Carpolobia Alba
''Carpolobia alba'' is a plant species in the milkwort family ( Polygalaceae) that is endemic to rainforests, forest fringes, and savanna-park with altitudes below in Western Tropical Africa. It is a shrub or small tree which is tall. Its branches are puberulous or shortly pubescent. Its leaves are membranous A membrane is a selective barrier; it allows some things to pass through but stops others. Such things may be molecules, ions, or other small particles. Membranes can be generally classified into synthetic membranes and biological membranes. ... or slightly leathery. The flowers it produces are yellowish white or white with a crimson spot at the base of upper petals. It produces yellow or scarlet-coloured fruit which are edible and usually contain 3 seeds. It was first described by George Don in 1831. It is used traditionally as a medicine against sexual dysfunction. References Polygalaceae {{Polygalaceae-stub ...

George Don
George Don (29 April 1798 – 25 February 1856) was a Scottish botanist and plant collector. Life and career George Don was born at Doo Hillock, Forfar, Angus, Scotland on 29 April 1798 to Caroline Clementina Stuart and George Don (b.1756), principal gardener of the Royal Botanic Garden Edinburgh in 1802. Don was the elder brother of David Don, also a botanist. He became foreman of the gardens at Chelsea in 1816. In 1821, he was sent to Brazil, the West Indies and Sierra Leone to collect specimens for the Royal Horticultural Society. Most of his discoveries were published by Joseph Sabine, although Don published several new species from Sierra Leone. Don's main work was his four volume ''A General System of Gardening and Botany'', published between 1832 and 1838 (often referred to as Gen. Hist., an abbreviation of the alternative title: ''A General History of the Dichlamydeous Plants''). He revised the first supplement to Loudon's ''Encyclopaedia of Plants'', and provided a ...

Polygalaceae
The Polygalaceae or the milkwort family are made up of flowering plants in the order Fabales. They have a near-cosmopolitan range, with about 27 genera and ''ca''. 900 known species of herbs, shrubs and trees. Over half of the species are in one genus, ''Polygala'', the milkworts. The family was first described in 1809 by Johann Hoffmansegg and Johann Link. In 1896, Robert Chodat split it into 3 tribes. A fourth tribe was split off from the tribe Polygaleae in 1992. Under the Cronquist classification system, Polygalaceae were treated in a separate order of their own, Polygalales. Currently, according to the Angiosperm Phylogeny Group, the family belongs in Fabales. Description ''Polygalaceae'' are annual or perennial herbs, shrubs, shrublets, and small trees. Its zygomorphic, hermaphrodite, bisexual flowers have 3-5 petals and 5 sepals. Its leaves are usually alternate, but may be opposite, fascicled, or verticillate. Each flower usually contain ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pubescent (botany)
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
