jacquesfelixia in the Poaceae was published in 1964 by Canadian botanist James Bird Phipps. His name is also on Pitcairnia feliciana, the only bromeliad that grows outside the New World which he discovered. (CRC World Dictionary of Plant Names)

jacquiniana/jacquinianum/jacquinii: for Nicholaus (Nicolaas or Nikolaus) Joseph von Jacquin (1727-1817), Dutch scientist who studied medicine, chemistry, mineralogy and botany. Born in the Netherlands, he later moved to Paris and then Vienna. In 1754, his friend Gerard van Swieten, professor of medicine at the University of Vienna and physician to the Empress Maria Theresa, proposed that the Emperor, Franz I Stephan, commission an expedition to the Caribbean. The Emperor was acquainted with Jacquin and decided to send him on the mission to collect tropical plants and other 'curiosities' from the Caribbean for the palace's natural history collections. He departed the next year with the gardener Richard van der Schot (see Schotia) and two bird collectors. The expedition lasted four years and visited the islands of St. Vincent, Grenada, Curaçao, Aruba, Venezuela, Colombia, Guadeloupe, St. Kitts, St. Eustatius, St. Maarten, St. Barthélemy, Santo Domingo (now Haiti and the Dominican Republic) and Cuba, returning to Vienna in 1759. He published a listing of his discoveries as Enumeratio Systematica Plantarum (1760) and a more detailed description, the Selectarum stirpium americanarum historia in 1763. He spent six years as a professor in chemistry and metallurgy in Hungary and in 1769 he took up the position of Chair of Botany and Chemistry at the University of Vienna (a position he held until 1797) and became Director of the University's Botanical Gardens, and in 1809 became Rector of the University. He also supervised the gardens at the imperial palace of Schönbrunn. His son, Joseph Franz von Jacquin (1766-1839), was also a professor and botanist. The taxa in southern Africa that bear these specific epithets are Trachyandra jacquiniana, Albuca jacquinii, Lapeirousia jacquinii and the former taxon Duvalia jacquiniana (now D. elegans). N.J. von Jacquin was also honored with the generic names Jacquinia and Jacquiniella, neither of which appear in southern Africa. (Wikipedia; JSTOR)

Jaegerina: for August Jaeger (1842-1877), Swiss bryologist and author of Genera et Species Muscorum who had a herbarium of 12,500 specimens of mosses, which has become a core component of the William C. Steere Bryophyte Herbarium at the New York Botanical Gardens. The genus Jaegerina in the Pterobryaceae was published in 1876 by German bryologist Johann Karl August Müller.

jakubii: for Jakub Jilemicky (1980- ), Czech succulent enthusiast and grower, commemorated with the questionably valid taxon Haworthia jakubii. Published by Ingo Breuer in 2004, it is not considered valid by Tropicos, nor is it listed in the POSA database of southern African species, from where it was supposedly collected, and it seems likely that this specimen was simply an odd or slightly different example of some other Haworthia, perhaps H. mirabilis. (All You Wanted to Know About Haworthias and Gasterias)

Jamesbrittenia: for James Britten (1846-1924), British botanist and Keeper of Botany of important collections at the British Museum during the 1800’s. He was also an authority on Old English dialects and folklore. From an obituary in The Times: "Born at Chelsea on May 3, 1846, he was educated privately and intended to become a doctor. At the age of 21 he was received into the Roman Catholic Church, and two years later, having been offered a post in the Kew Herbarium, he gave up his medical studies. In 1871 he was transferred to the Botanical Department of the British Museum a volume of illustrations of the Australian plants collected by Banks and Solander; he edited Turner's 'Names of Herbs'; he started a catalogue of the Sloane Herbarium; with R. Holland he compiled a dictionary of English and Irish botanists; and for eight years he edited Nature Notes, and was editor of the Journal of Botany from 1880 till his death. Britten was made a fellow of the Linnean Society in 1870m and was an original member of the Folklore, English Dialect, Bibliographical, and Catholic Record Societies. Besides actively helping in the work of these societies he published 'Old Country and Farming Words,' and an edition of Aubrey's "Remaines of Gentilisme." Lest it be thought that he had no other life than botany and scholarly pursuits, I quote again from his obituary: "But his principal work was the Catholic Truth Society, which he was chiefly instrumental in restarting in 1884... The society's steady progress for the last 40 years is chiefly due to him. Mr. Britten also started the annual conferences which, after 21 years, were merged into the National Catholic Congress. For his services Pope Leo XIII. made him a Knight of St. Gregory in 1897, and 20 years later he was promoted to Knight Commander con placea. The genus Jamesbrittenia in the Scrophulariaceae was published in 1891 by German botanist Carl Ernst Otto Kuntze. (Hugh Clarke, pers. comm.; Wikipedia)

jamesii: for Mr. H.W. James (fl. 1931) of Cradock, Eastern Cape, collector of succulents. (Etymological Dictionary of Succulent Plant Names)

Jamesonia/Jamesoniella: for William Jameson (1796-1873), Scottish botanist."William Jameson was born in Edinburgh in 1796 and studied at Edinburgh's Royal College of Surgeons ca. 1814-1818. Between 1818 and 1826, he made several voyages as a ship's surgeon, first to Baffin's Bay and later to South America. In 1826 he settled in Quito, Ecuador, and in the following year he was appointed professor of chemistry and botany at the University there. He was made assayer to the mint in 1832 and director in 1861. In 1869 he went back to Edinburgh (by way of Argentina) to visit his sons, and returned to Ecuador in 1872. He died shortly thereafter. Jameson carried out botanical investigations at Baffin's Bay, in Ecuador, and in other South American countries; corresponded with Scottish and British botanists; sent plant specimens back to Great Britain (possibly elsewhere?); and published articles in a half dozen British and Scottish botanical journals. In 1864 he was appointed by the Ecuadorean government to write a flora of Ecuador. Volumes 1 and 2 of his Synopsis Plantarum Aequatoriensium (in Spanish) were published in 1865, but the work was not completed. [The British Museum has the text of the unpublished 3rd volume, p. 1-136; the U.S. Department of Agriculture Library has a Photostat of this.] Jameson apparently also continued his studies of chemistry, as one would expect from his position as assayer to the mint. The biographical sources consulted did not mention any correspondence with chemists or any publications on chemistry, but the Gray Herbarium archives contain what appears to be a manuscript for a text on chemistry, probably never published." The genus Jamesoniella in the Jungermanniaceae was published in 1881 by British botanist Benjamin Carrington, while the genus Jamesonia in the Adiantaceae was published in 1830 by British botanists William Jackson Hooker and Robert Kaye Greville.

jamesonii: for (1) Professor William Jameson (1796-1873), Scottish physician and botanist who collected in South America, commemorated with Campylopus jamesonii and Cryphaea jamesonii, both of which he collected. See previous entry. (JSTOR); (2) Robert Jameson, who collected live specimens while on a prospecting expedition to Barberton District in 1884, even though Gerbera jamesonii had been collected on three earlier occasions by other people. (PlantzAfrica).

jansei: for Anthonie Johannes Theodorus Janse (1877-1970), Dutch biologist, entomologist, teacher and one of the leading authorities on South African moths, emigrated to South Africa, amassed a collection of 100,000 specimens of moths that is housed in the Transvaal Museum, five times president of the South African Biological Society. He collected Delosperma jansei in the Barberton area of South Africa in 1911 and is commemorated with its name. (Gunn & Codd; JSTOR)

jarmilae: for Jarmila Haldová (fl. 2002), wife of Czech botanist and cactus specialist Josef J. Halda (1943- ), commemorated with Tylecodon jarmilae, Conophytum jarmilae and probably Moraea jarmilae (Etymological Dictionary of Succulent Plant Names; Women and Cacti)

Jaumea: for Jean Henri Jaume Saint-Hilaire (1772-1845), French botanist, naturalist historian and artist who compiled, inter alia, a major work on some 2,337 genera and about 4,000 species with 112 plates drawn by himself (1805); published Plants of France described and painted from nature (10 volumes, 1808-1822), gathering a thousand engravings by himself; and contributed to Dictionaire des Sciences naturelle. The genus Jaumea in the Asteraceae was published in 1807 by South African mycologist Christiaan Hendrik Persoon. (CRC World Dictionary of Plant Names, Wikipedia)

jeanae: for Jean Helen Edwardes Brenan, wife of the author of Thesium jeanae, British botanist John Patrick Micklethwait Brenan. (David Hollombe, pers. comm.)

jeffreysii: for Dr. Mervyn David Waldegrave Jeffreys (1890-1975), colonial administrator, anthropologist and plant collector in Rhodesia. He served for many years in the civil service of Nigeria, including a period on the bench in 1936. For more than ten years he was a staff member of the Department of Social Anthropology at the University of Witwatersrand. He is the author of "List of Grasses Collected at Bulawayo," Samsonic Suicides: or Suicides of Revenge Among Africans and Some Semitic Influences in Hottentot Culture. He is commemorated with Eragrostis jeffreysii, Schizachyrium jeffreysii and the former taxon Stereochlaena jeffreysii, which is now synonymized to S. cameronii. (Etymological Dictionary of Grasses; David Hollombe, pers. comm.)

jenkinsii: for Thomas J. Jenkins (fl. 1909-1911), plant collector, "an assistant at the Transvaal Museum who collected thousands of plant specimens in southern Africa (Mozambique and South Africa) during the time that Reino Leendertz was curator." He is commemorated with Alepidea jenkinsii. (JSTOR)

Jensenia: for Thomas Jensen (1824–1877), Danish bryologist and teacher in Ranum, Denmark, author of Bryologia danica eller de danske bladmosser (1856), collected in Denmark and Norway. The bryophyte genus Jensenia in the Pallaviciniaceae was published by Swedish physician and botany professor Sextus Otto Lindberg in 1867. (Fieldiana: Botany, Chicago Natural History Museum 2008)

Jensenobotrya: for Emil Jensen (1889-1963), German naval officer, accountant, farmer and amateur botanist who had emigrated to Namibia from Germany. "During World War 1, he joined the German Royal Navy and  became a Lieutenant.  In 1936 he emigrated to Tsumeb, S.W. Africa, where his interest in succulents commenced.  From 1940 to 1943, he was held at the Andalusia internment camp in South Africa, then repatriated to Germany.  In Andalusia  he attended lectures by Hans Herre, Custodian of Stellenbosch Herbarium, which considerably improved his botanical knowledge. Jensen had a special interest in Namib flora, especially Welwitschia bainesii, and for a number of years  made expeditions to the Central  and Southern Namib Desert (and elsewhere), often with botanical colleagues like Hans Herre, Willy Giess, and others. He published a few botanical papers and made a detailed study of the Nara plant (Acanthosycios horrida). In 1955 he returned to S.W. Africa where he was responsible for developing the outstanding botany section of the Swakopmund museum." The genus Jensenobotrya in the Aizoaceae was published in 1951 by German botanist and explorer Adolar Gottlieb Julius Herre. (CRC World Dictionary of Plant Names)

jeppei: for Dr. Theodor Jeppe (1896-1956), medical doctor and plant collector in South Africa who travelled to many southern Cape towns in the 1930's. The plant in southern Africa with this epithet is Erica jeppei, which he collected in South Africa in 1933. (JSTOR; Ted Oliver, pers. comm.)

joeyae: for Joey Scott, wife of Col. Charles Leslie Scott (1913-2001), who named Haworthia joeyae in 1995. (David Hollombe, pers. comm.)

johannis: the taxa in southern Africa with this epithet are Streptocarpus johannis and the former Hydnora johannis (now synonymized to H. abyssinica) and Tiliacora johannis (now synonymized to T. funifera). There are many taxa with this specific epithet and they usually refer to someone or some place with John in the name. PlantzAfrica says that the specific epithet in Streptocarpus johannis is derived from Port St. Johns where it was first collected. At least one taxon, Euphorbia johannis, commemorates John Jacob Lavranos (1926- ). I found one source that listed an article about Hydnora johannis by Lytton John Musselman, but this may be a false clue. The taxon Tiliacora johannis and other taxa were collected by botanist John Gossweiler. This one is pretty much up in the air. (PlantzAfrica; JSTOR)

johannis-simae: for a Joannes Sima or Sima János, Hungarian friend of the author of Parmelia joannes-simae, Vilmos Köfaragó Gyelnik (1906-1945), Hungarian botanist, mycologist and lichenologist. (David Hollombe, pers. comm.)

johannis-winkleri: for Hans Karl Albert Winkler (1877-1945), German professor of botany at the University of Hamburg and director of the botanical garden who coined the word 'genome' in 1922, author of Parthenogenesis Und Apogamie Im Pflanzenreiche (1908), commemorated with Crassula johannis-winkleri. There are also taxa in southern Africa named Conophytum johannis-winkleri, Mesembryanthemum johannis-winkleri and a former taxon named Cheiridopsis johannis-winkleri, now synonymized to Cheiridopsis schlecteri, but I don't know whether those have the same derivation. However, at least six other taxa with this specific epithet that do not appear in southern Africa were named for Hans Winkler, so it seems likely that his name is on the African species as well. (David Hollombe, pers. comm.)

johanssenii: Hermannia johanssenii was collected by a Y. Johanssen in the Calvinia area of South Africa in 1899, so I assume this is who it is named for. No further information available. (JSTOR)

johni-lavrani: for John Jacob Lavranos (1926- ), Greek-born botanist and insurance broker, came to South Africa in 1952, collected extensively in many remote areas, commemorated with the former taxon Stapelia johni-lavrani, now synonymized to S. hirsuta var. gariepensis. See also lavrani and Lavrania.

johnsonii: for William Henry Johnson (1875-?), Director of Agriculture in the Mozambique Company, commemorated with Androstachys johnsonii and Euphorbia knuthii ssp. johnsonii. (Trees and Shrubs of Mpumalanga and Kruger National Park; Encyclopedia of Succulents CactusPro.com)

johnstonii: for (1) Sir Henry (Harry) Hamilton (1858-1927), British administrator and explorer, who collected in Kenya, and led a scientific expedition to Mt. Kilimanjaro in 1884. His work in the region was under the direction of Sir John Kirk in Zanzibar, and it is to be expected that at least part of what was accomplished was a collection of plant specimens. In 1900 in the Congo he discovered and named the okapi, an animal new to science. His name is connected with many other floral and faunal discoveries and he received several medals from the Zoological Society and the Royal Geographical Society. He collected Aneilema johnstonii, and is probably commemorated with Leptaloe johnstonii and Disperis johnstonii as well. (JSTOR): (2) Peter Johnston (fl. 1996), British succulent plant enthusiast of Guernsey, commemorated with Gibbaeum johnstonii. (Etymological Dictionary of Succulent Plant Names)

jonasiana: Erica jonasiana, named after the peak Jonaskop which in turn was named for some person called Jonas. (Ted Oliver, pers. comm.)

jonesiae: possibly for a Mrs. E. Jones, about whom I know nothing, but maybe Eustace Wilkinson Jones (1909-1992), British botanist on the JSTOR list of plant collectors, author of Hepatic Flora of West Africa. The taxon in southern Africa with this epithet is Haworthia jonesiae, published in 1937 by German agronomist Dr. Karl von Poellnitz who was a significant collector of Haworthias and other succulents. Another source seems to indicate that the collection was made by a Mrs. K.E. Jones, so this is uncertain.

jordaanianum/Jordaaniella: for Professor Pieter Gerhardus Jordaan (1913-1987), Professor of Botany at the University of Stellenbosch in 1984 and a specialist in the Proteaceae. The genus Jordaaniella in the Aizoaceae was published in 1983 by Heidrun Elsbeth Klara Osterwald Hartmann and Professor Jordaan may also have been commemorated with the taxon Glottiphyllum jordaanianum. (CRC World Dictionary of Plant Names)

josephinae: for (1) Dr. Josephine (Jo) Beyers, assistant curator of the Compton Herbarium, commemorated with Felicia josephinae. (PlantzAfrica); (2) the Empress Josephine (1763-1814), Napoleon's first wife. The taxon that bears this epithet is Brunsvigia josephinae. (PlantzAfrica).

joubertiana: for Hester Joubert (later Mrs. Reitz) (c.1805-?), considered as the first South African-born woman plant collecter. She collected mainly in Bredasdorp District. Her brother, the advocate Joshua Andries Joubert, had an estate at the foot of Table Mountain a part of which was used by C.F. Ecklon to grow plants. Hermannia joubertiana, Aspalathus joubertiana and Agathosma joubertiana were all named for her. (Gunn & Codd; JSTOR)

joubertii: for Adriaan Jacobus Joubert (1901-?), South African science and biology teacher, an authority on the flora of the Little Karoo, maintained a collection of succulents at his home. Hereroa joubertii, Conophytum joubertii and Sceletium joubertii (now synonymized to S. tortuosum) were named in his honor. (Etymological Dictionary of Succulent Plant Names; Gunn & Codd)

joubertinae: Felicia joubertinae was collected by Elsie Elizabeth Esterhuysen in Joubertina in the Uniondale Division of South Africa in 1941 and thus was not named for a person. This is the only taxon I know of that has this specific epithet.

Jubaeopsis: the genus Jubeae was named for King Juba (c. 85-46 BC, reigned 60-46 BC) of Numidia, ancient North African country. The genus Jubaeopsis in the Arecaceae, which means 'having the appearance of Jubaea, was published in 1913 by Italian naturalist Odoardo Beccari. (CRC World Dictionary of Plant Names)

Julbernardia: for Marie Joseph Jules Pierre Bernard (1876-?), Lieutenant Governor of Gabon from 29 July 1924 to 19 June 1931. François Pellegrin published the genus Julbernardia in the Fabaceae in 1943. (CRC World Dictionary of Plant Names; Governors of Gabon; WorldStatesmen.org)

julii: for Dr. Julius Derenberg (1873-1928), succulent grower of Hamburg, and friend of Professor Kurt Dinter who collected Lithops julii ssp. julii in 1924. Dr. Derenberg was also commemorated with the species Anisodontea julii, as well as Cheiridopsis derenbergiana and Ebracteola derenbergiana. His wife was Louisa Martha Derenberg Louisa Martha Derenberg (née Warburg) (1879-1973), commemorated with Derenbergiella luisae. (The Names of Plants; Wikipedia)

Jumellea/jumelleanus: for Henri Lucien Jumelle (1866-1935), noted French botanist originally trained as a pharmacist, plant physiologist at Paris and Marseilled and plant collector in Madagascar, Director of the Musée Colonial of Marseille, and author on the subject of economic botany in Madagascar. JSTOR says that it is doubtful that he ever collected in Africa proper. The genus Jumellea in the Orchidaceae was published in 1914 by Friedrich Richard Rudolf Schlechter, and Jumella was also commemorated with the genus Jumelleanthus which does not appear in southern Africa. Two former taxonomic names that are both synonyms for Eulophia livingstoneana are Eulophia jumelleana and Lissochilus jumelleanus, with no information as to the derivation of those names. (CRC World Dictionary of Plant Names; JSTOR)

Jungermannia/jungermanniae: for Ludwig Jungermann (1572-1653), a professor of botany in Giessen and Altdorf bei Nürnberg. I'm not sure who the former Lenormandia jungermanniae was named for (usually the 'ae' ending indicates a woman). The genus Jungermannia in the Jungermanniaceae was published by Linnaeus in 1753. There were two names, both synonyms of Normandina pulchella, Normandina jungermanniae and Lenormandia jungermanniae, with no information as to the derivation of the name jungermanniae.

junodianus/junodii: for Rev. Henri Alexandre Junod (1863–1934), a Swiss missionary stationed for much of his career at Shiluvane in Limpopo Province. His collection of plants from there, the lowveld of Mpumalanga and parts of Mozambique, is an important early historical record of the flora of these areas. Author of Life of a South African Tribe. He is commemorated with Senecio junodii, Helichrysum junodii, Anisopappus junodii, the former Casearia junodii (now C. gladiiformis), Dolichos junodii, Indigofera junodii (now I. colutea), Thesium junodii, Corchorus junodii, Selago junodii, Striga junodii and possibly Kalanchoe junodii (now K. lanceolata). (Elsa Pooley; JSTOR; PlantzAfrica)

Juratzkaea: for Jacob Juratzka (1821-1878), Austrian or German physician and bryologist, author of numerous papers on mosses. The genus Juratzkaea in the Stereophyllaceae was published in 1866 by Paul (Pablo) Günther Lorentz. (David Hollombe, pers. comm.)

juritzii: probably for Dr. Charles Frederick Juritz (1864-1945), analytical chemist and traveller, author of South African Plant Poisons and Their Investigation. He was a pioneer in the study of soils in the Cape Colony, also worked on underground water and crops. He was elected President of the Southern Africa Association for the Advancement of Science, and is commemorated with the former taxonomic names Mesembryanthemum juritzii and Carpobrotus juritzii, both of which have been synonymized to Carpobrotus dimidiatus. (JSTOR)

Justicia: for James Justice (1698-1763), a Scottish horticulturist, botanist, and clerk of sessions, author of The Scots Gardiners Director and The British Gardener's Calender. He was supposedly the first person in England to grow a pineapple to the fruiting stage. He was elected a fellow of the Royal Society in 1730 and ejected in 1757, but continued to use the FRS after his name. He went to Holland several times to study the culture of tulips and spent a great deal buying bulbs at the nurseries of Haarlem. He was most particular when it came to the compost he used in his gardens and was said to use a recipe as detailed as for a fine fruit cake. He also imported seeds, roots and trees. His expenditures were always greater than his income, and in the end they ruined him and he lost his house and fortune, all of his plants being put up for auction. The genus Justicia in the Acanthaceae was published by Linnaeus in 1753. (CRC World Dictionary of Plant Names; The Plant Press Vol 5, No. 4, 2002)

Juttadinteria/juttae: for Mrs. Helena Jutta Dinter (née Schilde), wife of German botanist and explorer Moritz Kurt Dinter.

His book Amoenitatum Exoticarum was published in 1712 and contained the first extensive description of Japanese plants and such things as the electric eel and acupuncture. The genus Kaempferia in the Zingiberaceae was published by Linnaeus in 1753. (CRC World Dictionary of Plant Names; Wikipedia)

kaessneri: possibly for L.C.T. Kaessner (fl. 1902-1910), plant collector in the Congo and Zambia. The genus in southern Africa with this specific epithet is the former Erythrina kaessneri now synonymized to Erythrina abyssinica.

Hugh Clarke has provided the following: "He studied at the Universities of Åbo (now Helsincki) (1735-1739) and Uppsala (1740-1741) under Carl Linnaeus. He did research work in Sweden, Russia and the Ukraine (1742-1745) before becoming a senior lecturer (Docent) (1746), then professor of Natural History and Economics at the Academy of Turku (1747). In 1748 he was sent by the Academy of Sciences to North America and Canada to find seeds and plants that might be useful for agriculture or industry. He wrote a 3-volume account of his travels into North America (1770-1772), which was translated into English, visiting Niagara Falls, and Montreal and Quebec. He returned to Finland in 1751 to his post as Professor at the Turku Academy and taught there until his death." The genus Kalmia in the Ericaceae was published in 1753 by Swedish botanist Carl Linnaeus. (CRC World Dictionary of Plant Names; Hugh Clarke)

kammanassieae: Erica kammanassieae, named for the type locality of the kammanassieae Mountains.

karsteniae: for Maria ("Mia") Caroline Karsten (1902-?), botanical historian and collector, born in Holland, secretary of the Netheralands Society of Succulent Collectors, co-author with N.E. Brown and A. Tischer of Mesembryanthema and author of The Old Company's Garden at the Cape and Its Superintendents, emigrated to South Africa in 1947, for almost 15 years assisted R.H. Compton in his botanical survey of Swaziland. She is commemorated with the taxon Epilobium katsteniae. (Gunn & Codd)

karvinskianus: possibly for a Wilhelm Karvinsky, German botanist and plant collector. The taxon in southern Africa with this specific epithet is Erigeron karvinskianus. However JSTOR records show that this taxon was collected by a W.F. Karwinski von Karwin. This was the Baron Wilhelm Friedrich Karwinski von Karwin (Karvin) (1780-1855), Hungarian-born German naturalist and plant collector in Brazil and Mexico who had special interests in botany, geology and fossils and who sent large numbers of specimens (over 4000), particularly of cacti, back to German and also to St. Petersburg, Russia. The taxon was collected in Oaxaca, Mexico and was published in 1836 by Swiss botanist August Pyramus de Candolle. (JSTOR)

karwyderi: Erica karwyderi, named after the locality, Karwyderskraal near Hermanus, In Afrikaans a karwyder is a transport rider. The type locality was on the farm Karwyderskraal. (Ted Oliver, pers. comm.)

kassneri/kassneriana/kassnerianum: for Theo Kassner, traveller and plant collector in Africa, author of My Journey from Rhodesia to Egypt (1911) and Gold Seeking in South Africa (1902). He collected and is commemorated with Cynorkis kassneriana and the former Heteromorpha kassneri, now synonymized to H. involucrata, and possibly also Ceropegia kassneri (now C. purpurascens) and Periglossum kassnerianum. (JSTOR)

katharinae: for Lady Katharine Saunders (1824-1901), a British plant collector and botanical artist who emigrated to South Africa at the age of 30 in 1854. She is the author of Flower Paintings of Katharine Saunders: Botanical and Biographical Notes and Explanations. The taxon Zaluzianskya katharinae was collected by Katharine Saunders in the Transvaal, also the former Haemanthus katharinae now synonymized to Scadoxus multiflorus, and she is commemorated with their names, and possibly also the taxon Clutia katharinae. (Elsa Pooley)

katzeri: for Franz Katzer (c.1823-?), a gardener at Pavlovsk. A work entitled La Belgique Horticole, Vol. 25, mentions that Stangeria katzeri was brought to bloom by a gardener named Katzer in the garden of the Grand Duke Constantine Nicolawitsch in St. Petersburg. He was apparently still alive in 1912. Stangeria katzeri has now been synonymized to S. eriopus. (David Hollombe, pers. comm.)

Kaulfussia: for Georg Friedrich Kaulfuss (1786-1830), German botanist, professor of botany at Halle, pteridologist, author of many plant names and the 1824 work Enumeratio Filicum, an illustrated book with botanical descriptions based upon the travels and collections of Ludolf Karl Adelbert von Chamisso, who served as botanist on the Russian voyage of exploration on the Rurik led by Otto von Kotzebue.. Hugh Clarke adds: "Chamisso collected some 165 ferns of which 77 were new to science. Kaulfuss honoured Chamisso by naming a small tree fern collected in Hawaii in 1821 after him." The genus Kaulfussia in the Asteraceae was published in 1820 by German botanist, physician and zoologist Christian Gottfried Daniel Nees von Esenbeck. (CRC World Dictionary of Plant Names)

Keetia/keetii: for Dr. Johan Diederik Möhr Keet (1882-1976), South African botanist and plant collector, and former Director of Forestry in the Union government 1935-1942. From Hugh Clarke: "During his career, he was Controller of Timber during World War II; a technical advisor to the Division of Soil Conservation and Extension, Department of Agriculture (1945-1955), also acting in an advisory capacity in South-West Africa, and Technical Advisor for the development of the Westfalia Estate, Northeastern Transvaal and residential director of afforestation work from 1956-1969. He collected fungi and other specimens around Stellenbosch, in the Knysna area, in the eastern and northeastern Transvaal, and in South-West Africa. Stellenbosch University awarded him an honorary Pd.D in 1964." Dr. Keet is commemorated with the taxa Psoralea keetii, Erica keetii, Searsia (formerly Rhus) keetii and the former taxon Bobartia keetii, now synonymized to B. aphylla, all of which were collected by him. The genus Keetia in the Rubiaceae was published in 1927 by South African botanist and taxonomist Edwin Percy Phillips. (CRC World Dictionary of Plant Names; Trees and Shrubs of Mpumalanga and Kruger National Park)

keilhackii: probably for Friedrich Ludwig Heinrich Konrad Keilhack (1858-1944), German geology professor in Berlin who collected in Namibia and South Africa. The taxon in southern Africa with this name was Adromischus keilhackii, synonymized to Tylecodon schaeferianus, and Keilhack is listed as one of the collectors of this taxon. (JSTOR)

After WWI he emigrated from England to Swaziland and was partners for a time with George Lloyd Wallis (1887-1978). He is also commemorated with Euphorbia keithii and Aloe keithii, and the former taxon Caralluma keithii, now synonymized to Orbea carnosa. (Elsa Pooley; Etymological Dictionary of Succulent Plant Names; Gunn & Codd)

Kennedia: for John Kennedy (1759-1842), English nurseryman, co-owner of the family business of Lee and Kennedy, a nursery called "The Vineyard" in Hammersmith, West of London, which was in operation for three generations. Wikipedia mentions that "They [Lee and Kennedy] were in correspondence with plant collectors in the Americas and with Francis Masson and others at the Cape of Good Hope, whence hardy and half-hardy plants and seeds were coming to be tested in English gardens and hothouses." Lee and Kennedy were part of a consortium that commissioned James Niven to collect in South Africa, another member of which was the Empress Josephine, whom Lee and Kennedy advised and supplied plants to.Hugh Clarke provides the following: "The co-founders, Lewis Kennedy (c.1721-1782) and James Lee (1715-1795), went into partnership about 1745. John Kennedy (1759-1842), who was raised in the business from a young age, succeeded his father and continued in business with the younger James Lee (1754-1824). Kennedy was a frequent contributor to the first five volumes of The Botanist's Repository (1799-1803), writing most of the notes accompanying the illustrations, and also wrote A Treatise upon Planting, Gardening, and the Management of the Hot House (1777)." According to George William Johnson's History of English Gardening (1829:301) as quoted in Robert Hardwicke's Journal of Botany, British and Foreign (1904), John Kennedy was the actual writer of the work purportedly by William Bridgwater Page entitled Page's Prodromus, as a General Nomenclature of All the Plants, Indigenous and Exotic, Cultivated in the Southampton Botanic Garden 1817. Page had been trained in the firm's nursery at Hammersmith, and married a daughter of John Kennedy and moved to Southampton, where he set up in business himself. The business Lee and Kennedy was later carried on by the third generation of Lees, the sons of James Lee the Younger, John Lee (c. 1805-1899) and Charles Lee (1808-1881). The genus Kennedia in the Fabaceae was published in 1805 by French botanist Étienne Pierre Ventenat. He also had the genus Kennedynella (which does not appear in southern Africa) named for him. (Journal of Botany, British and Foreign; Hugh Clarke, pers. comm.; Western Australia Plant Names and Their Meanings)

kennedyana/kennedyi: for Hermias C. Kennedy (1922- ), who according to JSTOR records collected Huernia kennedyana with John Jacob Lavranos in 1964 in the Cradock area of the East Cape and some sources say named to honor his wife. David Hollombe uncovered this quote from Lavranos in the Journal of South African Botany (31:315): "This unusual species was collected, together with other plants, at the request of Mr. H.C. Kennedy of Bellville, Cape Province, during the January, 1964, school holidays by one of his pupils on Mr. A.C.A. Lombaard's farm Welbedaght." Further he gives the location of the holotype as "Farm Welbedaght, 10 miles from Cradock on the road to Graaf-Reinet." Kennedy also collected Conophytum kennedyi in 1926. (JSTOR; Women and Cacti; David Hollombe, pers. comm.)

Kensitia: for ée Kensit) (1877-1970), South African botanist, daughter-in-law and grand-niece of Harry Bolus and curator of the Bolus herbarium from 1903 until her retirement in 1955, studied Ericaceae and Orchidaceae in her early career, later Iridaceae and Aizoaceae; wrote many scholarly as well as less academic publications including the two-volume A Book of South African Flowers. The genus Kensitia in the Aizoaceae was published in 1940 by German botanist Friedrich Karl Georg Fedde. This is a monotypic genus with Kensitia pillansii being the single taxon in the genus. (CRC World Dictionary of Plant Names)

kensitii: for Edward George Kensit (1879-1916), assistant in the Bolus Herbarium 1912-1915 and likely brother of Harriet Margaret Louisa Kensit (later Mrs. Frank Bolus) (1877-1970), commemorated with Lessertia kensitii which he collected in the Baakwu's River Valley near Port Elizabeth in 1914. (JSTOR)

kersii: for Lars Erik Kers (1931- ), Swedish botanist on staff at Bergius Botanic Garden in Stockholm, has made at least two collecting tours in southern Africa. He is commemorated with the former taxon Isoetes kersii, collected in 1963 in Namibia along the Angolan border and about 8 km west of Eunda, and now synonymized to I. schweinfurthii. (JSTOR)

kerstenii: for Otto Kersten (1839-1900), pioneer explorer and geographer of East Africa, chemist and plant collector commemorated with Lygodium kerstenii. His name is also on several other plant species which do not appear in southern Africa, at least one chameleon, seversal beetles, a spider, a wasp, and a dragonfly among other things. (Flora of Zimbabwe)

kerzneri: for Sol Kerzner (1935- ), South African hotel and gambling magnate of Jewish-Russian immigrant parents, founder of both of South Africa’s largest hotel groups. The taxon Brachystelma kerzneri was supposedly discovered on one of his resorts. (David Hollombe, pers. comm.)

kiaerii: probably for Dr. Frantz Casper Kiaer (Kiær) (1835-1893), Norwegian physician and historian who collected bryophytes from all over the world, author of Musci Madagascarienses. Material he collected forms part of the bryophyte herbarium at the Botanical Museum, the University of Oslo. The taxon in southern Africa with this name is Cephaloziella kiaerii, and is a bryophyte.

Kickxia: for Jean Kickx, Sr. (1775-1831), Belgian botanist, apothecary, professor of botany, pharmacy and minerology at a medical school in Brussels, and was the author of Flora bruxellensis, published in Brussels in 1812. Both his son and his grandson Jean Jacques Kickx (1842-1887) became professors of botany at the University of Ghent. W.P.U. Jackson suggests that the name also commemorates the son Jean Kickx, Jr. (1803-1864), Belgian botanist and malacologist, but I have no certain confirmation of that. He would have been only 24 at the time so this may or may not be correct. Kickxia Jr. described over 500 new taxa and was the author of Flore cryptogamique des environs de Louvain (Leuven) (1835), which contains 754 species, and Flore cryptogamique des Flandres (Cryptogamic Plants of Flanders), a work completed and published posthumously in 1867. The genus Kickxia in the Scrophulariaceae was published in 1827 by Belgian botanist and politician Barthélemy Charles Joseph Dumortier. (CRC World Dictionary of Plant Names)

Kiggelaria: for Francois (Franz) Kiggelaer (1648-1722), Dutch botanist, apothecary, traveller, plant collector, curator of Dutch plant collector Simon van Beaumont's garden and author of Horti Beaumontii Catalogus (1690), which listed some Cape plants, mostly succulents. He also collaborated with Dutch anatomist and professor of botany at the Hortus Botanicus of Amerstedam Frederik Ruysch (1638-1731), and worked on the first volume of Jan Commelijn’s Amstelodamensis Rariorum Horti Medici published in 1697, dealing with mainly the plants of the West Indies.The genus Kiggelaria in the Flacourtiaceae was published by Linnaeus in 1753. (CRC World Dictionary of Plant Names; W.P.U. Jackson; Wikipedia)

Killickia/killickii: for Donald Joseph Boomer Killick (1926- ), South African botanist on staff at the Botanical Research Institute, Fellow of the Linnean Society and President of the South Africa Biological Society, author of Flora of the Natal Drakensberg and The Flowering Plants of Africa. "He studied at the University of Natal obtaining a Ph.D in 1962. He worked for the Botanical Research institute from 1950, became Liaison officer at Kew 1954-1957, officer in charge of the Botanical Survey 1963-66 in charge of the Flora Research Team, returned to Kew as Liaison Officer 1969-71, and was promoted Assistant Director then Director of the Botanical Research Institute 1973. He became a Fellow of the Linnean Society in 1966 and was also President of the Biological Society. He is credited with having collected some 5,000 specimens mainly in the Drakensberg Mts." The genus Killickia in the Lamiaceae was published in 2008 by Christian Bräuchler, Günther Heubl and Anton Doroszenko. Killick was also commemorated with the taxa Carex killickii and Festuca killickii. (Etymological Dictionary of Grasses; Gunn & Codd; Hugh Clarke)

Kindbergia: for Nils Conrad Kindberg (1832-1910), Swedish bryologist, author of Catalogue of Canadian Plants. He obtained his Ph.D from Uppsala University (1857), became senior school teacher in nature science and mathematics in Linköping (1860-1910), made several bryological study and collecting trips to Germany, Switzerland, France, Spain and Italy, and later to North America. Between 1888-1910 he published over 50 papers relating to mosses of North America, many sent to him by John Macoun (1831-1920), a Canadian naturalist. Kindberg authored Species of European and Northamerican Bryineae (1896), Genera of European and Northamerican Bryineae (1897), and New Canadian Mosses (1889) (with Macoun). Many of his “new” species proved to be founded on insignificant variations of earlier described mosses. This moss genus Kindbergia in the Brachytheciaceae was published in 1982 by Polish bryologist Ryszard Ochyra. (Tropicos; Wikipedia)

kingesii: for Heinrich Kinges (1912- ), German botanist and plant collector. He collected Eragrostis kingesii and Eriocephalus kingesii in Namibia as well as the former species Pteronia kingesii, now synonymized to P. polygalifolia, and is commemorated with their names. (Etymological Dictionary of Grasses; JSTOR)

Kirkia/kirkiana: for Sir John Kirk (1832-1922), a famous Scottish explorer and a naturalist, physician, keen botanist, companion to David Livingstone, and British administrator in Zanzibar who later became an important figure in dismantling the eastern slave trade and and negotiating a lease of territory which led to the founding of British East Africa. He studied medicine at the University of Edinburgh (1847-1854), served with civil medical staff during the Crimean war, joined David Livingstone’s second expedition (1858) but returned to Britain in 1863 because of ill health. In 1866 he returned to Zanzibar and became consul-general and acting surgeon in 1873. He was very interested in the practical and pharmaceutical use of plants, wrote a revision of economically important East African palms and had a substantial collection of non-marine mollusks. The genus Kirkia in the Simaroubaceae was published in 1868 by Daniel Oliver. John Kirk was also commemorated with Tagia kirkiana and Justicia kirkiana. (PlantzAfrica; Wikipedia)

kirkii: for (1) Sir John Kirk (1832-1922), see above, commemorated with Huernia kirkii. Quoting from The Bulletin of Miscellaneous Information/Royal Botanic Gardens, Kew, 1922, "The following is a list of some of the plants from him [Dr. Kirk]..." and Huernia kirkii is on that list. (Gunn & Codd); (2) John William Carnegie Kirk (1878-1962), Scottish botanist and son of Sir John Kirk, soldier who rose to the rank of LtCol., served in the Anglo-Boer War 1899-1902, stationed at Komatipoort area, later in East Africa and in WWI. Gunn & Codd and some other websites say J.W.C. Kirk is commemorated with Huernia kirkii, but this is not correct. He did however collect Dalechampia kirkii for which he is commemorated. (Gunn & Codd; JSTOR); (3) Thomas Kirk (1828-1898), British botanist who became a New Zealander and an authority on taxonomy, commemorated with Searsia kirkii. (Wikipedia)

kirschsteineanus: for Egon Friedrich Kirschstein, German geologist who worked in Central Africa. He came to Africa with the expedition of Duke Adolf Friedrich of Mecklenburg (1907-08). He either stayed and worked until the mid-20th Century in Central Africa, or returned at some later date, and apparently was married to a black woman with whom he had a number of children. The taxon in southern Africa that has this epithet is the former Senecio kirschsteineanus, now synonymized to Cineraria deltoidea. This taxon is variously spelled as kirsteineanus or kirschsteinianus, and was published in 1911 by German botanist Reinhold Conrad Muschler in Wissenschaftliche Ergebnisse der Deutschen Zentral-Afrika-Expedition 1907-1908 (Scientific results of the German Central African Expedition 1907-1908). (David Hollombe, pers. comm.; On The River by Hermann Schulz)

kirstenii: for (1) Kirsten Louw (1979-2005), a passionate and enthusiastic birder and naturalist, who discovered a new species of bulb, a striking yellow-flowered Albuca, near his family’s house on the Breede river. Kirsten died tragically at the age of 26 while completing his Ph.D. at the University of Cape Town. It is recorded in his obituary “It is entirely fair to say that at the time of his death, there were only a small handful of people with his combined expertise on the Cape’s flora and fauna.” He left his name on the Albuca. (Hugh Clarke, pers. comm.; Biodiversity Explorer); (2) Gerhard Petrus Kotze ("Kallie") Kirsten (1932-2000), South African amateur botanist and plant collector, journalist and sports reporter for Die Burger, archivist at financial services company SANLAM Limited, co-author of Ericas of South Africa with Dolf Schumann, collector of much Erica material, commemorated with Erica kirstenii. (StellenboschWriters.com; Ted Oliver, pers. comm.)

klainei: for Révérand Père Théophile-Joseph Klaine (1842-1911), sometimes listed as R.P. Klaine or just P. Klaine, French Catholic missionary and plant collector in Cameroon, Gabon and the Congo.

He collected one of the largest private nature collections of the 18th century and he founded the world famous Danzig botanical garden. The genus Kleinia in the Asteraceae was published in 1754 by Scottish botanist Philip Miller. (CRC World Dictionary of Plant Names, Wikipedia)

Klenzea: I have no information about the derivation of this genus name in the Asteraceae, which was published in 1840 by German botanist Carl Heinrich 'Bipontinus' Schultz. Hugh Clarke has proposed the possibility of Leo von Klenze (Franz Karl Leopold von Klenze) (1784-1864), German architect, painter, draughtsman, art collector and writer, but I can find no confirmation of this and no indication that he had any connection with botany, although he could have been a friend of Schultz. Hugh adds that he "became court architect to Jérôme Bonaparte, King of Westphallia (1808-1813), and to the Bavarian king Ludgwig I, from 1816. He designed, inter alia, many neoclassical buildings – temples, museums, galleries – in Munich and Regensberg, submitted plans for the restoration of the Acropolis in Athens, Greece, and designed the ‘New Hermitage’ public museum in Saint Petersburg, Russia. Klenze’s collection of contemporary German painters is now housed in the Neue Pinakothek Museum in Munich." The genus Klenzea in the Asteraceae was published in 1843 by German botanist Wilhelm Gerhard Walpers based on an initial publication by Carl Heinrich 'Bipontinus" Schultz. (Hugh Clarke)

Klingia: for Erich Kling (1854-1892), traveller, explorer, naturalist in West Africa, Army officer, and plant collector, "possibly working for the German East Africa Company, in search of treatises of friendship and protection with local tribes as part of the Imperial Germany's colonial efforts. In 1889, Kling went to West Africa, specifically to Togo, bordered by Ghana to the west, Benin to the east and Burkina Faso to the north. He went to Dapaon in Togo, Borgou, one of the twelve ‘departments’ of Benin, Sousou in Guinea, and Tchaoudjo in the central region of Togo, but was turned back because of the hostile population and African resistance. He fell ill several times during the expedition and died shortly after he returned to Germany." The genus Klingia in the Amaryllidaceae was published by German-born South African botanist Selmar Schönland in 1919. Klingia is a monotypic genus with only a single species, Klingia namaquensis. (CRC World Dictionary of Plant Names; Hugh Clarke)

klotzschianus/klotzschii: for Johann Friedrich Klotzsch (1805-1860), German pharmacist and botanist, curator of the royal herbarium at Berlin, collected in Hungary, Austria, Germany, the U.K. and Peru. His major work was in the field of mycology. The species Blaeria klotzschii was first published in 1925 and then published as Erica klotzschii in 1993, and this epithet commemorates J.F. Klotzsch, and also very likely the former taxon Simocheilus klotzschianus (now Erica inaequalis). He also published the names of at least twenty-five ericaceous genera, and is commemorated with the genus Klotzschia in the Apiaceae which is not in southern Africa. (Wikipedia; Ted Oliver, pers. comm.)

klugei: for Johan Paul Kluge (1947-1998), botanist, plant collector, Forest Research Officer stationed at Witklip near White River, and Curator of the Lowveld Botanical Garden, commemorated with Disa klugei. (Gunn & Codd; JSTOR; Yearbook of SA Orchids of 1999)

Knightia: for Thomas Andrew Knight (1759–1838), English botanist, vegetable physiologist and horticulturalist. His practical, large scale research on the 4,000 ha of land he inherited involved physiological experiments on plants aimed at improving fruit and vegetable qualities and preventing diseases among them. He raised new varieties of apples, cherries, strawberries, plums, nectarines, pears, potatoes, cabbages, and peas, many of which bear his name. His major work was Treatise on the Culture of the Apple and Pear and on the Manufacture of Cider and Perry (1797), but he wrote over 100 papers. He was President of the London (later 'Royal') Horticultural Society, founded in 1804, from 1811 to 1838 and elected a fellow of the Royal Society (1805), which awarded him the Copley medal in 1806. He became a Fellow of the Linnean Society in 1807. The genus Knightia in the Proteaceae was published in 1810 by British botanist Robert Brown. (Hugh Clarke)

knightiana: for Charles Knight (1808-1891 or 1818-1895), Fellow of the Linnean Society who specialized in bryophytes, fungi and lichens, commemorated with Pyrenula knightiana and the former lichen taxon Ramalina knightiana, now synonymized to Ramalina inflata. (David Hollombe, pers. comm.; JSTOR; Dictionary of British and Irish Botanists and Horticulturists)

knightii: for Joseph Knight (1777-1855), British nurseryman, author of On the Cultivation of the Plants Belonging to the Natural Order of the Proteaceae (1809), commemorated with Serruria knightii, now synonymized to S. fasciflora. He was an associate of George Hibbert, a keen amateur botanist who established a substantial private botanical garden at Clapham and employed Knight as head gardener. They shared a passion for Proteaceae, which were considered very fashionable at the time. He acquired Hibbert's collection in 1837. (Dictionary of British and Irish Botanists and Horticulturists; JSTOR)

Kniphofia: for Johann Hieronymus Kniphof (1704-1763), German physician, lecturer, professor, Dean of the Medical Faculty, finally Rector of the University of Erfurt, author of a folio of nature-printed illustrations of plants in 1733, followed by significantly expanded editions in 1747 and 1758. His book Botanica in Originali seu herbarium vivum was the first significant work to follow Linnaeus’s nomenclature. The genus Kniphofia in the Xanthorrhoeaceae (formerly Asphodelaceae) was published in 1794 by German botanist Conrad Moench. (PlantzAfrica; Wikipedia)

knobelii: for (1) Johann Christian Knobel (1879-?), South African missionary, naturalist, trader and hunter, collector of succulent plants, who collected in South Africa with his younger brother Jurgens C.J. Knobel, commemorated with Orbea knobelii (Gunn & Codd); (2) Jurgens C.J. Knobel (1881-?), Director of Prisons in Pretoria 1927-1932, commemorated with Euphorbia knobelii. (Etymological Dictionary of Succulent Plant Names; Gunn & Codd)

Knowltonia: for Thomas Knowlton (1691-1781), an English horticulturist, botanist and Curator of the Botanic Garden at Eltham, well known in his lifetime as a botanist and gardener with a special interest in nature, wildflowers and hothouse exotics. His life story, No Ordinary Gardener: Thomas Knowlton, was written by Blanche Henrey (British museum, 1896). He designed many gardens for the wealthy and collected and grew plants from around the world. The genus Knowltonia in the Ranunculaceae was published in 1796 by British botanist Richard Anthony Salisbury formerly known as Richard Markham. (CRC World Dictionary of Plant Names; Wikipedia)

knox-daviesii: for Charles Norman Knox-Davies (1879-1959), South African attorney and plant collector, uncle of plant pathologist Peter Sidney Knox-Davies, commemorated with Tulbaghia daviesii (now T. simmleri), collected in 1930, and Delosperma knox-daviesii, collected by Knox-Davies near Johannesburg in 1934. (Etymological Dictionary of Succulent Plant Names; JSTOR)

knuthii: there is much confusion regarding the derivation of Euphorbia knuthii. Elsa Pooley says this epithet commemorates Professor Paul Erich Otto Wilhelm Knuth (1854-1900), German botanist and ecologist, author of a classic work on pollination, but Wikipedia says that it is named for German botanist and taxonomist Reinhard Gustav Paul Knuth (1874-1957) who worked for more than 50 years at the Botanical Museum in Berlin-Dahlem, destroyed by bombing and fire on the nights of 1 and 2 March, 1943, resulting in the loss of his own extensive herbarium collection of some 26,000 specimens. The website mentioned below (CactusPro) says that it is named for German botanist Frederik Marcus Knuth (1904-1970). This last is clearly disproved by the fact that the taxon was published in 1904 by Ferdinand Albin Pax, and in any case Frederick Marcus Knuth was Danish, not German. However, Pax and Reinhard Gustav Paul Knuth collaborated on the Primulaceae for Adolph Engler's Das Pflanzenreich, published in 1905, so that would suggest a connection that gives credence to the Wikipedia derivation. (Elsa Pooley; Encyclopedia of Succulents at CactusPro.com)

Kobresia: for Paul von Kobres (1747-1823), Austrian botanist, plant collector, patron and promoter of botany. He was the owner of a rich natural history collection and library, which was purchased in 1811 for the Bavarian Academy of Sciences.

Kochia: for Wilhelm Daniel Joseph Koch (1771-1849), German botanist and physician, professor of botany at Erlangen where he was director of its Botanical Gardens. Among his publications, he wrote a treatise on German and Swiss flora titled Synopsis florae germanicae and helveticae (1835-37). In 1833, he was elected a foreign member of the Royal Swedish Academy of Sciences. The genus Kochia in the Chenopodiaceae (CRC World Dictionary of Plant Names)

koelemanii: for Arthur Koeleman (1915-1994), South African schoolteacher and horticulturist, succulent enthusiast and pioneer breeder of aloes, founder of the Succulent Society of South Africa, commemorated with the former taxon Lithops koelemanii which is now L. aucampiae. (David Hollombe, pers. comm.)

Koeleria: for Georg Ludwig (Georgius Ludovicius) Koeler (1765-1807), German botanist and physician, professor of botany at Mainz, pharmacologist and writer on grasses. His book Descriptio graminum in Gallia et Germania (1802) described the grasses of Germany and France. The genus Koeleria in the Poaceae was published in 1805 by South African mycologist Christiaan Hendrik Persoon. (CRC World Dictionary of Plant Names)

koelmaniorum: for Mr. and Mrs. T.H.C. Koelman of Groblersdal, Mpumalanga, according to the Penrock Seeds and Plants Newsletter, Sep and Oct 2008, and the website "All You Wanted To Know About Haworthias." The book Succulent Flora of Southern Africa by Doreen Court says that Haworthia koelmaniorum was discovered in 1963 by Marius Koelman. I don't know how to reconcile these two derivations. The taxon was published in 1967 by Anna Amelia Obermeyer and David Spencer Hardy. (David Hollombe, pers. comm.)

koenigii: for Johann Gerhard König (Koenig) (1728-1785), a Polish missionary, botanist and physician, and a private pupil of Carl Linnaeus, commemorated with the former taxon Sclerochaetium koenigii, now Tetraria bromoides. In addition to South Africa, he also collected plants in Sri Lanka, India, Malaysia and Thailand, and is commemorated with the genus Koenigia that does not appear in South Africa. (Gunn & Codd)

koflerae: for Dr. Lucie Kofler (1910-2004), French botanist who was on staff at the University of Grenoble, plant collector in Lesotho, commemorated with Peltula koflerae. This person and the person in the next entry could be the same person, or at the very least related. (Gunn & Codd)

kofleri: for Dr. C. Kofler (fl. 1966), commemorated with Delosperma kofleri. This person and the person in the previous entry could be the same person, or at the very least related. (Etymological Dictionary of Succulent Plant Names; JSTOR)

Kohautia: for Francisci (Franz) Kohaut (?-1822), Czech inventor, plant collector and gardener, accompanied Franz Wilhelm Sieber, a Czech naturalist and explorer, to Crete, Egypt and Palestine, 1816-1818, and afterwards was also contracted to collect specimens in Martinique 1819-1821. Kohaut died in Senegal, 1822, while on an expedition. The genus Kohautia in the Rubiaceae was published in 1829 by German botanists Ludolf Karl Adelbert von Chamisso and Diederich Franz Leonhard von Schlechtendal. (Wikipedia)

Kohleria: for Johann Michael Kohler (1810/1816-c.1884), Swiss teacher (lecturer, professor) of natural history in Zurich, presumably the author of Landwirthschaftliche Ortsbeschreibungen aus dem Kanton Zurich (Land management of the Canton of Zurich) (1853) and Aufzählung und Beschreibung der wichtigsten Kern-Obstsorten (1869) (Enumeration and description of the main core of fruit in the canton of Zurich). I found a post online from his great great great granddaughter that says he "was deeply involved in the botanical gardens and horticulture. He edited horticultural journals for a number of years. I believe he was born in the early 1800s (perhaps 1810-1816). Later on, he was published on new techiques in wine making with works such as Der Weinstock und Der Wein (The Vine and the Wine), and Neueste Fortschritte in der Weinbereitung, als Ergänzung (1871) (Recent advances in winemaking). He had a home with "beautiful" gardens on the lake. He died around 1884. His wife was Elizabeth "Lisette" Irminger (her father might have been a doctor) and she came to America around 1860 with her 1 year old son Paulus (known as Paul). They lived in Brooklyn, New York City. I don't know if the wife ever went back but the son stayed here and died in the early 1920s." (Thanks to Deborah Woolley for that information.) The genus Kohleria in the Gesneriaceae was published in 1848 by German horticulturist and botanist Eduard August von Regel. (CRC World Dictionary of Plant Names)

Kohlrauschia: for Henriette Kohlrausch (née Eichmann) (1781-1841), German botanist and wife of Dr. Heinrich Kohlrausch (1780-1867), educator and historian. The genus Kohlrauschia in the Caryophyllaceae was published by Carl (Karl) Sigismund Kunth in 1838. (David Hollombe, pers. comm.)

He was a member of the Cape Town Mountain Club and made friends with such notable botanists as Bolus, MacOwan, Marloth, Pole Evans and Alice Pegler. He had a herbarium of some 5000 sheets. See also elliottiana. He is commemorated with Lichtensteinia kolbeana (now synonymized to L. interrupta), Disparago kolbei and Jacobsenia kolbei. (Gunn & Codd; JSTOR)

Kolleria: for General Baron Franz von Koller (1767-1826), Austrian military officer (Colonel 1805, General 1809, Field Marshall 1813 - to become Commander-in-Chief of the Austrian Army in 1820) who accompanied Napoleon to Elbe, accompanied the Czar, the King of Prussia and the Archdukes Johann and Ludwig to Britain, and then went to St. Petersburg to invite the Czar to the Congress of Vienna. He was honored with aristocracy and made a Baron and received numerous honours including the Aspro Cross Maria Theresa award for bravery. During his career he also served as Governor of Bohemia and Austrian ambassador in London. Koller left a huge collection of antiques, especially large vases from Pompeii, now in the Berlin Museum. He died of typhus.The genus Kolleria in the Aizoaceae was published in 1830 by Bohemian botanist Carl Bořivog Presl, who described him as a "lover and promoter of science." (David Hollombe, pers. comm.; Symbolae Botanicae: Descriptiones et Icones Plantarum Novarum Aut Minus Cognitarum by Carl Bořivog Presl)

Kosteletzkya: for Vincenz Franz Kosteletzky (1801-1887), Czech botanist and physician, professor of botany, and Director of the Botanical Garden Smíchov (Prague). in 1836 published a monumental 2237-page work on medicinal plants entitled Allgemeine medizinisch-Pharmazeutische Flora (General Medical and Pharmaceutical Flora). He was also author of Clavis analytica in Florum Bohemiae phanerogamicam (1824) and Index plantarum horti caesarii regii botanici pragensis (1844). The genus Kosteletzkya in the Malvaceae genus was published in 1835 by Bohemian botanist Carl Bořivog Presl. (CRC World Dictionary of Plant Names)

Kotschya/kotschyana/kotschyi: for Carl (Karl) Georg Theodor Kotschy (1813-1866), Austrian botanist, traveller and plant collector, botanical explorer in the Orient, and discoverer of hundreds of new species. Over the period 1835-1862 he took part in numerous expeditions to Syria, Egypt, Sudan, Cyprus, S. Iran and Zagros Mts, N. Tehran, S.Turkey, Palestine, Lebanon, Kurdistan, and N. Syria, during which time he became an assistant (1847) and then Curator (1852) of the Herbarium of the Vienna Natural History Museum.

Antoine (1855). The genus Kotschya in the Fabaceae was published by Austrian botanist Stephan Friedrich Ladislaus Endlicher in 1839. He was also commemorated with the former taxa Peristrophe kotschyana (now synonymized to P. decorticans), Crossopteryx kotschyana (C. febrifuga), Leiocarya kotschyana (Trichodesma zeylanicum), Heteranthera kotschyana (H. callifolia), Conyza kotschyi (Pentanema indicum) and Commelina kotschyi (C. imberbis). (CRC World Dictionary of Plant Names; JSTOR)

kotzei: for P.C. Kotze (fl. 1911-1937), S.A. Department of Forestry, who collected in various parts of South Africa. He collected Xylotheca kotzei in South Africa in 1921 and is commemorated with its name. (JSTOR; Gunn & Codd)

He is commemorated with Habenaria kraenzliniana. His name is also on the orchid genus Kraenzlinella which does not appear in southern Africa.

kraeuseliana: for Richard Oswald Karl Kräusel (Kraeusel) (1890-1966), German paleobotanist, author of Die Flora des böhmischen Mitteldevons, one of the world's eminent paleobotanists, studied under the German botanist Ferdinand Albin Pax, travelled widely and did research in Southeast Asia, South America and South-West Africa, published over 250 papers, lecturer and professor at the University of Frankfurt, Director of the Division of Botany-Paleobotany at Senckenberg Natural History Museum. "During the Second World War, his collections were moved for safekeeping to a nearby castle, which was destroyed during the raids on Frankfurt; all of the type material, and many other valuable fossils from his collection, were lost." He is commemorated with Commiphora kraeuseliana. (CRC World Dictionary of Plant Names; JSTOR; Gunn & Codd)

krapohliana: for Heinrich Johannes Christian Krapohl (1859-1949?), South African botanist, land surveyor, wagon-maker, date planter and succulent plant enthusiast and collector in the Republic of South Africa who first collected Aloe krapohliana. He retired to Abbasas on the south bank of the Orange River where he lived for nearly thirty years. He sent specimens to botanist Hermann Wilhelm Rudolf Marloth, who later described Aloe Krapohliana from plants growing in Krapohl's garden in Cape Town. (Etymological Dictionary of Succulent Plant Names; Gunn & Codd; PlantzAfrica)

krausei: probably for Kurt Krause (1883-1963), German botanist. The taxon in southern Africa with this name was the former taxon Commiphora krausei, now synonymized to C. mollis.

Krauseola: named for Ernst Hans Ludwig Krause (1859-1942), German botanist and physician, batologist (person who studies brambles), and plant collector in West Africa. The JSTOR website says he was a cryptogamist. They write: “plant collector in Europe (France, Germany), tropical Africa (Liberia), West Indies (Barbados, Dominica, Haiti, Saint Vincent and the Grenadines, Virgin Islands), and USA (c. 1884-1930). His original general herbarium was deposited at the Berlin-Dahlem Botanic Garden and Botanical Museum (1929), his bryophyte herbarium of some 2,000 specimens (1935) and his fungal herbarium (1941). Part of the material is extant, though the remainder was destroyed during the Second World War.” He was a professor of botany at Strasburg (1904), served in the Naval Medical Corps in Kiel and on the battleship Gneisenau, and became a surgeon in Saarlouis and Rostock after WWI. He authored Flora of Rostock and the neighborhood (1879), Mecklenburg Flora (1893), Rostock Moss Flora (1921-1922) and other works.The genus Krauseola in the Caryophyllaceae was published in 1934 by Ferdinand Albin Pax and Käthe Hoffman.(CRC World Dictionary of Plant Names)

Kraussia/kraussiana/kraussianum/kraussianus/kraussii: for Christian Ferdinand Friedrich von Krausse (1812-1890), German botanist and traveller, professor and Director of the Natural History Museum at Stuttgart, zoologist and plant collector in South Africa, associated with Stuttgart Natural History Museum. He also studied minerology and chemistry. He came to the Cape in 1838, and did much plant collecting in Natal in 1839 and 1840. He also mollusks and crustaceans, and made a general study of the geology, flora and fauna. From late 1838 to mid-June 1839, he explored the areas between Cape Town to Port Elizabeth, and from mid-June to January 1840 the bush and seashore around the Congella river, also Pietermaritzburg. On 22 April 1840, he left to join the Natural History Museum, Stuttgart, becoming its director in 1956. He wrote Die suidafrikanischen Crusaceen (1843) and Die suidafrikanischen Mollusken (1848).The genus Kraussia in the Rubiaceae was published in 1844 by Carl Heinrich Schultz.

(Hugh Clarke, pers. comm.; Trees and Shrubs of Mpumalanga and Kruger National Park; JSTOR)

Krebsia/krebsiana/krebsianum/krebsianus/krebsii: for Georg Ludwig Engelhard Krebs (1792-1844), a German emigrant to South Africa, apothecary, naturalist and chemist, botanist and botanical collector, associate of Karl Heinrich Bergius. He came to the Cape in 1817 on a four year contract to the apothecaries, Pallas & Poleman. From 1820 to 1840 Krebs collected, mainly in the Eastern Cape, for the Berlin Natural History Museum on behalf of the Royal Prussian Department of Education and Medicine, sending them fourteen huge consignments. His 12th consignment consisted of 7,245 dried plant specimens, 900 birds, 7,000 insects, a rhinoceros and elephant, a quagga (now extinct), and a complete Bushman (Khoi San) pickled in a barrel of wine. In 1844, he was recommended for the King of Prussia’s Order of the Red Eagle for meritorious contributions to science but died before it could be awarded. He made numerous botanical expeditions to Madagascar, Mauritania, and Réunion, during which he collected numerous specimens and materials also for the Museum of Natural History in Berlin. The genus Krebsia in the Apocynaceae (formerly Asclepiadaceae) was published by British botanist William Henry Harvey in 1868. (CRC World Dictionary of Plant Names; Hugh Clarke)

kreugeri: the taxon Pittosporum kruegeri was collected by F. Wilms in 1897 in Lydenburg District of South Africa which includes Kruger National Park, so this is just a guess, but I suspect that this is where this epithet is derived from and not from someone's name. JSTOR has records of two plant collectors named Krueger but neither of them collected in South Africa. In addition there are three Krugers listed who did collect in South Africa, I. Kruger and P.R. Kruger with no dates, and Frederick Kruger (see krugeri). (JSTOR)

krigeae: for a Miss A.M. Krige who collected Erica krigeae in South Africa in 1908. She also collected Erica pyrantha, identified from samples she bought fresh in the streets of Cape Town. (JSTOR; Icones orchidearum austro-africanum extra-tropicarum; Ted Oliver, pers. comm.)

krigei: for a certain J.D. Krige of Stellenbosch, who collected Nerine krigei in 1932 in the Transvaal. The taxon was published by Winsom Fanny Barker in 1932. (JSTOR; Mainly Amaryllids Garden)

kritzingeri: for Kobus Kritzinger (1983-2005) of the Cape Department of Nature and Environmental Conservation according to Eggli & Newton, although a JSTOR specimen record indicates it was collected by a J.J. Kritzinger (1953- ) in 1981. The CRC World Dictionary of Plant Names says: "the species was named after Mr. Kobus Kritzinger of the Cape Department of Nature Conservation, one of the collectors of the species in September 1981." So both of these names probably refer to the same person. Ernst J. Van Jaarsveld who published the name was the other collector. The species in question is Tylecodon kritzingeri. (CRC World Dictionary of Plant Names; Etmological Dictionary of Succulent Plant Names; JSTOR)

krookianum/krookii: for P. Krook (fl. 1894-1905), Swedish botanist and plant collector, commemorated with Chlorophytum krookianum, Indigofera krookii, Lobelia krookii (now L. erinus), Plectranthus krookii (P. grallatus), Pimpinella krookii, Kniphofia krookii (K. parviflora), Heteromma krookii, Euryops krookii (E. tysonii), Nidorella krookii (N. resedifolia), Helichrysum krookii, and Chascanum krookii, all of which he collected. (Gunn & Codd; JSTOR)

Kroswia: for Hildur Krog (1922- ), Norwegian lichenologist and collector of fungi and lichens, Curator of the Botanical Museum of Oslo, professor at the University of Oslo, and Thomas Douglas Victor ("Dougal") Swinscow (1917-1992), on staff at the British Medical Journal, founder of the British Lichen Society and its journal The Lichenologist, co-author with Dr. Krog of The Macrolichens of East Africa. The lichen genus Kroswia in the Pannariaceae was published in 2002 by Norwegian botanist Per Jørgensen. in honor of these two scientists who collected together in Kenya in 1972. (David Hollombe, pers. comm.; The Lichenologist Vol. 34/4 2002; JSTOR; Wikipedia)

krugeri: for Frederick John Kruger (1944- ), South African forest ecologist, MSc Stellenbosch Univ. 1974, Forest Research Officer, Jonkershoek Forest Research Station near Stellenbosch from 1966, commemorated with Erica krugeri. (Gunn & Codd; Brian Bates Eponomy)

kulsii: possibly for Wolfgang Kuls (1920-2002), plant collector, author of Probleme der Bevölkerungs-geographie and Geographie Ais Sozialwissenschaft. The taxon in southern Africa with this epithet is the former Aspidoglossum kulsii, now synonymized to A. masaicum).

kuneneana: there are two taxa in southern Africa with this epithet, Ceraria kuneneana and Commiphora kuneneana, but I have not been able to find any information as to its derivation, or even any indication that it is in fact named after a person. JSTOR has no records of any collector named Kunen, nor does Tropicos or the Harvard University Herbarium database of botanists and collectors. Further research has turned up a region called Kunene named after the Kunene River which forms the international boundary between Namibia and Angola, and it is in this region that Ceraria kuneneana was found, so this is the derivation of that epithet, and I believe this relates to the other taxon as well. ("Ceraria kuneneana: a new species from the Kaokoveld, Namibia" by W. Swanepoel, H.G.W.J. Schweickerdt Herbarium, Department of Botany, University of Pretoria)

kunhardtii: for Chris Kunhardt (c.1929-1990), avid amateur botanist, Streptocarpus enthusiast, and plant name author who discovered Streptocarpus kunhardtii. (Novon Vol. 13, No. 2; "Two New Species of Streptocarpus from South Africa" by T.J. Edwards, School of Botany and Zoology, University of Natal)

kunkelianum: for Günther W. H. Kunkel (1928-2007), German botanist, naturalist and explorer. He was the author of 70 books and over 1000 articles, and made several trips to South America, Africa and tropical parts of the Middle East. He is commemorated with Androcymbium kunkelianum and Colchicum kunkelianum. (David Hollombe, pers. comm.)

kunthiana/kunthianum/kunthii: for Karl (Carl) Sigismund Kunth (1788-1850), German botanist, one of the first to study and categorize plants from the Americas and co-author of Nova Genera et Species Plantarum in 7 vols. (1815-1825), assistant to Alexander von Humboldt in Paris from 1813 to 1819, professor of botany at the University of Berlin as well as Vice President of the botanical garden. He also described plants from South Africa. Although I can't confirm that any of these are named for him, it is likely that they are: Microchloa kunthii, Isolepis kunthiana (now synonymized to Isolepis incomtula), Kobresia kunthiana (Schoenoxiphium sparteum), Restio kunthii (Ischyrolepis triflora), Sympieza kunthii (Erica benthamiana) and Verrucaria kunthii (Pyrenula mammilana). (Etymological Dictionary of Grasses; Wikipedia)

kuntzeanus/kuntzei: for Carl Ernst Otto Kuntze (1843-1907), German botanist, author of the widely rejected Revisio Generum Plantarum (1891), which was the result of his analysis of some 7,700 specimens he collected on an around the world voyage 1874 to 1876. In 1886 he was in the Russian Near East, then in the Canary Islands from 1887 to 1888, and the results of these journeys were incorporated into the Revisio as well. In the early 1890's he visited most of the South American countries and in 1894 the southern African countries. Wikipedia says further that "His revolutionary ideas about botanic nomenclature created a conflict at the 2nd Congress of Botany, as a result of which the doors of the academic world were closed to him." The taxon in southern Africa with the epithet kuntzeanus is the former Plectranthus kuntzeanus, now synonymized to P. strigosus. He also collected and almost certainly is commemorated with the taxa Brownanthus kuntzei, Anisothrix kuntzei, Berkheyopsis kuntzei (now synonymized to Hirpicium echinus), Berkheya kuntzei (B. discolor), Senecio kuntzei (S. glaberrimus), Hertia kuntzei (Senecio lydenburgensis), Nesaea kuntzei (N. schinzii), and Heliotropium kuntzei (H. lineare). (Wikipedia)

Kunzea/kunzei: for Gustav Kunze (1793-1851), a German professor of zoology, botanist and entomologist at Leipzig University, director of the Botanical Gardens in Leipzig. He studied medicine at the University of Leipzig and earned an M.D. but may not have ever practiced medicine. He was appointed Director of the Botanical Gardens in Leipzig in 1837 and became a full professor in 1845. He collected in America, specifically in Louisiana in the early 1800's. The taxon in southern Africa with this epithet is Cheilanthes kunzei. His specialties were orchids, ferns, and microscopic fungi. He was elected a foreign member of the Royal Swedish Academy of Sciences in 1851. He published a number of monographs on beetles, fungi and lichen. He published, with J. K. Schmidt, Mykologische Hefte (Mycological Notebooks) in 2 vols. (1817 - 1823). In addition to Cheilanthes, his name is on other ferns in genera Thelypteris, Adiantum, Tectaria, Polybotrya, Botryothallus, Aspidium, Lindsaea, Gymnogramma and Cheilosoria. He is also honored with the genus Kunzea in the Myrtaceae published in 1828 by German botanist Heinrich Gottlieb Ludwig Reichenbach. (Wikipedia; The Ferns of Florda; CRC World Dictionary of Plant Names)

kurokawae: for Dr. Syo Kurokawa (1926-2010), Japanese lichenologist, senior curator at the Division of Cryptogams, National Science Museum, Tokyo and then Director of Botany, later Director of the Tsukuba Botanical Garden, a part of the National Science Museum, after his retirement from the National Science Museum. He has served as director of the Botanical Garden of Toyama, published numerous papers and rendered significant contributions to the taxonomy of Anaptychia and Parmelia, built up a lichen herbarium at the National Science Museum which is now among the largest and best preserved herbaria in the world, and was a winner of the Acharius Medal of the International Association of Lichenology. The taxon in southern Africa with this name is the former Parmelia kurokawae and Xanthoparmelia kurokawae, synonymized now to Xanthoparmelia lavicola. (The Lichenologist 43(3):191-192, 2011)

kurtdinteri: See Dintera/Dinteracanthus/Dinteranthus/dinteri/dinteriana.

Kurzia: for Wilhelm Sulpiz Kurz (1834-1878), German botanist, plant collector, Director of the Botanical Garden of Bogor, West Java province, and also Kolkatta (formerly Calcutta), and member of the Asiatic Society of Bengal. Hugh Clarke provides the following: "He worked in and explored the flora of India, Indonesia, Burma, Malaya, and Singapore. His publications include Forest Flora of British Burma in 2. vols (1877), Report on the Vegetation of the Andaman Islands (1870), Preliminary Report on the Forest and other Vegetation of Pegu (1875), and Bamboo and Its Use... (1876). His knowledge of trees seems extensive. One report states "In Lower Burma alone the enumeration of the trees made by Sulpiz Kurz in his Forest Flora of British Burma (1877) includes some 1500 species.”" JSTOR states that when he joined the medical services of the Dutch East Indies Army in 1856, he went by the more Dutch-sounding name Johann Amann. He also wrote articles in the Journal of the Asiatic Society of Bengal and the Journal of Botany. The genus Kurzia in the Moraceae was published in 1888 by George King. (JSTOR; Hugh Clarke)

Kyllinga: for Peder Lauridsen Kylling (c.1640-1696), Danish botanist, apothecary and author of Viridarium danicum (1688) (The Danish Garden), which accounts for about 1,100 species of plants native to Denmark, mainly in Zealand, Justland and Slesvig. It is alleged that he was working on an even larger edition but this book was not published. He studied theology at the University of Copenhagen and briefly served as a parish minister, before withdrawing from this profession to study botany.The genus Kyllinga in the Cyperaceae was published by Danish botanist-physician and student of Linnaeus Christen Friis Rottbøll in 1773.(CRC World Dictionary of Plant Names; Wikipedia)
