Shrub to 1 m high, with lignotuber. Branchlets terete or ridged with faint decurrent leaf bases, not glandular-verrucose, hirsute with simple (rarely stellate) hairs. Leaves trifoliolate; petiole 0.1–1.3 mm long, hairy or glabrous; central leaflet narrowly lanceolate to linear, 2.5–8 (–12.5) mm long, 0.9–4.2 mm wide, dentate, revolute at margins, acute; both surfaces not or rarely slightly glandular-verrucose, glabrous to slightly hirsute usually with simple and few bifid hairs, very rarely with stellate hairs (Moura, Queensland); midrib slightly glandular-verrucose, hirsute or glabrous; secondary venation obscure on abaxial surface. Inflorescences longer than leaves (shorter in specimens from Amiens), 1–13-flowered. Sepals 1.3–1.7 mm long, not or slightly glandular-verrucose, hirsute or occasionally glabrous. Petals imbricate, 4.4–5.8 mm long, pale to deep pink, pubescent on both surfaces. Filaments glandular-verrucose apically, dilated basally. Cocci commonly apiculate, glandular-verrucose, glabrous or occasionally hirsute.
