Psydrax
''Psydrax'' is a genus of flowering plants in the family Rubiaceae. It consists of trees, shrubs, and a few lianas in the paleotropics. Taxonomy The genus was named by Joseph Gaertner in 1788 in his book, ''De Fructibus et Seminibus Plantarum''. ''Psydrax'' is a Greek word meaning a blister or bump. Gaertner may have chosen this name to refer to the warty fruit or the pimply seeds of some species. The name was hardly ever used after Gaertner proposed it because most authors placed these species in ''Canthium''. ''Psydrax'' was reinstated in 1985 and 37 African species were transferred to it from ''Canthium''. The monospecific genus ''Mesoptera'' was also sunk into ''Psydrax''. ''Psydrax'' was shown to be monophyletic in a molecular phylogenetic study. It is closely related to ''Afrocanthium'', ''Cyclophyllum'' and ''Keetia'', genera that have been segregated from ''Canthium''.

Mitrastigma
''Mitrastigma'' was a monotypic genus of flowering plants in the family Rubiaceae but is no longer recognized. It was originally described by William Henry Harvey in 1842. The genus was monotypic, containing only the one species ''Mitrastigma lucidum''. It was sunk into synonymy with the genus ''Psydrax'', where ''Mitrastigma lucidum'' now appears as the species ''Psydrax ''Psydrax'' is a genus of flowering plants in the family Rubiaceae.

Canthium
''Canthium'' is a genus of flowering plants in the family Rubiaceae. They are shrubs and small trees. The leaves are deciduous and the stems are usually thorny. Distribution ''Canthium'' species are predominantly found in Southeast Asia, especially in Thailand and the Philippines. A small number of species is found in India, Sri Lanka, and Bangladesh. Only a limited number of species is found on the African continent, especially in Southern and East Africa. Taxonomy ''Canthium'' was named by Jean-Baptiste Lamarck in 1785 in Encyclopédie Méthodique. The name is a latinisation of "kantankara", a Malayalam name from Kerala for ''Canthium coromandelicum''. ''Kantan'' means "shining" and ''kara'' means "a spiny shrub". The biological type for the genus consists of specimens originally described by Jean-Baptiste Lamarck as ''Canthium parviflorum''''Canthium'' In: Index Nominum Genericorum.

William Henry Harvey
William Henry Harvey, FRS FLS (5 February 1811 – 15 May 1866) was an Irish botanist and phycologist who specialised in algae. Biography Harvey was born at Summerville near Limerick, Ireland, in 1811, the youngest of 11 children. His father Joseph Massey Harvey, was a Quaker and prominent merchant. William started his education at Ballitore School in County Kildare and by the age of 15 had already established algae as his over-riding interest.Papenfuss, G.F. 1976. pp.21–46. Landmarks in Pacific North American Marine Phycology. ''in'' Abbott, I.A. and Hollenberg, G.J. 1976. ''Marine Algae of California''. Stanford University Press, California. After leaving school he joined the family business. Harvey was an authority on algae and bryophytes ( mosses), and author of ''A Manual of the British Algae'' (1841), ''Phycologia Britannica'' (4 vols., 1846–51), ''Nereis Boreali-Americana.'' (3 parts 1852–85) and '' Phycologia Australica'' (5 vol., 1858–63). He spent several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Joseph Dalton Hooker
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 twenty 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. Biography Early years Hooker was born in Halesworth, Suffolk, England. He was the second son of the famous botanist Sir William Jackson Hooker, Regius Professor of Botany, and Maria Sarah Turner, eldest daughter of the banker Dawson Turner and sister-in-law of Francis Palgrave. From age seven, Hooker attended his father's lectures at Glasgow University, taking an early interest in plant distribution and the voyages of explorers like Captain James Cook. He was educated at the Glasgow High School and went on to study medicine at Glasgow University, graduating M.D. in 1839. This degree qualified him for ...

Segregate (taxonomy)
In taxonomy, a segregate, or a segregate taxon is created when a taxon is split off from another taxon. This other taxon will be better known, usually bigger, and will continue to exist, even after the segregate taxon has been split off. A segregate will be either new or ephemeral: there is a tendency for taxonomists to disagree on segregates, and later workers often reunite a segregate with the 'mother' taxon. If a segregate is generally accepted as a 'good' taxon it ceases to be a segregate. Thus, this is a way of indicating change in the taxonomic status. It should not be confused with, for example, the subdivision of a genus into subgenera. :For example, the genus ''Alsobia'' is a ''segregate'' from the genus ''Episcia''; The genera ''Filipendula'' and ''Aruncus'' are segregates from the genus ''Spiraea''.
