    HI-HY


       In the following names, the stressed vowel is the one preceding the stress mark. It is not always easy to ascertain where such stress should be placed, especially in the case of epithets derived from personal names. I have tried to follow the principle of maintaining the stress of the original name as outlined in the Jepson Manual, and have abandoned it only when it was just too awkward. In the case of some names, I have listed them twice, reflecting either some disagreement or conflict in the rules of pronunciation, some uncertainty on my part as to the correct pronunciation, or that simply sometimes there is no single correct pronunciation. In other instances, the way I record it is just that which sounds right to my ear.

  • hi'ans: gaping (ref. Chenopodium hians)
  • Hibis'cus: the ancient Greek and Latin name for some mallow-like plant (ref. genus Hibiscus)
  • hick'manii/hickman'ii: after John Bale Hickman (1848-1929). From Cantelow and Cantelow, "Biographical Notes on Persons in whose Honor Alice Eastwood Named Native Plants," (Leaflets of Western Botany 8 (5): 83-101): "Teacher, horticulturist; born in Oxford, England, 1848, died at Watsonville [actually at Aromas] California, 4 Feb 1929. He taught school at Carneros Canyon on the Natividad road in the San Miguel Hills in Monterey County, California, and spent his spare time and vacations searching that area and the Monterey Bay area for interesting plants; sent some to Prof. Greene, University of California, Berkeley, and some to the California Academy of Sciences." And David Hollombe adds: "He was also horticultural commissioner for Monterey County 'for years.' He came to the U.S. as an infant, lived in Marshall, Michigan and Buffalo, New York before coming to California probably about 1868. He married twice and had two daughters." (ref.

  • hitchcockia'na: after Smithsonian Institution agrostologist and botanical illustrator Albert Spear Hitchcock (1865-1935), author of Manual of the Grasses of the United States, Manual of the Grasses of the West Indies, and North American Species of Agrostis. The following is quoted from a website of the Hunt Institute for Botanical Documentation:  "Botanical explorer and systematic agrostologist Albert Spear Hitchcock was born in Owosso, Michigan, on 4 September 1865, grew up in Kansas and Nebraska, and attended Iowa Agricultural College (later Iowa State College and now Iowa State University of Science and Technology) in Ames. Although he had long been interested in plants and studied botany under professor Charles E. Bessey, he earned a B.S. in agriculture and graduate degrees in chemistry and went on to teach chemistry at Iowa State from 1886 to 1889. When he could no longer resist the lure of botany as a full-time occupation, he accepted positions as librarian and curator of the herbarium at the Missouri Botanical Garden and also taught in the Engelmann School of Botany, Washington University.
        In 1890, he married Rania Belle Dailey, with whom he had five children. He moved to Kansas State Agricultural College in Manhattan, where from 1892 to 1901 he was a professor of botany and botanist to the Experiment Station. During this period he began to travel extensively, seeking types of grasses for his research on the world's grass genera. Hitchcock's colleague Mary Agnes Chase knew well Hitchcock's dedication to his science, recounting how he had once walked 242 miles in 24 consecutive days and camped at night, all the while toting a special wheelbarrow he had designed especially for botanizing. On the subject of his fieldwork in the salt marshes of the Gulf Coast, Hitchcock remarked: "I waded through water almost up to my knees, pushed my wheelbarrow, and still managed to keep my collection dry. The mosquitoes were very bad. I had to put on my coat, put cheesecloth around my head and a pair of extra socks on my hands. My shoes had worn through and my feet were blistered.... But, for all the discomforts, the collecting was magnificent, and I felt fully repaid." The fruits of this period's botanical labors were over 80 papers, including papers on grasses and the flora of Kansas, and Experiment Station bulletins and circulars.
        In 1901 Hitchcock became assistant chief in the U.S.D.A.'s Division of Agrostology in Washington, D.C., and in 1905 he was promoted to systematic agrostologist at the U.S.D.A. and also appointed custodian of the newly established Section of Grasses; Chase assumed the custodianship of the grass herbarium at Hitchcock's death (see also: Morton, C. V. and W. L. Stern. 1966. The United States National Herbarium. Pl. Sci. Bull. 12(2): 1–8). U.S.D.A. made the grass collection a priority, and Hitchcock built upon the work of his predecessors George Vasey and Frederick Lamson-Scribner. Determined to build the grass collection and "insatiably eager to see every part of the earth" (Chase, 1936, eulogy), Hitchcock visited every state in the U.S., as well as the West Indies, Cuba, Alaska, Canada, Mexico, the Philippines, Japan, and China, and traveled throughout Africa, Indochina, Central and South America as well. In 1928 he was promoted to principal botanist in charge of systematic agrostology in the U.S.D.A.
        From 1905 on, he filled 45 field books with notes, and for nearly 40 years, beginning with an account of the grasses of Kansas (1896–1898), published extensively on Gramineae, authoring over 250 works, several jointly with Chase. His publications include A Text-Book of Grasses (1914), The Genera of the Grasses of the United States (1920), Methods of Descriptive Systematic Botany (1925), Manual of the Grasses of the United States (1935), and Manual of the Grasses of the West Indies (1936), and monographs of the American species of Agrostis, Leptochloa, Panicum (with Chase), and Aristida.
        Hitchcock died of heart failure on 16 December 1935, at sea on board the steamer "City of Norfolk" while returning home with his wife from Europe, where he had attended the Sixth International Botanical Congress in Amsterdam, visited many European herbaria in preparation for a work on the grass genera of the world, and celebrated his 70th birthday. Hitchcock was held in high esteem by his peers and colleagues: "[H]e was a lovable and unassuming man. To the student of systematic botany who knew only his work, he was a tireless and productive student of a technically difficult and to many botanists quite uninteresting group of plants, the grasses. His contribution to our understanding of this economically most important family of plants has been unequalled in America" (Fernald, M. L. 1937. Proc. Amer. Acad. Arts Sci. 71(10): 505–506). Enriched by the hundreds of thousands of specimens acquired by Hitchcock and Chase throughout their collaborative careers, the Smithsonsian Institution's grass herbarium became the largest and one of the most complete such grass collections in the world. Hitchcock and Chase also bequeathed to the Smithsonian in 1928 their private agrostological library; among its 6,000 books and pamphlets were Linnaean titles, early systematic works, and rare books on the grasses." (ref. Festuca hitchcockiana)
  • hitchcockia'nus/hitch'cockii/hitchcock'ii: after Charles Leo Hitchcock (1902-1986), who published a monograph on North American Lathyrus in 1952, and was also the author of Flora of the Pacific Northwest: An Illustrated Manual, and with others the 5-volume Vascular Plants of the Pacific Northwest (ref. Lathyrus hitchcockianus, Sisyrinchium hitchcockii)
  • hoff'mannii/hoffmann'ii: named for Ralph Hoffmann (1870-1932), graduate of Harvard, an ornithologist (author of two books on ornithology) and botanist (author of A Flora of Berkshire County, Massachusetts in 1922), and Director of the Santa Barbara Museum of Natural History, who died after falling from a cliff while collecting on San Miguel Island. He did a great deal of his work on the Channel Islands, in the Santa Barbara region, in the higher San Rafael Mountains, and in the desert areas of Southern California (ref. Arabis hoffmannii, Cryptantha hoffmannii, Eriogonum hoffmannii, Gilia tenuiflora ssp. hoffmannii, Sanicula hoffmannii)
  • Hoffmannseg'gia: after Johann Centurius, Count Von Hoffmannsegg (1766-1849), a German botanist and co-author of a flora of Portugal (ref. genus Hoffmannseggia)
  • Hoi'ta: my friend David Hollombe sent along the following: "Hoita, with short i, long a and accent on the middle syllable, was recorded by Victor King Chesnut (1867-1938) as a name for "Psoralea" in the ConCow (or KonKow) Maidu language spoken by a Native American people of the Feather River region (Butte County, California) who were relocated to a reservation in the Mendocino area." The KonKow Valley is about 20 miles north of present day Oroville, California. A reference is Victor K. Chesnut, "Plants used by the Indians of Mendocino County, Calif.", Contributions from the U. S. National Herbarium, 1902. Another website with some interesting history and cultural information about the Maidu tribe is www.maidu.com. So it appears that the correct pronunciation of this name, rather than "hoy-ta," should be "ho-I-tay" with the middle syllable accented. Victor K. Chesnut was also co-author of "Ilex vomitoria as a Native Source of Caffeine," in the Journal of the American Chemical Society 41: 1307-1313, 1919. A collection of the papers relating to his interest in Yellowstone National Park history and containing an original transcript of the diary from the Folsom-Cook Expedition (a privately funded expedition in 1869 and the first of six into what would later become Yellowstone National Park) is in the Renne Library at Montana State University. A website of MSU includes the following biographical information: "Victor King Chesnut was born in Nevada City, California on June 28, 1867. He attended high school in Oakland, California and college at the University of California, the University of Chicago, and George Washington University specializing in chemistry and botany. He worked for the Bureau of Plant Industry, U.S. Department of Agriculture from 1894-1904, and as a professor of chemistry and geology at Montana Agricultural College (Montana State University) from 1904-1907. Following his work in Montana, Chesnut relocated to Washington, DC where he finished his career working in a variety of positions for the USDA. He retired in 1933 and died in August, 1938. Letters, diary transcripts and research notes pertaining to the 1869 Cook-Folsom expedition into Yellowstone National Park were gathered or created by Chesnut during his employment at Bozeman Montana (1904-1907) and Washington, D.C. (1921-1922). In 1904, Chesnut met Charles W. Cook, an elderly farmer living in White Sulphur Springs, Montana. Cook, along with David E. Folsom and William Peterson, had explored the Yellowstone National Park region in 1869 and recorded their journey in a joint "diary" which had appeared in edited form several times during the intervening years. Cook gave Chesnut his original manuscript version of the diary from which Chesnut prepared a typed transcript." The original was lost when he left it in the Chemistry Building at Montana Agricultural College which burned Oct. 20, 1916, thus Chesnut's transcription became the earliest extant record of the expedition. Chesnut was one of a group of scientists that were assigned by the US Department of Agriculture to investigate livestock losses as a result of poisonous plants, and in 1898 he published a list of 30 such species in and on Western grazing lands. A website of the University of Maryland indicates that Dr. Chesnut (misspelled Chestnut) in 1916-1917 was one of the founders and the first president of the Hyattsville Horticultural Society, one of the oldest gardening clubs in America. The taxon Ribes victoris is also named for him (ref. genus Hoita)
  • hol'boellii/holboell'ii: the taxon Arabis holboellii was named from Greenland in 1828 by Jens Wilken Hornemann, a professor of botany at Copenhagen after the eminent Danish ornithologist Carl Peter Holboell (1795-1856). Actually, in Danish his name is spelled without an 'e', the second 'o' being one of those with a slash through it, one of the extra vowels in the Danish alphabet that has a sound close to 'bird' or 'heard' and often transcribed in English as 'oe.' He was a Royal Navy lieutenant in 1821, travelled in Greenland in 1822, and became Royal Inspector of Colonies and Whaling in 1825, a position he held in North Greenland until 1828 and then in South Greenland until his death in 1856. He also authored a book about the birds of Greenland, and his interest in natural history led him to name and describe several species of birds, and have several named after him. His father was Frederik Ludvig Holboell, also a botanist and Curator of the Botanic Garden in Copenhagen (ref. Arabis holboellii)
  • holcifor'mis: like Holcus, a Greek name for a type of grain (ref. Deschampsia cespitosa ssp. holciformis)
  • Hol'cus: from the Greek holkos, an ancient name for some kind of grain or possibly grass (ref. genus Holcus)
  • Hollister'ia: after (Col.) William Welles Hollister (1818-1886), California rancher and entrepreneur. He came to California from Ohio in 1853-1854 as the leader of a 2000-mile-long sheep drive accompanied by his brother Joseph Hubbard Hollister, their sister Lucy Brown and 50 herdsmen. His idea was that the miners of the gold rush needed plentiful meat. Although only about a thousand sheep survived, he was able to make a considerable fortune out of it and purchased a large amount of land that would one day bear his name. He was a founder of the town of Hollister in San Benito County, (“Because so many California towns are named for saints,” said one of the town organizers of Hollister in San Benito county, “let’s name this one for a sinner.”), remaining for some 14 years before selling his part of the Rancho San Justo and moving his sheep south to Santa Barbara. He married Ann (Hannah) James in 1862. During the 1870s, William Hollister made many contributions to the Santa Barbara area including helping to finance or develop Santa Barbara College, the Arlington Hotel, the local newspaper, Steams Wharf, and the Lobero Theater. He was also an avid horticulturist. In 1875 he built a wharf at Gaviota to ship lumber, wool, cattle and grain back to markets on the Atlantic coast. The following is quoted from an online article called "A Man Named Hollister" by Alton Pryor: "Money was of little consequence to the now-wealthy Hollister. He built more than six miles of fencing, virtually unheard of in Santa Barbara County. He established a dairy herd and imported a landscape gardener to plant velvety lawns and exotic flora around the property. He widened the county road, now Hollister Avenue, linking Santa Barbara and Goleta, and bordered it with an avenue of palms and pines. Always adventurous, Hollister imported 25 bushels of Japanese tea plants, which he thought would grow in the soil and climate of his Dos Pueblos Rancho. He hired two Japanese tea planters to plant his 50,000 seedlings. A frost killed the entire tea project overnight. The Refugio Rancho is probably the first working cattle ranch apart from mission operation in Santa Barbara County. In the 1860s, Chinese workers were brought to Santa Barbara County from Canton by Colonel W. W. Hollister to work on his Goleta Valley estate and to serve as bus boys, chefs, and waiters in his hotel. Between 1869 and 1877, W.W. Hollister planted 25,000 almond trees, 1,500 English walnuts, 1,500 orange trees, 1,000 lemons, 500 limes, and 750 olives. Col. Hollister’s land grants included Lompoc. Here, vast herds of his sheep grazed before he sold part of his holdings to the Lompoc Valley Land Company in 1874. The lands consisted of the Lompoc Rancho and the Mission Vieja de la Purisima Rancho. The town was laid out nine miles from the coast, near the center of the Lompoc Valley." His son was rancher and California state senator John James Hollister, Sr. (ref. genus Hollisteria)
  • Holmgrenan'the: named for Arthur Herman Holmgren (1912-1992), a professor At Utah State University in Logan, expert on grasses, and co-author of the Intermountain Flora, Noel Herman Holmgren (1937- ), his son, plant collector, and Patricia Kern Holmgren (1940- ), Herbarium Director at the New York Botanical Garden, worked on the the five-volume Vascular Plants of the Pacific Northwest, and helped edit the first volume of Intermountain Flora published in 1972 (ref. genus Holmgrenanthe)
  • holmgrenan'us: see previous entry (ref. Lupinus holmgrenanus)
  • holocar'pa: with unlobed fruit
  • holo-: in compound words signifying "completely"
  • Holocar'pha: from the Greek holos, "whole," and karphos, "chaff," referring to the entirely chaffy receptacle (ref. genus Holocarpha)
  • Holodis'cus: from the Greek holos, "entire," and diskos, "a disk," the disk unlobed (ref. genus Holodiscus)
  • hololeu'ca/hololeu'cus: wholly white (ref. Castilleja hololeuca, Ericameria [formerly Chrysothamnus] nauseosa var. hololeuca, Lessingia hololeuca)
  • holopet'ala: whole-petalled (ref. Gentianopsis [formerly Gentiana] holopetala)
  • holop'tera: from the prefix holo-, "complete or completely," and pteron, "wing" (ref. Cryptantha holoptera)
  • holorho'dos: from holo-, in compound words meaning "completely," and rhodo, "red"
  • holoseri'cea: woolly-silky (ref. Urtica dioica ssp. holosericea)
  • holosteo'ides: like genus Holosteum (ref. Drymaria holosteoides)
  • Holos'teum: from the Greek holosteon, "entire bone," an ancient Greek and Latin plant name used by Dioscorides and Pliny for a whitish plantain species, and derived in turn from holos, "whole, all," and osteon, "bone" (ref. genus Holosteum)
  • Holozon'ia: from holos, "whole, entire," and zone or zona, "a belt or girdle," hence "whole-girdled" (ref. genus Holozonia)
  • hood'ii: after Robert Hood (1797?-1921). The following is quoted from the website of the Arctic Institute of North America: "Robert Hood was a junior officer with the badly timed, inadequately supplied first Arctic Land Expedition led by John Franklin in 1819-1822. Hood made a major contribution to the expedition's incredibly accurate mapping of over 600 miles of coastline, which, in the words of L.H. Neatby, 'put a roof on the map of Canada.' Hood was the first to prove the action of the aurora borealis on the compass needle and to show that the aurora was an electrical phenomenon. He also made important contributions to our knowledge of terrestrial magnetism, climatology, anthropology, and natural history. Hood's journal, a less formal and more sprightly account of the journey than Franklin's, was published with many of his watercolour paintings 153 years after his tragic death on the Barrenlands. ... Hood contributed in full measure to the success of the first expedition before he paid the supreme sacrifice - and his journals and paintings remain one of the earliest and most vivid records of life in the Canadian North. Although his promising career was terminated prematurely, his memory is perpetuated by a flower, the moss phlox, Phlox hoodii, a sedge, Carex hoodii, the thirteen-striped squirrel, Citellus tridecemlineatus hoodii, and by the mighty Hood River that plunges over Wilberforce Falls before entering the Arctic Ocean." His manuscript, "Narrative of the Proceedings of an Expedition of Discovery in North America under the Command of Lieut. Franklin, R.N.," was published as To the Arctic by Cabnoe, 1819-1821: the Journal and Paintings of Robert Hood, midshipmen with Franklin, edited by C.S. Houston and published in 1974. Hood's paintings of birds and other wildlife were exceptional for the time, and at least five of the birds he painted were unknown to science. Had they been published at the time of their arrival in London, and the birds named, he would have received the credit for priority in their discovery. His journals described the flora and fauna of the regions they travelled through, and included information on geography and the transportation, fishing and hunting techniques of the native peoples they encountered (ref. Carex hoodii, Phlox hoodii)
  • hook'eri: after Sir Joseph Dalton Hooker (1817-1911), botanist and plant collector, biogeographer, and younger son of William Jackson Hooker. He succeeded his father as Director of Kew Gardens in 1865, a position he held until he retired in 1885 due to ill health. He travelled the world on botanical quests and became a friend of Charles Darwin and John Muir. He participated in the Antarctic expedition of the HMS Erebus (1839-1843) as naturalist and assistant surgeon. His two-volume Flora Antarctica (published 1844-1847), Flora Novae-Zelandiae (1851-1853), and Flora Tasmanica (1853-1859) were based on the specimens collected during the Erebus expedition. He suspected an ancient connection between the landmasses of Africa and South America, an idea later confirmed by the concept of continental drift. Between 1847 and 1850 he explored the Indian subcontinent including Nepal, work which later resulted in his seven-volume Flora Indica. He also produced with George Bentham a major work entitled Genera Plantarum which was a world flora including the descriptions of some 7,569 genera and 97,000 species! In 1859 he published his Introductory Essay to the Flora of Australia. He visited Syria in 1860 and Morocco in 1871, and travelled to Colorado and Utah in the United States in 1877. He also served as President of the Royal Society from 1873 to 1877 (ref. Eriogonum hookeri)
  • hook'eri: named for Sir William Jackson Hooker (1785-1865), professor of botany and director of the Royal Botanical Gardens at Kew in the mid 19th century and author of several botanical works.  Some of his friends and colleagues were the Scot David Douglas, the Englishman Thomas Nuttall, Sir Joseph Banks, and the American Asa Gray, after whom he named the genus Grayia.  It was under his directorship that Kew became a world center for plant study. His first botanical expedition was to Iceland at the behest of Joseph Banks, but unfortunately his notes, drawings and collected specimens were lost when his ship burned on the return journey. He was largely responsible for botanists being appointed to government expeditions and his herbarium received large collections from all over the world. Published works of his included the Muscologia (1818) on the mosses of Britain and Ireland, Musci exotici (1818-1820, two volumes) on foreign mosses and other cryptogamic plants, and Flora Scotica (1821) (ref. Arctostaphylos hookeri, Balsamorhiza hookeri, Oenothera elata ssp. hookeri, Silene hookeri)
  • hookeria'na/hookeria'num: see previous entry (ref. Salix hookeriana, Hypericum hookerianum)
  • hoopes'ii: after Thomas Hoopes (1834-1925), entrepreur in West Chester, PA., who with his brother William established a wheel works which produced wheels for carriages and wagons for 100 years. He was related to the well-known horticulturist Josiah Hoopes. At the end of the 1850's he was exploring in the Rocky Mountains area of Colorado and collected a species previously unknown that was named by Asa Gray Helenium hoopesii and which subsequently became Dugaldia hoopesii, and is now included in Hymenoxys (ref. Hymenoxys [formerly Dugaldia] hoopesii)
  • hoo'veri: after Robert Francis Hoover (1913-1970), an American botanist who collected in California and whose wife was Bettina Louise Brown. A subtaxon of Dudleya abramsii ssp. bettinae, was named by Hoover for her (ref. Agrostis hooveri, Arctostaphylos hooveri)

He was a lecturer at the Copenhagen Botanical Garden and professor of botany at the University of Copenhagen, also the editor of Flora Danica from 1805 until his death. He travelled extensively in Germany, France, England, Denmark and Norway. The taxon Arabis holboellii was first described by Hornemann and named in honor of the eminent Danish ornithologist Carl Peter Holboell (ref. Epilobium hornemannii)
  • horn'ii: after Dr. George Henry Horn (1840-1897), born in Baltimore, received a medical degree from the University of Pennsylvania, was commissioned as a cavalry surgeon and served in California for three years, during which time he studied and collected insects, which was one of his primary interests. After moving back east he was elected President of the Entomological Society of Philadelphia, and in addition to a successful career in obstetrics, published 265 scientific papers, establishing 154 new genera and 1,582 new species of beetles. He became an authority especially on scarab beetles, and his collection and library is at the Academy of Natural Sciences in Philadelphia. While in California, he collected plants at Fort Tejon and Fort Independence in Inyo County on behalf of the eminent Asa Gray at Harvard (ref. Astragalus hornii)
  • Hor'nungia: after Ernst Gottfried Hornung (1795-1862), German pharmacist, botanist and entomologist (ref. genus Hornungia)

  • horten'sis: of or pertaining to gardens (ref. Atriplex hortensis)
  • hortor'um: same as above entry (ref. Pelargonium Xhortorum)
  • Hosack'ia: named for a Dr. David Hosack (1769-1835), noted physician, botanist and educator who was the originator of the first botanical garden in the United States, called Elgin Botanical Garden in New York, with1500 species of plants. He was the doctor who attended to Alexander Hamilton after his deadly duel with Aaron Burr. He had also attended to the son of Alexander Hamilton who was shot in a duel at the same location three years earlier. After returning from a period of time in England, first his son died, then his wife died in chidbirth. He was a professor of natural history, botany, and midwifery and surgery at Columbia College, the founder of the New York Horticultural Society, and was elected a foreign member of the Royal Swedish Academy of Sciences.

  • Howellia/howel'lii: after Thomas Howell and his brother Joseph (1830-1912) who preceded him in death by only two months (ref. genus Howellia, Isoetes howellii, Montia howellii)
  • howel'liana: see Howelliella/howellii below (ref. Cuscuta howelliana)
  • Howellanthus: named for John Thomas Howell (1903-1994), see next entry (ref. genus Howellanthus)
  • Howelliel'la/howel'lii: named in honor of John Thomas Howell (1903-1994), assistant to Alice Eastwood and her successor as Curator of Botany of the California Academy of Sciences.  He had become Assistant Curator in 1930 and was appointed as Curator the day after she retired in 1949 serving until January 1969 and being succeeded in turn by Dennis Eugene Breedlove. With Eastwood, he started a journal called Leaflets of Western Botany which was published from 1932 to 1968.  He was a scholar of the Eriogonums and was the author of Marin Flora: A Manual of the Flowering Plants and Ferns of Marin County, and a co-author of A Flora of Sonoma County with Catherine Best, Irja Knight and Mary Wells as well as A Flora of San Francisco, California with Peter Raven and Peter Rubtzoff.  He was also a principal mentor of Mary DeDecker.  "More than 50 years ago, [he] came upon wildflowers blooming in the charred 'remains' of a chaparral wildfire on the side of Mount Tamalpais.  He had never seen a display to match it.  'It's a wonder,' he wrote, 'that ecologists don't become arsonists in order to behold the beauty after burns.' " (from Bay Nature)  The following memorium is from a website of the Flora of North America Project: "Tom was born in Merced, California and by the time he entered high school there, he had become particularly interested in plants.  He studied botany under W. L. Jepson at the University of California at Berkeley and received his M.A. in 1927. From 1927-1929, Tom was the first resident botanist at the Rancho Santa Ana Botanic Garden when it was still located on Susanna Bixby Bryant's ranch in Santa Ana Canyon.  There, he founded the herbarium of the Rancho Santa Ana Botanical Garden (RSA).  In 1929, Alice Eastwood offered Tom a position in the herbarium at the California Academy of Sciences where he spent the next 65 years in botanical exploration, research, and public education.  Although Tom collected nearly 55,000 plants, mostly from throughout California and the western United States, tropical botanists recognize his enormous contributions to the study of the Galapagos Islands flora. From March to September of 1932, Tom was a botanist on the Templeton Crocker Expedition to the Galapagos where he collected 1,627 plants on 14 of the islands. These collections formed the basis for some of the first serious revisionary studies of plant groups with significant radiation in the Galapagos Islands.  Tom's publications on the Galapagos flora dealt with such groups as Mollugo, Cactaceae, Amaranthaceae, Tiquilia, Scalesia, and Polygala.  In California, Tom collected plants in the Sierra Nevada for some 25 years with the prospect of writing a flora of that mountain range.  The 20 herbarium cases housing specimens generated by those efforts are now being incorporated into the Academy's herbarium. Because they were largely unmounted, Howell's Sierran plants were not readily accessible for use by authors of the recent Jepson Manual.  Botanically, Tom was a generalist with a particular interest in regional floras.  Plants named for Tom include an alga, a fungus, a lichen, a liverwort, a moss, monocots, and dicots.  His "specialities" included the Asteraceae, Cyperaceae, Hydrophyllaceae, Poaceae, Polygonaceae, Rhamnaceae, and Rubiaceae.  His bibliography includes more than 500 entries, most of which deal with California plants.  He considered his editing and publication of the private journal Leaflets of Western Botany (10 volumes and index, 1932--1968) to be his most important contribution to California botany.  Another of Tom's best known and most popular publications is Marin Flora, Manual of the Flowering Plants and Ferns of Marin County, California.  Although Tom did not teach in a university classroom setting, he probably taught botany to nearly as many people as most college professors. His "students" included Junior Academy schoolchildren, Sierra Club chapters, the California Native Plant Society, and California Botanical Club.  Tom served as leader of this latter organization (which was founded in 1891 by Katherine Brandegee) from 1950 to 1970.  Over the years he was a mentor to a loyal following of amateur and professional botanists.  Tom's influence extended beyond informal botanical instruction and encouragement.  In many cases he nurtured dedication among his followers that led to important collaborative publications such as A Flora of San Francisco (1958), A Flora of Lassen Volcanic National Park, California (1961), The Vascular Plants of Monterey County, California (1964), and A Catalogue of Vascular Plants on Peavine Mountain (1992).  In the years preceding his death Tom was actively involved in a collaborative study of the flora of Sonoma County.  Tom was especially proud of having received the Willdenow Medal from the Berlin Botanical Garden and Museum (1979) and the Fellows Medal of the California Academy of Sciences (1986).  Following his retirement, the John Thomas Howell Curatorial Chair of Western American Botany was established at the Academy.  The endowment for this chair continues to grow and it will be activated when sufficient funds become available.  His many friends and colleagues will miss Tom's thoughtful counsel, ever present humor, and zest for the flora of his native state.  A biographical sketch of Tom Howell's eventful and productive life appeared in Fremontia 17(1):11-19. 1989."  (ref. genus Howelliella, also Allium howellii, Chorizanthe howellii, Puccinellia howellii)
  • howel'lii: after Thomas Jefferson Howell (1824-1912), a collector of the flora of Oregon and Washington.  Born in Missouri, he moved with his family at the age of eight to the Oregon territory where they settled on Sauvie Island on the Columbia River outside of Portland. He collected plants found near his home and established an impressive herbarium, sending many specimens to Harvard and Europe.  He discovered more than 50 species and ran what may have been the region's first native plant nursery.  He was the author of A Catalogue of the Known Plants (Phaenogamia and Pteridophyta) of Oregon, Washington, and Idaho which was published in 1887 and listed 2,152 species.  After this was accomplished, he undertook to describe all the species in his list and despite marginal literacy (he attended only a few months of school, being educated mostly by his doctor father) and lack of funds, he wrote, produced and printed his own Flora of Northwest America to fill a gap that he perceived to exist in the botanical documentation of his country.  "To defray publication expenses, he learned how to set type, composed the pages of his book himself at home, then carried them into town for individual printing.  He completed the manuscript for this, his Flora of Northwest America, in 1897, and it was not completely printed and issued until 1903.  It remained the most complete account of the flora of the Pacific Northwest for nearly fifty years."  ( From a biographical sketch of Howell here.)  Howell and his brother Joseph (1830-1912) both became ardent botanical collectors and came to the attention of Asa Gray when they sent him samples for identification.  The great Harvard scholar even named one species they discovered after them to honor their contribution, Howellia aquatilis.  Howell's opus eventually reached 800 pages and remains a major work of the region.  My information is that John Thomas Howell and Thomas Jefferson Howell were not related (ref. Lomatium howellii, Poa howellii, Thelypodium howellii)
  • hubb'yi: after Frank Winfield Hubby, Sr. (1841-1918). David Hollombe sent me the following biographical information for which I express my gratitude: "Frank W. Hubby, Ojai Valley, California. Born in Cleveland, Dec. 23, 1841. Educated Cleveland grammar and high schools and Kenyon College, graduating at latter with "philosophical" honor. Treasurer Jamestown & Franklin R. R. Co. and Gen. Accountant Mercer Iron & Coal Co., 1865-1866. Then engaged in manufacture of axes and edge tools as treasurer and manager of Powell Tool Co., from its founding till it was merged with the American Axe & Tool Co. Still retains interests in various manufacturing enterprises of Cleveland and elsewhere. Joined with "Squirrel Hunters" campaign in defense of the Capitol at Washington. Member of Alpha Delta Phi and Phi Beta Kappa fraternities, the Winon's Point Shooting Club and other clubs, and member of St. Paul's Episcopal Church. Republican for many years; now independent." [from Progressive Men of Northern Ohio]. "At the age of forty he retired from active business and became an active resident of the Ojai Valley, California. He organized the Ojai Improvement Company, which developed the Valley's resources, and also planned and erected, with his associate, Mr. Foster, the well-known Foothills Hotel at Ojai and laid out the tennis courts where annual tournaments have been held for many years. Mr. Hubby and associates were the builders of the big dam at Bear Valley in San Bernardino County." [from History of Hollywood, 1937]. "The Hubby Herbarium, assembled about 50 years ago by Frank W. Hubby and Nora Pettibone at Ojai, Ventura County, has been one of the notable accessions of recent months. This herbarium is important chiefly for specimens from Ojai Valley and supplements the fine recent collections from the region that have been given to the Academy by Henry M. Pollard. Among the most interesting specimens are some collected by Miss Alice Eastwood in the 1890's around San Francisco, CA., duplicates of specimens the Academy lost in the Great Fire of 1906. This outstanding gift to the Academy was made by the Ojai Branch of the Ventura County Library." [From the (California) "Academy Newsletter", Feb. 1949] (ref. Phacelia hubbyi)
  • hudsonia'num: of or from the area around Hudson Bay in Canada (Ribes hudsonianum)
  • Hul'sea: named after Dr. Gilbert White Hulse (1807-1883), U.S. Army surgeon and botanist. The genus name was given by John Torrey and Asa Gray (ref. genus Hulsea)
  • humboldtien'sis: of or from Humboldt County (ref. Castilleja ambigua ssp. humboldtiensis)
  • hum'boldtii/humboldt'ii:  named for Friedrich Wilhelm Heinrich Alexander, Baron von Humboldt (1769-1859), a German geographer who Charles Darwin described as "the greatest scientific traveller who ever lived." The following is from a website called Enchanted Learning: "Baron Alexander von Humboldt was a Prussian naturalist and explorer who explored much of Central and South America. Humboldt and his friend, the French medical doctor/botanist Aime-Jacques-Alexandre Goujoud Bonpland (1773-1858), explored the coast of Venezuela, the Amazon and Orinoco Rivers, and much of Peru, Ecuador, Colombia and Mexico (1799-1805). On their many expeditions, Humboldt and Bonpland collected plant, animal, and mineral specimens, studied electricity (including discovering the first animal that produced electricity, Electrophorus electricus, the electric eel), did extensive mapping of northern South America, climbed mountains (and set altitude records), observed astronomical phenomena, and performed many scientific observations. The scientist Carlos Montufar (who later became a revolutionary in Ecuador) acconpanied them on part of the trip. Humboldt discovered what is now called the Humboldt Current off the west coast of South America, while he was investigating why the interior of Peru was so dry. It is a cold ocean current that runs along much of the western coast of South America, and is also known as the Peru Current. Humboldt was the first European to witness native South Americans preparing curare arrow poison from a vine. He was also the first person to recognize the need to preserve the cinchona plant (its bark contains quinine, which is used to cure malaria, and it was terribly over-harvested at the time). Humboldt was the first person to make accurate drawings of Inca ruins in South America (he visited the ruins at Canar, Peru). Humboldt and Bonpland discovered and mapped the Casiquiare Canal, the only natural canal in the world that connects two major rivers (the Orinoco River and the Negro River, a tributary of the Amazon). Humboldt was also the first person to discover the importance of guano (the dried droppings from fish-eating birds); it is an excellent fertilizer. After their South American expeditions, Humboldt and Bonpland visited the USA and were guests of President Thomas Jefferson in Washington, D.C., for three months in 1804 (their visit happened just after Jefferson had sent Lewis and Clark to explore the western US). At the age of 60, Humboldt traveled to the Ural mountains in Siberia and to Central Asia to study the weather. He wrote extensively of his travels and discoveries. One of his books, A Personal Narrative, inspired a young Charles Darwin. His last work was his multi-volume book, Kosmos, which tried to unify all of science. Humboldt died at age 90 (leaving Kosmos unfinished), and is buried in Tegel, Germany. Many landmarks in the Americas, including a current [the Humboldt], a river, a mountain range, a reservoir, a salt marsh, parks, many counties and towns are named for Humboldt. On the moon, the Mare Humboldtianum (Humboldt's Sea) was named for Humboldt." Species named after him include the Humboldt penguin (Spheniscus humboldti), the Humboldt's lily (Lilium humboldtii), a South American Oak (Quercus humboldtii), an orchid (Phragmipedium humboldtii) and other plants. And from Wikipedia: "The childhood of Alexander von Humboldt was not a promising one as regards either health or intellect. His characteristic tastes, however, soon displayed themselves; and from his penchant for collecting and labelling plants, shells, and insects he received the playful title of "the little apothecary." The care of his education, on the unexpected death of his father in 1779, devolved upon his mother, who discharged the trust with constancy and judgment. Destined for a political career, he studied finance during six months at the University of Frankfort-on-the-Oder; and a year later, April 25, 1789, he matriculated at Göttingen, then eminent for the lectures of Christian Gottlob Heyne and Johann Friedrich Blumenbach. His vast and varied powers were by this time fully developed, and during a vacation in 1789, he made a scientific excursion up the Rhine, and produced the treatise, Mineralogische Beobachtungen über einige Basalte am Rhein (Brunswick, 1790). His passion for travel was confirmed by friendships formed at Göttingen with Georg Forster, Heyne's son-in-law, the distinguished companion of Captain James Cook's second voyage. Henceforth his studies and rare combination of personal talents became directed with extraordinary insight and perseverance to the purpose of preparing himself for a distinctive calling as a scientific explorer. With this view he studied commerce and foreign languages at Hamburg, geology at Freiberg under Abraham Gottlob Werner, anatomy at Jena under J. C. Loder, astronomy and the use of scientific instruments under Franz Xaver von Zach and Johann Gottfried Köhler. His researches into the vegetation of the mines of Freiberg led to the publication in 1793 of his Florae Fribergensis Specimen; and the results of a prolonged course of experiments on the phenomena of muscular irritability, then recently discovered by Luigi Galvani, were contained in his Versuche über die gereizte Muskel- und Nervenfaser (Berlin, 1797), enriched in the French translation with notes by Blumenbach. In the summer of 1790 he paid a short visit to England in company with [his friend Georg] Forster. In 1792 and 1797 he was in Vienna; in 1795 he made a geological and botanical tour through Switzerland and Italy. He had obtained in the meantime official employment: appointed assessor of mines at Berlin, February 29, 1792. Although this service to the state was regarded by him as only an apprenticeship to the service of science, he fulfilled its duties with such conspicuous ability that he not only rose rapidly to the highest post in his department, but was as well entrusted with several important diplomatic missions. The death of his mother, on the 19th of November 1796, set him free to follow the bent of his genius, and severing his official connections, he waited for an opportunity to fulfill his long-cherished dream of travel to distant lands."

  • humifu'sa: sprawling (ref. Gaultheria humifusa)
  • hu'mile/hu'milis: low-growing, humble (ref. Gayophytum humile, Cycladenia humilis var. venusta, Phacelia humilis)
  • humistra'tum/humistra'tus: low layer, in reference to an often low-growing habit (ref. Lotus humistratus, Plagiobothrys humistratus)
  • Hum'ulus: a Latin name of uncertain origin, although it may have descended from the Low German word humela for hop, which is the common name of this genus placed by Munz in the Moraceae or mulberry family, but moved by Jepson along with Cannabis into the new family Cannabaceae (ref. genus Humulus)
  • huntia'na: after Loren Edward Hunt (1870-1916). David Hollombe contributes the following from various sources: Hunt was born in Austin, Minnesota, and his family came to Santa Barbara in 1872. Hunt taught engineering at U.C. from 1893 to 1904 and was later Principal Assistant Engineer of San Francisco. He conceived the high-power fire protection that was installed in San Francisco following the disastrous fire of 1906. I don't have any details handy on his collecting in California, but Hunt went on a collecting trip to Alaska in 1899 with Setchell, Jepson and A. A. Lawson. He was also captain of the U.C. football team while a student there and also for a time in charge of the U.C. forestry experiment station (ref. Clarkia affinis ssp. huntiana)
  • Hut'chinsia/Hutchins'ia: after Ellen Hutchins (1785-1815), an Irish botanist and talented botanical artist. She was particularly interested in cryptogams and seashore plants of the Bantry Bay area where she lived. She also collected around Belfast and along the west coast of Ireland. Most of her collection is at Kew Gardens. She contributed to the Flora of Hibernica by James Townsend Mackay, Curator of the Botanic Garden at Trinity College. She suffered from tuberculosis and died in Cork at the age of 30 (ref. genus Hutchinsia)
  • hutchinsifo'lia: with leaves like genus Hutchinsia (ref. Aliciella hutchinsifolia)
  • hutchinson'iae: after Susan Wipfler/Whipple (Mrs. William Wilson Hutchinson) (1880-1970). Thanks to David Hollombe for the following: "Her name was originally Susan Wiffler, and the family name had originally been Wipfler when her grandparents and father came to the U.S. (She probably changed to Whipple during World War I, because of anti-German feelings in the U.S.) She and her husband were trained as osteopaths, but she never practiced and her husband later (1917) earned an M.D. degree and became an anesthesiologist. They came to Los Angeles from Detroit in 1912. Marcus Jones called her 'the best woman botanist in California.' She encouraged Joseph Ewan (see ewanii) to study botany and eventually gave her herbarium to the University of Colorado." (ref. Delphinium hutchinsoniae)
  • hyacinthin'a/hyacinthin'us: hyacinthine means "light violet to purplish-blue in color," which would fit the color at least of L. hyacinthinus. There are however other possible and more likely derivations. One is that these names derive from hyacinth and the Greek or Latin adjectival suffix -inus which indicates color, appearance or resemblance, thus meaning essentially "like a hyacinth." Another stems from the fact that the word "jacinto" in Spanish means "hyacinth," and according to John Robinson's book on the San Jacintos, the original Rancho San Jacinto, which was part of Mission San Luis Rey, was apparently named after a Silesian-born Dominican missionary, Saint Hyacinth, who was referred to as San Jacinto in Spanish, and perhaps the San Jacinto Mts were named similarly. The connection between "jacinto" and "hyacinth" is stronger in the case of the lupine because it does grow there, whereas the Triteleia does not (ref. Triteleia hyacinthina, Lupinus hyacinthinus)
  • hyalin'um: translucent or transparent (ref. Allium hyalinum)
  • hy'brida/hy'bridum/hy'bridus: mixed, hybrid (ref. Fuchsia hybrida, Papaver hybridum, Trifolium hybridum, Alternanthera hybridus, Senecio hybridus)
  • Hydril'la: possibly a diminutive of hydra, "a water serpent," deriving from the Greek hydor, "water," and relating to the aquatic environment (ref. genus Hydrilla)
  • hydrocharo'ides: resembling genus Hydrocharis, from the Greek hydor, "water," and charis, "delicacy, delight, grace, beauty" (ref. Ranunculus hydrocharoides)
  • Hydroco'tyle: from the Greek hydor, "water," and kotyle, "a small cup" (ref. genus Hydrocotyle)
  • hydrophilo'ides: the background of this name is as follows (and thanks to Bob Allen for providing it): In 1841, Thomas Nuttall described Senecio hydrophilus, a very water-loving species found according to the Jepson Manual in swamps, muddy places, and tolerant of standing saltwater. In 1900, Per Axel Rydberg described Senecio hydrophiloides, a very similar water-loving species but one which is a little less water-loving than S. hydrophilus, and so he gave it the name which means "looks like [Senecio] hydrophilus (ref. Senecio hydrophiloides)
  • hydrophi'lum: water-loving (ref. Trifolium depauperatum var. hydrophilum)
  • Hydrophyl'lum: from the Greek hydor, "water," and phyllon, "a leaf" (ref. genus Hydrophyllum)
  • hydropi'per: from the Latin prefix hydro- for "water" and piper, "pepper," this taxon is commonly referred to as waterpepper or marshpepper (ref. Polygonum hydropiper)
  • hydropipero'ides: having a resemblance to hydropiper (ref. Polygonum hydropiperoides)
  • hyema'le: of the winter, flowering in winter (ref. Equisetum hyemale ssp. affine)
  • hymenely'tra: from the Greek hymen, "membrane," and elytra, "a sheath or cover" (ref. Atriplex hymenelytra)
  • Hymeno'clea: from the Greek hymen, "membrane," and kleio, "to enclose" (ref. genus Hymenoclea)
  • hymeno'ides: the -oides suffix denotes likeness of form or resemblance to, and so this apparently means something like, "resembling a membrane," of uncertain application (ref. Achnatherum hymenoides)
  • Hymenon'yx: from the Greek hymen, "membrane," and onyx, "nail, talon, claw" because of the pointed tips of the pappus scales (ref. genus Hymenonyx)
  • Hymenopap'pus: from the Greek hymen, "membrane," and pappos, "pappus," because of the hyaline (colorless or translucent) paleae, which are the chafflike scales on many species of Asteraceae (ref. genus Hymenopappus)
  • hymenosep'alus: in Latin means "having membranous sepals" (ref. Rumex hymenosepalus)
  • Hymeno'thrix: from the Greek hymen, "membrane," and thrix, "bristle," referring to the pappus (ref. genus Hymenothrix)
  • Hymenox'ys: from the Greek hymen, "a membrane," and oxys, "sharp-pointed, sharp," and apparently alluding to the pappus (ref. genus Hymenoxys)
  • Hyparrhen'ia: from the Greek hypo, "beneath, under, below," and arrhen, "male," alluding to the basal staminate spikelets (ref. genus Hyparrhenia)
  • hypeco'ides: resembling genus Hypecoum (ref. Eschscholzia hypecoides)
  • hyper-: Greek prefix meaning "above, over," as of some characteristic or dimension
  • hyperbor'ea/hyperbor'eal: of the Far North (ref. Platanthera hyperborea)
  • Hyper'icum: an ancient Greek name derived from hyper, "above," and eikon, "picture," from the old practice of placing flowers above an image in the house to ward off evil spirits at the midsummer festival of Walpurgisnacht, which later became the feast of St. John held in late June when they are in bloom, and thus took the name of St. John's wort (ref. genus Hypericum)
  • hypno'ides: moss-like (ref. Eragrostis hypnoides)
  • hypo-: Greek prefix meaning "below, under"
  • Hypochaer'is: it is not clear to me what the derivation of this name is. The entry for Hypochoeris [note spelling] in Stearn's Dictionary of Plant Names says "a name used by Theophrastus for this or a related genus," and Hypochoeris was the named published by Linnaeus in 1753. However he published it subsequently as Hypochaeris, and it may be speculated that the derivation might be different for the two names, although they applied to the same plant. The prefix hypo- means "below, beneath or under," and suggests physical directionality or location, not quantity or amount, as opposed to hyper-, "above or over." Edmund Jaeger's A Source-Book of Biological Names and Terms says that the root chaer- derives from the Greek choiros, "a young pig." The Jepson Manual 1st edition says "Greek: less then joyous, from weedy habitat." The Jepson Manual 2nd edition says "Unabridged note: Etymology differs from that in FNANM, where the etymology on the Greek 'choeris' for pig; the correct spelling is 'chaeris' for joy." Flora of North America says: "Cat’s ear, swine’s succory [Greek hypo, beneath, and choiras, pig, alluding to pigs digging for roots]." (ref. genus Hypochaeris)
  • hypoleu'ca: whitish or pale beneath, as of a leaf (ref. Monardella hypoleuca)
  • hypopit'ys: from the Greek hypo, "under" and pitys, "the pine," thus found under pines (ref. Monotropa hypopitys)
  • hypotrich'ium: from hypo, "below," and trichos, "hair," the original publication mentions that the leaves are hairy below (ref. Galium hypotrichium)
  • Hyp'tis: from the Greek huptios for "turned back," from the lower lip position of the flower (ref. genus Hyptis)
  • hyssopifo'lia/hyssopifolium: having leaves like Hyssop, an aromatic herb in Greece (ref. Bassia hyssopifolia, Corispermum hyssopifolium, Lythrum hyssopifolium)
  • hysterici'na/hystrici'na: although there is still some uncertainty about the spelling of this name, the Jepson Herbarium has apparently decided that it should be spelled hystericina. At this point I'm not sure from what it is derived, but it seems the most likely etymology is from the Greek hystrix, "porcupine" (ref. Carex hystericina)
  • hystric'ula/hystric'ulus: means "like a porcupine," from the Greek hystrix, "a porcupine," probably in reference to the beaked fruits (ref. Kumlienia hystricula, Plagiobothrys hystriculus)
  • hys'trix: bristly, porcupine-like, from the Greek hystrix, "porcupine" (ref. Sitanion hystrix)
