Chamaecrista pumila


Decumbent or erect, short-lived herb with woody base or undershrub rarely surpassing 50 cm in height; branches pubescent. Leaves with 10-25 pairs of leaflets, sensitive to the touch; stipules linear acute, 5-10 mm, persistent; petiole 5-7 mm, pubescent, provided with a long stipitate gland below the lower pair of leaflets. Flowers supra-axillary, solitary or most often 2 or 3 together in a very short raceme; bracts and bracteoles similar to the stipules, but shorter; pedicels pubescent, 4-6 mm. Sepals lanceolate, acute, 5-6 mm long. Petals bright yellow, unequal, oblong obovate, 2-3 mm long, claw short. Stamens 5, sub- equal; filaments 1-1.5 mm; anthers straight, 1.5-2 mm, opening by apical pores enlarging to short slits. Ovary appressed tomentose; style glabrous, recurved; stigma small, peltate. Seeds 10-15, brown, smooth, flat, subrhomboidal, 3 mm.


Asia-Tropical: Jawa (Jawa present), Flores present, Sumbawa present, Timor present, Tropical Asia to Australia present
Tropical Asia to Australia. Scattered in Malesia, but common only in few areas as e. g. in Sumbawa; there are also several collections from Java, Flores, and Timor.


The petiolar gland shows quite a wide range of variation, but even if it is rather shortly stipitate in some specimens, Chamaecrista pumila is readily distinguishable from C. mimosoides.
