Information Herbs with slender straggling or trailing stems; leaflets mostly pointed, drying greenish; petioles mostly not exceeding 3 mm in length, often scarcely longer than the stipules.

Information Shrubby; leaflets mostly rounded at the apex, often drying blackish; petioles mostly 3–16 mm long, much exceeding the stipules.

Information Shrubby, up to 1–2 m tall, or a slender-stemmed straggling or trailing perennial herb; branches variously pubescent. Leaves 3-foliolate; leaflets 1–4 × 0.3–1.8 cm, narrowly elliptic-oblong to elliptic, oblanceolate or obovate, sometimes slightly inrolled at the margins, subglabrous to pubescent beneath; petiole 0.5–16 mm long; stipules 1–4 mm long, subulate to triangular-lanceolate, recurved. Racemes on main and usually numerous relatively short lateral branches (which often bear smaller leaves), few-flowered or the flowers solitary; bracts up to 2.5 mm long, linear to linear-lanceolate; bracteoles inserted on the pedicel, small and filiform. Calyx 7–9(11) mm long, glabrous to pubescent; lobes narrowly attenuate-triangular, ± twice as long as the tube. Standard subcircular, yellow, sometimes with darker lines or tinged reddish, glabrous outside except sometimes along the midvein; wings longer than the keel; keel 7–10 mm long, rather strongly rounded and crested behind the short beak. Pod 2–3 cm long, shortly stipitate, subcylindrical, pubescent, 8–12-seeded. Seeds c. 3.5 mm long, oblique-cordiform, smooth, ochre.

Information Shrubby or suffrutescent, up to 90 cm tall; branches densely spreading hairy. Leaves closely arranged, subsessile, 3-foliolate; leaflets mostly 7–15 × 1–3 mm, linear to narrowly oblong-elliptic, with conspicuous recurved apiculum and inrolled margins, thinly hairy; stipules 1–1.5 mm long, subulate-triangular. Flowers solitary or in pairs; bracts 2–3 mm long, linear; bracteoles inserted on the pedicel, small. Calyx 7–10 mm long, rather densely and coarsely pubescent; lobes attenuate-triangular, up to twice as long as the tube. Standard subcircular or oblate, yellow, sometimes tinged reddish, pubescent at least medially and apically outside; wings exceeding the keel; keel strongly rounded, crested behind the short beak, 8–9 mm long. Pod 2–2.4 cm long, subsessile, oblong-fusiform, densely pubescent, 8–12-seeded. Mature seeds not seen.
