Herbs, the stem repent and rooting at the nodes, the internodes 1.3-11 cm long. Leaves trifoliolate, stipulate, the stipules connate up to 1/2 their length, early deciduous; petioles to 10 times the length of the leaf rachises, leaf rachis to 12 mm long or occasionally lacking; petiolules of the lateral leaflets usually some-what longer than those of the terminal leaflet. Inflorescence racemose, the ra-cemes arising from the leaf axils; bracts early deciduous; calyx uncinulate pu-berulent over the whole surface with stout straight trichomes along the teeth of both lobes. Flowers with the corolla always exceeding the calyx; standard ob-ovate or more rarely ovate, broadly acute below or narrowing slightly to an obtuse or truncate base, rounded at apex, retuse, the wings obliquely obovate, truncate or obtuse at apex, auriculate at base, short clawed, the keel petals fused, more or less falcate, obtuse at the apex, broadly clawed. Loment 1-3-, mostly 2-articulate, stipitate, the upper suture continuous, essentially straight.
Moist or wet thickets or forest, sometimes in pine forest, often in open weedy places, frequently a weed in banana plantations; at elevations up to 1,000 metres.
Can be grown by cuttings or seedlings. Seeds needs soaking.
