Description: Shrubs.
Leaves alternate, either simple, 3-foliolate, palmate or pinnate with the terminal leaflet sessile; leaflets usually narrow, margins entire; stipules small or absent.
Inflorescences terminal, or rarely axillary, racemes, sometimes reduced to 1 or 2 flowers; bracts usually small, lanceolate; bracteoles small, lanceolate or bristly, inserted ± below the base of the calyx or absent. Calyx tube ± short, the teeth lanceolate, ± equal, longer than tube. Petals shortly clawed; standard circular to reniform, larger than the other petals; wings oblong, ± falcate; keel obtuse, slightly broader than wings. Stamens free. Ovary glabrous, sessile or shortly stipitate; ovules 2–many; style incurved or filiform.
Pod turgid, ± globose to obliquely oblong; seeds without an aril.
Distribution and occurrence: World: >30 species, endemic Australia. Australia: Qld, N.S.W., Vic., Tas., W.A. [includes Burtonia]
