Kola Nut

The kola nut is the seed of certain species of plant of the genus Cola, placed formerly in the cocoa family Sterculiaceae, and now usually subsumed in the mallow family Malvaceae (as subfamily Sterculioideae). These species are trees native to the tropical rainforests of Africa. Their caffeine-containing seeds are used as flavoring ingredients in various carbonated soft drinks; the name "cola" for a variety of soft drink is derived from this use.
