The thick outer bark is grey-brown, fissured, and peeling in small flakes. Wood straw- coloured. Cut stems exude brown latex. The thick petals are yellow-green.
The flower and fruit are typical of this well- defined genus, but the branching of the inflorescence is unlike that found in all other species.
