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.
Galium is a large genus of annual and perennial herbaceous plants in the family Rubiaceae, occurring in the temperate zones of both the Northern and Southern Hemispheres. Some species are informally known as bedstraw.
Pyrola chlorantha, the greenflowered wintergreen, is a species of the plant genus Pyrola. It has a circumboreal distribution and is found throughout the northern latitudes of Eurasia and North America.
Asperula, commonly known as woodruff, is a genus of flowering plants in the family Rubiaceae. It contains 194 species and has a wide distribution area from Europe, northern Africa, temperate and subtropical Asia to Australasia.
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.
Platanthera chlorantha, commonly known as greater butterfly-orchid, is a species of orchid in the genus Platanthera. It can be found throughout Europe and Morocco. The name Platanthera is derived from Greek, meaning "broad anthers", while the species name, chlorantha, means "green-flowered".
Pauridiantha divaricata is a species of plant in the family Rubiaceae. It is endemic to Cameroon. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Pauridiantha is an afrotropical genus of plant in family Rubiaceae.
Pauridiantha insularis is a species of plant in the family Rubiaceae. It is endemic to São Tomé Island.
Pauridiantha talbotii, synonym Pauridiantha venusta, is a species of plant in the family Rubiaceae. It is native to Cameroon, Equatorial Guinea, Gabon and Nigeria.
Vanguerieae is a tribe of flowering plants in the family Rubiaceae and contains about 655 species in 30 genera. It is one of the most species-rich groups within the family and it is distributed across the Paleotropics.
Fadogia is a genus of flowering plants in the family Rubiaceae. The genera Rytigynia and Fadogia form a strongly supported clade but neither of these genera is monophyletic.
Vangueriella is a genus of flowering plants in the family Rubiaceae. The genus is found in tropical Africa.
Ixoroideae is a subfamily of flowering plants in the family Rubiaceae and contains about 4000 species in 27 tribes.
Rubioideae is a subfamily of flowering plants in the family Rubiaceae and contains about 7600 species in 27 tribes.
Ferdinandusa is a genus of flowering plants in the family Rubiaceae, native to the American tropics.
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.
Coffea racemosa, also known as racemosa coffee and Inhambane coffee, is a species of flowering plant in the family Rubiaceae. It has naturally low levels of caffeine, less than half of that found in Coffea arabica, and a quarter of that in Robusta coffee. It is endemic to the coastal forest belt between northern KwaZulu-Natal in South Africa and Zimbabwe, found in an area less than 150 km2 (58 sq mi) in size. It was widely cultivated by the Portuguese during the 1960-1970s in Mozambique, currently there are only two plantations at Ibo Island and in Hluhluwe, which remain.
Silene chlorantha is a species of flowering plant belonging to the family Caryophyllaceae.
Annickia chlorantha is a tree that grows up to 25 meters tall, it belongs to the Annonaceae family. An important tree used in traditional medical practices for the treatment of malaria and various diseases in Nigeria and Cameroon; oil extracted from stem barks and leaves of the species and Annickia affinis, its more common close kin have been widely studied.
