Monkey thorn is a tall (20 to 30 m), long-lived deciduous tree of Eastern and Southern Africa. Trunks grow to 2 m wide, supporting a wide (10 m), rounded canopy. Young trees have a light-colored (whitish yellow) bark that darkens over time. Branches have pairs of hooked thorns, creamy white flowers, and long reddish purple pods. The leaves allow some sunlight to reach the ground. Leaves are shed during the cool dry season.

Monkey thorn is a valuable timber tree used for construction and fencing. Its flowers attract bees for honey production, and the pods are eaten by livestock and wildlife. It is a soil nitrogen fixing species. It is also sometimes planted as an ornamental tree.
