About

Psoralea nitens is an upright, densely branched shrub of up to 1.5 m high that is assigned to the Pea family. It has one to many initially softly hairy stems, alternately set, clover-like, upright leaves crowding the new shoots, and heads consisting of 3 pea-like, dark purple to mauve flowers on short peduncles in the axils of the leaves on short side-shoots. This species is an endemic of the mountains between Ceres and Hottentots Holland in the Western Cape province of South Africa. It mostly flowers between October and late December.
