Its bole is branchless for up to 15 m, measures up to 200 cm in diametre, fluted or with but­tresses up to 1.8 m high. The bark surface is reddish ­brown to yellowish-brown or pale pinkish-brown but sometimes grey or greenish-brown while the inner bark is green.

The flowers are 3-4(-6)-merous, with (5-)6-10(-11) anthers and an ovoid style-head with (2-)3 apical lobes or columnar with a truncate apex. The fruit is (2-)3(-4)-locular and dehiscent.
