The species name refers to the rusty red hair that covers the apical buds, twigs and the base of inflorescence. The midrib of leaves are also sometimes rusty. This medium-sized tree has a straight bole that reaches to about 25 m.

The leaf blades are elliptic-oblong with tips that are bluntly acute annd broadly wedge-shaped bases. The leaves are stiff-leathery. A distinctive characteristic is that the number of veins on the upper surface of leaves appear to be twice that of the lower surface. Flowers are slender-stalked and have sepals with hairy margins. No petals. The fruits are oval in shape, about 3 cm long.
