Regnum Vegetabile
The International Association for Plant Taxonomy (IAPT) is an organization established to promote an understanding of plant biodiversity, facilitate international communication of research between botanists, and oversee matters of uniformity and stability in plant names. The IAPT was founded on July 18, 1950, at the Seventh International Botanical Congress in Stockholm, Sweden. The IAPT headquarters is located in Bratislava, Slovakia. Its president, since 2017, is Patrick S. Herendeen of the Chicago Botanic Garden; vice-president is Gonzalo Nieto Feliner of the Real Jardín Botánico, Madrid; and secretary-general is Karol Marhold of the Plant Science and Biodiversity Centre, Slovak Academy of Sciences, Bratislava. Both the taxonomic journal ''Taxon'' and the series ''Regnum Vegetabile'' are published by the IAPT. The latter series includes the ''International Code of Nomenclature for algae, fungi, and plants'', ''Index Nominum Genericorum'', and ''Index Herbariorum''. Purpos ...

George Arnott Walker-Arnott
George Arnott Walker Arnott of Arlary (6 February 1799 – 17 April 1868) was a Scottish botanist. Early life George Arnott Walker Arnott was born in Edinburgh in 1799, the son of David Walker Arnott of Arlary. He attended Milnathort Parish School then the High School of Edinburgh. He studied law in Edinburgh. Career Walker Arnott became a botanist, holding the position of Regius Professor of Botany in the University of Glasgow from 1845 to 1868. He studied the botany of North America with Sir William Hooker and collaborated with Robert Wight in studies of Indian botany. He and William J. Hooker went through the Australian collected plant material of Alexander Collie, which was sent back to the UK after his death.Ray Desmond (Editor) He was a member of the Societe de Histoire Naturelle in Paris and the Moscow Imperial Society of Natural History.

William Jackson Hooker
Sir William Jackson Hooker (6 July 178512 August 1865) was an English botanist and botanical illustrator, who became the first director of Kew when in 1841 it was recommended to be placed under state ownership as a botanic garden. At Kew he founded the Herbarium and enlarged the gardens and arboretum. Hooker was born and educated in Norwich. An inheritance gave him the means to travel and to devote himself to the study of natural history, particularly botany. He published his account of an expedition to Iceland in 1809, even though his notes and specimens were destroyed during his voyage home. He married Maria, the eldest daughter of the Norfolk banker Dawson Turner, in 1815, afterwards living in Halesworth for 11 years, where he established a herbarium that became renowned by botanists at the time. He held the post of Regius Professor of Botany at Glasgow University, where he worked with the botanist and lithographer Thomas Hopkirk and enjoyed the supportive friendshi ...

Heinrich Wawra Von Fernsee
Heinrich Wawra Ritter von Fernsee, born Jindřich Blažej Vávra, (February 2, 1831 in Brno, Moravia – May 1887 in Baden bei Wien) was a Czech-Austrian ship surgeon, botanist and explorer. The youngest of five sons of a miller, he studied medicine and botany at the University of Vienna from 1849 to 1855. Upon graduating he joined the Austro-Hungarian Imperial Navy on December 6, 1855. The commander of the fleet at this time was the Archduke Ferdinand Maximilian. Wawra von Fernsee retired from the navy in 1878 to work on his extensive collections. The plant genus '' Fernseea'' was named after him.Genaust, Helmut (1976).

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botanist of the 19th century. His ''Darwiniana'' was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built an extensive ne ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogenetics ...

Houstonia (plant)
''Houstonia'' (bluet) is a genus of plants in the family Rubiaceae. Many species were formerly classified, along with other genera since segregated elsewhere, in a more inclusive genus ''Hedyotis''. Bluets are often small and delicate. For example, ''H. rosea'' may grow only one inch tall. Some species are single stemmed and others have multiple stems in bunches. Flowers are blue, purple, lavender, white, or rose, often with shades of one color present in an individual population. Flowers have 4 sepals, colloquially denominated "petals", a salverform corolla with 4 lobes, and an inferior ovary. Some species exhibit heterostyly. The fruit is an often roughly cordate capsule enclosing many seeds and which usually dehisces via a suture across its apex. ''Houstonia'' consists of 20 species native to North America. Another 5 species are classified in the genus '' Stenaria''; ''Houstonia'' without ''Stenaria'' is paraphyletic. Close relatives of the genus are '' Oldenlandia microth ...

Oldenlandiopsis
''Oldenlandiopsis'' (creeping-bluet) is a genus of flowering plants in the family Rubiaceae. It is monospecific, comprising only one species, ''Oldenlandiopsis callitrichoides''. This species had previously been placed in ''Hedyotis'' or in '' Oldenlandia''. It is native to the West Indies, southern Mexico, and Central America. It is naturalized elsewhere, including Florida, Hawaii, South America, and tropical Africa. ''Oldenlandiopsis'' was established in 1990 by Edward E. Terrell and Walter H. Lewis. The generic name indicates a likeness to ''Oldenlandia''. The specific epithet refers to a superficial resemblance to Callitriche, a genus in Plantaginaceae. ''Oldenlandiopsis callitrichoides'' was first described in 1862 by August Grisebach as ''Oldenlandia callitrichoides'' in a pre-print of a paper that was published the following year in ''Memoirs of the American Academy of Arts and Sciences''. ''Oldenlandiopsis'' is a member of the tribe Spermacoceae. Within the tribe, it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
