Growing to 20 m tall and 4 m wide, this species has a rough textured shell. The new leaves are red, the flowers are often pinkish and densely covered with hairs. It is often used as a rootstock for known cultivars of macadamias. It is much more adapted to inland conditions and is considered more resistant to the macadamia trunk canker caused by the root fungus Phytophthora cinnamomii. Seedlings of this species are very productive and produce a good edible nut, contrary to many sales peoples' advice.
