Cola is a genus of trees native to the tropical forests of Africa, classified in the family Malvaceae, subfamily Sterculioideae (previously in the separate family Sterculiaceae). Species in this genus are sometimes referred to as kola tree or kola nut for the caffeine-containing fruit produced by the trees that is often used as a flavoring ingredient in beverages. The genus was thought to be closely related to the South American genus Theobroma, or cocoa, but the latter is now placed in a different subfamily. They are evergreen trees, growing up to 20 m tall (about 60 feet), with glossy ovoid leaves up to 30 cm long and star-shaped fruit.[1]
Origin and distribution[edit]
Cola is a genus of the Family Malvaceae with approximately 100 to 125 species occurring in the evergreen lowland and montane forest of continental (primarily tropical) Africa.[2] The earliest known evidence of Cola is Cola amharaensis, a well-preserved fossil leaf compression from the late Oligocene Guang River flora of Ethiopia and dated to 27.23 ± 0.1 Ma.[3][4] Kola nuts are seeds harvested from pods, primarily from the species Cola nitida and Cola acuminata.[2] Outside mainland Africa, some species are cultivated for their nuts in Brazil, Jamaica and elsewhere in the humid tropics.
