Leaves digitately trifoliolate; petiole (3-)4-7(-12) mm long; leaflets oblanceolate to obovate, (2-)4-7(-14) mm long, (1-)2-3(-4) mm wide, sparsely pubescent when young, almost totally glabrous when mature. Stipules consistently present, paired at each node, often very dissimilar in size and shape, broadly lanceolate to broadly ovate, usually asymmetrically lobed at the base, up to 2.5 mm long, or small and linear. Inflorescences leaf-opposed, short congested racemes, up to 10 mm long, 1-4-flowered; bracts up to 1.5 mm long; bracteoles consistently present, small but well-developed, up to 0.5 mm long. Flowers 4-5 mm long, yellow; pedicel 1-2 mm long. Calyx up to 3.5 mm long, with the lateral lobes on either side fused higher up in pairs, glabrous. Standard narrowly elliptic, 4-5 mm long, glabrous. Wing petals weakly developed, very narrowly elliptic, shorter than the keel; auricle and pocket absent; sculpturing absent. Keel petals oblong, obtuse, only slightly auriculate; pocket absent. Anthers dimorphic, spherical and ovoid. Carpel 4-4.5 mm long; ovary short, oblong, 2.5-3 mm long.
