Native to the dry forests and coastal scrub of northeastern Australia, the tree has smooth green bark and a pyramidal shape when young. With age, the bark becomes cracked and gray, and the tree's canopy a bit more muscular and spreading. Tap the trunk and it sounds hollow, although packed with fibers
Each leaf is bluish green with fuzzy grayish white undersides. Leaf shape is typically a five-lobed star, but older trees' leaves produce more shallowly lobed foliage.
