The cola seeds of commerce are from medium size spreading trees, up to 40 feet, native to tropical Africa, but now cultivated in the West Indies and other tropical countries. The seeds or nuts are borne in leathery or woody oblong capsules, about 6 inches long. Seeds are near globose, about an inch in diameter. They, or preparations from them, are widely used in tropical countries as a stimulant and appetizer. Preparations from the seeds are widely used for flavoring the cola drinks, very popular in the U.S. and other countries.
