Chamaecrista leschenaultiana (Dc.) O.Deg.

Herb with woody base or low shrub up to 1.5 m high, erect or decumbent; branches more or less densely greyish to yellowish pubescent. Leaves with 10-30 pairs of leaflets; stipules persistent, linear, acute, 10-15 mm long; petioles 3-10 mm with a slightly elevated, discoid gland just below the lowest pair of leaflets; rachis 5-12 cm, pubescent, canaliculate, i.e. with 2 parallel crests along the upper side; sometimes in dried specimens close together. Leaflets sessile, sensitive to touch (but less so than in C. mimosoides), very unequal-sided, more or less falciform, 5-12 by 2-3 mm, glabrous, with ciliate margins; apex rounded oblique, mucronate. Flowers in few-flowered, short, axillary or supra-axillary racemes; bracts and bracteoles like the stipules but smaller; pedicels pubescent, 7-10 mm long. Petals yellow, unequal, lanceolate to obovate, 6-15 mm long, claw short. Stamens (4-)9-10; filaments very short; anthers 5-8 mm, opening by apical pores. Ovary woolly with long and short, thin hairs; style glabrous, recurved; stigma flat, ciliate. Pods flat, strap-shaped, dehiscent, with long and short non-appressed hairs to nearly glabrous, 3-5 by 0.5 cm. Seeds 10-15, black, smooth, flat, 4 by 3 mm.
