Dwarf Cassia is a subshrub or spreading perennial herb, woody at base,
25-75 cm tall, with many branches. Branches, leaf-stalks and rachises of
leaves are hairy. Leaves are 3-6 cm, with a gland carried on a stipe, on
top of the leaf-stalk and on rachis between lowest pair of leaflets.
Stipules are linear-subulate, 6-8 mm, long-pointed. Leaflets are 12-20
pairs, stalkless, unequally sided, linear-falcate, 8-12 × 2 mm, midrib
near upper margin of blade, tip with a sharp point. Flowers arise in leaf
axils, solitary or most often 2 or 3 together in a very short raceme.
Bracts and bracteoles are similar to stipules but shorter. Sepals are
ovate-oblong, 4-6 mm, tip pointed. Petals are bright yellow, nearly equal,
oblong-obovate, shorter than or about as long as sepals, shortly clawed.
Stamens are 5, nearly equal, anthers oblong. Ovary is stalkless, stigma
peltate, small. Pods are flat, straight, strap-shaped, 3-5 cm long, 0.5 cm
wide, hairy. Seeds are 10-20, subrhomboid, about 3 mm, flat, smooth.
