Large black or dark red speckles often apparent in the outer blaze. Fine, inconspicuous oak grain in the wood and a corresponding lace-like pattern in the inner blaze.
Cotyledons resemble small butterfly wings, each cotyledon +/- reniform, broadly cuneate at the base, about 15-18 x 25-45 mm. At the tenth leaf stage: leaf blade elliptic to narrowly elliptic, apex acute or acuminate, base cuneate or attenuate; terminal bud clothed in prostrate, pink or reddish hairs.
Distribution and Ecology
Endemic to NEQ. Altitudinal range from near sea level to 1200 m. Grows in well developed rain forest on a variety of sites. This species is favoured by disturbance and will successfully invade eucalypt forest in the absence of fire.
A large tree in nature. The juvenile plants have large and attractive leaves and are becoming popular as indoor plants.
Produces a useful general purpose timber but despite the fact that it is a member of the Proteaceae it does not exhibit a conspicuous oak grain.
