Leaves 3-foliolate; leaflets elliptic-lanceolate to elliptic-ovate, mostly 2.5-7 x 1-3.5 cm, glabrous to densely hairy; petioles mostly longer than the leaflets. Stipules linear and caducous or absent. Racemes stoutly pedunculate, many-flowered; bracts narrow or much expanded, caducous. Calyx 1.8-3 cm long, with the upper and lateral lobes joined almost to the tips on either side, ± twice as long as the tube. Standard ovate, lemon-yellow to greenish yellow, sometimes medially pubescent outside; wings half to two-thirds as long as the keel; keel broadly rounded, with a relatively short projecting often greenish or purplish beak, 3.5-4.5(-5.5) cm long. Legume oblong-clavate, narrowed to a 1.5-2.5 cm long stipe, ±7.5-10 cm long, glabrous. Seeds oblique-cordiform, 6-7(-9) mm long, smooth, pale brown.
Woody subshrub, 1-2 m high; twigs glabrous, rounded. Lvs glabrous, 3-foliolate; petiole c. 30-120 mm long; stipules inconspicuous; leaflets broadly elliptic, mucronate or obtuse, 20-70 mm long; petiolules ± equal, c. 2 mm long. Infl. terminal, on a stout peduncle; racemose with numerous fls; pedicels 10-15 mm long; bracts foliaceous, deciduous; bracteoles attached to pedicel, filiform, persistent, 4-6 mm long. Calyx glabrous, the upper and lateral teeth on each side connate to tip or nearly so, and so calyx appearing 3-toothed; calyx teeth much > tube. Standard strongly reflexed, yellowish green, ovate; wings 1/2 as long as keel; keel rounded into a short darkened straight beak, 35-60 mm long. Pod glabrous, cylindric, stipitate, many-seeded, 7-10 cm long; seeds pale brown, 6-7 mm long.
Perennial, bushy, woody herb or shrub, 0.3-2.0(-10.0) m high. Leaflets ± elliptic-ovate, glabrous to densely hairy, 25-70 mm long; petioles mostly longer than leaves. Stipules linear, caducous or absent. Inflorescences stoutly pendunculate, many-flowered racemes. Flowers lemon-to greenish yellow. Calyx with lobes ± twice as long as tube. Petals: wings ± half as long as keel; keel widely rounded with a projecting greenish or purplish beak. Pod 75-100 mm long, oblong-clavate, stipitate, glabrous. Seeds oblique-cordiform, smooth, pale brown.
Standard ovate, lemon-yellow to greenish-yellow, sometimes medially pubescent outside; wings half to two thirds as long as keel; keel 3.5–4.5(5.5) cm long, obliquely ovate-elliptic, with a relatively short, forwardly directed, often greenish or purplish beak.
