Sapwood surface corrugated. A thin, cream layer normally visible under the subrhytidome layer before the first section of the outer blaze.

Lateral veins curving inside the blade margin. Compound leaf rhachis with a median ridge running along the upper surface at least on the leaflet bearing section. Leaflet stalks swollen and transversely wrinkled. Leaflet blades about 6-19.5 x 2.8-5.5 cm. Domatia are small foveoles.

Calyx about 2 mm long, puberulous. Petals subrhomboidal, about 2 mm long. Disk +/- yellow in colour. Anthers pubescent.

Fruits 1 or 2-lobed, about 5-15 mm diam., loculicidally dehiscent. Valve margins pubescent on inner surface. Aril almost completely enclosing the seed.

First pair of leaves usually compound with two leaflets. At the tenth leaf stage: leaflet blades elliptic or narrowly elliptic, apex acute or acuminate, base cuneate or attenuate, slightly unequal-sided, foveoles small and inconspicuous (visible with a lens); midrib raised on the upper surface; terminal bud clothed in short, pale, prostrate hairs. Seed germination time 21 to 97 days.

Probably endemic to Australia, occurs in CYP, NEQ, CEQ and southwards to coastal central New South Wales. Altitudinal range from near sea level to 900 m. Grows in drier, more seasonal rain forest.
