Leaves usually alternate but occasionally opposite or in whorls of 3, simple or 1-foliolate, margins entire; stipules scarious, fused for part or most of their length behind the petiole.
Flowers usually orange-yellow with reddish markings, axillary but often crowded in apparently terminal heads; bracteoles attached to the calyx tube or rarely to the pedicel, 1–3-lobed (lateral lobes stipules). Standard equal to or longer than the lower petals. Stamens free. Ovary pubescent to glabrous, sometimes glabrous except for a tuft of hairs near the apex; style filiform; ovules 2.
