Botanist in the context of Scientist

Forsythia /fɔːrˈsɪθiə/, /fɔːrˈsaɪθiə/ is a genus of flowering plants in the olive family Oleaceae. There are about 11 species, mostly native to Eastern Asia, but one native to Southeastern Europe. Forsythia – also one of the plant's common names – is named after the botanist William Forsyth.

Sir Arthur George Tansley FLS, FRS (15 August 1871 – 25 November 1955) was an English botanist and a pioneer in the science of ecology.

Educated at Highgate School, University College London and Trinity College, Cambridge, Tansley taught at these universities and at Oxford, where he served as Sherardian Professor of Botany until his retirement in 1937. Tansley founded the New Phytologist in 1902 and served as its editor until 1931. He was a pioneer of the science of ecology in Britain, being heavily influenced by the work of Danish botanist Eugenius Warming, and introduced the concept of the ecosystem into biology. Tansley was a founding member of the first professional society of ecologists, the Central Committee for the Survey and Study of British Vegetation, which later organised the British Ecological Society, and served as its first president and founding editor of the Journal of Ecology. Tansley also served as the first chairman of the British Nature Conservancy.

Antarctic flora are a distinct community of vascular plants which evolved millions of years ago on the supercontinent of Gondwana. In 2025, species of Antarctica flora reside on several now separated areas of the Southern Hemisphere, including southern South America, southernmost Africa, New Zealand, Australia, and New Caledonia. Joseph Dalton Hooker (1817 – 1911) was the first to notice similarities in the flora and speculated that Antarctica had served as either a source or a transitional point, and that land masses now separated might formerly have been adjacent.

Based on the similarities in their flora, botanist Ronald D'Oyley Good identified a separate Antarctic Floristic Kingdom that included southern South America, New Zealand, and some southern island groups. In addition, Australia was determined to be its own floristic kingdom because of the influx of tropical Eurasian flora that had mostly supplanted the Antarctic flora and included New Guinea and New Caledonia in the Paleotropical floristic kingdom.

William Forsyth (1737 – 25 July 1804) was a Scottish botanist. He was a royal head gardener and a founding member of the Royal Horticultural Society. A genus of flowering plants, Forsythia, is named in his honour.

Ibn Bassal (Arabic: ابن بصال) was an 11th-century Andalusian Arab botanist and agronomist in Toledo and Seville, Spain who wrote about horticulture and arboriculture. He is best known for his book on agronomy, the Dīwān al-filāha (An Anthology of Husbandry).

Konstantin Sergeevich Mereschkowski (Russian: Константи́н Серге́евич Мережко́вский, IPA: [mʲɪrʲɪˈʂkofskʲɪj]; 4 August 1855 [O.S. 23 July] – 9 January 1921) was a Russian biologist and botanist, active mainly around Kazan, whose research on lichens led him to propose the theory of symbiogenesis – that larger, more complex cells (of eukaryotes) evolved from the symbiotic relationship between less complex ones. He presented this theory in 1910, in his work, The Theory of Two Plasms as the Basis of Symbiogenesis, a New Study of the Origins of Organisms, although the fundamentals of the idea had already appeared in his earlier 1905 work, The nature and origins of chromatophores in the plant kingdom.

Henry Chandler Cowles (February 27, 1869 – September 12, 1939) was an American botanist and ecological pioneer. A professor at the University of Chicago, he studied ecological succession in the Indiana Dunes of Northwest Indiana. This led to efforts to preserve the Indiana Dunes. One of Cowles' students, O. D. Frank continued his research.

Heinrich Karl Walter (21 October 1898 – 15 October 1989) was a German-Russian botanist and eco-physiologist.

An L-system or Lindenmayer system is a parallel rewriting system and a type of formal grammar. An L-system consists of an alphabet of symbols that can be used to make strings, a collection of production rules that expand each symbol into some larger string of symbols, an initial "axiom" string from which to begin construction, and a mechanism for translating the generated strings into geometric structures. L-systems were introduced and developed in 1968 by Aristid Lindenmayer, a Hungarian theoretical biologist and botanist at the University of Utrecht. Lindenmayer used L-systems to describe the behaviour of plant cells and to model the growth processes of plant development. L-systems have also been used to model the morphology of a variety of organisms and can be used to generate self-similar fractals.

Abū Ḥanīfa Aḥmad ibn Dāwūd Dīnawarī (Arabic: أبو حنيفة أحمد بن داود الدينوري; died 895) was an Islamic Golden Age polymath: astronomer, agriculturist, botanist, metallurgist, geographer, mathematician, and historian.

Sir Joseph Dalton Hooker (30 June 1817 – 10 December 1911) was a British botanist and explorer in the 19th century. He was a founder of geographical botany and Charles Darwin's closest friend. For 20 years he served as director of the Royal Botanical Gardens, Kew, succeeding his father, William Jackson Hooker, and was awarded the highest honours of British science.

The Antarctic floristic kingdom, also the Holantarctic kingdom, is a floristic kingdom that includes most areas of the world south of 40°S latitude. It was first identified by botanist Ronald Good, and later by Armen Takhtajan. The Antarctic Floristic Kingdom is a classification in phytogeography, different from the Antarctic realm classification in biogeography, and from Antarctic flora genera/species classifications in botany.

Wilhelm Philippe Schimper (January 12, 1808 – March 20, 1880, in Lichtenberg) was an Alsatian botanist with French, later German citizenship. He was born in Dossenheim-sur-Zinsel, but spent his youth in Offwiller, a village at the foot of the Vosges mountain range in Alsace. He was the father of botanist Andreas Franz Wilhelm Schimper (1856–1901), and a cousin to naturalist Karl Friedrich Schimper (1803–1867) and botanist Georg Heinrich Wilhelm Schimper (1804–1878).

Martinus Willem Beijerinck (Dutch pronunciation: [mɑrˈtinʏs ˈʋɪləm ˈbɛiərɪŋk], 16 March 1851 – 1 January 1931) was a Dutch microbiologist and botanist who was one of the founders of virology and environmental microbiology. He is credited with the co-discovery of viruses (1898), which he called "contagium vivum fluidum".

Johannes Reinke (February 3, 1849 – February 25, 1931) was a German botanist and philosopher, born in Ziethen, Lauenburg. He is remembered for his research of benthic marine algae.

Jacques Daléchamps (1513, Caen – 1588) was a French botanist and physician.

He was the pupil of Guillaume Rondelet and became physician of the Hôtel-Dieu de Lyon.

Gaspard Bauhin or Caspar Bauhin (Latin: Casparus Bauhinus; 17 January 1560 – 5 December 1624), was a Swiss botanist whose Pinax theatri botanici (1623) described thousands of plants and classified them in a manner that draws comparisons to the later binomial nomenclature of Linnaeus. He was a disciple of the famous Italian physician Girolamo Mercuriale and he also worked on human anatomical nomenclature.

Bauhin described the ileocecal valve in 1588—hence the name Bauhin's Valve or Valve of Bauhin—in the preface of his first writing, De corporis humani partibus externis tractatus, hactenus non editus. Linnaeus honored the Bauhin brothers Gaspard and Jean in the genus name Bauhinia.

Buddleja (/ˈbʌdliə/; orth. var. Buddleia; also historically given as Buddlea) is a genus comprising over 140 species of flowering plants endemic to Asia, Africa, and the Americas. The generic name bestowed by Linnaeus posthumously honoured Adam Buddle (1662–1715), an English botanist and rector, at the suggestion of William Houstoun. Houstoun sent the first plants to become known to science as buddleja (B. americana) to England from the Caribbean about 15 years after Buddle's death. Buddleja species, especially Buddleja davidii and interspecific hybrids, are commonly known as butterfly bushes and are frequently cultivated as garden shrubs. Buddleja davidii has become an invasive species in both Europe and North America.

Frederick Campion "Camp" Steward FRS (16 June 1904 – 13 September 1993) was a British botanist and plant physiologist.
