The Acorn Banksia is a large shrub or tree with smooth grey bark growing to ten metres in height. The leaves are long and narrow growing to about 25 cm long and 2 cm wide with triangular lobes on the margins making a distinctive saw-toothed edge. It produces acorn-shaped spikes of orange flowers in autumn and winter. The flower buds are woolly white before they open, and open from the bottom of the spike giving the acorn-like appearance. The attractive flowers are popular as cut flowers. The fruit is a woody cone with up to sixty follicles which contain the seed.

Acorn Banksia is endemic to Western Australia where it is found on the west coast from Shark Bay in the north, down past Perth to within a couple of hundred kilometres of Albany.
