Walpers, W.G. (1842) Repertorium Botanices Systematicae : 203.
An orange layer usually visible under the dead bark, particularly the thicker areas of dead bark.
Leaf blades about 5-12 x 1.5-3.5 cm, almost white on the underside, particularly the older leaves. Leaf bearing twigs reddish.
Capsules with woody valves. Capsules about 2.5-4 cm long.
Cotyledons elliptic, about 15-20 x 10-15 mm, with a midrib and about four other veins radiating from the base. First pair of leaves with two to three teeth on each side. At the tenth leaf stage: leaf blade margins with four or five sharply pointed teeth on each side; midrib raised on the upper surface; stipules small and inconspicuous, visible only with a lens. Seed germination time 47 days.
There is a chance that this species may have medicinal properties as the inner bark was used in cases of toothache.
This species is one of the few native plants known to have been used as an aphrodisiac by the aborigines. Cribb (1981).
