It is native to nearly all the world's tropics; South America, Africa, Madagascar, the Indian Subcontinent, southern China, southeast Asia, Malesia, Papuasia and Australia, and has been introduced to the Caribbean, the southeast United States, Mexico and Central America. It is used as a green manure and, to a minor extent, for forage.
