Professor Werner de Lachenal (1736–1800), eminent Swiss botanist and professor of botany and anatomy at the University of Basel 1776-1780, known for his knowledge of European plants. He obtained his Ph.D in 1763. He was a pupil of Haller who was one of his main correspondents providing him with details of flora and their location around Basel, Jura and Alsat. He was a friend of Linnaeus, and authored several monographs in Acta Helvetica. While at the University, he substantially improved the University’s botanical garden, the oldest in Switzerland, which had fallen into disrepair. He continually strived to obtain funds to reconstruct and develop the garden and to pay for the gardener, opening the garden to the public to cover expenditures. The genus Lachenalia in the Hyacinthaceae was published in 1784 by Austrian chemist and botanist Joseph Franz von Jacquin. The CRC World Dictionary of Plant Names, Tropicos and the Harvard University Herbarium database of botanists all give his birth year as 1736 although PlantzAfrica records it as 1739.

Peter Lauremberg (1585-1639) (also called Petrus Laurembergius), German botanist, Rector of the University of Rostock, and professor at one time or another of subjects such as philosophy, mathematics, physics, poetry and medicine. He wrote a work called Horticultur apublished in 1631 which described what was probably the first experiment in allelopathy, the biological phenomenon by which an organism produces one or more biochemicals that influence the growth, survival, and reproduction of other organisms. He also wrote Apparatus Plantarius Primus (1632), a work on bulbous and tuberous plants and their medicinal and culinary uses and their care and propagation, and was primarily responsible for Acerra Philologica, a 2,000 page reference work on the ancient world. His brother John (1590-1658) was a Greek and Latin poet, historian and mathematician. The genus Laurembergia in the Haloragaceae was published in 1767 by Swedish physician and professor of natural history Peter Jonas Bergius. (CRC World Dictionary of Plant Names)

The Lavater brothers, Johann Heinrich Lavater (1611-1691), Swiss physician, professor of medicine and natural history at the Collegium Carolinum, Zurich, and Johann Jacob (1594-1636), also a physician and naturalist, and about whom little else seems to be known. Their father, Heinrich Lavater (1560-1623), was a physician, and professor of physics and mathematics in Zurich. Hugh Clarke adds: "Johann Heinrich obtained his doctorate in Basel in 1647, became town physician in Bern in 1653 and later worked in Zurich where he drew up the Zurich Ordinance in 1668 relating to the plague." The genus Lavatera in the Malvaceae was published by Linnaeus in 1753. (CRC World Dictionary of Plant Names)

James Lee (1715-1795), Scottish nurseryman, senior partner in the Vineyard Nursery, the famous firm of nurserymen Lee & Lewis Kennedy of Hammersmith, London, the largest commercial distributor of protea plants during the late 18th and 19th centuries, which occupied the same site from 1745 to 1890. Lee walked from his home in southern Scotland to London in 1732, began the nursery in 1745 and published in 1760 An Introduction to Botany. He became an international figure in horticulture and was widely known for introducing many new plants. He was friends with Sir Joseph Banks, and his daughter Ann became a botanical artist of note. His second partner was named John Kennedy. There were at least four generations of Lees that ran the nursery, first James Lee, then his son James Lee, third John and Charles Lee, and fourth William Lee. He is commemorated with the former taxon Philippia leeana, now Erica exleeana. (James Lee and the Vineyard Nursery, Hammersmith, by E.J. Wilson; Journal of Horticulture and Practical Gardening, Vol. 3)

Maximilian Leichtlin (1831-1910), German plant collector and botanist. He cultivated rare plants of which bulbs and tubers were his favorites, founded a botanical garden in Baden-Baden, and was one of the first to systematically hybridize orchids. Freesia leichtlinii is one of the taxa which bear his name. He is also commemorated with the former Haplocarpha leichtlinii (now H. lyrata) and probably Gladiolus leichtlinii (now listed as G. dalenii). (JSTOR)

Jules Paul Benjamin delessert (De Lessert)(1773-1847), a French industrialist, banker, amateur botanist and conchologist, owner of an important private herbarium used by Swiss botanist Augustin Pyramus De Candolle and editor of the Icones selectae (1820-1846). He was an artillery officer in the Army, founded the first cotton factory, developed the manufacture of sugar from sugar beets, sat in the Chamber of Deputies, and helped to found the first savings bank in France. He had a botanical library containing some 30,000 volumes, and was the author of Des avantages de la caisse d'épargne et de prévoyance (1835), Mémoire sur un projet de bibliothèque royale (1836), Le Guide de bonheur(1839), and Recueil de coquilles décrites par Lamarck (1841–1842). The genus Lessertia in the Fabaceae was published in his honor by de Candolle in 1802. (PlantzAfrica; CRC World Dictionary of Plant Names; Wikipedia)

Dr. Margaret Rutherford Bryan Levyns (née Michell) (1890-1975), prominent phytogeographer, botanist and taxonomist, lecturer in the Botany Department at the University of Cape Town between c.1955 and 1970, published A Guide to the Flora of the Cape Peninsula in 1929 and major sections of Flora of the Cape Peninsula by Adamson & Salter in 1950. She was the first woman to receive a D.Sc. degree from the University of Cape Town. In 1923 she married John Edward Philpott Levyns (1897-1984), later Assistant Provincial Secretary of the Cape Province who was on the council of the Botanical Society of South Africa. She is commemorated with Psilocaulon levynsiae, Ruschia levynsiae, Wahlenbergia levynsiae, Selago levynsiae, Nivenia levynsiae, Thamnochortus levynsiae, Calopsis levynsiae, Crassula levynsiae (now synonymized to C. natans), Mesembryanthemum levynsiae (now Antimima pumila), Isolepis levynsiana, Nestlera levynsae (now Rosenia oppositifolia), and probably also for Phylica levynsiae, Ficinia levynsiae and Polygala levynsiana.

Martin Heinrich Karl von Lichtenstein (1780-1857), German zoologist, herpetologist and botanist, naturalist, traveller, surgeon, director of the Zoological Gardens in Berlin, author, botanical explorer in the Cape, friend of Poleman, and brother of August Gerhard Gottfried Lichtenstein (1780-1851) who produced an index of plant genera called Index alphabeticus filicum in Caroli a Linné Specierum plantarum. After travelling to southern Africa, He became the personal physician to the Dutch Governor of the Cape of Good Hope. He published Reisen im südlichen Afrika (Travels in Southern Africa) in 1810. In the fields of herpetology and ornithology he described many new species of amphibians, birds and reptiles. He supposedly died at sea of wounds received as a consequence of a duel. He was commemorated with the taxa Barleria lichtensteiniana, Trigonocapnos lichtensteinii, Solanum lichtensteinii, Metalasia lichtensteinii, Gazania lichtensteinii, Anthospermum lichtensteinii (now synonymized to A. ericifolium), Ornithoglossum lichtensteinii (now O. undulatum) and probably for Adenogramma lichtensteiniana. The genus Lichtensteinia in the Apiaceae was published in 1826 by French botanist Ludolf Karl Adelbert von Chamisso (born Louis Charles Adélaïde de Chamissot) and German botanist Diederich Franz Leonhard von Schlechtendal, and the genus Lichtensteinia in the Colchicaceae was published in 1808 by German botanist Carl Ludwig von Willdenow.

Some confusion has arisen regarding this epithet. The genus Lindbergia in the Leskeaceae was published in 1897 by the Swedish bryologist Nils Conrad Kindberg. In 1968 the Irish botanist Norman Loftus Bor published the epithet Lindbergia in the Poaceae, but probably because the name had already been used he changed it to Lindbergella the following year. Tropicos now considers Lindbergia Bor to be an illegitimate name. What was called for a time Lindbergia Bor was named in honor of Harald Lindberg (1871-1963), Finnish/Swedish botanist, taxonomist and entomologist, author of Enumeratio plantarum in Fennoscandia orientali sponte et sunsponte nascentium and many other publications, younger brother of the famous pomologist Björn Lindberg (1860-1954), and an authority on Mediterranean plants. He was the son of the noted bryologist and Professor of Botany Sextus Otto Lindberg (1835-1889). He was accepted as a member of the Societa pro Fauna et Flora Fennica in 1889 (aged 18). His career at the University of Helsinki spanned some 44 years. He had a collection of 50,000 herbarium sheets, representing 13,000 taxa which he deposited at the herbarium in Helsinki. He was awarded the Linnaeus Medal in 1926 by the Swedish Royal Academy of Sciences. This genus (currently Lindbergella) does not appear in South Africa. The genus Lindbergia which does appear in South Africa is the one in the Leskeaceae which was named for Harald Lindberg's father, the great Swedish physician and bryologist Sextus Otto Lindberg (1835-1889), specialist on mosses and hepaticae (liverworts). He worked in the Grand Duchy of Finland, then part of the Russian Empire, then became professor of botany, and dean of the physics-mathematics faculty, at the University of Helsingfors. He made two trips to England in 1872 and 1873, visiting Kew and Oxford, and spent time collecting hepaticae in Ireland. He published numerous papers in Swedish, Latin, English, French and German. He succeeded William Nylander to the chair in botany at the Botanical Museum in Helsingfors and was also appointed Director of the Botanical Gardens there.

John Lindley (1799-1865), one of the giants of British botany, colleague of Hooker, Banks and Bentham, and the first professor of botany at London University and later professor of botany at Cambridge University, specialist in orchid classification and plant systematics in general, author of numerous botanical and horticultural publications, regarded as the foremost British orchidologist of the nineteenth century having established some 120 genera of orchids. He was also an administrator, professor, horticulturist, taxonomist, editor, journalist and botanical artist. His "Report to Treasury and Parliament" was largely responsible for the saving of the Royal Garden at Kew from destruction in 1838. He was the author of Rosarum monographia; or a Botanical History of Roses (1820), An Outline of the First Principles of Horticulture(1832), The Genera and Species of Orchidaceous Plants (1835), The Theory and Practice of Horticulture (1840), Pomologia Brittannica (1841), The Vegetable Kingdom (1846), and many other significant works. He was elected a fellow of the Linnean Society of London at the tender age of 21, and he was the editor for many years of The Botanical Register. I can find reference to only a single trip abroad, to Vichy in France toward the end of his life for health reasons, but JSTOR records list him as a plant collector in Mexico and Madagascar. His name was placed on hundreds of species, and it seems reasonable to assume (but it is only an assumption) that he is the one honored by the orchid taxa in southern Africa such as Disperis lindleyana, Holothrix lindleyana (now H. parviflora) and Satyrium lindleyanum (now S. retusum).
