A shrub or small tree. The small branches have ridges along them. They have rusty hairs. The leaves have 1 or 2 leaflets along the stalk. The leaf stalks have rusty hairs. The leaves are oval and 6-22 cm long by 3-7 cm wide. The fruit is 5-7 mm across and has 4-6 seeds.
Wide-spread, but scattered, in secondary vegetation, apparently rather rare in Malaya and Borneo, up to 1400 m but usually at lower altitudes.
