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. These cola species are trees native to the tropical rainforests of Africa. Their caffeine-containing seeds are about 5 centimetres (2.0 in) across and are used as flavoring ingredients in various carbonated soft drinks, from which the name cola originates.

Theobroma cacao is a small evergreen tree in the family Malvaceae. Its seeds, cocoa beans, are used to make chocolate liquor, cocoa solids, cocoa butter and chocolate. Native to the tropics of the Americas, the largest producer of cocoa beans in 2018 was Ivory Coast, at 2.2 million tons. Its leaves are alternate, entire, unlobed, 10–50 cm (4–20 in) long and 5–10 cm (2–4 in) broad.
