Botanist in the context of "Bryophyte"

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.
