Usually flowers and fruits as a shrub about 1-3 m tall.
Flowers often viscous. Pedicels about 4-7.5 mm long. Tepals mainly glabrous, margins ciliate, about 1.5-2.5 x 0.8-1.5 mm. Stamens usually eight (ranging from 6-10) usually longer than the tepals, filaments about 0.3-0.5 mm long, anthers about 1.8-2.4 x 0.8-1 mm. Ovary +/- triangular in transverse section. Ovules 1 per locule. Style and stigmas together more than twice the length of the ovary.
Cotyledons +/- linear, about 18 x 3 mm. First pair of leaves usually with some indication of lobing at least towards the apex of the leaf blade. At the tenth leaf stage: leaf blade narrowly elliptic, apex acute and mucronate, base attenuate, midrib raised on the upper surface of the leaf blade. Leaf blade glandular. Seed germination time 18 days.
Occurs in CYP, NEQ, CEQ and southwards as far as north-eastern New South Wales. Altitudinal range from near sea level to 450 m. Usually grows in open forest but also found in vine thickets, monsoon forest, beach forest and on rain forest margins. A typical fire weed often regenerating profusely following bush fires. Also occurs in America, Africa, Asia and Malesia.
The plant contains tannin and is astringent; one variety has been used in Cape York Peninsula by Aborigines in the form of a root decoction for cuts and open wounds. Leaves of this species have been chewed in Peru as a stimulant in the same way as are coca leaves. The leaves and bark have been shown to contain an alkaloid. Cribb (1981).
