A medium to large tree, up to 30 m, which grows on the rocky laterite of the Darling Range. It looks similar to, and is often confused with, Wandoo. Both lose their bark in autumn, but whereas Wandoo’s new bark is cream, that of Powderbark is apricot. Both have smooth bark, but as its common name implies, that of powderbark is powdery, and if rubbed, your hand will be coated with powder.
