It has shiny green leaves that are either pinnate and up to 30 cm long, or lanceolate. The prominent pinkish-red flower heads appear in spring and summer; these are made up of 50 to 140 individual flowers arranged in corymb or raceme. These are followed by rectangular woody seed pods, which bear two rows of winged seeds. Its terminal globular flowers indicate that the species is pollinated by birds.

The species is a rainforest tree that reaches 25 m high, with a non-buttressed trunk of 1. 5 m diameter at breast height. The bark is greyish brown and covered in many small pimples, rendering it sandpaper-like in texture. The green foliage consists of several distinct juvenile and adult leaf forms, which are arranged alternately along the stems. Among the green foliage there are occasional yellow leaves.
