He previously spelled his name Acock. (Hugh Clarke)

acocksianum (Troglophyton): see acockii.

acocksii (Agathosma, Asparagus, Cliffortia, Diospyros, Erica, Protoasparagus, Restio, Rhus, Searsia, Selago, Trachyandra): see acockii.
    Protoasparagus acocksii = Asparagus acocksii.
    Rhus acocksii = Searsia acocksii.

adamsonii (Liriothamnus, Trachyandra): after Robert Stephen Adamson (1885-1965). "English botanist from Manchester who was a lecturer in botany at Manchester University (1912-1922) before sailing to Australia (1922), then moving to South Africa where he was appointed Professor of Botany at Cape Town University (1923-1950). Adamson published on the vegetation of South Africa and wrote a flora of the Cape area, eventually retiring to Scotland in 1955." (Aluka)
    Liriothamnus adamsonii = Trachyandra adamsonii.

Adansonia (Bombaceae): named for French surgeon and naturalist of Scottish descent Michel Adanson (1727-1806). Adanson was born at Aix-en-Provence. His family moved to Paris on 1730. After leaving the College Sainte Barbe he was employed in the cabinets of R. A. F. Reaumur and Bernard de Jussieu, as well as in the Jardin des Plantes. At the end of 1748 he left France on an exploring expedition to Senegal. He remained there for five years, collecting and describing numerous animals and plants. He also collected specimens of every object of commerce, delineated maps of the country, made systematic meteorological and astronomical observations, and prepared grammars and dictionaries of the languages spoken on the banks of the Senegal. After his return to Paris in 1754 he made use of a small portion of the materials he had collected in his Histoire naturelle du Senegal (1757). This work has a special interest from the essay on shells, printed at the end of it, where Adanson proposed his universal method, a system of classification distinct from those of Buffon and Linnaeus. He founded his classification of all organized beings on the consideration of each individual organ. As each organ gave birth to new relations, so he established a corresponding number of arbitrary arrangements. Those beings possessing the greatest number of similar organs were referred to one great division, and the relationship was considered more remote in proportion to the dissimilarity of organs. In 1763 he published his Familles naturelles des plantes. In this work he developed the principle of arrangement above mentioned, which, in its adherence to natural botanical relations, was based on the system of Joseph Pitton de Tournefort, and had been anticipated to some extent nearly a century before by John Ray. The success of this work was hindered by its innovations in the use of terms, which were ridiculed by the defenders of the popular sexual system of Linnaeus; but it did much to open the way for the establishment, by means principally of Antoine Laurent de Jussieu's Genera Plantarum (1789), of the natural method of the classification of plants. In 1774 Adanson submitted to the consideration of the French Academy of Sciences an immense work, extending to all known beings and substances. It consisted of 27 large volumes of manuscript, employed in displaying the general relations of all these matters, and their distribution; 150 volumes more, occupied with the alphabetical arrangement of 40,000 species; a vocabulary, containing 200,000 words, with their explanations; and a number of detached memoirs, 40,000 figures and 30,000 specimens of the three kingdoms of nature. The committee to which the inspection of this enormous mass was entrusted strongly recommended Adanson to separate and publish all that was peculiarly his own, leaving out what was merely compilation. He obstinately rejected this advice; and the huge work, at which he continued to labour, was never published. He had been elected a member of the Academy of Sciences in 1759, and he latterly subsisted on a small pension it had conferred on him. Of this he was deprived in the dissolution of the Academy by the Constituent Assembly, and was consequently reduced to such a depth of poverty as to be unable to appear before the French Institute when it invited him to take his place among its members. Afterwards he was granted a pension sufficient to relieve his simple wants. He died at Paris after months of severe suffering, requesting, as the only decoration of his grave, a garland of flowers gathered from the fifty-eight families he had differentiated - "a touching though transitory image," says Georges Cuvier, "of the more durable monument which he has erected to himself in his works."

From 1792 he spent some years on the west coast of Africa, and in 1797-1798 acted as secretary of the Swedish embassy in London. Returning to Sweden, he again took up his position as botanical demonstrator at Uppsala, and was in 1802 elected president of the "Zoophytolithic Society" (later called the Linnaean Institute). In 1812, he became professor of materia medica at the university. He died in Uppsala. In addition to various botanical writings, he published the autobiography of Carolus Linnaeus in 1823. His brother, Johan Afzelius (1753-1837) was professor of chemistry at Uppsala; and another brother, Pehr von Afzelius (1760-1843; the "von" was added when he was ennobled), who became professor of medicine at Uppsala in 1801, was distinguished as a medical teacher and practitioner.

In 1855 Baines joined Augustus Gregory’s 1855–1857 Royal Geographical Society sponsored expedition across northern Australia as official artist and storekeeper. The expedition’s purpose was to explore the Victoria River district in the north-west and to evaluate the entire northern area of Australia in terms of its suitability for colonial settlement. His association with the North Australian Expedition was the highpoint of his career, and he was warmly commended for his contribution to it, to the extent that Mount Baines and the Baines River were named in honour of him. In 1858 Baines accompanied David Livingstone along the Zambezi, and was one of the first white men to view Victoria Falls. In 1869 Baines led one of the first gold prospecting expeditions to Mashonaland in what later became Rhodesia. In 1870 Baines was granted a concession to explore for gold between the Gweru and Hunyani rivers by Lobengula, leader of the Matabele nation. Thomas Baines died in Durban in 1875.

Andrews's "Heathery," published in 1805, Andrews depicted Erica baueri for the first time. He named it after his fellow artist at Kew, Francis Bauer (1758-1810), who was botanical artist to King George III. (PlantzAfrica)

Bauhinia (Fabaceae): the genus Bauhinia was established by Linnaeus in 1753 and commemorates the brothers Gaspard (or Caspar) (1560-1624) and Johann (or Jean) Bauhin (1541-1613) , both botanists and herbalists, the characteristic paired leaves being a reflection of their relationship. "Gaspard Bauhin introduced binomial nomenclature into taxonomy, which was much later taken up by Linnaeus. Bauhin's work, Pinax theatri botanici (1596), was the first to use this convention for naming of species. He also worked on human anatomical nomenclature. His brother, Johann Bauhin, or Jean Bauhin, was also a physician and botanist. Jean and Gaspard were the sons of Jean Bauhin (1511-1582), a French physician who had to leave his native country on becoming a convert to Protestantism. Gaspard was born at Basel and studied medicine at Padua, Montpellier, and in Germany. Returning to Basel in 1580, he was admitted to the degree of doctor, and gave private lectures in botany and anatomy. In 1582 he was appointed to the Greek professorship in that university, and in 1588 to the chair of anatomy and botany. He was later made city physician, professor of the practice of medicine, rector of the university, and dean of his faculty. In addition to Pinax Theatri Botanici, Gaspard planned another work, a Theatrum Botanicum, meant to be comprised in twelve parts folio, of which he finished three; only one, however, was published (1658). He also gave a copious catalogue of the plants growing in the environs of Basel, and edited the works of Pietro Andrea Mattioli (1500-1577) with considerable additions. His principal work on anatomy was Theatrum Anatomicum infinitis locis auctum (1592). (Wikipedia) "Johann studied botany at Tübingen under Leonhart Fuchs (1501-1566). He then travelled with Conrad Gessner, after which he started a practise of medicine at Basel, where he was elected Professor of Rhetoric in 1566. Four years later he was invited to become physician to Duke Frederick I of Württemberg at Montbéliard, where he remained until his death. He devoted himself chiefly to botany. His great work, Historia plantarum universalis, a compilation of all that was then known about botany, was incomplete at his death, but was published at Yverdon in 1650-1651." (Answers.com)

Berardia (Bruniaceae): The Penny Cyclopaedia of the Society for the Diffusion of Useful Knowledge says that this was named by botanist Dominique Villars after an apothecary who was a contemporary of the Bauhins named Berard, who lived at Strasburg and who left behind a manuscript work on plant, however the Aluka database which is probably more reliable has it that it honors M. Berard, Professor of Chemistry at Montpelier. As a further possibility, Paxton's Pocket Botanical Dictionary lists it as honoring Mr. Berard, a botanist of Grenoble.

"The Abbé Jean-Paul Bignon was Royal Librarian at the Bibliotheque Nationale de France from 1718 to 1741, and brought the institution to its glorious zenith. The Bibliotheque had been set up in 1368 by Charles V, 'the Wise', who had moved his personal library of some 917 manuscripts into the Louvre to be cared for by the then Guardian Gilles Malet. The Bibliotheque was moved several times around France, growing in size and diversity under the auspices of several key librarians including the statesman Colbert, who moved the collection to the Paris quarter where it still resides. By the time Bignon arrived in 1719 the library, now the Bibliotheque du Roi, had become the leading library in Europe. The number of volumes it carried had outgrown the most immediate database system of the time, in that the librarians could no longer rely on their memories to find titles. Bignon expanded on the classification system of his predecessor Nicolas Clement - who had divided printed material into 23 categories - by organising the library into five departments, covering Manuscripts, Printed Books, Titles and Genealogy, Engraved Plates and Prints, Medals and Stone Engravings. Bignon made great efforts to add to the library by attempting to procure the major works of European scholars. He also took the unprecedented step of opening the library to the public, but only for three hours one day of the week. Not least by imitating the opening times of some modern libraries, the Abbe established himself as truly being a man ahead of his time." (Digital Handbook of Library Science)

Bijlia (Mesembryanthemaceae): named for Paul Andries van der Byl (Bijl) (1888-1939), a collector of succulents. He was on the staff of the Division of Plant Pathology in Pretoria, then in 1918 he was transferred to Durban as officer in charge of the Botanic Station and Natal Herbarium, to work on diseases of sugar-cane and other tropical crops. In 1921 he was appointed Professor of Phytopathology in the newly formed Agricultural Faculty of Stellenbosch University, the first professor in this subject in South Africa, and built his department up from scratch to a leading place for teaching and research in phytopathology and mycology. He was the first professor of plant pathology in South Africa, and his department was also the first department of plant pathology in the British Commonwealth. In 1928 he became principal of the Stellenbosch Elsenburg Agricultural College, a post he held until his death. During his career he established one of the most extensive lichen collections ever obtained in South Africa, and after his death, the P.A. Van Der Bijl Herbarium was merged with the National Collection of Fungi (PREM). In 1928 he also published the first South African book dealing with diseases of plants. (South African Society of Plant Pathology and CRC World Dictionary of Plant Names) Since I wrote this I have heard from Leonard Newton, co-author of Etymological Dictionary of Succulent Plant Names who said that he was "under the impression that this genus was named for Mrs. Deborah van der Bijl (1872-1942) [wife of Paul Andries?] , founder and first president of the South African Succulent Society in 1931. She collected plants and sent them to, among others, Dr. N.E. Brown, author of the name Bijlia." So this remains uncertain at the moment pending further confirmation one way or the other.

She was artist and engraver for A Curious Herbal which contained illustrations of many odd-looking unfamiliar plants froom the New World. She undertook this job in order to raise funds to secure the release of her husband Alexander Blackwell from debtor's prison. Unfortunately her husband's story did not have a happy ending for after leaving his family and relocating to Sweden, he became involved in a political conspiracy, and was arrested and hanged.

Bolusanthus (Fabaceae): honors Harry Bolus (1834-1911), South African botanist and founder of the Cape Town Bolus Herbarium. "Harry Bolus April 28, 1834 - May 25, 1911 was a South African botanist and businessman. He advanced botany in South Africa by establishing bursaries, founding the Bolus Herbarium and bequeathing his library and a large part of his fortune to the South African College. Active in scientific circles, he was a Fellow of the Linnean Society, member and president of the SA Philosophical Society (later the Royal Society of SA), awarded the SA Medal and Grant by the SA Association for the Advancement of Science and an honorary D.Sc. from the University of the Cape of Good Hope. Volume 121 of Curtis's Botanical Magazine was dedicated to him. He is commemorated in five genera: Bolusia, Bolusafra, Neobolusia, Bolusanthus and Bolusiella, as well as numerous specific names. Bolus was born in Nottingham, England. He was educated at Castle Gate School, Nottingham. The headmaster George Herbert regularly corresponded with and received plant specimens from William Kensit of Grahamstown, South Africa. Kensit requested that the headmaster send him one of his pupils as an assistant; Harry Bolus duly landed at Port Elizabeth from the ship Jane in March 1850. He spent two years with Kensit and then moved to Port Elizabeth. Following a short visit to England, he settled in Graaff-Reinet, where he would live for the next 19 years. In 1857 he married Sophia Kensit, the sister of William Kensit. Between 1858 and 1870 they had 3 sons and a daughter. In 1864 he lost his eldest son, and Francis Guthrie who had become a close friend, suggested his taking up botany to ameliorate his loss. He started his botanical collection in 1865 and was soon corresponding with Joseph Hooker at Kew, William Henry Harvey in Dublin and Peter MacOwan in Grahamstown. In 1875 he joined his brother Walter in Cape Town, where they founded a stockbroking firm. The following year he and Guthrie made their first visit to Kew, taking with them a large number of plant specimens for naming. Returning in the Windsor Castle in October 1876, the ship struck a reef off Dassen Island with the loss of his specimens and notes. Not daunted, he set about the collection of new specimens and organised expeditions to various corners of South Africa. He was an excellent field botanist and published numerous books on his observations. Although adventurous by nature, he was also quiet and unassuming. His business flourished so that many fine botanical books came into his possession. Complete sets of the Botanical Magazine, Botanical Register, Refugium Botanicum, and the large folios of Redout‚ Jacquim, Bauer and Masson formed part of his collection. He founded the Harry Bolus Professorship at the Cape University and left a large trust for scholarships. He also donated his extensive herbarium and library to the South African College. He was one of the founding Members of the South African Philosophical Society. Harry Bolus died at Oxford, Surrey, on the 25th of May, 1911." (Wikipedia)

Borbonia (Lauraceae): genus named by French botanist Charles Plumier for Gaston, Duke of Orleans (1608-1660), third son of Henri IV (Henri de Bourbon). David Hollombe provided the following: "At this period, Gaston of Orleans, brother of Louis XIII., had established a botanical garden at his palace of Blois, which had acquired much celebrity from the works of Morison, and by drawings of the most remarkable plants. Gaston of Orleans, not satisfied with the mere collection of plants of every country in his garden at Blois, had them described by learned botanists, and the most remarkable species drawn on vellum, by the painter Robert, eminent for his skill in that branch of the art."

Berlin Botanical Garden.

bowdenii (Nerine): Some internet sources I found says that N. bowdenii bulbs were first brought to Britain from South Africa by Cornish Bowden in 1903, hence the name. Since websites often just repeat what other websites say, mistakes can proliferate, and many other websites say differently, including this one: "[Nerine] bowdenii commemorates an English traveller, Athelston Bowden, who introduced this species to Britain when he sent bulbs from South Africa to his mother in Cornwall in 1902. Mrs. Bowden is understood to have passed the bulbs to the Botanic Gardens at Kew after they had been flowering in her garden for two years." (www.plant-lives.com). The Dictionary of Plant Names by Allen J. Coombs confirms this latter information, so I think it's probably correct.

    Aloe bradlyana = Haworthia herbacea var. herbacea.

Brasenia (Cabombaceae): "Derivation obscure, apparently from the plant's name in Guiana." Most references indicate derivation obscure. Rafinesque in 1828 said, "from a German botanist, Brasen," with no further details. However, James S. Pringle in a 1995 article in Sida, Contributions to Botany ("Possible Eponomy of the Generic Name Brasenia") suggests that there is good circumstantial evidence that the name does honor Christoph Brasen (1738-1774), a Danish surgeon and leader of the 1771 missionary expedition that established the Moravian mission of Nain on the coast of Labrador the purpose of which was to convert the Inuit residents there to Christianity, and served as its first superintendent. He died in 1774 when on the return trip a storm struck the exploratory voyage he was undertaking to explore the northern Labrador coast and establish a second mission post. The genus was named by Johann Christian Daniel von Schreber who was a professor of natural history and director of the botanical garden at Erlangen, Bavaria. He was familiar with the Moravians and frequently received collected plant specimens from them. Brasen is known to have collected botanical specimens in Labrador and had developed a reputation for being "knowledgeable in botany."

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"

duckittiae (Cenia, Cotula): after Miss Hildagonda Johanna Duckitt (1840-1905), according to Gunn & Codd. She was the sixth child of Frederick Duckitt. 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 indicates that it commemorates a woman. 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 collected and more than one Duckitt may have been honored buy the assignment of their name to a taxon.

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.

At the time, Guthrie was a student of Augustus De Morgan at University College, London. He obtained his B.A. in 1850, and LL.B. in 1852 with first class honours. While coloring a map of the counties of England, he noticed that at least four colors were required so that no two regions sharing a common border were the same color. He postulated that four colors would be sufficient to color any map. This became known as the Four Color Problem, and remained one of the most famous unsolved problems in topology for more than a century, until it was eventually proven in 1976 using a controversial computer-aided proof which was lengthy and inelegant. Guthrie eventually moved to South Africa in 1861 and took up the post of mathematics master at the Graaff-Reinet College. While there he gave some lectures in botany and thus started a life-long friendship with local resident Harry Bolus. He advised Bolus to take up the study of botany to assuage his grief at the loss of his son. When Bolus left for Cape Town a few years later, he persuaded Guthrie to move there as well. For a while he practised at the Bar and edited a newspaper before becoming professor of mathe-
matics at the South African College, which later became the University of Cape Town. He remained there from 1876 until he retired in 1898. When Bolus undertook to do the family of Ericaceae for Flora Capensis, he enlisted Guthrie's aid and they collaborated until Guthrie's death. Before his death, Guthrie had made an extensive collection of the Cape Peninsula flora, which was eventually housed as the Guthrie Herbarium in the University of Cape Town Botany Department, and used for teaching and reference.
