Pentodon is a genus of plants belonging to the family Rubiaceae. There appear to be only two species in the genus. They are found in Central America, Central and Southern Africa and the Seychelles. [1]
The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, ornamental cultivars, and historically some dye plants.
Sherardia is a monotypic genus of flowering plants in the family Rubiaceae. The genus contains only one species, Sherardia arvensis, the (blue) field madder, which is widespread across most of Europe and northern Africa as well as southwest and central Asia and Macaronesia. It is also reportedly naturalized in Australia, New Zealand, Taiwan, Kerguelen, Ethiopia, Sudan, southern Africa, Mexico, Costa Rica, South America, Bermuda, Cuba, Haiti and much of Canada and the United States.
Diodia is a genus of flowering plants in the family Rubiaceae. It was described by Carl Linnaeus in 1753. The genus is found from southern and eastern United States, South America, Central America, Mexico, the West Indies and tropical Africa.
Psychotria is a genus of flowering plants in the family Rubiaceae. It contains 1,582 species and is therefore one of the largest genera of flowering plants. The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests. Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific.
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.
Vangueriopsis is a genus of flowering plants in the family Rubiaceae.
Vangueria madagascariensis, commonly known by the names Spanish-tamarind, tamarind-of-the-Indies, or voa vanga, is a species of flowering plant in the family Rubiaceae native to the African continent having edible fruit. It is the type species of the genus Vangueria and was described in 1791 by Johann Friedrich Gmelin.
Fadogiella is a small genus of flowering plants in the family Rubiaceae. It was described by Walter Robyns in 1928.
Atractogyne is a genus of flowering plants in the family Rubiaceae. It is found in western and western-central tropical Africa.
Globulostylis is a genus of flowering plants in the family Rubiaceae. It comprises 8 species growing in Central Africa.
Cornelis Eliza Bertus Bremekamp was a Dutch botanist.
Craterispermum is a genus of flowering plants in the family Rubiaceae. It contains 16 species that occur in tropical Africa and Seychelles. It is the only genus in the tribe Craterispermeae, of which the divergence time is estimated at 34.8 million years ago.
Cremaspora is a genus of flowering plants in the family Rubiaceae. It is the only genus in the tribe Cremasporeae. It was described by George Bentham in 1849. The genus is widespread across much of sub-Saharan Africa from Senegal to Tanzania and south to Mozambique and Zimbabwe, in addition to Madagascar, Comoros, and Cape Verde. There are, however, only two currently recognized species.
Colletoecema is a genus of flowering plants in the family Rubiaceae. It is the only genus in the tribe Colletoecemateae. The 3 species are found from west-central tropical Africa to Angola.
Dictyandra is a genus of flowering plants in the family Rubiaceae. The genus is found in tropical Africa.
Spermacoceae is a tribe of flowering plants in the family Rubiaceae and contains about 1346 species in 57 genera. Its representatives are found in the tropics and subtropics.
Pentodon is the scientific name of two genera of organisms and may refer to:
Dr. Charlotte M. Taylor is a botanist and professor specialising in taxonomy and conservation. She works with the large plant family Rubiaceae, particularly found in the American tropics and in the tribes Palicoureeae and Psychotrieae. This plant family is an economically important group, as it includes plant species used to make coffee and quinine. Taylor also conducts work related to the floristics of Rubiaceae and morphological radiations of the group. Taylor has collected plant samples from many countries across the globe, including Chile, Colombia, Costa Rica, Panama, and the United States of America, and has named many new species known to science from these regions. As of 2015, Taylor has authored 278 land plant species' names, the seventh-highest number of such names authored by any female scientist.
