Distribution

Africa present, Malesian area present, continental SE Asia present, neotropics present, tropical Asia present
Origin probably in continental SE Asia; it is usually regarded as introduced in the Malesian area and in Africa, as well as in the neotropics. It is a very common species all over tropical Asia.

Taxonomy

Widespread and polymorphous species not yet fully understood; we have not maintained De Wit's forma perennis as this is certainly only one of the several ecotypes.

Uses

Of little use; according to De Wit (l.c.) it has been tried as a green manure in tea plantations on Sumatra. Possible medicinal value is discussed by . See also
