Inflorescence much shorter than the leaves, barely exceeding the petioles. Pedicels about 3-5 mm long. Corolla tube about 1.5-2 mm long, corolla lobes about 0.5-1 mm long, outer surface minutely papillose. Ovary about 1 x 1 mm, stigma short and capitate, +/- papillose.

Infructescence much shorter than the leaves, barely exceeding the petioles, pedicels about 3-5 mm long. Calyx lobes persistent at the base of the fruit. Fruits globular, about 4 x 4.5 mm. Oil dots visible in the exocarp and in the white fleshed pericarp. Cotyledons about as wide as the radicle or slightly narrower.

Cotyledons ovate, about 9-12 mm long. First pair of leaves obovate with about 3-5 coarse peg-like teeth on each side of the midrib. At the tenth leaf stage: leaf blade ovate, apex acute, base attenuate, margins serrate, about 6-8 teeth on each side of the leaf blade, glabrous; oil dots reddish. Terminal bud clothed in reddish scale-like hairs. Seed germination time 55 to 95 days.

Endemic to Australia, occurs in CYP, NEQ, CEQ and southwards as far as south-eastern New South Wales. Altitudinal range in CYP and NEQ from near sea level to 800 m. Grows in drier, more seasonal rain forest and monsoon forest.
