Leaves with 20-80 pairs of leaflets, sensitive to touch; stipules linear, acute, 5-10 mm, persistent; petioles 3-10 mm, with a flat, discoid, sessile gland just below the lowest pair of leaflets; rachis serrate or crenate, crested along upper side, not canaliculate, sparsely pubescent, 3-10 cm. Flowers supra- axillary, mostly solitary, sometimes 2 or 3 together in a very short raceme; bracts like the stipules; bracteoles similar to the stipules but smaller; pedicels pubescent, 5-10 mm.

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.


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.


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
