摘要：Author Henri-Noël Le Houérou 327, rue de Jussieu, 34090 Montpellier, France Page(s) : 117-22 Published in: 1997 The African continent and islands that skirt it include some 68 500 species of vascular plants. On average, almost one new species from the continent or Madagascar is described daily. Africa is also the genetic source of a high number of crop species; 70% of tropical fodder grasses cultivated in the world and 25% of legumes are originally from Africa. The following are among the most common African plants cultivated in the world: coffee, vanilla, yam, sorghum, cow pea, pearl millet (in part), finger millet, castor bean, water melon, rice (in part), oil palm, date palm (in part), wheat (in part), fig (in part), and vines (in part). Furthermore, a number of African crops are specific to the continent, such as tef, ensete, qat, shea butter, African locust, cola, bambara nut, sesame (in part), nugh, gombo, karkadeh (guinean sorrel), corette (melukhia) and many others.
