Cailliea: for Rene Caillie, French explorer (1799-1838), botanist, plant collector, the first European to return alive from the town of Timbuktu, author of Travels through Central Africa to Timbuctoo; and across the Great Desert, to Morocco (1824-1828). The genus Cailliea was published in 1833 by French botanists Jean Baptiste Antoine Guillemin and George Samuel Perrottet. (CRC World Dictionary of Plant Names; Wikipedia; David Hollombe, pers. comm.)

Calandrinia: for Jean Louis Calandrini (1703-1758), Swiss botanist, traveller and professor of mathematics and philosophy at Geneva, wrote on such subjects as the aurora borealis, comets, the effects of lightning, and flat and spherical trigonometry. This genus was published in 1823 by German botanist Karl Sigismund Kunth. (CRC World Dictionary of Plant Names; Wikipedia)

Caldesia: for Ludovico Caldesi (1822-1884), Italian botanist, politician, mycologist, naturalist, and member of Parliament. He was a student of the Italian botanists Filippo Parlatore and Giuseppe De Notaris, and was the author of Florae Faventinae Tentamen. The genus was published in 1860 by Italian botanist Filippo Parlatore. (CRC World Dictionary of Plant Names)

Calpurnia: after Calpurnius, Roman 1st century AD poet, whose full name was Titus Calpurnius Siculus. The genus was published in 1836 by German botanist Ernst Heinrich Friedrich Meyer. (CRC World Dictionary of Plant Names)

cambouei: the only possible name I can come up with here is the Rév. Père Paul Camboué (1849-1929) on the JSTOR list of plant collectors who collected on Madagascar. He was a French-born Jesuit who received a legal training, served in the War of 1870, and went to Madagascar in 1882. He became a member of the Malagasy Academy and was additionally a correspondent member of the Académie des Sciences, in Paris. He was interested in a great number of subjects, but concentrated mainly on natural history and specializing on the invertebrates, butterflies, beetles, ants, spiders and other insects. He collected plants with the Rév. Père Victor S.J. Montaut. The taxon in southern Africa with this specific epithet is Campylopus cambouei. (Dictionary of African Christian Biography)

cameronii: for Kenneth John Cameron (1862-1917) who collected in South Africa and was a Scottish planter at Ntondwe in Nyasaland, Malawi, for the African Lakes Corporation. Stereochlaena cameronii was collected by K.J. Cameron in Malawi in 1899 and Erica cameronii was collected by a K. Cameron in 1913, so those are presumably named after him. There was an Aloe cameronii (not in southern Africa) which he discovered and sent to Kew Gardens in 1854, and there is also a Tulbaghia cameronii that might honor him as well. He died on active service with the South African Volunteers in WWI. (Etymological Dictionary of Succulent Plant Names)

camperi: for Manfredo Camperio (1826-1899), Italian-born resident of Eritrea, founder of the travel journal L’Esploratore. George August Schweinfurth published the name Aloe camperi in 1894 for his friend Manfredo Camperio based on the type material collected at 4600' near Ghinda in Eritrea. (Etymological Dictionary of Succulent Plant Names; Aloes and Lilies of Ethiopia and Eritrea)

candolleana/candolleanum/candolleanus/candollei:  for Augustin Pyramus de Candolle (1778-1841), Pro-
fessor of Botany in Geneva, author of many botanical works such as Théorie élémentaire de la botanique (1813), Synopsis plantarum in flora Gallica descriptarum (1806), Plantarum historia succulentarum (1799 in 4 vols.), and Prodromus Systematis Naturalis Regni Vegetabilis. He was a greatly significant figure in the world of botany. His concept of nature at war with itself was an influence on Darwin who studied his natural system of classification. He had a son Alphonse Louis Pierre Pyrame de Candolle (1806-1893) and a grandson Anne Casimir Pyrame de Candolle (1836-1918) who were also botanists. There were several genera named for him, five named Candollea, one in the Dilleniaceae published in 1806 by Jacques Julien Houtou de Labillardiére, one in the Ericaceae published in 1810 by Johann Christian Gottlob Baumgarten, one in the Poaceae published in 1840 by Ernst Gottlieb von Steudel, one in the Polypodiaceae published in 1803 by Charles François Brisseau de Mirbel, and one in the Stylidiaceae also published by Labillardiére in 1805, and Candolleodendron, published in 1966 by Richard Sumner Cowan. His son also had a genus named for him, Candollina. There are several current taxa in the flora of southern Africa, Indigofera candolleana, Prisma-
tocarpus candolleanus, Stylapterus candolleanus, Helichrysum candolleanum, and Euryops candollei, and the likelihood is that they are all named for Augustin de Candolle. (Wikipedia)

Caperonia: for Noël Caperon or Capperon of Orleans, an apothecary who was the first to call Fritillaria by that name. He was a Protestant and was murdered by a Catholic mob in 1572. The genus was published in 1826 by French botanist Auguste François César Prouvençal de Sainte-Hilaire. (David Hollombe, pers. comm.)

capornii: for Andrew St. Clair Caporn (1893-?) who collected the type specimen of Ruschia capornii. (Etymological Dictionary of Succulent Plant Names)

Cardotiella/cardotii: for Jules Cardot (1860-1934), French botanist, bryologist and plant collector in the Cameroon. He was author of Old World Mosses and co-author of The Mosses of Alaska, and was considered one of the world's leading experts on the mosses of Antarctica. The genus was published in 1981 by Australian botanist Dale Hadley Vitt, and there is a moss taxon Dicranella cardotii that was probably also named for him. (Dale Vitt, pers. comm.)

Carlina: supposedly for the emperor Charlemagne (742-814) whose army was devastated by a plague, and when he prayed that it be cured, an angel appeared to him and revealed the carline thistle (probably Carlina acaulis or C. vulgaris) which saved them from the pestilence. The genus was published by Swedish botanist Carl Linnaeus in 1753. (The Names of Plants)

caroli-henrici: for Karl Heinz Rechinger (1906-1998), Austrian botanist, son of botanist Karl Rechinger (1867-
1952), Professor of botany at the University of Vienna, member of the Royal Swedish Academy of Sciences, and author of a number of books mostly focused on the Iraq and Iran areas including Flora Iranica. He is commemorated with Pelargonium caroli-henrici. (Etymological Dictionary of Succulent Plant Names)

carolo-schmidtii: for Karl (Carl M.?) Schmidt (1848-1919), plant collector in Madagascar and tropical Africa, owner of the Haage and Schmidt nursery in Erfurt, Germany. There was a former taxon named Crinum carolo-
schmidtii which is now C. lugardiae, and there is a Stapelia caroli-schmidtii and a Cheiridopsis caroli-
schmidtii. The name 'carolo' or 'caroli' as in caroli-henrici and caroli-linnaei have referred to people named Carl or Karl, but this is one that I'd like to have some confirmation for. (Etymological Dictionary of Succulent Plant Names)

carowii: the taxon in southern Africa that bears this specific epithet is Aloe carowii, published in 1938 by Reynolds, with no information on its derivation.

carpianum/carpii: for Bernard Carp (1901-1966), South African naturalist, nurseryman and plant explorer in South Africa. This Bernard Carp apparently went on collecting expeditions with Mr. Harry Hall, the botanist in charge of succulents at Kirstenbosch Gardens. He initiated and financed many expeditions ini southern Africa. He was also Director of Bols Liquor Co. in Cape Town. Taxa in southern Africa with these specific epithets are Conophytum carpianum and Stoeberia carpii. (Etymological Dictionary of Succulent Plant Names; Memories of a Scientist: the Carp Expedition to the Save River in Zimbabwe by William Büttiker-Otto)

carringtoniana: for João Carrington Simões da Costa (1891-1892), Portuguese geologist, professor at the University of Porto, president of the Geological Society of Portugal, author of secondary school textbooks, commemorated with Vepris carringtoniana. (David Hollombe, pers. comm.)

Casearia: for Johannes Casearius (1642-1678), Dutch clergyman and missionary, minister of the Dutch East India Company, and co-author of the first two volumes of Hendrik A. Van Rheede's Hortus Indicus Mala-
baricus. The genus was published in 1760 by Dutch-born Austrian botanist Nicolaus Joseph von Jacquin. (CRC World Dictionary of Plant Names)

Cassebeera: for Dr. Johann Heinrich Cassebeer (1785-1850), German botanist, bryologist and geologist. a wine expert and a specialist in cryptogams. The fern genus Cassebeera was published in 1824 by German pteridologist Georg Friedrich Kaulfuss, but is apparently no longer considered a valid genus, the species having been moved to Doryopteris.

Cassinia: for Alexandre Henri Gabriel Comte de Cassini (1781-1832), French botanist and naturalist. "He was the youngest of five children of Jacques Dominique, Comte de Cassini, who had succeeded his father as the director of the Paris Observatory, famous for completing the map of France. He was also the great-great-grand-
son of famous Italian-French astronomer, Giovanni Domenico Cassini, discoverer of Jupiter's Great Red Spot and the Cassini division in Saturn's rings. The genus Cassinia was named in his honour by the botanist Robert Brown. He named many flowering plants and new genera in the sunflower family (Asteraceae), many of them from North America. He published 65 papers and 11 reviews in the [Nouveau] Bulletin des Sciences par la Société Philomatique de Paris between 1812 and 1821. In 1825, A. Cassini placed the North American taxa of Prenanthes in the new genus Nabalus, now considered a subgenus of Prenanthes (family Asteraceae, tribe Lactuceae). In 1828 he named Dugaldia hoopesii for the Scottish naturalist Dugald Stewart (1753-1828)." The genus Cassinia was published in 1813 by British botanist Robert Brown. (Wikipedia)

catherinae: for Mrs. Catherine van der Byl (1882- ), who helped Prof. Robert Harold Compton to find wild plants for the first description of this species.

cavanillesiana/cavanillesii: for Antonio José Cavanilles (1745-1804), Spanish taxonomic botanist and clergyman, director of the Royal Botanical Garden and Professor of botany at Madrid who was one of the first Spanish botanists to use the classification system of Linnaeus. He is commemorated with Pelargonium cavanillesii and probably also with the former taxon Hermannia cavanillesiana (now C. lavandulifolia.) (Wikipedia; JSTOR)

cecilae/ceciliae/cecilii: for the Honorable Mrs. Evelyn Cecil (1865-1941) (née Alicia Margaret Amherst, later Lady Rockley), plant collector and botanical illustrator, author of several books on gardens and Wild Flowers of the Great Dominions of the British Empire. Selago cecilae and Schizochilus cecilii were both collected by Mrs. Cecil in Zimbabwe, and there is a record of Tapinanthus ceciliae being collected by a "Cecil," also in Zimbabwe (actually Rhodesia), so they are probably all named for her. There is also an Indigofera cecilii, but I don't know about that one. (Gunn & Codd)

Celmisia: after Celmision (Celmisios), son of the Greek nymph Alciope. The genus was published in 1825 by French botanist and naturalist Alexandre Henri Gabriel de Cassini. (CRC World Dictionary of Plant Names)

chalwinii: for Henry James Chalwin (1849-1910), a horticulturist with the Gold Coast Botanical Station and Superintendent of the Cape Town Botanical Garden. He amassed one of the best collections of orchids in South Africa. The former taxon Haworthia chalwinii published by Marloth and Berger in 1906 has been synonymized to H. coarctata var. coarctata.

chamissonis: for Ludolf Adelbert von Chamisso (1781-1838) (born Louis Charles Adélaïde de Chamissot), a French-born German poet, gifted scientist, botanist, philologist and explorer. He was born French with the name Vicomte de Chamisso and baptized Louis Charles Adélaïde and later in Prussia took the name Adelbert. He spent several years in the Prussian army. In 1818 after returning he was made custodian of the botanical gardens in Berlin, and was elected a member of the Academy of Sciences. He botanized with Johann Friedrich Gustav von Eschscholtz in the San Francisco Bay region in 1816 and accompanied him on a Russian expedition in search of the Northwest Passage. All of the species in southern Africa that used to bear this specific epithet, Aspalathus, Philippia and Juncus, have all disappeared through synonymy. (Gunn & Codd; Wikipedia)

chapelieri: for Louis Armand Chapelier (1779-1806), a plant collector in Madagascar and Mauritius, commemorated with Eragrostis chapelieri. (Etymological Dictionary of Grasses)

chaplinii: there is a JSTOR record of Strumaria chaplinii being collected by a J. Chaplin in South Africa in 1947, with no further information. The taxon was published originally by Winsome Fanny Barker and then more recently in 1994 by South African botanist Dierdré Anne Snijman.

chapmannii/Chapmanolirion: possibly for James Chapman (1831-1872), a South African explorer, hunter, trader and photographer. The genus was published in 1909 by German botanist and explorer Moritz Kurt Dinter. Kew Herbarium has a record of Pancratium chapmannii (which is now P. tenuifolium) being collected with no date in South Africa by a J. Chapmann. This may or may not refer to the same individual.

charlieriana: for Captain H.A. Charlier (?-1887), former Director of the German company handling coloni-
zation and administration for South-West Africa, commemorated with Indigofera charlieriana. (David Hol-
lombe, pers. comm.)

The former taxa in southern Africa that bore this specific epithet were Herschelia char-
pentieriana, published by Friedrich Wilhelm Ludwig Kraenzlin, and Disa charpentieriana, published by Heinrich Gustav Reichenbach, both now synonymized to Disa multifida. He also had the genus Charpentiera named for him.

chaseana: for Norman Centlivres Chase (1888-1970), banker and a leading collector of Zimbabwean plants, commemorated with Christella chaseana and Thelypteris chaseana. (Gunn & Codd)

lepis chevalieri in Mali in 1899, also the former taxon Combretum chevalieri (now C. adenogonium). (Etymo-
logical Dictionary of Grasses)

chiarugii: the Harvard University Herbarium list of botanists does have an Alberto Chiarugi (1901-1960), but I don't know for sure if that is the derivation here. There was a taxon named Vernonia chiarugii, published in 1951 by Italian botanist Rodolfo Emilio Giuseppe Pichi Sermolli, which has now been synonymized to Gymnan-
themum myrianthemum.

chilversii: for a C.W. Chilvers who collected a syntype of Ochna chilversii in South Africa in 1915. (JSTOR)

chippindalliae: for Lucy Katherine Armitage Chippindall (later Mrs. A.O. Crook) (1913-1992), South African agrostologist, Technical Assistant in the Division of Botany, Pretoria, author of Grasses of Southern Africa, commemorated with Pentaschistis chippindalliae. Gunn & Codd give her name as Lucy Kathleen Armitage Chippindall, but the Harvard University Herbarium list of botanists has it as Katherine. (Etymological Diction-Alberto Chiarugi (1901-1960)ary of Grasses; Gunn & Codd)

Chironia: after Chiron, the good Centaur of Greek mythology who studied medicine, astronomy, music, and other arts, and was a skilled herbalist.

He was the parish priest of Undal. Although the CRC World Dictionary of Plant Names describes him as Danish, he was born in Norway. The genus was published in 1768 by Dutch botanist Nicolaas Laurens Burman. (CRC World Dictionary of Plant Names)

clementiana: for Simón de Roxas Clemente y Rubio (1777-1827), renowned Spanish botanist, librarian at the Madrid Botanic Gardens, author of Variedades de la Vid Común que Vegetan en Andalucía (1807) and Historia Natural de Titaguas.

Coddia/coddiana/coddii: for Dr. Leslie Edward Wastell Codd (1908- 1999), South African botanist, director of the Botanical Resarch Institute in Pretoria from 1963-1973, described many new taxa, published Trees and Shrubs of Kruger National Park, edited the journal Bothalia (1958-1974), helped to found and became president of the South African Association of Botanists, amassed a collection of plant specimens that numbered over 11,000, and co-authored with Mary Gunn of the major biographical work Botanical Explorations of Southern Africa (1981). British biologist and taxonomist Bernard Verdcourt published the genus Coddia in 1981, and Dr. Codd was also honored with the name Kniphofia coddiana and taxa in Hibiscus, Brachystelma, Tylophora, Eulophia, Berkheya, Macrotyloma, Agapanthus, Tulbaghia, Becium and others. (JSTOR)

coetzeei: for Dr. Ben Johan Coetzee (1943- ), South African botanist and ecologist at Kruger National Park, participated in a transect across southern Africa, and has published surveys of the Waterberg Mountains, Mlilwane nature reserve in Swaziland, and the Sudano-Zambesian region. He is commemorated with Bulbine coetzeei. (Etymological Dictionary of Succulent Plant Names; JSTOR)

Coldenia: for Cadwallader Colden (1688-1776), Irish-born Scottish scientist and physician. He studied medi-cine in London, was a historian and botanist, emigrated to America and was the father of the American botanist Jane Colden. Swedish botanist Carl Linnaeus published the genus in 1753. (CRC World Dictionary of Plant Names)

colei/coleorum: for Desmond Thorne Cole (1922- ), South African lecturer and then Professor and Head of Department of African Languages at University of the Witwatersrand, researcher on succulent plants who collected Lithops at over 300 localities, and his wife Naureen Adele Lambert Cole (1935- ), co-authors of Flowering Stones, a study of Lithops. The taxon in southern Africa that used to have the specific epithet colei was Hoodia colei, now Hoodia pilifera, and they are also honored with the name Lithops coleorum. (Gunn & Codd)

colensoi: for Rev. John William Colenso (1814-1883), British-born Bishop of Natal, collected plants there and was responsible for a translation of the Scriptures into the Zulu language. He is commemorated with the species Chiodecton colensoi, and also with Crinum colensoi, a garden synonym of C. moorei. Not to be confused with Rev. William Colenso (1811-1899), New Zealand missionary, printer, botanist and explorer. There are other taxa in southern Africa with the specific epithet colensoica, but I don't know whether that relates to this person or not. (Gunn & Codd)

Columellea: for Lucius Junius Moderatus Columella, Roman soldier and farmer of the 1st century AD who wrote extensively on agriculture. The genus was published by Austrian botanist and chemist Nicolaus Joseph von Jacquin in 1798. (CRC World Dictionary of Plant Names)

Commelina/commelinii: for Jan or Johan Commelin (1629-1692), his nephew Caspar Commelin (1667/1668-
(1901-1960)1731), and possibly his son Caspar as well, all Dutch botanists. The flowers of Commelina have two large showy petals and a single small petal, and according to Stearn supposedly the two large petals repre-
sented (at least for Linnaeus who adopted the name given by Plumier) Commelin senior and the nephew, while the small one represented the son who never achieved anything in the field of botany. The genus Commelina was published in 1753 by Swedish botanist Carl Linnaeus, and there used to be a taxon Aloe commelinii, which is now Aloe perfoliata. (CRC World Dictionary of Plant Names)

commersonii: for Philibert Commerçon (sometimes spelled Commerson) (1727-1773), French naturalist and plant collector who was on de Bougainville's circumglobal expedition beginning in 1766, and who botanized in Mauritius and Madagascar. Other taxa that were given this name include Callitris=Widdringtonia in the Cupressaceae. There is a JSTOR record of a plant collector named M. Commerson with no dates but this person apparently only collected in South America, so Philibert would seem more likely. The taxon in southern Africa that bears this specific epithet is Rhodobrym commersonii, and there are others that have been lost to synonymy. (Etymological Dictionary of Grasses)

comptoniana/comptonii: for Professor Robert Harold Compton (1886-1979), the second director of the National Botanical Gardens of South Africa. He started the Journal of South African Botany in 1935. During the 34 years that he was Director of Kirstenbosch, he was also Professor of Botany at Cape Town University. His interests were mainly in taxonomy. After his retirement he settled in Swaziland where he produced An Annota-
ted Checklist of the Flora of Swaziland. His name is on the Herbarium at Kirstenbosch, he was honored with the name Haworthia comptoniana, and between thirty and forty other species in southern Africa currently bear the specific epithet comptonii, most if not all of which are commemorative of him, so he was without question a major figure in South African botany. (Gunn & Codd)

conradii: the taxon in southern Africa that bears this specific epithet is Conophytum conradii, published in 1937 by South African botanist Harriet Margaret Louisa Bolus, "a courtesy taxon, made at the suggestion of Hans Herre to honor his father Conrad." (David Hollombe, pers. comm.)

(Etymological Dictionary of Succulent Plant Names)

croucheri: for Joseph Croucher (1838-1917), for a time first head gardener and Superintendent at Kew Gardens and succulent plant specialist. In 1869 Hooker had described a species in Curtis's Botanical Journal stating, "This, the handsomest Gasteria of the kind that has hitherto flowered at Kew, is named after the intelligent foreman of the propagating department, Mr. Croucher, under whose care the succulent plants of the Royal Garden are placed, and to whose zeal and special love for this class of plant the collection owes much of its value and interest." (PlantzAfrica)

crozalsiana/crozalsii: for André de Crozals (1861-1932), French lichenologist, author of Lichens observés dans l'Hérault (1909) and Excursions lichénologiques dans le massif du Mont-Blanc (1910), commemorated with Riccia crozalsii and Canoparmelia crozalsiana.

There is also a plant name author named James Cullen (1936- ) but this is obviously too recent. A communication from the Botanical Information Service of the National Herbarium of New South Wales states: "The genus Cullen is possibly named after William Cullen (1710-1790), Professor of Botany, Glasgow. This information comes from Legumes Of The World edited by G. Lewis, B. Schrire, B. Mackinder & M. Lock, published by The Royal Botanic Gardens, Kew, 2005." My thanks to Seanna McCune for her reply. The genus Cullen was published in 1787 by German physician and botanist Friedrich Kasimir Medikus.

He worked at Kew as clerk to the curator of the Royal Gardens, William T. Aiton, and it was there that he met Robert Brown and Joseph Banks. He spent two years in Brazil collecting for Kew, and then was sent to Australia. He also spent time in New Zealand, and during a visit to England was elected a Fellow of the Linnean Society. He is commemorated with Casuarina cunninghamiana and other Australian species. (Australian Dictionary of Biography)

Cunonia: for Johann Christian Cuno (1708-1780), German naturalist who published a book of verse about his garden in which many exotic plants were growing. He made a fortune as a merchant in the West Indies and lived for years in Holland. There seems to be some uncertainty about his date of death. In addition to the 1780 date given above, I have seen 1796 and 1783. The genus was published by Swedish botanist Linnaeus in 1759. (CRC World Dictionary of Plant Names)

cupaniana: for Francesco Cupani (1657-1711), Sicilian monk and author of works on Sicilian plants. He was the first Director of the botanic garden at Misilmeri, Sicily, and author of Catalogus plantarum sicularum Noviter adinventarum (1692), Syllabus plantarum Siciliae Nuper detectarum (1694), Hortus Catholicus (1696), and Pamphyton siculum (1713).

Cussonia: for Pierre Cusson (1727-1783), French physician, botanist, mathematician and professor at the University of Montpellier, an authority on the carrot family. He had travelled extensively throughout Majorca, Spain and the Pyrenees, and amassed an excellent collection of specimens, which were regrettably disposed of by an elderly female relative with whom he lived who cleaned his study in his absence. The genus was published by Swedish botanist Carl Peter Thunberg in 1780. (CRC World Dictionary of Plant Names)

Cuviera: for Georges Léopold Chrétien Frédéric Dagobert, Baron Cuvier (1769-1832), French naturalist. He succeeded Lamarck in the Chair of Comparative Anatomy at the Jardin des Plantes. He founded vertebrate paleontology as a scientific discipline. yet he was not a believer in evolution, being of the opinion that all species were created at once. The genus was published in 1802 by German botanist and physician Georg Ludwig Koeler. (CRC World Dictionary of Plant Names)

Cyclopia: presumably after the mythological Cyclops. The genus was published in the year of his death, 1808, by French botanist Étienne Pierre Ventenat. (CRC World Dictionary of Plant Names)

hagen. Before his untimely death in a traffic accident he wrote extensively on plant systematics and cladistics. He is commemorated with Adenandra dahlgrenii and Penaea dahlgrenii, and also possibly with taxa in Am-
phithalea, Lotononis and Coelidium. He collected over 5000 specimens, mainly in the Cape area but also in Natal, the Transvaal and Rhodesia. The genus Dahlgrenodendron was published in 1988 by South African botanists Frederick Ziervogel Van der Merwe and Abraham Erasmus Van Wyk.(Gunn & Codd)

Dahlia: for Andreas (Anders) Dahl (1751-1789), Swedish botanist and physician, and a student of Linnaeus at Uppsala University. "Thanks to recommendations from Linnaeus, Dahl was employeed as a curator at Claes Alströmer's natural cabinett and botanical garden at Kristinedal in Gamlestaden outside Gothenburg. Andreas Dahl followed Claes Alströmer when he in 1785 moved to his estate Gåsevadsholm outside Kungsbacka, after that he had fallen into a bad economical predicament. In 1786 Dahl was conferred an honorary doctor's degree of medicine in Kiel and in 1787 he became associate professor and botanical demonstrator at the university of Turku (Åbo). To Turku he brought his herbarium which later was destroyed in the big fire in Turku in 1827. Parts of Dahl's collections are preserved and kept in Sahlberg's herbarium in the Botanical Museum at the University of Helsinki and in Giseke's herbarium in the Royal Botanical Garden Edinburgh." (website of the Swedish Museum of Natural History) The genus Dahlia in the family Hamamelidaceae named by Swedish botanist Carl Peter Thunberg in 1792 is now considered by Tropicos to be an invalid publication. There is another genus Dahlia in the Asteraceae family which is also named for him, but it is not represented in South Africa. (CRC World Dictionary of Plant Names)

Dalbergia: for Carl Gustav Dahlberg (1721-1781), Swedish planter, mercenary soldier in Suriname and bot-
anical collector for Linnaeus, and his brother Nils Ericsson Dahlberg (1735/1736-1819/1820), botanist and physician, student of Linnaeus in 1755, personal physician of Gustav III from 1768, twice President of the Swedish Academy of Sciences.

His most important work was Historia plantarum generalis (1586-1687), a compilation of botanical knowledge of his time. He also made many translations of important works into French and Latin. His name is given variously as Daléchamps, Dalechamp, Dalechampius, or D'Aléchamps in the manner in which the spelling of names was not as fixed at that time as it is now. The genus was published by Swedish botanist Carl Linnaeus in 1753. (Elsa Pooley; CRC World Dictionary of Plant Names)

dalenii: for Dr. Cornelius Dalen (1766-1852), Dutch botanist and physician, Director of the Rotterdam Botanic Gardens, commemorated with Gladiolus dalenii. This species was introduced to Europe from KwaZulu-Natal in the 1820's. (Elsa Pooley)

daltonii: for (1) Nick D'Alton, commemorated with Lobostemon daltonii which he brought to the attention of the plant name author Matt Buys who named it for him for his "friendly assistance during many visits to his farm." This is kind of a coincidence, because there is a Mick D'Alton, South African conservationist, Vice-Chairman of the Nuwejaars Wetland Special Management Area (SMA), owner of Kosierskraal Game Farm, and Chairman of the Overberg Crane Group, and we thought this might be the honoree, but the original publication says Nick D'Alton. (2) Sir Joseph Dalton Hooker (1817-1911), English botanist and explorer, friend of Charles Darwin, plant collector at the Cape (briefly); magnus opus: his 7-volume Flora of British India. Taxa in southern Africa with this specific epithet that honors Hooker include Macrotyloma daltonii and the former Sarcostemma daltonii (now S. viminale). (David Hollombe, pers. comm.)

dalyae: for Mary Florence Daly (later Mrs. James Read Heny) (1881-1968), South African botanist, assistant in the Albany Museum Herbarium, collected Albuca dalyae. Both Gunn & Codd and the Harvard University Herbarium list of botanists give her year of death as 1960, but I have seen a photograph of her gravestone and she definitely died March 18, 1968.

danielii: for Thomas Franklin Daniel (1954- ), American botanist, member of the American Society of Plant Taxonomists, the California Botanical Society, the Association for Plant Taxonomy and the California Academy of Sciences, Chairman of the Department of Botany at the California Academy of Sciences, and research pro-
fessor at San Francisco State University. He is commemorated with the former taxon Conophytum danielii, now synonymized to C. jarmilae.

dannenbergii: for Ernst Dannenberg (1826-1896), commemorated with Didymosphaeria dannenbergii. (David Hollombe, pers. comm.)

Danthonia: for D. Étienne Danthoine, 18th century French botanist and agrostologist from Marseilles, student of the grasses of Provence. David Hollombe provided the following: "Étienne Danthoine was born in Manosque in 1739 and died in Grasse in 1794. At the time of his death he was the pharmacist in the military hospital in Grasse. He was a member of the Academy of Sciences of Marseilles and had written articles on grasses, bed-
straws and (published posthumously) gall wasps." The genus was published in 1805 by Swiss botanist Augustin Pyramus de Candolle. (David Hollombe, pers. comm.)

Darea: for George Dare (fl. 1680's, 1690's), English apothecary of Middlesex. A will is dated 1711. The fern genus Darea (now Asplenium) was published in 1789 in Genera Plantarum by Antoine Laurent de Jussieu. (CRC World Dictionary of Plant Names)

Darwin stopped in Cape Town during his voyage on the Beagle and Bonatea darwinii (now B. cassidea) was named in his honor. There was even a suggestion that the genus Bonatea should be named Darwiniana, but that didn't happen.

Daubenya: for Charles Giles Bridle Daubeny (1795-1867), English botanist, geologist and physician, professor of chemistry and botany at Oxford, Fellow of the Linnean Society, and plant collector in the U.S., West Indies and Europe, author of On the Action of Light upon Plants, and of Plants upon the Atmosphere (1836), Sketch of the Geology of North America (1839), Lectures on Roman Husbandry (1857); in Climate: an inquiry into the causes of its differences and into its influence on Vegetable Life (1863), and Essay on the Trees and Shrubs of the Ancients, and a Catalogue of the Trees and Shrubs indigenous to Greece and Italy (1865). He conducted plant experiments at the Oxford Botanical Garden and his name is on the herbarium there. The genus was published by British botanist John Lindley in 1835. (CRC World Dictionary of Plant Names)

Davallia/davallianum: for Edmund Davall (1763-1798), English-born botanist who resided in Switzerland most of his life, plant collector and Fellow of the Linnean Society, established a botanical garden at Orbe, Switzerland. The genus was published by British botanist and entomologist Adrian Hardy Haworth in 1819, and he was also commemorated with the moss taxon Microbryum davallianum which he first found in Switzerland. (CRC World Dictionary of Plant Names; The Mosses of Eastern North America)

(2) George Herbert Davies (1859-1916) who collected Streptocarpus daviesii in 1899 in the Qudeni Forest of Zululand. He was forest officer at Qudeni, where the type was collected, and later chief forest officer for Natal. He was the author of the novel Legions of the Dawn. He was born in Wales and died in KwaZulu Natal. (JSTOR; David Hollombe, pers. comm.)

davisii: there is a JSTOR specimen record of Glottiphyllum davisii being collected by a G.A. Davis in the Ceres Karoo region of South Africa in 1932, so I assume this is who it is named for.

davisonii: the taxon in southern Africa that used to bear this specific epithet was Gladiolus davisonii, now synonymized to G. mortonius, with no information as to its derivation.

davyae: for Alice Bolton (Mrs. Joseph Burtt Davy) (1863-1953).

davyana/davyi: for Joseph Burtt Davy (1870-1940), British botanist and agrostologist working in South Africa, Chief of Division of Botany, Department of Agriculture, trained at Kew, worked at UCLA, appointed botanist in the California state agricultural experiment station 1896-1901, then worked in Washington and finally moved to South Africa where he worked as botanist in the Transvaal Department of Agriculture. In the newly formed Union government he helped create the Department of Botany which became the National Botanical Institute. He was interested mainly in plants of economic or commercial importance. After his retirement, he returned to England, worked at Kew again, and produced in 1926 and 1932 Parts 1 and 2 of the major work A Manual of the Flowering Plants and Ferns of the Transvaal. He is commemorated with Oxalis davyana, Acacia davyi, Ficus burt-davyi, Eumorphia davyi, Streptocarpus davyi, Delosperma davyi and others. (Gunn & Codd)

degenii: since the common name for Peltigera degenii is Degen's felt lichen, I assume that the name here honors someone named Degen, and there are two people who are botanists and plant name authors listed at HUH and IPNI named Árpád von Degen (1866-1934), Hungarian botanist and biologist, and Rosa Degen (1962- ) from Paraguay (?), so these are possibilities. David Hollombe found the original publication and the honoree is Árpád von Degen. (David Hollombe, pers. comm.)

orities, contributed articles and photographs to African Wild Life, also collected shells, minerals, rocks and other items of Africana which he donated to the Cape Town Museum. He is remembered with the former taxon Haworthia dekenahii, which is now H. magnifica. (2) Ivor Dekenah (1904- ), South African magistrate and plant enthusiast, sent succulent plants mainly from Fraserberg to Dr. John Muir. He is commemorated with Anti-

He was commemorated with the former taxon Kanahia delilei which is now K. laniflora, and he also was honored by the genera Delilia and Raffenaldia, neither of which appear in southern Africa. He was the brother of the French botanical artist Eulalie Delile (1800-1840). (Gledhill)

delpierrei: for Georges R. Delpierre, professor of biochemistry at Western Cape University with an interest in bulbs. The taxa in southern Africa that have this specific epithet are Gladiolus delpierrei and the former Trito-
nia delpierrei which is now Tritonia marlothii ssp. delpierrei. (David Hollombe, pers. comm.)

Denekia: for a Dr. Carl Henry Deneke (1735-1803), botanist and surgeon in the Straslund area of Germany in the late 18th century and a friend of the genera's namer Swedish naturalist and botanist Carl Peter Thunberg. The genus was published in 1801. (Elsa Pooley)

dennisii: for Charles Dennis O'Donaghue (1865-1945), British teacher and plant collector of Ilford, Essex, who sent a few specimens to the Smithsonian in 1923. In going back over these entries, I can't find the source that I originally used for this, so it must be considered guardedly pending further confirmation. The taxon in southern Africa that has this name is Conophytum dennisii and it was published in 1931 by British botanist Nicholas Edward Brown.

Derenbergia/derenbergiana: for Dr. Julius Derenberg (1873-1928), German physician and succulent plant collector who had a particular interest in the Mesembs, friend of Moritz Kurt Dinter and Martin Heinrich Gustav Schwantes. The genus Derenbergia was published in 1925 by Schwantes, and he was also commemorated with the species Cheiridopsis derenbergiana, Ebracteola derenbergiana and Anisodontea julii. . (Etymolo-
gical Dictionary of Succulent Plant Names)

Deroemera/Deroemeria: there has been a great deal of confusion, not least of which on my part, about these two generic names which are so similarly spelled. I was able to determine fairly quickly that Deroemeria is an orthographic variant of Deroemera, but there have been conflicting attributions for the name. Victor Samuel Summerhayes, who published at least one taxon in the genus, stated in the Bulletin of Miscellaneous Infor-
mation (Royal Gardens, Kew), Vol. 1927, No. 10 (1927), that Heinrich Gustav Reichenbach published the genus Deroemera in 1852 to honor Johann Jacob Roemer (1763-1819), Swiss physician, entomologist and professor of botany at the University of Zurich, and author of Genera Insectorum Linnaei et Fabricii (1789), a beautiful work with illustrations drawn and engraved by the Swiss artist and entomologist Johann Rudolph Schellenberg. He proceeded to explain in the Kew Bulletin, Vol 14, No. 1 (1960), that the genus Deroemera, which was published by Reichenbach in 1852, was later joined by Reichenbach with genus Holothrix on the basis that the two genera were not sufficiently distinct in certain botanical characteristics. Still later he apparently had a further change of heart and along with Alfred Barton Rendle resuscitated his original genus but spelled it incorrectly as Deroemeria, giving rise to much of the confusion that today exists regarding these names. The CRC World Dictionary of Plant Names attributed the generic name, incorrectly I at first thought, to a Mr. de Roemer (fl. 1852). Both the IPNI list of authors and the HUH index of botanists do include an R. de Roemer (fl. 1852), who is mentioned as well in a couple of other sources such as Flora Europea: Plantaginaceae to Compositae (and Rubiaceae) by British botanist Thomas Gaskell Tutin. Finally David Hollombe provided me with a definitive source, Heinrich Gustav Reichenbach's original description of Deroemera in his publication 'De Pollinis Orchidearum' (1852) in which he states "Dicavi nobilissimo Do Roemer, Löthainensi ас Neumarkensi, qui thesaurorum botanicorum usum magna cum humanitate mihi concessit," and which refers to the German botanist Rudolf Benno von Römer (Roemer) of Neumark and Löthain (1803-1870) who maintained an exten-
sive botanical library with valuable prints and was also honored with the genus Loethainia. According to the Plant List website maintained by Kew Gardens, all species of what used to be Deroemera are now synonyms of Holothrix, and the taxon in southern Africa that belonged to the genus Deroemera, D. culveri, is now synony-
mized to Holothrix culveri. The generic names Roemeria and Roemera (both honoring Johann Jacob Roemer) had already been used, so Reichenbach chose Deroemera. ("African Orchids: XXVII" by V.S. Summerhayes, Kew Bulletin, Vol 14, No. 1, 1960; De Pollinis Orchidearum; Wikipedia; CRC World Dictionary of Plant Names)

Deschampsia: for Louis Auguste Deschamps (1765-1842), French botanist, naturalist and surgeon. A website of the National Herbarium of the Netherlands offers this information: "Surgeon-Naturalist of the expedition of the ‘Recherche’ in search of [the explorer Jean-François de Galaup, Comte de la Perouse] 1791-1793. When the expedition stranded in Java he was interned for a short interval, but Governor van Overstraten offered him to stay in Java to make natural history investigations for which he would get facilities to extend his research into the interior of the island. Deschamps accepted, as he says, in the interest of science, and took leave of his travel companions. In the subsequent years this Frenchman made numerous trips, and he certainly has been the first to make botanical collections on several of the mountains and in many remote localities of Java. It is a pity that evidently none of his botanical specimens are preserved, as his diary, drawings and MS. papers are such that we might have expected extremely valuable material. During his travels he was partly accompanied by some young assistants who were to help him with the description and drawing of plants and animals (he collected fishes too!). Afterwards he settled at Batavia as a physician until 1802, in which year he sailed for Mauritius. Later he settled at St. Omer in France." The genus Deschampsia was published in 1812 by French naturalist Ambroise Marie Françoise Joseph Palisot, Baron de Beauvois.

Descurainia: for François Déscourain (1658-1740), French pharmacist and botanist, and friend of Antoine and Bernard de Jussieu. The genus Descurainia was published in 1836 by British botanist Philip Barker Webb and French naturalist Sabin Berthelot. (CRC World Dictionary of Plant Names)

Desmazeria: for Jean Baptiste Henri Joseph Desmazieres (1786-1862), French botanist, horticulturist, mer-
chant and author of Plantes cryptogrames de Nord de la France. He was the editor of the journals Annales des sciences naturelles and the Bulletin de la société des sciences de Lille, and he was a member of the Botanical Society of France, the Imperial Society of Science and the Botanical Society of Brussels. The genus was published in 1822 by Belgian botanist Barthélemy Charles Joseph Dumortier. (CRC World Dictionary of Plant Names)

desmidtii: for R.A.H. Flugge de Smidt (1886-1969), South African plant collector, soldier, engineer, president of the South African Institute for Mining and Metallurgy, author and llustrator of Flowers by the Roadside (1947). He is commemorated with the species Watsonia desmidtii which is now W. wilmaniae.(Gunn & Codd)

despreauxii: for J.M. Despréaux (1794-1843), French botanist specializing in bryophytes and lichens. He is commemorated with Heppia despreauxii.

desvauxii: for Nicaise Auguste Desvaux (1784-1856) (often written as Auguste-Nicaise or Augustin-Nicaise), French botanist, Director of the Angers Botanic Garden, author of Nomologie botanique (1817) and Flore de l'Anjou (1827). He is commemorated with Enneapogon desvauxii, and the genus Desvauxia which does not appear in southern Africa. (CRC World Dictionary of Grasses)

Deverra: after the Roman goddess of brooms (from the Latin deverro, 'to sweep away') who protects women in labor, and patroness of midwives. Supposedly the brooms were used to sweep away the evil spirits from the houses where the babies were born. This genus was published in 1830 by Swiss botanist Augustin Pyramus de Candolle. (CRC World Dictionary of Plant Names)

devenishii: for Nicholaas James Devenish (1934- ), plant collector in South Africa. He collected Asparagus devenishii in 1964 and there is also a taxon Gymnosporia devenishii that probably relates to him.

Devia: for Dr. Miriam Phoebe de Vos (1912-2005), South African botanist and botany professor at Stellen-
bosch University, author of The Genus Romulea in South Africa, interested in cytotaxonomy and embryology especially of Iridaceae. She was particularly fond of Moraeas and Clivias. The genus Devia was published by South African botanists Peter Goldblatt and John Charles Manning in 1990. (Gunn & Codd)

devriesii: for Vincent de Vries (1953- ), a South African-born pharmacist and teacher of Dutch descent who began a succulent plant nursery around 1990 and later incorporated Hoodia cultivation for the pharmaceutical industry, has done extensive field work in South Africa and has been honored by the names of at least two Haworthia species devriesii and vincentii.

dewetii: for J.F. de Wet (fl. 1937), Headmaster of Vryheid Junior School in S.A., commemorated with Aloe dewetii. (Etymological Dictionary of Succulent Plant Names)

dewevrei: for A. Dewevre (fl. 1895) who collected Aristolochia dewevrei in the Congo in 1895. (JSTOR) This possibly refers to Alfred Prosper Dewèvre (1866-1897), Belgian pharmacist and mycologist. At the behest of the Congolese government, he organized the first purely botanical exploration in the Independent Congo State. He was especially interested in commercial plants such as rubber.

Dewinterella/dewinteri/Dewinteria: for Dr. Bernard de Winter (1924- ), South African botanist at the Botan-
ical Research Institute, Pretoria, and author of Sixty-six Transvaal trees. Dewinterella was published in 1994 by German botanists Dietrich Müller-Doblies and Ute Müller-Doblies, and Dewinteria in 2007 by South African botanists Ernst Jacobus van Jaarsveld and Abraham Erasmus van Wyk. Dr. de Winter was also com-
memorated with Kirkia dewinteri, Silene dewinteri, Aloe dewinteri, Aristida dewinteri and Euclea dewin-
teri. (Etymological Dictionary of Succulent Plant Names; Etymological Dictionary of Grasses; Gunn & Codd)

dickiana: for (Viktor?) Dick, manager of Namaqua Diamond Mines, commemorated with Hexacyrtis dickiana (David Hollombe, pers. comm.)

Dicksonia: for James (Jacobus) J. Dickson (1738-1822), British botanist and mycologist, gardener, botanical collector and nurseryman. He came from a family of nurserymen and in 1772 set up a business as a nurseryman and seedsman in Convent Garden; by 1781 he became interested in cryptogams. Between 1785 and 1801 he produced his Fasciculus plantarum cryptogamicarum Britanniae, a four-volume work in which he published over 400 species of algae and fungi occurring in the British Isles. He was also the author of A Collection of Dried Plants (1789-1791) and Hortus siccus britannicus (1793-1802). He was a fellow of the Royal Soc-
iety, a founder member of the Linnaean Society and a founder member of the Royal Horticultural Society. He was friends with Joseph Banks to whom he introduced his brother- in-law the Scottish explorer Mungo Park, and who sponsored Park's expedition to West Africa in 1795 during which he became the first westerner to see the Niger River. He was also acquainted with the horticulturist William Forsyth. The genus Dicksonia was published in 1788 by French botanist Charles Louis L'Héritier de Brutelle. (CRC World Dictionary of Plant Names; Wikipedia)

dielsiana/dielsii: for Friedrich Ludwig Emil Diels (1874-1945), German botanist who travelled widely through South Africa, Java, Australia and New Zealand, later New Guinea and Ecuador, making large collections of plants, and writing an important monograph on the Droseraceae vice-director and then director of the Berlin-
Dahlem Botanical Gardens. His collections were destroyed in an air raid in 1943. He is commemorated with Diascia dielsiana, Spiloxene dielsiana, Drosera dielsiana, Agathosma dielsiana, Cotula dielsii and the former Crassula dielsii, now C. dentata. (Wikipedia; Gunn & Codd)

diemontianum: for Marius Annè Diemont, Jr. (1912-2001), S. A. Supreme Court Justice and a friend of the author who was allowed to use the judge's house at Boboskloof in the Cold Bokkeveld while studying the plants in the area, commemorated with Leucadendron diemontianum, published in 1972 by South African engineer and botanist Ion James Muirhead Williams. (David Hollombe, pers. comm.)

dieterleniae/dieterlenii: for Anna Dieterlen (1858/9-1945), French missionary and amateur botanist who collected in Lesotho. She is commemorated with many taxa including the current Scleria dieterlenii, Cineraria dieterlenii, Relhania dieterlenii, Wahlenbergia dieterlenii and Cymbopogon dieterlenii, and older names that have been synonymized, such as Funaria dieterlenii (now F. spathulata), Euryops dieterleniae (now E. evansii), Lotononis dieterlenii (now L. lotononoides), Tulbaghia dieterlenii (now T. leucantha), Eragrostis dieterlenii (now E. caesia) and Gladiolus dieterlenii (now G. crassifolius). (Elsa Pooley; Etymological Dictionary of Grasses)

Dietrichia: a number of Dietrichs were botanists including (1) Albert Gottfried Dietrich (1795-1856), curator of the Botanical Garden in Berlin, (2) David Nathaniel Friedrich Dietrich (1800-1888), curator of the Jena Univer-
sity Herbarium and author of a number of botanical works, [since the name was published the name in 1812, these two would seem to be too young to be so honored], (3) Adam Dietrich (1711-1782), botanist, D.N. Dietrich's great-great-uncle, and (4) Johann Friedrich Gottlieb Dietrich (1765-1850), D.N. Dietrich's uncle and editor of an encyclopedia of gardening and botany. This was a well-known botanical family and very likely the genus commemorated one or more of them. The most likely candidate here is J.F.G. Dietrich, and in fact a website called Deutsche Biographie created by the Bavarian State Library makes this assertion, and gives the following: "Dietrich machte als Zwanzigjähriger auf einer botanischen Exkursion bei Jena die Bekanntschaft Goethes, der ihn 1785 als Reisebegleiter nach Karlsbad mitnahm und seinen weiteren Lebensweg bestimmte, indem er ihm mit Unterstützung des Herzogs Karl August von Weimar eine wissenschaftliche Ausbildung in Jena und Reisen ins Ausland (Kew und Chelsea) ermöglichte. 1792-1801 war er herzog|licher Gärtner (ab 1794 Hofgärtner) in Weimar. In dieser Zeit kam er häufig in Berührung mit Goethe, den er für seine botanischen Studien mit Pflanzenmaterial belieferte und auch gärtnerisch betreute. 1801-45 war er als Schöpfer und Garteninspektor (Direktor) des herzoglich Botanischen Gartens in Wilhelmsthal bei Eisenach tätig, erhielt den Titel eines Großherzoglichen Rats, wurde Dr. phil. und Professor der Botanik. Ihm zu Ehren wurde die Pflanzengattung Dietrichia benannt (später zur Gattung Rochea gezogen). Er war seit 1795 einer der frucht-
barsten botanischen und hortensischen Schriftsteller seiner Zeit (besonders lexikographische Neigung) und Mitglied vieler wissenschaftlicher Gesellschaften (unter anderem der Botanischen Gesellschaft zu Regensburg, Gesellschaft naturforschender Freunde zu Berlin, Leipziger ökonomischen Societät)." The fractured Google translation of this is as follows: "Dietrich was the age of twenty on a botanical excursion in Jena the acquaintance of Goethe, who took him in 1785 as companion to Carlsbad and certain his future by giving him with the support of Duke Karl August of Weimar, a scientific education in Jena and trips abroad (Kew and Chelsea) enabled. 1792-1801 he was Duke Licher Gartner (gardener from 1794) in Weimar. In that time he often came into contact with Goethe, he wrote for his botanical studies in plant material supplied and supervised gardening. 1801-45, he served as creator and Services Inspector (Director) of the Duke of botanical gardens in Wilhelm-
sthal in Eisenach, was awarded the title of Grand Ducal Council, was Dr. Phil. and professor of botany. In his honor, was named the plant genus Dietrichia (later moved to the genus Rochea). He was one of the most fruitful since 1795 and hears botanical Saxon writers of his time (especially lexicographic inclination) and a member of many scientific societies (to include the Botanical Society of Ratisbon, society naturally inquiring friends Berlin, Leipzig economic Societat)." I couldn't find any non-German sources to try to clear this up, but the basics are that he was assisted in his botanical career by Goethe, he authored books on botany and horti-
culture, he designed and directed botanical gardens, he visited the Kew, Huntington and Chelsea gardens, and he held a chair as professor of botany. The genus was published in 1812 by Austrian botanist Leopold Trat-
tinnick.

dilleniana/dillenii: for Johann Jacob Dillen (Dillenius) (1684-1747), German botanist, physician and plant collector, professor of botany at Oxford and prolific author. Linneaus spent a month with him at Oxford and afterwards dedicated his Critica Botanica to him. His greatest work was the Historia Muscorum published in 1741. He is commemorated with Opuntia dillenii. (Dictionary of National Biography, Vol. 15)

Dintera/Dinteracanthus/Dinteranthus/dinteri/dinteriana: for Moritz Kurt Dinter (1868-1945), German botanist, explorer, and plant collector in SW Africa. Wikipedia says "Dinter covered an estimated 40,000 km on foot, by wagon and motor vehicle during the course of his collecting trips, which spanned 38 years, in South-
West Africa. His collection of pressed specimens numbered in excess of 8400. Large quantities of living plants and seeds, and his wife's collections, were never numbered." He began his botanical and horticultural studies at the Botanic Gardens of Dresden and Strasbourg. Later he was engaged by Sir Thomas Hanbury to take charge of the wonderful collection of plants at the La Mortola garden, spent six months at Kew Gardens, and then left for South-West Africa where he relied on the sale of botanical specimens for his livelihood, and was hired by the German government to be the botanist for the area. In 1913 he accompanied Adolf Engler on a trip through the area, following which he went to Germany and was forced to remain there for the duration of WWI. His periods of time in South-West Africa were 1897-1914, 1922-1925, 1928-1929 and 1933-1935, during which he described over 100 new species. Many other new species were described by other botanists although taxon-
omic changes have caused some of those names to disappear. His wife Helena Jutta Schilde accompanied him on many expeditions and he placed her name on many new species in recognition of her contributions to his work. He is commemorated with the generic names Dintera, published in 1900 by Austrian botanist Otto Stapf, Dinteracanthus, published in 1915 by Swiss botanist and explorer Hans Schinz, and Dinteranthus, published in 1926 by German botanist Martin Heinrich Gustav Schwantes, and many species names. See also dinterae, kurtdinteri, and Juttadinteria/juttae. (Gunn & Codd; Wikipedia)

dinterae: for Mrs. Helena Jutta Dinter (née Schilde), wife of German botanist and explorer Moritz Kurt Dinter. Her name is on the former taxon Mesembryanthemum dinterae, now synonymized to Chasmatophyllum musculinum.

dipageae: for Mrs. Di Page (fl. 1993), South African naturalist and specialist in the Swartkops Valley bushveld vegetation, commemorated with Drosanthemum dipageae. (Etymological Dictionary of Succulent Plant Names)

Disa: possibly for a mythical Queen Disa of Sweden. (CRC World Dictionary of Plant Names)

Dittrichia: for Manfred Dittrich (1934- ), German botanist, specialist in the Asteraceae, and Director of the Herbarium of the Botanic Garden and Botanical Museum Berlin-Dahlem. The genus was published in 1973 by Swiss botanist Werner Rodolfo Greuter. (CRC World Dictionary of Plant Names)

dixonii: probably for Hugh Neville Dixon (1861-1944), prominent British bryologist, author of the Student's Handbook of British Mosses and Studies in the Bryology of New Zealand, founding member of the Moss Exchange Club, first president of the British Bryological Society. He was also Director of the London Mission-
ary Society and Secretary of the Northamptonshire Naturalists Society and Field Club. His name was placed on several moss species such as Bryum dixonii and Nitella dixonii which are not present in southern Africa. The taxon in southern Africa that has this specific epithet is Zygodon dixonii.

Dobrowskya: for Joseph Dobrowsky (1753-1829), Hungarian theologian and philologist, rector in the general seminary at Hradisch. His fame rests mainly on his slavonic studies but his botanical contributions were also noteworthy. He was temporarily confined to a lunatic asylum but recovered. The genus was published in 1836 by Bohemian botanist Carl Borivoj Presl. (CRC World Dictionary of Plant Names)

dodii: for Anthony Hurt Wolley-Dod (1861-1948), British soldier-botanist who collected in South Africa, Gib-
raltar, California and the U.K., author of several books on flora, commemorated with Staavia dodii, Serruria dodii, Crassula dodii, Helictotrichon dodii, Tritoniopsis dodii, Erica dodii, Phylica dodii and the former Ehrharta dodii (now E. rupestris) and Hypodiscus dodii (now Willdenowia humilis). (Etymological Dictionary of Succulent Plant Names).

Dodonaea: for Rembert Dodoens (or Rembertus Dodonaeus) (1517/1518-1585), Flemish physician and herbalist on the faculty of medicine at Leyden University, court physician to the Austrian emperor Rudolph II in Vienna, prolific writer, and one of the foremost botanists of his day. The genus Dodonaea that appears in southern Africa is in the Sapindaceae family and was published in 1754 by Scottish botanist Philip Miller, but there were two other genera at one time named for him, both of them now considered to be invalid publications, in the Rutaceae and the Anacardiaceae. (CRC World Dictionary of Plant Names)

dodsoniana: for Dr. John (Jay) W. Dodson (1901-1999), American succulent enthusiast and founder of the International Succulent Institute, commemorated with Haworthia dodsoniana. (Etymological Dictionary of Succulent Plant Names)

Doellia: possibly for German botanist Johann Christoph Doell or Döll (1808-1885), author of Rheinische Flora (1843). A genus of grasses, Doellochloa, was also named for this same person, and specific names of doellii and doelliana refer to him, so this is the likely derivation. The genus was published in 1843 by German botanist Carl Heinrich 'Bipontinus' Schultz (so named to differentiate him from the other contemporaneous German botanist Carl Heinrich Schultz called Carl Heinrich 'Schultzenstein' Schultz).

doidgeae/doidgeana: for Ethel Mary Doidge (1887-1965), British-born mycologist and plant bacteriologist, assistant to Dr. I.B. Pole Evans in the Transvaal Department of Agriculture, author of the major work The South African Fungi and Lichens, carried out important work in the fields of taxonomic mycology, and bacterial and fungal diseases of crop plants. She is commemorated with Crotalaria doidgeae and Aplanodes doideana. (Gunn & Codd)

doldii: for Anthony (Tony) Patrick Dold (1965- ), botanist at the Schoenland Herbarium, Rhodes University, Grahamstown, RSA, commemorated with the former taxa Orbea doldii, now synonymized to Orbea mac-
loughlinii, and Haworthia cooperi var. doldii, now synonymized to Haworthia cooperi var. cooperi. (Ety-
mological Dictionary of Succulent Plant Names)

Dombeya: for Joseph Dombey (1742-1794), French botanist, physician, naturalist, explorer and traveller in Chile and Peru, author of Flore Péruvienne, L'Herbier de Dombey explique, and Observations de Dombey faites au Chili et au Pérou, all of which were published posthumously. He was at one time in Paris an assistant to botanist Bernard de Jussieu, and in 1777 was appointed royal botanist on an expedition to South America led by Spanish botanists Hipólito Ruiz and José Pavón. He gathered much valuable information relating to the cin-
chona plant, from which quinine was derived. He also put together a large herbarium of Peruvian plants. He had bad luck regarding the things he collected as the British captured the ship carrying his collection home and never returned it, and then the local authorities in Callao, Peru, confiscated over 300 original illustrations of rare plants on the pretext that works of native artists were not allowed to be exported. These illustrations were given to Pavón and Ruiz, who used them in their work Flora Peruviana et Chilensis. He was appointed as physician-
in-chief for the city of Concepcion, Chile, during a cholera outbreak. His bad luck continued when he arrived in Cadiz and more than half of his collection was siezed by Spanish authorities who did not want him to publish before Ruiz and Pavón. He returned to France in 1785 and retired to Lyon, where he became involved in the French Revolution as a surgeon in a military hospital. In 1793 he undertook a mission to the United States to collect botanical specimens and, more importantly, to carry metric measurements to the new American govern-
ment, measurements which if he had been able to deliver them might have made the United States a metric country today, but he had one final series of unlucky episodes, and I quote the following description of these events from the website of PhysicsWorld.com: "Due to a series of misfortunes, Dombey never made it to Ameri-
can shores. In March, as the boat neared Philadelphia, a fierce storm damaged the brig and drove it south to the Antilles, where it had to land at Point-à-Pitre in Guadeloupe. This French colony was as politically divided as France itself. Its governor was royalist, but Point-à-Pitre was full of revolutionary sympathizers. Dombey was helpless to avoid becoming a political pawn. The presence of an emissary of the revered Committee of Public Safety from the home country inflamed the fervour of the locals against the governor, who had Dombey arrested and imprisoned. A mob amassed to demand the release of the man who was an official representative of the French government. Dombey's release incited the mob to take revenge against his captors. Standing on the bank of a channel, Dombey tried to stop the violence, but was pushed off the bank into the water. He was uncon-
scious when fished out, and caught a raging fever. The governor took Dombey into custody, interrogated him and put him back aboard the Soon. Right after it left the harbour, the ship was attacked by British privateers who seized its cargo and took the crew hostage. Despite disguising himself as a Spanish sailor, Dombey was recognized and imprisoned for ransom at the British colony of Montserrat, where in April – still ailing – he died and was buried." Other indications of his bad luck were that he was orphaned at the age of 14 and contracted dysentery while in South America. The genus was published in 1786 by French naturalist Jean Baptiste Antoine Pierre de Monet de Lamarck. (CRC World Dictionary of Plant Names; PhysicsWorld.com)

domokosii: for Janos Domokos (1904-1978), Hungarian botanist specializing in horticulture, travelled with the author iin Transylvania, commemorated with Xanthoparmelia domokosii. (David Hollombe, pers. comm.)

donianum: for David Don (1799-1841), worked at the Chelsea Physic Garden in London, was keeper of Aylmer Bourke Lambert’s library and herbarium, met Cuvier and Humboldt in Paris, appointed librarian to the
Linnean Society, and was professor of botany at King’s College, London. He wrote Volumes 5-7 of Robert Sweet's British Flower Garden, and was the brother of Scottish botanist and plant collector George Don (1798-1856) who collected in Africa and elsewhere. He is commemorated with Bryum donianum. (David Hollombe, pers. comm.)

Doodia: for Samuel Doody (1656-1706), British botanist, pharmacist, Curator of the Chelsea Physic Garden, student of cryptogams, Fellow of the Royal Society, and plant collector for the Rev. Adam Buddle. The genus was published in 1810 by Scottish botanist Robert Brown. (CRC World Dictionary of Plant Names)

doreeniae: for Grace Doreen Court (1928- ), author of Succulent Flora of South Africa, which is regrettably out of print. She is commemorated with Gasteria doreeniae.

Doria: possibly for Captaine Andreas Dorias (Andrea Dorea) (1468-1560), an Italian nautical pioneer, admiral, statesman and contemporary of Christopher Columbus. There are two listings for the publication of the genus Doria in the Asteraceae both in IPNI and Tropicos, the first by German botanist Philipp Conrad Fabricius in 1759 and second by Swedish botanist Carl Peter Thunberg in 1800.

dorotheae: for Dr. Dorothea Christina van Huyssteen, the daughter of Aletta Helena Eksteen and Dr. D.P. van Huyssteen who cultivated the type specimen of Lithops eksteeniae (=L. dorotheae). (Etymological Diction-
ary of Succulent Plant Names)

Dorotheanthus: for Dorothea Schwantes (1849-?) (née Meyer), wife of farmer Jurgen Meyer and mother of German botanist Gustav Martin Heinrich Gustav Schwantes who published it in her honor in 1927. (Plantz-
Africa)

Dortmannia: for a certain Herr Dortmann, Dutch apothecary. The genus was published in 1891 by German botanist Carl Ernst Otto Kuntze.

Dovea: for Heinrich Wilhelm Dove (1803-1879), Prussian meteorologist and physicist, a professor at the Uni-
versity of Königsberg, Director of the Prussian Meteorological Institute. He was an associate professor at the University of Königsberg, an associate professorship at the University of Berlin, and then a full professor at the Friedrich-Wilhelms-Universität. He was also the Director of the Prussian Meteorological Institute and studied the effect of climate on the growth of plants. He was a Fellow of the Royal Society and a member of the Prus-
sian Academy of Sciences, and has a crater on the moon named after him. The genus was published in 1841 by German botanist Karl Sigismund Kunth. (Wikipedia)

Dregea/dregeana/dregeanum/dregeanus/dregei/Dregeochloa: for Johann Franz (Jean Francois) Drège (1794-1881), German plant collector and a botanical explorer and traveller who arrived in the Cape in 1826 with his brother Wilhelm Eduard to join his other brother Carl Friedrich who had come in 1821 (CRC World Dictionary of Plant Names). He was employed at various major botanic gardens at Riga, Munich, Berlin and St. Petersburg. After joining his brother Carl in South Africa, they established a collecting enterprise with himself collecting botanical specimens and Carl collecting zoological and ethnological specimens. They made several expeditions with Danish botanist Christian Friedrich Ecklon. His herbarium which was transferred to Berlin in 1915 was largely destroyed during WWII. Judging by the number of species on which his name appears and by the copious records he kept of collections and geographic localities, he is clearly one of the most significant plant collectors ever to have worked in South Africa. The genus Dregea in the Apocynaceae was published by Ger-
man botanist Ernst Heinrich Friedrich Meyer. There was at one time a genus Dregea in the Apiaceae which was published by Ecklon and Zeyher in 1837, but is no longer considered valid.

droogmansianum: the only reference I could come up with that might explain this name is to Frans Andre Hu-
bert Droogmans (1858-1938), Belgian politician and Secretary-General of the Department of Finance of the Congo Free State, chairman of the Comité Spécial du Katanga (1900-1929) and author of Notices sur le Bas-
Congo and Carte du Bas Congo. The taxa in southern Africa that carried this specific epithet was Trichodes-
ma droogmansianum, which was collected in the Congo and published by Belgian botanists Émile Auguste Joseph de Wildeman and Théophile Alexis Durand, and is now T. physaloides.

drudeana: for Carl Georg Oscar Drude (1852-1933), German botanist and university professor. He was the Director of the Botanical Garden of Dresden, and author of Atlas der Pflanzenverbreitung (1887) and Die Ökologie der Pflanzen (1913), and co-editor with Adolf Engler of Die Vegetation der Erde. I can't confirm this for sure as yet, but he may have been commemorated with the taxon Monsonia drudeana.

drummondii: for (1) Thomas Drummond (1780-1835), Scottish botanist, curator of the Belfast Botanical Gar-
den, an authority on Scottish mosses, and traveller and plant collector in the U.S. He was one of the earliest plant collectors in Texas, which he reached in 1833. He was the brother of the well-known plant collector in Australia James Drummond. I quote the following from the website PlantAnswers.com: "The conditions Drum-
mond endured on his collecting trips through Texas seem incredible by modern standards. Having made arrange-
ments to go to Galveston, Texas by sea, he was struck down by cholera while staying in a small town consisting of only four houses - his captain and eight others died, and the survivors were so weak that Drummond almost starved to death before he recovered. He packed up and sent off about a hundred species each of plants and birds, and snakes, land-shells and seeds, and then returned by boat to Brazoria, Texas across flooded coastal prairie areas from 9 to 15 feet under water. In the autumn he returned to the Texas coast to winter on Galveston Bay, where he again almost starved while waiting for migrating birds to pass through. His health failed and he endured 'bilious fevers', boils, hand infections and ulcers on his legs, but was determined to sail to Cuba to col-
lect and then travel to Key West and through the rest of Florida. What happened then still remains a mystery. Sir Joseph Hooker, who had been receiving many of Drummond's specimens, was sent three boxes containing Drummond's scanty personal possessions, followed by a letter from the American counsel in Havana, Cuba enclosing his death certificate. The letter referred to particulars given in an earlier letter, which was never re-
ceived, so the exact fate of Thomas Drummond has never been known." He is commemorated by the taxon Oenothera drummondii. (2) Robert Baily 'Bob' Drummond (1924-2008), British botanist who worked at Kew on the Flora of Tropical East Africa, former Keeper of the National Herbarium in Harare, Zimbabwe, commem-
orated with Nesaea drummondii and many other taxa which do not appear in southern Africa. One plant he discovered, Triceratella drummondii, while sitting down in the bush having lunch, then he was the next person to find it again, in the same place ten years later. Eventually it turned up on Mozambiquan sand dunes thirty years later and 1000 km away. He was the author of Weeds of Zimbabwe, co-author with Darrel Plowes of Wild Flowers of Zimbabwe, did several treatments for Flora Zambesiaca, and much work on Coates Palgrave's Trees of Southern Africa. (Gunn & Codd; Kew Bulletin Vol. 63)

Duchesnea: for Antoine Nicholas Duchesne (1747-1827), French horticulturist, agronomist and botanist, a pioneer in hybridization at the Royal Gardens at Versailles, author of L'Histoire des Frasiers, first to conduct an in-depth taxonomic study of the genus Cucurbita and produced 258 paintings of gourds of that genus. The genus was published in 1811 by British botanist James Edward Smith. (CRC World Dictionary of Plant Names)

duckittiae/duckittii: for some member of the Duckitt family of the Western Cape. There was a Miss Hilda-
gonda Johanna Duckitt (1840-1905), who was the sixth child of Frederick Duckitt and his wife Hildagonda Johanna Versfeld, who was in turn the great-grandniece of Christiaan Hendrik Persoon.. Assigning particular taxa to her is somewhat problematic because there were many Duckitts, and Cotula duckittiae at least was collected by a Wm. or W.M. Duckitt (fl. 1931). The Duckitt family became one of the oldest English families in South Africa. William Duckitt Sr. was a prominent inventor of agricultural implements and his son William was sent to South Africa by the British Secretary of State for War and the Colonies to introduce agricultural implements to improve farming efficiency. He settled there and among his sons was another William. Another plant collector with the same name is Frederick W. Duckitt (fl. 1997-1998?). The '-ae' name ending usually indicates that it commemorates a woman unless the original names ends in an 'a'. A website I found called the Duket Website (about the Ducket/Duckett/Duckitt family) says "Many of the Duckitt descendants became farmers in the Darling district, and the name became well known throughout South Africa because of the family's association with wild flowers and conservation." There is also mention of a Duckitt Nurseries where a new species of Cymbidium was grown, so this is clearly the right family, but more than one Duckitt probably col-
lected and more than one Duckitt may have been honored buy the assignment of their name to a taxon. There is also a Duckitt (fl. 2008) on the IPNI list of plant name authors.

Dufourea/dufourii: for Léon Jean Marie (or Jean-Marie Léon) Dufour (1780-1865), French physician, botanist, mycologist and naturalist. He was an army doctor during the Peninsular War between France and the allied powers of Spain, Portugal and the United Kingdom that lasted from 1807 to 1814. He was a foreign member of the Royal Swedish Academy of Sciences and the author of Recherches anatomiques sur les Carabiques et sur plusieurs autres Coléoptères and 232 articles on arthropods. The genus was published in 1837 by French botanist Jean Charles Marie Grenier, and he was also commemorated with Sticta dufourii. (CRC World Dictionary of Plant Names; Wikipedia)

duftii: possibly for Gustav Duft (1859-1924?), German mining official in Namibia. Antholyza duftii was collected by a Mr. Duft at Rietfontein, Namibia, in 1899. This appears to be the same Gustav Duft who was involved in the German-Ovaherero War 1904-1908. (David Hollombe, pers. comm.)

Dumasia: for Jean-Baptiste-André Dumas (1800-1884), brilliant French chemist, co-founder of Annales des Sciences Naturelles, a member of the legislative assembly, Minister of Agriculture, a Senator, and President of the Paris Municipal Council, husband of Hermine Brongniart and son-in-law of French chemist, minerologist and zoologist Alexandre Brongniart (1770-1847) who was Director of the Royal Porcelain works at Sévres. Dumas was the brother-in-law of botanist Adolphe Théodore Brongniart, son of Alexandre Brongniart and sister of Hermine Brongniart. The genus Dumasia was published in 1825 by Swiss botanist Augustin Pyramus de Candolle. (CRC World Dictionary of Plant Names)

dummeri: for Richard Arnold Dummer (formerly Dümmer or Duemmer) (1887-1922), South African plant collector who worked in South Africa, Kenya and Uganda, commemorated with the former taxa Andropogon dummeri (now A. schirensis) and Nanobryum dummeri (now Fissidens gladiolus). There is also a current taxon in the Asteraceae, Marasmodes dummeri, which is probably also commemorative of him, although I can't be certain because JSTOR records show an F. Dümmer who collected in South Africa around 1911. However R. Dummer could easily have been mistaken for F. Dummer in the written records, and certainly 1911 is within the period of time that R. Dummer was working, so this could refer to Richard Arnold Dummer as well. (Etymological Dictionary of Grasses; CRC World Dictionary of Grasses)

Dumortiera: for Barthélemy Charles Joseph, Baron Dumortier (Barthélemy Charles Joseph Dumortier) (1797-
1878), a Belgian politician and botanist, member of the Académie de Bruxelles and chairman of the Société Royale de Botanique de Belgique, author of Observations sur les graminées de la flore de Belgique (1823), Flora Belgica (1827) and Analyse des familles des plantes, avec l'indication des principaux genres qui s'y rattachent (1829). He also had a great deal to do with the creation of the state botanic garden. The genus was published in 1824 by German botanist Christian Gottfried Daniel Nees von Esenbeck. (National Botanic Garden of Belgium History)

dunantii: for Philippe Dunant de Salatin (1797-1866), Swiss botanist, associate of Jean Louis Berlandier, commemorated with Roella dunantii and Wahlenbergii dunantii. (Histoire de la Botanique Genevoise by Augustin Pyramus de Candolle)

duncaniae: the taxon in southern Africa that bears this specific epithet is Lejeunea duncaniae, published in 1961 by Swedish botanist Sigfrid Wilhelm Arnell. Originally described by Thomas Robertson Sim in 1926 as Stylolejeunea duncaniae, the type was collected by a Mrs. Duncan at Hells Gate, Uitenhage.  Mrs. Duncan also collected a number of other bryophyte specimens, including other Sim types. (David Hollombe, pers. comm.)

duncanii: for (1) Graham Dugald Duncan (1959- ), South African horticulturist and plant collector who worked at Kirstenbosch, winner in 2001 of the Herbert Medal, the highest award the International Bulb Society bestows (Lachenalia). (2) W. Duncan who collected Faucaria duncanii in South Africa.

dunnii: for Edward John Dunn (1844-1937), British-born Australian geologist, author of Geology of Gold and The Bushman, based on his own experiences in South Africa. He prepared the first geological map of South Africa, and is listed in JSTOR records as a plant collector. He is also on the list of South African plant botanical authors although I don't know what plants he is supposed to have named. (Elsa Pooley)

dunsdoniana: may have the same derivation as the following entry. The taxon in southern Africa that has this specific epithet is Aspalathus dunsdoniana, published in 1960 by Swedish-Danish botanist Rolf Martin Theodor Dahlgren. The description of this taxon was based on a specimen that had been displayed at the British Empire Exhibition in 1925, the displays of flowers for which had been arranged by a Mr. Dunsdon of Caledon.

dunsdonii: for Mr. L. Dunsdon (fl. 1934) according to Etymological Dictionary of Succulent Plant Names. JSTOR records show the taxon Disphyma dunsdonii having been collected by a J. Dunsdon in 1930, but this could easily be an example of a misprint in the records.

duparquetiana: for Rev. Père Charles Victor Aubert Duparquet (1830-1888), French Catholic missionary, naturalist, traveller and collector in Nambia, Angola, Gabon and Nigeria. He was commemorated with the former taxon Nerine duparquetiana, now N. laticoma. (Gunn & Codd)

duplessiae/duplessii: for Miss Rosalie Du Plessis (later Mrs. C. Gill) (fl. 1932-1955), staff member of the Bolus Herbarium who collected Acrodon duplessiae and Drosanthemum duplessiae in South Africa in 1932, according to Etymological Dictionary of Succulent Plant Names and JSTOR collection records. The Women and Cacti website however says that these two taxa are named for an Enid du Plessis (1881- ) who may or may not be the same individual. The JSTOR plant collectors list does have an Enid Phoebe du Plessis but gives her birth year as 1929. Gunn & Codd have an entry for South African botanist Enid Phoebe du Plessis (née Immelman) (1929-?), lecturer at Cape Town University and Rhodes University, on the staff of Kirsten-
bosch Botanical Gardens, and co-author with Hilda Mason of Western Cape Sandveld Flowers. According to this entry Enid Phoebe du Plessis is commemorated with Oxalis dines. I think the bottom line is that the Women and Cacti site is wrong. There is also an entry in Gunn & Codd for a Stefanus Johannes du Plessis (1908-?), South African plant pathologist, but how he relates to the others with the same last name I have no idea. A former taxon in southern Africa is Cheiridopsis duplessii, now synonymized to C. namaquensis, but I don't know who this is named for. There are also other collectors in Africa with the name du Plessis.

durandii: for Théophile Alexis Durand (1855-1912), Belgian botanist, author of Sylloge Florae Congolanae written in collaboration with his daughter Hélène, a famous plant illustrator. He began his career by collecting plants as a youth and then after moving to Switzerland for health reasons began working with botanist Henri Francois Pittier on Swiss flora. In 1879 he became a volunteer at the state botanic garden in Brussels and soon was offered a job there. His writing on various botanical subjects led to the publication of Index Generum Phanerogamarum in 1888 and eventually, after becoming an authority on Congolese plants, to the Sylloge Florae Congolanae (1909) written in collaboration with his daughter Hélène, a famous plant illustrator. He was the director of the National Botanical Garden after the retirement of François Crépin. He is commemorated in the old taxon Celtis durandii which has now been synonymized to C. gomphophylla. (National Botanic Garden of Belgium History)

Duranta: for Castore Durante (1529-1590), Italian botanist-herbalist and poet, physician to Pope Sixtus V, author of De bonitate et vitio alimentorum centuria (The Treasure of Health) (1565) and Herbario Nuovo (1585). The genus was published by Swedish botanist Carl Linnaeus in 1754. (CRC World Dictionary of Plant Names)

dusenii: for Per Karl Hjalmar Dusén (1855-1926), Swedish botanist who collected plants in Cameroon and Liberia, explorer and botanical collector, civil engineer, bryologist and author of New and Some Little Known Mosses from the West Coast of Africa, commemorated with Trachyphyllum dusenii and the outdated taxon Lophocolea dusenii, now synonymized to L. lucida. (CRC World Dictionary of Grasses)

Duthiastrum/duthiae/duthieae: for Dr. Augusta Vera Duthie (1881-1963), South African plant collector, born in Knysna, lecturer in botany at Victoria College which later became Stellenbosch University, established the Stellenbosch herbarium, spent a year at Cambridge (1912) and a year in Australia (1920). She was commemor-
ated with the taxa Psilocaulon duthiae, Ruschia duthiae, Stomatium duthiae, Ischyrolepis duthieae, Erica duthieae, Eriospermum duthieae and Impatiens duthieae. The genus Duthiastrum was published in her honor in 1975 by South African botanist Miriam Phoebe de Vos. Her name is also on the Duthie's golden mole, Chlorotalpa duthieae. (CRC World Dictionary of Plant Names; The Eponym Dictionary of Mammals; Gunn & Codd)

Duvalia: for Henri Auguste Duval (1777-1814), French physician and botanist, famous for his catalogue Plantae succulenta in horto Alenconio (1809), and author of Enumeratio plantarum succulentum in horto Alenconio, first person to describe the plant genera Gasteria, Haworthia and Ligularia, and author of a book on all the species found naturally in the environs of Paris. Both the genus Duvalia in the Fabaceae, published by Aimé Jacques Alexandre Bonpland in 1816, and the genus Duvalia in the Apocynaceae, published by Adrian Hardy Haworth, are named for this individual. Duval named the genus Haworthia in 1809 for Haworth and Haworth returned the favor in 1812. (CRC World Dictionary of Plant Names; Wikipedia; Gledhill)

Duvernoia/duvernoia: for Johann Georg Duvernoy (1692-1759), German botanist and professor of anatomy and surgery who studied under Joseph Pitton de Tournefort. One of his students was the botanist Johann Georg Gmelin and another was Victor Albrecht von Haller. He established that certain large bones found in Siberia belonged to mammoths and not elephants, and was the author of Designatio Plantarum Circa Tubingensem Arcem Florentium (1722) about the native flora of the Tubingen area. He was honored with the name Adhat-
oda duvernoia, which has interestingly been synonymized to Duvernoia adhatodoides. The genus Duvernoia was published in 1847 by German botanist Christian Gottfried Daniel Nees von Esenbeck. (CRC World Dictionary of Plant Names)

dyckii: for Fürst Joseph Salm-Reifferscheid-Dyck (1773-1861), recorded in the HUH list of botanists as Jos-
eph Franz Maria Anton Hubert Ignatz Fürst zu Salm-Reifferscheid Dyck or Joseph Salm-Reifferscheid Dyck, German botanist, botanical artist, horticulturist and succulent plant collector, owner of the Castle Dyck, com-
memorated with Lampranthus dyckii. He also has two genera named for him, Dyckia and Salmea, neither of which appear in southern Africa. (Etymological Dictionary of Succulent Plant Names)

dyeri/dyerianus: for (1) Sir William Turner Thiselton-Dyer (1843-1928), British botanist, commemorated with Aloe dyeri. (2) Dr. Robert Allen Dyer (1900-1987), Director of the Botanical Research Institute in Praetoria, South Africa. He is commemorated with Encephalartos dyerianus, and taxa with the specific name dyeri in Brachystelma, Eriospermum, Acacia, Agapanthus, Cylindrophyllum, Hereroa, Euryops, Limonium, Delosperma, Rhombophyllum and Raphionacme. (PlantzAfrica, Etymological Dictionary of Succulent Plant Names)

Dyerophytum: for Sir William Turner Thiselton-Dyer (1843-1928), British botanist. The genus was published in 1891 by German botanist Carl Ernst Otto Kuntze. (CRC World Dictionary of Plant Names)

dykei: for Edward Stuart Cardinal Dyke (c. 1873-1915), "South African railway worker, mountaineer, plant collector, and photographer. Marloth considered Dyke’s landscape and botanical photography among the best achieved, and published a considerable number of his photographs in his Flora of South Africa (1913-1915)." He died of wounds suffered in South-west Africa during World War I. He is commemorated with the taxa Lessertia dykei, Syncarpha dykei and the outdated taxa Protea dykei (now P. rupicola) and Erica dykei (now E. thodei). (JSTOR)

Dymondia: for Margaret Elizabeth Dryden-Dymond (1909-1952), noted South African horticulturalist, who first collected Dymondia margaretae in 1933. She was on the horticultural staff at Kirstenbosch National Botanical Garden and was honored with both the specific and generic epithet for this taxon. The genus was published in 1953 by South African botanist Robert Harold Compton. (PlantzAfrica)

eardleyae: for Constance Margaret Eardley (1910-1978), systematic botanist, lecturer in botany, University of Adelaide (1933-71) and Curator of the two university herbaria, commemorated with Atriplex eardleyae. (Aus-
tralian Plant Collectors and Illustrators)

Eberlanzia/eberlanzii: for Friedrich Gustav Eberlanz (1879-1966), German decorator, botanist and amateur naturalist, roamed the Namib desert for fifty years collecting plants, animals, minerals and Stone Age tools which he donated to the Lüderitz Museum. The genus Eberlanzia was published in 1926 by German botanist Martin Heinrich Gustav Schwantes, and he is also commemorated with Lithops karasmontana ssp. eberlanzii. (Ety-
mological Dictionary of Succulent Plant Names, CRC World Dictionary of Plant Names)

Ecklonea/ecklonea/eckloneus/eckloniana/ecklonianum/ecklonianus/ecklonii/ecklonis: for Christian Friedrich Ecklon (1795-1868), a Danish pharmacist, botanist and plant collector, and one of the early botanical explorers of the Cape. He moved to South Africa in 1823 as first an apothecary's apprentice and then pharma-
cist and collected plants from 1823 to 1833, returning to Europe in 1828 with vast amounts of collected material which were distributed to German and Danish botanists. During part of this time he worked with Karl Ludwig Philipp Zeyher with whom he published a catalogue of South African plants (1835-7). From 1833 to 1838 he was in Hamburg working on revising his collection, later returning to South Africa where he eventually died. The genus Ecklonea in the Cyperaceae was published in 1829 by German botanist Ernst Gottlieb von Steudel, but it has since become Trinoptiles. Ecklon was one of the most productive plant collectors in South Africa. The specific epithets that are named for him are too numerous to list, with ecklonii being memorialized on at least 23 taxa, eckloniana on at least 18, ecklonis on 8 more, and this doesn't exhaust the full list, not to mention all the taxa that have been synonymized out of existence, and the algae genera Eckloniopsis that does not appear in southern Africa. (CRC World Dictionary of Plant Names)

eckmanii (sometimes listed as ekmanii): for Erik Leonard Ekman (1883-1931), Swedish botanist and explor-
er, worked at the Natural History Museum in Stockholm. "Ekman contributed to the knowledge of the Carib-
bean flora more than any other previous scientist. He described more than 2,000 species new to science (a great many of which are named after him), remarkably so, since by then the flora of the Caribbean was considered to be pretty well documented. His collections are still very actively used in the research on the West-Indian flora. He collected around 36,000 numbers, amounting with duplicates to more than 150,000 specimens. Ekman also made some geographical discoveries, he mapped several mountains of Haiti and was among the first to measure accurately the highest Caribbean mountain, Pico Duarte. Ekman also collected birds, mammals and reptiles, of which several species bear his name, e.g. the Hispaniolan nightjar [Caprimulgus ekmanii]." He is commemor-
ated with the southern African taxon Taraxacum ekmanii. (David Hollombe, pers. comm.; Wikipedia)

edithiae: for Miss Edith Elizabeth Brown (1876-?), daughter of Nicholas Edward Brown, commemorated with Lithops edithiae and Conophytum edithiae. (Women and Cacti)

Edmondia: this genus was published in 1818 by French botanist and naturalist Alexandre Henri Gabriel de Cassini, and many of Cassini's names were not explained, so at the moment the derivation of this one is unknown.

eduardoi: for Dr. Eduardo José Santos Moreira Mendes (1924- ), Portuguese botanist and Director of the Lisbon herbarium, collected in Angola, commemorated with Euphorbia eduardoi. (Etymological Dictionary of Succulent Plant Names)

edwardii: for Edward Taylor (1848-1928), British grower of succulent plants, commemorated with Conophy-
tum edwardii. (Etymological Dictionary of Succulent Plant Names)

edwardsiae: for Gwendoline Edwards (1888-1960), South African teacher and plant collector, founding member of the Arboricultural Society of South Africa, commemorated with Conophytum edwardsiae, Delosperma edwardsiae, Drosanthemum edwardsiae and Lampranthus edwardsiae. (Etymological Dictionary of Succulent Plant Names; Gunn & Codd)

edwardsii: for (1) Denzil Edwards (1929- ), ecologist and plant collector, appointed to Botanical Survey Sec-
tion of the Botanical Research Institute in 1960, later Officer in Charge and then Assistant Director in 1973, President of the Grasslands Society of South Africa. He is commemorated with Combretum edwardsii and possibly Helichrysum edwardsii (Gunn & Codd). (2) Miss G. Edwards in 1917 who collected Campy-
lopus edwardsii in South Africa in 1917. (JSTOR)

Eenia/eenii: for Ture (Thure) Johan Gustaf Een (1837-1883), Swedish mariner and trader, who explored Namibia, went to Tristan da Cunha as Captain of the Telegraph, and served under H.M. Stanley in the founding of the Congo Free State. He died while on board the S.S. Biafra at the Congo River mouth. The genus Eenia was published in 1899 by British botanists William Philip Hiern and Spencer Le Marchant Moore. He was also commemorated with Aspilia eenii, Dicliptera eenii, Hermannia eenii, Lycium eenii, Senecio eenii, Pteronia eenii, Rennera eenii and several others that have been synonymized. (Biographies of Namibian Personalities)

eggelingii: for William Julius ('Joe') Eggeling (1909-1994), Scots-born Assistant Conservator with the Uganda Forest Department, eventually Head of the Forest Department in Uganda, collected thousands of specimens for Kew and the British Museum of Natural History, Director of the Scottish Nature Conservancy, Vice-President of the Scottish Wildlife Trust, Vice-Chairman of the Nature Reserves Committee of Northern Ireland, President of the Scottish Ornithologist Club, and author of The Isle of May: A Scottish Nature Reserve, The Indigenous Trees of the Uganda Protectorate, An Annoted List of the Grasses of the Uganda Protectorate and Elementary Forestry. He was commemorated with the former taxon Erythrina eggelingii, which has been synonymized to E. abyssinica.

ehrenbergiana: for Christian Gottfried Ehrenberg, see next entry. The taxon in southern Africa that has this specific epithet is the former Tephrosia ehrenbergiana, now synonymized to T. villosa. (David Holloombe, pers. comm.)

ehrenbergii: for (1) Christian Gottfried Ehrenberg (1795-1876), German naturalist, zoologist, comparative anatomist, geologist and microscopist, and one of the most famous and productive scientists of his time, studied theology, medicine and natural science, author of the two-volume Symbolae physicae (1828–1834), professor of medicine at Berlin University, member of the Royal Swedish Academy of Sciences and a foreign member of the Royal Society of London. The "Ehrenberg Collection" at the Museum für Naturkunde at the University of Berlin includes 40,000 microscope preparations, 5,000 raw samples, 3,000 pencil and ink drawings, and nearly 1,000 letters of correspondence. He was a member of the Royal Swedish Academy of Sciences and a foreign member of the Royal Society of London. He was the author of Die Infusionsthierchen als vollkommene Organismen (1838 in 2 vols.) and Mikrogeologie (1854 in 2 vols.). The taxon Trichostomum ehrenbergii, which was moved into Barbula by M. Fleisch in 1901, was collected by and named for Christian Gottfried Ehrenberg (David Hollombe, pers. comm.). or (2) Carl August Ehrenberg (1801-1849), brother of Christian Gottfried, a botanist and plant collector who worked for a mining company in Central America and Mexico. He collected plants, animals and minerals for sale in Europe, and was in close correspondence with Diederich Franz Leonhard von Schlectendal, the Director ofthe Royal Herbarium of Berlin. He collected the former Barbula ehrenbergii which is now Barbula bolleana, and thus is presumed to be who this taxon is named for. (Wiki-
pedia)

Ehretia: for George Dionysius Ehret (1708-1770), 18th century German botanical artist, gardener briefly at the Jardin des Plantes in Paris before moving to England, and colleague and correspondent of Linnaeus in Holland, where he was co-author with Linnaeus of the Hortus cliffortianus in 1738, a critical and influential example of early botanical literature. His illustrations were in great demand by people such as Sir Joseph Banks, and more than 3000 of them remain in various collections. The genus Ehretia was published in 1856 by Irish physician and botanist Patrick Browne. (CRC World Dictionary of Plant Names)

Ehrharta: for Jakob Friedrich Ehrhart (1742-1795), Swiss-born German botanist, naturalist and pupil of Linnaeus at Uppsala University and friend of his son, also Director of the Botanical Garden of Hannover. Im-
portant collections of this outstanding German botanist are kept at the Herbarium of Moscow University. He was supposedly the first person to use the rank of subspecies in botanical nomenclature. The genus was pub-
lished in 1841 by German botanist Christian Gottfried Daniel Nees von Esenbeck. (CRC World Dictionary of Plant Names)

Eichhornia: for Johann Albrecht Friedrich Eichhorn (1779-1856), Prussian minister of education and public welfare, court advisor and politician. The genus was published in 1843 by German botanist Karl Sigismund Kunth. (CRC World Dictionary of Plant Names)

eichingeri: for Alfons Eichinger (1883-?), German botanist, collected in Tanzania around 1911-1916 and is commemorated with the former taxon Eragrostis eichingeri now synonymized to E. congesta. (Etymological Dictionary of Grasses)

eickii: for Emil Eick who collected in Tanzania around 1898-1899. The taxon in southern Africa that has this specific epithet is Manilkara eickii now synonymized to M. discolor.

eilyae: for Eily Edith Agnes Archibald (later Mrs. Gledhill) (1914-2007), botanist from Port Elizabeth, author of Eastern Cape Veld Flowers (1969), botany lecturer at Rhodes University and co-founder of the University herbarium, conducted a botanical survey of the Alexandria district, and founded a company to build low-cost housing. She is commemorated with Haworthia eilyae (now H. glauca). (JSTOR; Gunn & Codd)

Ekebergia: for Carl Gustav (Gustaf) Ekeberg (1716-1784), Swedish sea captain and explorer whose sponsor-
ship made it possible for the genus author, Swedish botanist Anders Sparrman whom he had met on a voyage to Canton in 1765, to visit Africa where he found and named Ekebergia capensis in 1779. Ekeberg trained as a chemist and physician and was a ship's doctor and expert navigator before becoming a captain, he was the author of Voyages aux Grandes-Indes dans les années, and was elected a fellow of the Swedish Academy of Sciences. He was an excellent cartographer and published precise maps of coastlines he had sailed (including that of the Cape) in his book Ostindiska Resa (Ostindische Reise in Den Jahren 1770 und 1771). He was also co-author of A Voyage to China and the East Indies. He made ten voyages to the Far East. The genus Ekebergia was published by Danish botanist, zoologist and physician Anders Sparrman in 1779. (CRC World Dictionary of Plant Names)

eksteeniae: for Dr. Dorothea Christina van Huyssteen, whose father, Dr. D.P. van Huyssteen, obtained plants of Lithops eksteeniae from her mother, Aletta Helena Eksteen, who first discovered it in 1935. Lithops eksteeniae is now L. dorotheae. It is not clear to me why the name should commemorate Dorothea Eksteen rather than the person who found it. (Etymology of Cacti and Succulent Species by John Chippindale; Women and Cacti)

elisabethiae: for Mrs. Elisabeth Schneider, plant collector of South Africa, commemorated with Lithops elisabethiae, originally published by Moritz Kurt Dinter and now synonymized to Lithops pseudotruncatella. (Women and Cacti)

elisae: for Miss J.J. Elisa van den Thoorn, secretary of The Netherlands Society of Succulent Plant Collectors 1935-1943, who made significant contributions to the development of the Society and its journal, Succulenta. She is commemorated with Lithops elisae. (Women and Cacti)

eliseae: for Mrs. Elise Bodley van Wyk (1922-1997), South African botanical artist, commemorated with Cotyledon eliseae. (Women and Cacti)

elishae: according to David Hollombe, "The first publication refers to 'M. G. Elisha" but other references give 'Mr. G. Elisha, Canonbury Park [Islington, London] Mesembryanthemums.' A George Elisha of 24 Canonbury Park, North Canonbury, died in 1921. He was a master house decorator, born in 1833." The taxon in southern Africa that bears this specific epithet is Conophytum elishae, published in 1922 by Nicholas Edward Brown..

elizae: the taxon in southern Africa that bears this specific epithet is Juttadinteria elizae, published in 1928 by South African botanist Harriet Margaret Louisa Bolus, with no information as to its derivation. May relate to the following entry.

elizeae: for Elize Esterhuizen, wife of J.M. ("Essie") Esterhuizen, commemorated with Haworthia elizeae. (All You Wanted to Know About Haworthias)

ellaphieae: for Johanna Ellaphie Ward-Hillhorst (1920-1994), cartographer, freelance commercial artist and botanical artist especially of succulents. She painted over 800 watercolors in 24 years, including 42 that were in The Flowering Plants of Africa, and frequently contributed to Bothalia, Veld and Flora, South African Journal of Botany and Cactus and Succulent Journal. She is commemorated with Tylecodon ellaphieae, Pelargonium ellaphieae, Diascia ellaphieae, and Gasteria ellaphieae. (Etymological Dictionary of Succu-
lent Plant Names)

ellenbergeri: for Rev. Rene Ellenberger (1873-1944) who collected Aloe ellenbergeri (recorded for some reason in the Plants of Southern Africa Checklist as Aloe ellenbergii) in Lesotho. He was the son of missionary D. F. Ellenberger, and was born in Lesotho and died in Johannesburg. This taxon, published by French botanist André Guillaumin, is now synonymized to Aloe aristata.

elliotii: for George Francis Scott-Elliot (1862-1934), Scottish botanist who collected in South Africa. "He worked as a botanist mainly in Africa and was employed on the French and English Delimination Commission of the Sierra Leone Boundary (1891-1892), also participating on the British East Africa Expedition or Ruwenzori Expedition (1893-1894). Scott-Elliott became a lecturer in Botany at the Royal Technical College, Glasgow (1896-1904) and was President of the Dumfries and Galloway Natural History and Antiquarian Society." He is commemorated with Moraea elliotii, Gladiolus elliotii, Metzgeria elliotii and Bulbophyllum elliotii (JSTOR; Elsa Pooley; Gunn & Codd; David Hollombe, pers. comm.).

elliottiana: for (1) Capt. George Henry Elliott, Jr. (1813-1892) of Farnborough Park, Hampshire, England, in whose garden Zantedeschia elliottiana grew from seed. Elliott died in Switzerland. (2) Mrs. F.W. (Friedrich Wilhelm) Kolbe (née Isabella Maria Elliott) (1830-1893), plant collector commemorated with the former taxon Mahernia elliottiana, published in 1862 by British botanist William Henry Harvey, and now synonymized to Hermannia elliottiana. She was the daughter of the Rev. William Elliott (see next entry) and the mother of the Monsignor Friedrich Carl Kolbe (1854-1936). She sent plants to Harvey in Dublin. (Gunn & Codd; David Hollombe, pers. comm.)

elliottii: for (1) William Allan Elliott (1851-1932), British Congregational missionary in Matabeleland, Zimbab-we 1877-1892, commemorated with Hemizygia elliottii (now synonymized to Syncolostemon elliottii) and Ipomoea elliottii (now synonymized to Ipomoea verbascoidea). (2) Charles Frederic Elliott (1847- 1911), Conservator of Forests in Kenya, previously deputy conservator in Baluchistan and Punjab, commemorated with Weihea elliottii (now synonymized to Cassipourea malosana)

Elphegea: I have no idea whether this epithet commemorates a specific person or not, but I will leave this entry here until I find out one way or another. The CRC World Dictionary of Plant Names says: "possibly referred to the Italian province of Emilia and its capital, Bologna, where Gian [Giovanni] Domenico Cassini (1625-1712) held the chair of astronomy at the University (1650-1669); or named after some unknown individual. Who knows? Maybe the name of a friend or member of the family." The genus was published in 1818 by Alexandre Henri Gabriel de Cassini for whom the genus Cassinia was named and who was a direct descendant of Giovanni Domenico Cassini, discoverer of the Great Red Spot of Jupiter and the Cassini division in Saturn's rings. (CRC World Dictionary of Plant Names; Wikipedia)

elsana: for Elsa Susanna Pooley (née Bond) (1947- ), South African botanist and accomplished botanical artist, author of The Complete Field Guide to Trees of Natal, Zululand & Transkei (1993), A Field guide to Wild Flowers of KwaZulu-Natal & the Eastern Region (1998) and Mountain Flowers, A Field Guide to the Flora of the Drakensberg and Lesotho (2003). She has also written many articles and contributed text and hundreds of illustrations for other works. She has collected plants, undertaken vegetation mapping studies, laid out botanical gardens and established a field herbarium for the Natal Parks Board research center. She is the
widow of Tony Pooley, who was a game ranger and world authority on crocodiles. Elsa Pooley was commem-
orated with the taxon Raphionacme elsana. (Women and Cacti)

elsiae/Elsiea/elsieae: for Elizabeth (‘Elsie’) Esterhuysen, (1912-2006), ‘the most outstanding collector ever
of South African flora.’ (Prof. Karel Bremer); she amassed 36,000 herbarium collections, many high-altitude species, and was a botanist at the Bolus Herbarium, the oldest functioning herbarium in South Africa established in 1856. The genus Elsiea was published in 1944 by South African botanist Frances Margaret Leighton, and E.E, Esterhuysen was also commemorated with many plant names, including taxa in Athanasia, Corymbium, Troglophyton, Hydroidea, Anderbergia, Trieenea, Hesperantha, Geissorhiza, Moraea, Watsonia, Mural-
tia, and Crassula, and probably a number of others. (Hugh Clarke, pers. comm.; CRC World Dictionary of Plant Names)

elskensii: for Octave Adrien Jean Elskens (1879-1935), plant collector in the Congo and Burundi, commemor-
ated with the former taxon Cycnium elskensii, which is now C. tubulosum, and which he collected in 1922.

emeliae/emelyae: for Mrs. Emily Pauline Reitz Ferguson (1872-?), a plant collector of Riversdale in South Africa who collected in the Riversdale and Swellendam areas in the 1920's and 1930's, commemorated with Haworthia emelyae and Gladiolus emeliae. See also fergusoniae.

emiliana: for Emily Haines Sloane (1886-1968), wife of American botanist and author Boyd Lincoln Sloane (1885-1955), commemorated with Duvalia emiliana.

engelianum: for a Dr. Engel who collected in Namibia in 1909 and who is a complete mystery to me, honored with the former Helichrysum engelianum, now H. cerastiodes. (JSTOR)

englerana/engleranus/Englerastrum/engleri/Engleria/engleriana/englerianum/englerianus/Englero-
daphne/Englerophytum: for Heinrich Gustav Adolf Engler (1844-1930), German botanist, professor at the University of Berlin and director of the Berlin Botanical Gardens, also founder and editor of the periodical Botanische Jahrbücher, notable for his work on plant taxonomy and phytogeography, author of many books and scientific papers. The genus Englerastrum was published in 1894 by Swiss botanist and plant collector John Isaac Briquet, Engleria was published in 1890 by German botanist Karl August Otto Hoffmann, Engler-
odaphne in 1894 by German botanist Ernest Friedrich Gilg, and Englerophytum in 1914 by German botanist Kurt Krause. (CRC World Dictionary of Plant Names)

englishiae: for Mrs. N. English (fl. 1917) who collected the type specimen of Prenia englishiae and is also commemorated with Mesembryanthemum englishiae and Aridaria englishiae. (Etymological Dictionary of Succulent Plant Names)

erckertii: for Friedrich von Erckert (1869-1908), German military officer, "father of the camel-riding troops" who served twice in German South-West Africa climaxed by his successful campaign against the rebellious Hottentots of Simon Kopper during which he was killed. The taxon in southern Africa that bears this specific epithet is Herniaria erckertii. (David Hollombe, pers. comm.)

erici-rosenii: for Count Carl Gustaf Bloomfield Eric von Rosen (1879-1948), Swedish Honorary doctor, patron, explorer and ethnographer. He participated in expeditions to Lappland, South America and the White Nile, and wrote successful books about them. I've encountered two stories involving Hermann Göring and von Rosen, one is that Göring married the sister of von Rosen's wife, and the other that he married his niece. I think the former is correct. His son Carl Gustaf Ericsson von Rosen was a pioneer aviator and flew combat missions for Finland and for the rebels in Biafra. The taxa in southern Africa which bear this specific epithet are Moraea erici-rosenii and Ficus erici-rosenii.

ernestianum: for Ernst Heinrich Friedrich Meyer (1791-1858), German professor and botanist whose herbar-
ium of 24,000 specimens was largely destroyed during World War II bombing. He is commemorated with Helichrysum ernestianum, now synonymized to H. sessile. In going back over these entries, I have been un-
able to find the source I originally used for this derivation, and thus it must for the time being be considered with a degree of caution. The isotype was collected in 1827 by Johann Franz Drège in the Camdeboosberg area of South Africa and the taxon name published in 1838 by Augustin Pyramus de Candolle.

ernesti-ruschii: for Ernst Julius Rusch (1867-1957), German-born farmer in Namibia and one of the founders of Windhoek. He came to South-west Africa as a soldier and stayed as a farmer, botanist, plant collector and succulent plant nurseryman. He made frequent collecting trips with his son Ernst Franz Theodor Rusch (1897-
1964), and the two of them were honored together with Lithops ruschiorum. Ernst Julius Rusch is also honored with the genus Ruschia, and with Hermannia ernesti-ruschii and Gasteria pillansii var. ernesti-ruschii and the former taxa Boophone disticha var. ernesti-ruschii (now B. haemanthoides) and Dipcadi ernesti-ruschii (now D. marlothii). (Etymological Dictionary of Succulent Plant Names; CRC World Dictionary of Plant Names)

ernestii: for Dr. Ernest E. Galpin (1858-1941), South African banker and incredibly prolific amateur botanist, Fellow of the Linnean Society and member of the South African Association for the Advancement of Science, commemorated with Euphorbia ernestii and Lampranthus ernestii, and at least six dozen taxa with the name galpinii. See also Galpinia/galpinii. (Gunn & Codd; Etymological Dictionary of Succulent Plant Names)

erniana/ernianum/ernii: for Franz Sales Erni (1878-1952), Swiss prospector, hotelier and farmer, became interested in succulent flora while on prospecting outings, after returning to Switzerland came back to South-
West Africa and Tanzania where he died. He is commemorated with Cephalophyllum ernii and the former taxa Lithops erniana (now L. karasmontana) and Conophytum ernianum (now C. taylorianum). (Gunn & Codd)

ernstii: for Ernst Jacobus van Jaarsveld (1953- ), collector and horticulturist first at Lowveld Botanic Garden in Nelspruit and then at Kirstenbosch, co-author of Gasterias of South Africa (1994), Flowers of Southern Africa (1995), Cotyledon and Tylecodon (2004) and Succulents of South Africa (2005). He is commemor-
ated with Conophytum ernstii, Eriospermum ernstii and Plectranthus ernstii. (Elsa Pooley; Gunn & Codd)

Eschscholzia: for Dr. Johann Friedrich Gustav von Eschscholtz (1793-1831), an Estonian surgeon, zoologist, entomologist and botanist who was with the Russian expeditions to the Pacific coast in 1816 and 1824 under the command of Otto von Kotzebue. On their first visit to the San Francisco region, his name was put on the pre-
viously undescribed California poppy by his friend and companion the German poet and botanist Adelbert von Chamisso, and subsequently on dozens of other newly discovered flowers. Later he returned the favor by naming a lupine after his friend, Lupinus chamissonis. He was the author of System der Akalephen (1829) and the Zoologischer Atlas (1829–1833). Kotzebue named an island in the Marshall chain Eschscholtz Atoll, but it has become more familiar to us by its subsequent name, Bikini. Eschscholtz was only 38 when he died. The genus Eschscholzia was actually published in 1820. (CRC World Dictionary of Plant Names)

estelleana: for Mrs. Estelle Bayliss (née Dell) (fl. 1960-1968), wife of Lt. Col. Roy Douglas Abbot Bayliss (1909- ) and accompanied him on several of his shorter collecting excursions, made the second collection of Brachystelma campanulatum. She collected the holotype of Ceropegia estelleana in 1963 in the Fish River Valley. It has since been synonymized to C. fimbriata. (Gunn & Codd)

esterae: for Ester Chodat, sister of the author of Polygala esterae, Robert Hippolyte Chodat (1865-1934), Swiss botanist and phycologist who was a professor and director of the botanical institute at the University of Geneva and a leading authority on Polygalaceae. (David Hollombe, pers. comm.)

esteriana: the taxon in southern Africa that bears this specific epithet is Erica esteriana, published in 1987 by South African botanist Edward George Hudson Oliver, with no information as to its derivation.

esterhuizenii: for J.M. ("Essie") Esterhuizen (fl. 1997-2003), plant collector in South Africa, husband of Elize Esterhuizen, commemorated with Haworthia esterhuizenii.

Esterhuysenia/esterhuyseniae: for Elsie Elizabeth Esterhuysen, (1912-2006), ‘the most outstanding collector ever of South African flora.’ (Prof. Karel Bremer); she amassed 36,000 herbarium collections, many high-
altitude species, and was a botanist at the Bolus Herbarium, the oldest functioning herbarium in South Africa established in 1856. In addition to the specific epithets elsiae and elsieae named for her, the epithet esterhuy-
seniae is on taxa in Aridaria, Delosperma, Erepsia, Gibbaeum, Lampranthus and Ruschia. The genus Est-
erhuysenia was published for her in 1967 by South African botanist Harriet Margaret Louisa Bolus. (Hugh Clarke, pers. comm.; CRC World Dictionary of Plant Names)

etaylorii: the taxon iin southern Africa that bears this specific epithet is Conophytum etaylorii, published in 1929 by German botanist Martin Heinrich Gustav Schwantes, with no information as to its derivation.

etheliae: for Ethel Bolus (1866-1890), South African plant collector who was the discoverer of the species Bartholina etheliae, also commemorated with Erica etheliae. She was the daughter of Harry Bolus. (Hugh Clarke, pers. comm.)

ettae: for Miss Etta Stainbank (later Mrs. English). No idea what her dates were or whether she was related to Henry Ellerton Stainbank (1836-1915) whose wife's name was Eliza Stainbank (née Munro). One curiosity is that H.E. Stainbank was born in Peckham, Surrey, and I found an online reference to a mortgage taken out in 1878 by Richard Henry Stainbank and Eliza Stainbank for a property in Peckham, Surrey. May be just a coin-
cidence.

eugene-maraisii: for Eugène Nielen Marais (1871-1936), South African lawyer, writer and naturalist, and one of the greatest of the Afrikaaner poets, commemorated with Encephalartos eugene-maraisii.

Eugenia: for Prince Eugene of Savoy (1663-1736), French-born book collector and patron of botany, one of the greatest of the Austrian Hapsburg generals. He distinguished himself in many campaigns, most notably against the Turks who were besieging Vienna, again against the Turks after they recaptured Belgrade, and against the French in Italy and Provence during the War of Spanish Succession. He was the only person whose name has been given to warships of four different navies, British, Austro-Hungarian, German and Italian. The German heavy cruiser Prinz Eugen operated alongside the battleship Bismarck when the latter sank HMS Hood in the Battle of the Denmark Strait. The genus Eugenia was published by Swedish botanist Carl Linnaeus in 1754. (CRC World Dictionary of Plant Names)

Eulalia: for Eulalie Delile (1800-1840), botanical artist who illustrated the work of the French naturalist Victor Jacquemont. She was the sister of French botanist Alire Raffeneau Delile (1778-1850). The genus Eulalia was published by German botanist Carl Bernhard von Trinius in 1833. (CRC World Dictionary of Plant Names)

Eupatorium: for Mithridates VI (134-63 BC), also known as Eupator Dionysius, King of Pontus and Armenia Minor of Greek and Persian origins, who is said to have discovered in one of the species an antidote to a commonly used poison. He was one of the most successful enemies of the Roman empire having engaged the great generals Sulla, Lucullus and Pompey the Great in the Mithridatic Wars. It is also possible that the species he discovered was itself poisonous and that he took regular small doses of it to build up his tolerance. He was notoriously paranoid about being poisoned and fashioned several complex so-called universal antidotes which he ingested every day as a means of avoiding being poisoned. The genus was published in 1753 by Swedish botanist Carl Linnaeus. (CRC World Dictionary of Plant Names)

Euphorbia: for Euphorbus, Greek physician of Juba II, King of Mauretania. Juba was educated in Rome and married the daughter of Antony and Cleopatra. He was apparently interested in botany and had written about an African cactus-like plant he had found or which he knew about from the slopes of Mt. Atlas which was used as a powerful laxative. That plant may have been Euphorbia resinifera, and like all Euphorbias had a latexy exudate. Euphorbus had a brother named Antonius Musa who was the physician to Augustus Caesar in Rome. When Juba heard that Caesar had honored his physician with a statue, he decided to honor his own physician by naming the plant he had written about after him. The word Euphorbus derives from eu, "good," and phorbe, "pasture or fodder," thus giving euphorbos the meaning "well fed." Some sources suggest that Juba was amused by the play upon words and chose his physician's name for the plant because of its succulent nature and because of Euphorbus' corpulent physique. The genus was published in 1753 by Swedish botanist Carl Linnaeus. (CRC World Dictionary of Plant Names)

eustacei: for Charles Eustace Pillans (1850-1919), South African horticultural assistant of the Department of Agriculture in the Cape of Good Hope colony, author and plant collector who at the time of his discovery of Euphorbia eustacei was Director in the Cape Government service and keen collector of Cape succulents, father of Neville Stuart Pillans. He is commemorated with Erica eustacei and Euphorbia eustacei. (David Hollombe, pers. comm.)

evansiana/evansii: for Maurice Smethurst Evans (1854-1920), British-born South African businessman, politician and plant collector in Kenya, Uganda and South Africa. He came to Natal in 1875 and was co-author with John Medley Wood of Natal Plants. He was a member of parliament and is commemorated with Indigo-
fera evansii, Kniphofia evansii, Euphorbia evansii, Euryops evansii, Helichrysum evansii and the former taxa Senecio evansii (now Heteromma decurrens) and Philippia evansii (now Erica evansii). There are also the taxa Indigofera evansiana and Lotononis evansiana in southern Africa, but I'm not sure who they are for. (Elsa Pooley; JSTOR; Gunn & Codd).

evelynae: for the mother of the author Reinhold Conrad Muschler, named Evelyne, commemorated with Senecio evelynae. The taxon was published in 1909. (David Hollombe, pers. comm.)

exleeana: for James Lee (1715-1795), Scottish nurseryman, commemorated with Erica exleeana, formerly Philippia leeana, a taxon named by Ted Oliver.

eylesii: for Frederick Eyles (1864-1937), English journalist, miner, farmer, government botanist who collected in Zambia and Zimbabwe and is commemorated with the taxa Euphorbia eylesii, Digitaria eylesii, Pavetta eylesii, and the former taxa Rhynchelytrum eylesii (now Meliinus subglabra), Sporoblus eylesii (now S. congoensis), Tristachya eylesii (now T. nodiglumis), Hyparrhenia eylesii (now Elymandra grallata), Lissochilus eylesii (now Eulophia angolensis), Aspilia eylesii (now Melanthera albinervia) and Euclea eylesii (now E. linearis). (Etymological Dictionary of Succulent Plant Names; JSTOR)

fabricii: for Friedrich Wilhelm Peter Fabricius (1742-1817) who received a medical doctorate from the Uni-
versity of Edinburgh in 1767 with the thesis Tentamen medicum inaugurale, de emetatrophia. He was also co-author of Disputatio medica de motu humorum progressivo veteribus non ignoto (1762). The taxon in southern Africa with this specific epithet is Lapeirousia fabricii, published in 1809 by British botanist John Bellenden Ker Gawler. (David Hollombe, pers. comm.)

Fagelia: for Hendrik Fagel the Elder (1706-1790), 2nd Greffier of the Dutch Staten-Generaal (States-General or parliament) (1742-1744), 1st Greffier of the Dutch Staten-Generaal (1744/1790). A greffier is an adminis-trative position somewhat equivalent to a secretary of state. He met and was acquainted with the diarist James Boswell. He also knew the Dutch explorer of South Africa Robert Jacob Gordon and received many letters from him containing long accounts of his expeditions with many ethnographic, geographic and zoologic details. Upon his death Hendrik Fagel the Younger inherited both his book collection and his position. Then there was a hendrik Fagel III (1765-1838) who was also greffier. The genus Fagelia was published in 1774 by Dutch botanist Martinus Wilhelmus Schwencke. (CRC World Dictionary of Plant Names; The Standard Cyclopedia of Horticulture by L.H. Bailey; David Hollombe, pers. comm.)

Fagonia: for Guy-Crescent Fagon (1638-1718), French botanist, chemist, patron of botany, chief physician to Louis XIV, professor of botany at the Paris Jardin du Roi, 1671-1708, and from 1699 to 1718 its director. The genus was published in 1753 by Swedish botanist Carl Linnaeus. (CRC World Dictionary of Plant Names)

Faidherbia: several sources I found said that this is named for Louis Léon César Faidherbe (1818-1889), French general and Governor of Senegal, and I haven't found anything to the contrary, but this remains to be confirmed. An article in Wikipedia states that: "For his military services he was decorated with the grand cross, and made chancellor of the order of the Legion of Honor. In 1872 he went on a scientific mission to Upper Egypt, where he studied the monuments and inscriptions. An enthusiastic geographer, philologist and archae-
ologist, he wrote numerous works, among which may be mentioned Collection des inscriptions numidiques (1870), Epigraphie phenicienne (1873), Essai sur la langue poul (1875), and Le Znaga des tribes séné-
galaises (1877), the last a study of the Berber language. He also wrote on the geography and history of Senegal and the Sahara, and La Campagne de l'armée du Nord (1872)." The genus was published in 1934 by French botanist, taxonomist and explorer of tropical Africa Auguste Jean Baptiste Chevalier. (Wikipedia)

fairii: for Charles Bass Fair (1840-1907), member of the Cape Colonial Civil Service, friend of Harry Bolus. Mr. Fair discovered Erica fairii in 1892 amongst rocks on top of mountains near Simonstown, and Bolus published the name in 1894. (Hugh Clarke, pers. comm.; Journal of Botany, British and Foreign)

Falkia/falkia: for Johan Peter Falck (Falk) (1733-1774), Swedish botanist and doctor, traveller, professor of botany at St. Petersburg, and pupil of Linnaeus. He accompanied Linnaeus on his expedition to the island province of Gotland and tutored Carl Linnaeus the younger. He undertook an expedition at the behest of the Russian Academy of Sciences to explore a vast area of Siberia during which he collected a great deal of infor-
mation about plants, animals and local peoples and customs. He committed suicide in Kazan after having be-
come addicted to opium and enduring long spells of depression. The genus was published in 1781 by Swedish botanist Carl Peter Thunberg. He was also honored with the name Convolvulus falkia. (CRC World Diction-
ary of Plant Names; A General System of Gardening and Botany by George Don)

Fallopia: for Gabriele Falloppio (1523-1562), Italian anatomist, physician, and professor of anatomy who dis-
covered the tubes that connect the ovaries to the uterus. He occupied the chair of anatomy and surgery at the University of Padua, was professor of botany,and superintendent of the botanical gardens. He was considered one of the great anatomists of his time. The genus Fallopia was published by French botanist Michel Adanson in 1763. (CRC World Dictionary of Plant Names)

Fanninia/fanninii: for George Fox Fannin (1832-1865), Irish botanist, plant collector and farmer who died at an early age in Natal. After moving to South Africa he became interested in the local plants and collected many which he sent to Irish botanist William Henry Harvey at Dublin. His sister Marianne Edwardine Fannin (later Mrs. M.E. Roberts), who also lived in South Africa, painted and pressed many of these collected specimens. The genus was published in 1868 by Irish botanist William Henry Harvey. He is also commemorated with the taxon Anenome fanninii, which he first collected in 1863 at his farm in Dargle, KwaZulu-Natal. (CRC World Dictionary of Plant Names; Gunn & Codd)

fanniniae: for Marianne Edwardine Roberts (née Fannin) (1845-1938), artist who pressed and painted plants collected by her brother G.F. Fannin. Also the mother of noted ornithologist Austin Roberts. She is commemor-
ated with Disperis fanniniae, Streptocarpus fanniniae, and the former taxa Disa fanniniae (now D. nervosa) and Brownleea fanniniae (now B. galpinii). There are also the current taxon Sisyranthus fanniniae and the former taxon Satyrium fanniniae (now S. bracteatum) that were probably named for her as well. (Elsa Poo-
ley; Gunn & Codd)

fanshawei: for Dennys Basil Fanshawe (1915-1993), plant collector who worked in Zambia who has important collections at the University of Zambia Herbarium, and is commemorated with Ipomoea fanshawei. (JSTOR)

Faurea: for William Caldwell Faure (1822-1844), South African botanist, soldier and naturalist, teacher of mathematics at South African College, went to India for the East India Co. and became an Ensign in the 2nd European Light Infantry, died in an ambush at the early age of 22. The genus Faurea was named in 1847 by Irish botanist William Henry Harvey, who complimented Faure's knowledge of Cape plants and predicted that had he lived he would have become a fine botanist. (CRC World Dictionary of Plant Names; Gunn & Codd)

feddeanum: for Friedrich (Friderico) Karl Georg Fedde (1873-1942), German botanist and plant name author who described many plants. He was an associate at the Berlin Botanical Museum and later a professor there.
He was the author of and known mainly for the work Repertorium Specierum Novarum Regni Vegetabilis (1907). The taxon in southern Africa that formerly had this specific epithet was Aptosimum feddeanum, pub-
lished by German botanist Robert Knud Friedrich Pilger, now synonymized to A. glandulosum. He is also honored with genus Feddea, which is not in southern Africa.

Felicia: the entry in CRC World Dictionary of Plant Names well illustrates the difficulty of figuring out some of these derivations, to wit: "Possibly after a German official, possibly in Regensburg, possibly a certain Herr Felix, possibly d. 1846; or from the Latin felix, licis "happy, cheerful" [a reference to the bright flowers]; or for the Italian Fortunato Bartolomeo de Felice (1723-1789)." The name was given by French botanist and naturalist Alexandre Henri Gabriel de Cassini in 1818 and must for the moment remain essentially unexplained.

Felipponea: possibly for Dr. Florentino Felippone (1849-1939), botanist and bryologist from Uruguay. This is a generic epithet considered by Tropicos to have been invalidly published.

felixii: possibly for Henri Jacques-Felix (1907-2008), French botanist and plant collector. The taxon in southern Africa with this epithet is the former Ophioglossum felixii, published in 1948 by French botanist Marie Laure Tardieu, now synonymized to Ophioglossum costatum.

fenarolii: probably for Luigi Fenaroli (1899-1980), Italian botanist, agronomist and plant collector in Angola and Brazil. He was Vice-Director of the Forestry Experimental Station in Florence, junior professor at the Faculty of Agriculture at the University of Milan, produced some 275 publications, on subjects such as phyto-
geography, systematic botany, forestry, flora and nature conservation, visited Egypt, Japan, Canada and the United States, and taught at the University of Milan and elsewhere. The taxon in southern Africa with this spe-
cific epithet is Chamaecrista fenarolii which was collected in Angola and published by British botanist John Michael Lock in 1988.

fenchelii: for Tobias Fenchel (1844-1910), missionary in Keetmanshoop (Namibia), plant collector, commem-
orated with the former taxon Mesembryanthemum fenchelii, now synonymized to M. guerichianum. (Gunn & Codd)

fendleri: for August(us) Fendler (1813-1883), German-American plant collector in North and Central America. He came to the United States in 1836 and worked at a variety of occupations, and essentially became an itinerant traveller from New York to St. Louis, then to New Orleans and Texas and back to Illinois. Whenever he arrived somewhere, he seemed to almost immediately want to go somewhere else. He returned to Germany, but discovered the financial potential of dried plant specimens, so with the assistance of George Engelmann and Asa Gray, he set about collecting, enduring unfortunate events such as losing his drying papers in a flood and his collections, notes and journals in the great fire of 1849 in St. Louis. He went to Panama and Venezuela and made large collections from there. Rheumatism forced him to seek a warmer climate and he and his brother went to Trinidad in 1877 where he lived until his death. He was an accomplished and prolific plant collector and was also interested in physics and meteorology, but his book The Mechanism of the Universe, was not a success. Engelmann and Gray did name the genus Fendlera for him, but in southern Africa he is commemorated with the taxon Arenaria fendleri, also published by Gray.

fenzelianus: probably for Eduard Fenzl (1808-1879), Austrian physician and botanist, head of the botanical department of the Vienna Natural History Museum, professor of botany and then head curator of the museum. He was a member of the Viennese Academy of Sciences and vice president of the Horticultural Society. The taxon in southern Africa with this epithet is the former Cyperus fenzelianus, published in 1854 by German physician and botanist Ernst Gottlieb von Steudel, now synonymized to Cyperus rotundus. (Wikipedia).

Feretia: for A. Ferret, French plant collector active in Ethiopia1839-43. This is likely to be the Captain Pierre Victor Ad Ferret who with Joseph Germaine Galinier published Voyage en Abyssinie in 1847. The genus was published in 1843 by French botanist Alire Raffeneau Delile. (Sappi What's In a Name: The Botanical Meanings of the Names of Trees by Hugh Glen; Origins and Meanings of Names of South African Plant Genera by W.P.U. Jackson; IPNI)

fergusoniae: for Mrs. Emily Pauline Reitz Ferguson (1872-?), a plant collector of Riversdale in South Africa who collected in the Riversdale and Swellendam areas in the 1920's and 1930's. She is commemorated with the taxa Lampranthus fergusoniae, Antimima fergusoniae, Pelargonium, Trichodiadema fergusoniae, Glottiphyllum fergus-oniae and Watsonia fergusoniae and possibly for other taxa in Freesia, Moraea,and Cyrtanthus. (Etymological Dictionary of Succulent Plant Names)

Ferraria: for Giovanni Battista Ferrari (1584-1655), Italian botanist, entered the Jesuit order in Rome in 1602, was a professor of Hebrew and Rhetoric at the Jesuit College in Rome, and held a position as horticultural advisor to the papal family. He was the author of many illustrated botanical books including De Florum Cultura in 4 vols. (1633) devoted to the planning and planting of gardens, and was the first scientist to provide a com-
plete description of the limes, lemons and pomegranates and their use in preventing scurvy. The genus was pub-
lished in 1759 by Dutch botanist and physician Johannes Burman. (CRC World Dictionary of Plant Names)

Ficinia: for Heinrich David Auguste Ficinus (1782-1857), German botanist, physician, naturalist and professor of physics and chemistry. He wrote several literary works and textbooks in the fields of botany, optics and mineral chemistry. The genus was published in 1832 by German botanist Heinrich Adolph Schrader. (CRC World Dictionary of Plant Names)

filarszkyana: for Dr. Nandor Filarszky (1858-1941), Hungarian botanist, director of the botany department at the National Museum in Budapest, specialist in phycology, plant morphology, and plant systematics, co-author of Kaukasus: Reisen und Forschungen im kaukakischen Hochgebirge, commemorated with Xanthopar-
melia filarszkyana.

Finckea: for August Fincke (1805-1873), Polish pharmacist and botanist of Silesia who took over the Apothecary in Krappitz in 1836. He was interested in researching the flora of upper Silesia. The genus was published in 1838 by German botanist Johann Friedrich Klotzsch. (The Treasury of Botany by John Lindley and Thomas Moore).

finckei: for an H. Fincke, German apothecary in Namibia. There are taxa in southern Africa with this specific epithet in the genera Catillaria, Lecidea, Acarospora and Dermatocarpon. (David Hollombe, pers. comm.)

Fingerhuthia: for Carl (Karl) Anton Fingerhuth (1798-1876), German botanist and physician, author of Mono-
graphia Generis Capsici (1832) and Tentamen florulae lichenum Eiffliacae (1829), and co-author with Matthias Joseph Bluff and Karl Friedrich Wilhelm of Compendium florae Germaniae. The genus was pub-
lished by German botanist Christian Gottfried Daniel Nees von Esenbeck in 1834. (CRC World Dictionary of Plant Names)

Fintelmannia: likely for Gustav Adolph Fintelmann (1803-1871), German gardener for King Frederick William III, also worked as animal keeper for the menagerie on Pfaueninsel (Peacock Island) in the Havel River between Berlin and Potsdam. He was also the Royal Gardener at Wilhelmshöhe Palace above the city of Kassel, a position his family had held for generations. He was the author of Über Nutzbaumpflanzungen (1856). The genus was published in 1837 by German botanist Karl (Carl) Sigismund Kunth.

fionae: for Fiona Mary Getliffe Norris (1941- ), the PhD supervisor of Professor Kevin Balkwill, Head of School of Animal, Plant and Environmental Sciences, University of the Witwatersrand. She was Lecturer in botany at the University of Durban-Westville and Senior Lecturer at Witwatersrand University, emigrated to the U.S. after she married Richard E. Norris of California, and is commemorated with Dicliptera fionae. (Kevin Balkwill, pers. comm.; Gunn & Codd)

fischeri/fischerianum: for Dr. Gustav Fischer (1848-1886), German doctor, explorer, and naturalist who col-
lected in Tanzania, commerorated with Rothmannia fischeri, Tapura fischeri, and Ficus fischeri. (Flora of Zimbabwe)

Flacourtia: for Étienne de Flacourt (1607-1660), botanist and traveller, Director of the French East India Company, Governor of Madagascar 1648-1655, author of Histoire de la Grande Isle Madagascar (1658), and one of the first Europeans to describe the elephant bird, Aepyornis maximus. The genus was published in 1786 by French botanist Charles Louis L'Héritier de Brutelle. (CRC World Dictionary of Plant Names)

Flanagania/flanaganii: for Henry George Flanagan (1861-1919), a prolific South African-born collector and traveller. Flanagan also owned Prospect Farm in the Komga District of Eastern Cape, where he developed a noteworthy garden containing rare exotics as well as South African trees and shrubs. The genus Flanagania was published in 1894 by German taxonomist and botanist Friedrich Richard Rudolf Schlechter. Flanagan was also honored by having his name attached to many genera including Euphorbia, Glumicalyx, Manulea, Selago, Greyia, Gladiolus, Cassipourea, Hypoxis, Erica, Cyrtanthus, Abutilon, Tylophora, Aspidoglossum, Raphionacme, Mystacidium, Corycium, Felicia, Senecio, Helichrysum, Vernonia, Scolopia, Crassula, Ecbolium and others. (PlantzAfrica; Etymological Dictionary of Succulent Plant Names)

flanaganiae: for Florence Reynolds (Mrs. Henry George) Flanagan, who discovered Impatiens flanaganiae in the Eastern Cape.

fleckii: for Dr. Eduard Fleck (fl. 1890), German geologist and plant collector in South Africa, sent to South-
West Africa in 1888 by Deutschen Kolonialgesellschaft, crossed the Kalahari in 1890. He is commemorated with Acacia fleckii, Acrotome fleckii, Hermbstaedtia fleckii, Tylophora fleckii and probably with taxa in the genera Rhynchosia, Jamesbrittenia, Nemesia, Hibiscus, Albuca and Blepharis. (Gunn & Codd; Etymolo-
gical Dictionary of Grasses)

Flemingia: for Dr. John Fleming (1747-1829), English botanist and physician, member of the Indian Medical Service in Bengal, Physician-general and President of the Bengal Medical Board, Fellow of the Royal and Linnean Societies, the Royal Society of Edinburgh and the Horticultural Society, and author of Catalogue of Indian Medical Plants and Drugs (1810). He also made a large collection of drawings done by native artists of Indian plants. He entered the Indian Medical Service in 1768, became a surgeon in 1771, and a member of the Medical Board in 1786. He remained in the Service until his retirement in 1813, when he returned to England. He had corresponded with Sir Joseph Banks and had sent him specimens for his collection, and became a member of the Medico-Botanical Society of London. In 1818 he was elected a Member of Parliament, a posi-
tion he held for only two years. This epithet is a good example of the confusion surrounding some of these names, to wit: (1) The CRC World Dictionary gives John Fleming (1747-1829), English botanist of the Indian Medical Service; (2) The Leguminosae by Ethel Kullman Allen gives Dr. John Fleming, Scottish naturalist and Physician-General of the East India Company's Medical Establishment in Bengal; (3) There was a Scottish naturalist of this name with the dates 1785-1857 but according to Wikipedia he had nothing to do with India; (4) Trees and Shrubs of Mpumalanga and Kruger National Park gives John Fleming (1785-1857), doctor and botanist; (5) The Dictionary of National Biography, Vol. 19, by Sir Leslie Stephen and Sir Sydney Lee, gives John Fleming, doctor and botanist, died 1815; (6) The website Indianetzone: History of India says John Fleming (1770-1829) of the East India Company`s Medical Service, and this is repeated in The History of British India: A Chronology by John Riddick; (7) Wikipedia has John Fleming (1747-1829) as a British politician and MP, but says nothing at all about his career in India; (8) The Western Antiquary of 1888-1889 edited by W.H.K. Wright gives 1827 as his death date. What this all boils down to is that the person honored here is Bri-
tish botanist John Fleming (1747-1829), and the Scottish naturalist named John Fleming (1785-1857) was the one for whom the genus of fossil plants Flemingites was named. The genus Flemingia in the Fabaceae was published in 1812 by Scottish botanist William Townsend Aiton after it had originally been named by Scottish botanist and surgeon William Roxburgh, called the 'Father of Indian Botany,' as a tribute to Fleming because of his knowledge of Indian plants. (CRC World Dictionary of Plant Names; Journal of Botany - History of the Indian Medical Service.)

Fleurya: one source says this was dedicated to the French plant collector Francis Fleury (1882-1919) who died during an expedition to India and Malaya, however the name was published in 1830 by French botanist Charles Gaudichaud-Beaupré so that's not possible. A second source, Thesaurus literaturae botanique omnium gentium by George August Pritzel, states that the genus is named after a J.F. Fleury (fl. 1819), a French botanist and writer on orchids, which attribution is repeated in The Century Supplement to the Dict-
ionary of Gardening, Vol. 10, by George Nicholson, A Flora of Manila by E.D. Merrill and The Bahama Flora by Nathaniel Lord Britton. But according to information unearthed by David Hollombe, Charles Gaudi-
chaud-Beaupré named a number of new genera after officers involved in the 1817-1820 circumglobal expedition on which he sailed as botanist, among whom was a Camile Fleury, so this would seem to be a much greater likelihood for the derivation of this epithet. This accords with An Etymological Dictionary of Australian Plant Genera, which says that the genus was named for C. Fleury, a merchant service apprentice on the Uranie, one of the two ships involved in the expedition. And since the genus was published in Gaudichaud's description of the expedition Voyage autour du Monde, entrepris par Ordre du Roi, . . . Execute sur les Corvettes de S.M. l'Uranie et la Physicienne . . . par M. Louis de Freycinet, this commemoration makes sense. Fleury was listed in this work as a member of the crew and was elevated to the rank of ensign during the course of the expedition.

floerkeana: for Heinrich Gustav Flörke (Floerke) (1764-1835), German lichenologist, professor of botany, author of De Cladoniis Difficillimo Lichenum Genere Commentatio Nova, and co-author of Oekonomische Encyclop, commemorated with the taxon Cladonia floerkeana.

flotowii: for Dr. Julius Christian Gottlieb Ulrich Gustav Georg Adam Ernst Friedrich von Flotow (1788-1856), German military officer, lichenologist, moss specialist, author of Über Haematococcus Pluvialis (1844) and Lichenes Florae Silesiae (1849-1850), commemorated with the former taxon Usnea flotowii, synonymized to U. maculata.

Flueggia: for Johann(es) Flüggé (Fluegge) (1775-1816), German physician, cryptogamic botanist, university lecturer, established the first botanical garden in Hamburg in 1810, did research on grasses. The genus was published in 1883 by British botanists George Bentham and Joseph Dalton Hooker. (CRC World Dictionary of Plant Names)

Fockea: for Gustav Waldemar (Woldemar) Focke (1810-1877), German physician of Bremen, plant physiolo-
gist, amateur microscopist and author of De respiratione vegetabilium (1833) and Physiologische Studien (1847). The genus was published in 1839 by Austrian theologian and botanist Stephan Friedrich Ladislaus Endlicher. (CRC World Dictionary of Plant Names).

foermeriana: probably for Rudolf Förmer (Foermer) (fl. 1900-1901), German botanist, soldier in a regiment sent to South-West Africa, collected in Namibia. The taxon in southern Africa with this specific epithet is the former Geigeria foermeriana, now G. plumosa, which was collected in Namibia. (Etymological Dictionary of Grasses; Gunn & Codd)

foleyana/foleyi: for Mr. W.J. Foley (fl. 1916-1918), of the South African Museum Herbarium, then of the National Herbarium in Pretoria, plant collector in South Africa, commemorated with Bulbine foleyi and Pteronia foleyi. (Etymological Dictionary of Succulent Plant Names; Gunn & Codd)

fontanesianum: for René Louiche Desfontaines (1750-1833), French botanist, member of the French Acad-
emy of Sciences, spent two years in Tunisia and Algeria, author of Flora Atlantica in two volumes which included 300 genera new to science, professor of botany at the Jardin des Plantes, Director of the Muséum National d'Histoire Naturelle. (Etymological Dictionary of Grasses; Wikipedia)

Forbesia/forbesiana/forbesianum/forbesii: for John Forbes (1799-1823), an English plant collector and naturalist who visited the Cape in 1822 having been appointed by the Horticultural Society of London, and died on the Zambesi River in Mozambique the following year. The expedition under the command of Captain William Owen aboard the Leven sailed from England to Lisbon, Madeira, and the Cape Verde Island, then to Rio de Janeiro and across to the Cape of Good Hope, then to Port Elizabeth and to Delagoa Bay in Mozambique, where almost a third of the crew died of malaria. They went on to Madagascar and the Comoro Islands before returning to the Cape. After John Forbes died in 1823 the expedition continued to the Seychelles, Mauritius, Bombay and Muscat, eventually drawing some 300 charts and mapping almost 30,000 miles of the African coastline. The Harvard University Herbarium database gives his year of birth as 1798, but other sources say 1799. The genus Forbesia was published in his honor in 1827 by Danish botanist Christian Friedrich Ecklon. Gunn & Codd give three taxa that commemorate John Forbes, Amaryllis forbesii, Grewia forbesii, and Loranthus forbesii, but each of these taxa is either not in southern Africa, not a current taxon or not validly published. He was also commemorated with Nymphoides forbesiana, found in Mozambique, and Arctotheca forbesiana. Tapinanthus forbesii, Albizia forbesii and Dichrostachys forbesii were collected by a Forbes at Delagoa Bay, so they probably honor him, as well as Striga forbesii, collected in Mozambique with no location record. Others such as Dicerocaryum forbesii, Tephrosia forbesii, Aspalathus forbesii, Selago forbesii and Melhania forbesii must remain uncertain for now. Other possible individuals with this name who may or may not be honored with such specific names as forbesiana, forbesianum and forbesii are Edward Forbes (1815-
1854), British naturalist, curatorship of the museum of the Geological Society of London, Professor of Botany at King's College, Professor of Natural History at the University of Edinburgh, and co-author of A History of British Mollusca, Henry Ogg Forbes (1851-1932), Scottish naturalist and collector, commemorated with Aloe forbesii, not in southern Africa, Helena Madelain Forbes (1900-1959), Scottish botanist who worked in South Africa and at Kew Gardens, and John Forbes Royle (1799-1858), British physician. (Dictionary of National Biography)

fordii: for Charles Ford (1844-1927), British botanist, plant collector in China and Formosa, recommended by Joseph Hooker to be superintendent of the Botanical and Afforestation Department in Hong Kong, created the Hong Kong Botanic Gardens, commemorated with Vernicia fordii. (CRC World Dictionary of Plant Names)

forresteri: there is a JSTOR specimen record for Conophytum forresteri being collected by H.J. Forrester in Nieuwefontein, South Africa in 1936, so I presume this is who it is named for.

forrestii: for George Forrest (1873-1932), Scottish botanist and prolific plant collector, studied apothecary arts in Scotland, then sheepherding in Australia, before turning to horticulture, often considered the greatest of all collectors of rhododendrons. He is credited with introducing hundreds of species from China and Tibet to the Edinburgh Botanic Garden, many plants have been named for him. He spent 28 years in northern China and survived attacks by Tibetan guerillas and other dangers such as having a bamboo spike completely pierce his foot. He apparently was snipe shooting when he complained of chest pains and jumped up to fire, at which time both he and the snipe fell dead. He collected over 30,000 herbarium specimens and is commemorated with the name of the taxon in southern African Hypericum forrestii. (Information from a wonderful webblog called 'The Mysterious Garden Muse' and Plant Names Explained: Botanical Terms and Their Meanings)

forskahlii/forskalii/forskaolii/Forsskaolea: for Pehr Forsskål (1732-1763), Finnish-born Swedish botanist and zoologist, botanical traveller in Egypt and Arabia, plant collector and pupil of Linnaeus, author of Flora aegyptiaco-arabica (1775), naturalist on the Royal Danish expedition to Egypt and Yemen 1761-1763 where he died from malaria. The Danish botanist Carsten Niebuhr who went on this expedition as geographer was the sole survivor. The genus Forsskaolea was published by Swedish botanist Carl Linnaeus in 1764. He was also commemorated with Commelina forskaolii which he collected in Arabia, Mesembryanthemum forskahlii, and .probably Hypoestes forskaolii and the former taxa Euphorbia forskalii (now E. austro-occidentalis) and Danthonia forskalii (now Centropedia glauca). In Zambia there is a species called Helichrysum forskahlii which has the common name Forskahl's everlasting. (CRC World Dictionary of Plant Names; Wikipedia)

Forsstroemia: for Johan Erik Forsström, Swedish pastor and collector. The genus was published in 1863 by Swedish-Finnish bryologist Sextus Otto Lindberg.

forsteri: for Prof. Johann Reinhold Forster (1729-1798) of Halle University, German naturalist and Lutheran pastor who moved to England in 1766, author of A Catalog of British Insects (1770) and Observations Made during a Voyage round the World (1778), elected a Fellow of the Royal Society in 1772, and/or his son Johann Georg Adam Forster (1754-1794), naturalist, ethnologist, travel writer, journalist, and revolutionary, taught natural history and became the head librarian at the University of Mainz, author of A Voyage round the World in His Britannic Majesty's Sloop Resolution, Commanded by Capt. James Cook, during the Years, 1772, 3, 4, and 5 and Views of the Lower Rhine, from Brabant, Flanders, Holland, England, and France in April, May and June 1790. Both father and son accompanied Captain Cook on his second Pacific journey (1772-1775) as expedition naturalists. In 1779 Forster the elder was appointed Professor of Natural History and Mineralogy at the University of Halle, and director of the Botanische Garten der Martin-Luther-Universität Halle-Wittenberg, a position he held until his death. The taxon in southern Africa that formerly had this specific epithet was Drimia forsteri, now synonymized to D. capensis. J. Forster and J.G.A. Forster are listed as plant authors of Drimys winteri. (Dictionary of Australian Biography; Gunn & Codd)

fosteri: for Cyril W. Foster (fl. 1933) who collected in the Krugersdorp area, South Africa, commemorated with Aloe fosteri. There is also an Arctotis fosteri, published by British botanist Nicholas Edward Brown in 1921, but I don't know yet who that commemorates. (Etymological Dictionary of Succulent Plant Names)

fouchei: possibly for a D. Fouche, listed as a plant collector in South Africa. Taxa in southern Africa with this specific epithet are Haworthia fouchei, published in 1940 by German botanist Karl von Poellnitz, and the former taxon Eriochloa fouchei, now synonymized to E. fatmensis. JSTOR records show a D.J. Fouche and an A.J. Fouche having collected the latter taxon on the same day, so they are certainly the same person and one of the records was probably misspelled.

fourcadei: for Henri Georges (Henry George) Fourcade (1865-1948), French-born South African forester, land surveyor, prolific plant collector, inventor, and botanist, recognised in 1927 by the Royal Society of South Africa for his work as a mathematician, surveyor, and botanist, received honorary doctorate from the University of Cape Town. He named a tremendous number of species, and was honored by specific epithets in the genera Erica, Drosanthemum, Trichodiadema, Ruschia, Phylica, Helichrysum, Gnidia, Struthiola, Watsonia, Oxalis, Sebaea, Restio, Aspalathus, Selago, Babiana, Gladiolus, Geissorhiza and others. He was a pioneer in the remote sensing and measuring technology called photogrammetry, a member of the Royal Society of South Africa, and his name is also on Mt. Fourcade in Antarctica. (JSTOR; Etymological Dictionary of Succulent Plant Names; Gunn & Codd)

fourei/fouriei: for Stephanus Petrus Fourie (1949- ), South African conservationist and plant collector, appoint-
ed to the Transvaal Division of Nature Conservation in 1975, head of the section for Flora and Nature Conser-
vation. He is commemorated with Aloe fouriei and Asparagus fourei. ("Additional Biographical Notes" by Gunn & Codd)

framesii: for Percival Ross Frames (1863-1947), a prolific plant collector in South Africa and Zimbabwe, solicitor, and grower of succulents, Director of Premier Diamond Co., member of the Rhodesian Legislative Council, commemorated with specific epithets in the genera Ixia, Aloe, Quaqua, Piaranthus, Lachenalia, Malephora, Lampranthus, Psilocaulon, Aridaria, Argyroderma, Delosperma, Ruschia, Drosanthemum, Cephalophyllum, Glottiphyllum and others. Vol. 4 of Flowering Plants of South Africa is dedicated to him. His name is sometimes hyphenated as Ross-Frames. (Etymological Dictionary of Succulent Plant Names; Gunn & Codd)

francescae: for Françoise Marie-Lise Williamson (née Clerc) (fl. 1956-2006), Swiss teacher and plant collector in Namibia and South Africa, wife of dental surgeon, botanist, succulent plant collector and author of Orchids of South Central Africa Dr. Graham Williamson, commemorated with Bulbine francescae and Euphorbia francescae. (Etymological Dictionary of Succulent Plant Names; Women and Cacti)

francesiae: for Miss Frances Margaret Leighton (later Mrs. William Edwyn Isaac) (1909-2006), South African botanist at the Bolus Herbarium 1931-1947, commemorated with Lampranthus francesiae. (Etymological Dictionary of Succulent Plant Names; Women and Cacti)

franchetianum/franchetii: for Adrien René Franchet (1834-1900), French botanist at the Paris Muséum National d'Histoire Naturelle, did extensive work describing the flora of China and Japan, commemorated with Cotoneaster franchetii and the former taxon Pennisetum franchetianum, now P. macrourum. (Etymolo-
gical Dictionary of Grasses)

francisci/franciscii: for (1) Franz de Laet (1866-1928), Belgian succulent plant expert and horticulturist, commemorated with Lithops francisci (Etymological Dictionary of Succulent Plant Names). (2) Frank J. Stayner (1907-1981), horticulturist and curator of the Karoo Botanic Gardens, honored with Lampranthus franciscii and Cephalophyllumfranciscii (Etymological Dictionary of Succulent Plant Names). (3) Frank Bolus (1870-1945), youngest son of Harry Bolus and husband of Mrs. H.M.L. Bolus (née Kensit) (Berkheya, Gnidia). I didn't record where this latter piece of information (#3) came from, and I can't confirm that it is correct. There is a JSTOR specimen record of Berkheya francisci being collected by H. Bolus and one for Gnidia francisci in Transactions of the South Africa Philosophical Society Vol. 16 collected by H. Bolus.

francoiseae: for Françoise Marie-Lise Williamson (née Clerc) (fl. 1956-2006), Swiss teacher and plant collector in Namibia and South Africa, wife of dental surgeon, botanist, succulent plant collector and author of Orchids of South Central Africa Dr. Graham Williamson, commemorated with Conophytum francoiseae. (Etymological Dictionary of Succulent Plant Names; Women and Cacti)

Frankenia: for Johan Frankenius (1590-1661), sometimes written as Franke or Franckenius or Franck, professor of anatomy, medicine and botany at Uppsala, Sweden, and the first writer on Swedish plants, author of Speculum botanicum, and a colleague of Swedish botanist Carl Linnaeus. The genus was published by Linnaeus in 1753. (CRC World Dictionary of Plant Names)

franksae/franksiae: for Millicent Franks (1886-1961) (later Mrs. Flanders) , botanical artist, assistant to John Medley Wood at the Natal Herbarium, illustrated many species in Wood's Natal Plants, commemorated with Brachystelma franksiae, Euphorbia franksiae, Phacelurus franksiae, Sisyranthus franksiae and the former Celtis franksiae, now synonymized to C.mildbraedii. (Etymological Dictionary of Succulent Plant Names)

frappieri: probably for someone named Frappier, with no further information. The taxon in southern Africa that has this specific epithet is the former Lophocolea frappieri, published in 1907 by German bryologist Franz Stephani, now synonymized to L. fragrans.

fraseri: for George Hobart Bedford Fraser (1870-?) (fl. 1920), appointed to the Cape Department of Forestry in 1901, stationed in the Transkei and Pondoland, commemorated with the former taxon Pseudoscolopia fraseri, now synonymized to P. polyantha, and also Rhus fraseri. The JSTOR website lists a specimen of Rhus fraseri collected by a Mr. Fraser in South Africa in 1925. (Gunn & Codd; JSTOR)

fredericii: for Frederick Huntly Holland (1873-1955), South African businessman and naturalist, commemor-
ated with Delosperma fredericii. (Etymological Dictionary of Succulent Plant Names). The same derivation may or may not apply to Gladiolus fredericii (see next entry) and Ruschia fredericii. Another unconfirmed source says that the specific epithet fredericii could alternatively refer to Frederick Adolf Wislizenus (1810-1889), Army surgeon, explorer, botanist and plant collector of German birth who travelled extensively in the southwestern United States.

frederickii: for Frederick W. Duckitt, South African plant collector from the Darling area of the western Cape, commemorated with Ixia frederickii, published in 1988 by Miriam Phoebe de Vos. There is a former taxon with this specific name, Gladiolus frederickii or fredericii, published by Harriet Margaret Louisa Bolus, and now synonymized to G. wilsonii, and about which there seems to be some confusion regarding the name. It was originally published as fredericii and that is the name that is recognized by Tropicos at Missouri Botanic Garden and by the Plant List maintained by Kew Gardens, however the International Plant Names Index and the Plants of Southern Africa database record it as Gladiolus frederickii inasmuch as it apparently commemorates the South African botanist and missionary Frederick Arundel Rogers (1876-1944), Archdeacon of Pietersberg in the Transvaal. The name fredericii as published by Louisa Bolus was presumably a Latinization of a personal name and according to section 60.7 of the current International Code of Botanical Nomenclature: "When changes in spelling by authors who adopt personal, geographic, or vernacular names in nomenclature are intentional latinizations, they are to be preserved, except when they concern (b) changes to personal names involving (1) omission of a final vowel or final consonant." Taking the name Frederick and changing it to fred-
ericii involves omission of the final consonant, and thus it would seem that the epithet fredericii need not be preserved. Interestingly, Louisa Bolus also published the name Ruschia fredericii, but I don't know who that name commemorates. (Clare Archer, SANBI, pers. comm.)

Freesia : for Friedrich Heinrich Theodor Freese (1795-1876), a German physician and botanist from Kiel and a pupil of Ecklon who like his teacher studied South African plants. The genus was published in 1866 by German botanist Friedrich Wilhelm Klatt. (PlantzAfrica; CRC World Dictionary of Plant Names)

Fresenia: for Johann Baptist Georg Wolfgang Fresenius (1808 – 1866), German physician and botanist; studied medicine at Universities of Heidelberg, Würzbug and Giessen, curator of the Senckenberg herbarium and a teacher at the Senckenberg Research Institute. His special interest was phychology (study of algae). The plant genus Fresenia from the family Asteraceae was named after him in 1836 by Swiss botanist Augustin Pyramus de Candolle.

Freylinia: for Count Lorenzo de Freylino/Freilino (1754-1820). The Count owned a famous private botanical garden in Buttigliera d'Asti, about 15 miles east of Turin and about 45 miles SE of Marengo in Italy in the early 19th century. The genus Freylinia was published in 1823 by Italian lawyer and botanist Luigi (Aloysius) Colla. He was also honored with the genus Freyliniopsis, published in 1922 by German botanist Heinrich Gustav Adolf Engler. There are eleven species of Freylinia in southern Africa, eight of which are in the Cape Province. (PlantzAfrica; CRC World Dictionary of Plant Names; Lotte Burkhardt, pers. comm.)

friderici-guilielmi: for Friedrich Wilhelm III, King of Prussia (1770-1840), who was a patron of botany, commemorated with Encephalartos friderici-guilielmi.

fridericii: for Friedrich Martin Joseph Welwitsch (1806-1872), Austrian botanist, explorer and medical doctor, Director of Lisbon Botanic Garden, author of Fungi Angolenses, commemorated with Eulophia fridericii.

friedrichiae: for Margarete (Margarethe) Friedrich (fl. 1914), South African teacher and mesemb collector who often accompanied Kurt Dinter, commemorated with Euphorbia friedrichiae and Conophytum friedrichiae. (Etymological Dictionary of Succulent Plant Names; Women and Cacti)

Friedrichsthalia: for Emmanuel Ritter von Friedrichsthal (1809-1842), Czech born explorer, botanist, archae-
ologist and daguerreotypist who undertook several scientific journeys for the Austrian Government. While travelling he became ill, probably malaria, and returned to Vienna where he died. The genus was published in 1839 by Austrian botanist Eduard Fenzl. (CRC World Dictionary of Plant Names)

friesii: for (1) Thore Christian Elias Fries (1886-1930), Swedish botanist who collected it in Zimbabwe in 1930. He was a specialist in lichenology and plant geography, and brother to noted botanist and mushroom expert Robert Elias Fries. He was professor of systematic botany at Lund University, travelled and collected in Africa and India and died during a field trip to South Africa and Rhodesia. He is commemorated with Era-
