Perennial herb, with annual branches from woody base, up to 400 mm high; procumbent. Leaves trifoliolate, but with basal leaves usually unifoliolate, especially in resprouting specimens, alternate; leaflets small, < 10 mm wide. Flowers: bracteoles 0; keel acute, petals < 9 mm long, corolla yellow; Jan.-Dec. Pods linear-oblong, much longer than calyx, slightly tapered towards apex, strigose-pubescent, (12)15-20 x 4.0-4.5 mm, 10-20-seeded.
Prostrate or procumbent perennials. Leaves densely strigillose, trifoliolate, basal ones unifoliolate. Leaflets small, < 6 mm wide. Inflorescences usually 1-flowered; peduncles short or absent. Flowers small, < 8 mm long; yellow or partly white, often cleistogamous. Calyx subequally lobed, upper two lobes wider than lateral ones. Petals: standard ovate, not panduriform. Flowering time Oct.-Apr. Pod oblong, slightly inflated.
Leaves mostly 3-foliolate, lower ones sometimes 1-foliolate; leaflets 10–25 × 2–5 mm, mostly linear-elliptic to oblanceolate, obtuse or rounded to a mucronate tip, strigulose-pubescent on both surfaces; petiole shorter than the leaflets; stipules single at a node, resembling small leaflets.
Standard yellow, fading reddish, ± as long as the other petals, narrowly ovate-elliptic above a well developed basally dilated claw, pubescent along the midvein outside; keel 6–7 mm long, oblong-falcate, with a small pointed beak, glabrous.
Stems numerous from a stout branched perennial rootstock, decumbent to shortly ascending, resprouting after burning, up to 10–50 cm long, densely silvery strigulose or strigulose-pubescent with slightly biramous hairs.
Flowers leaf-opposed, solitary or subumbellately 2–5; peduncle 0–16 mm long; bracts 2–3 mm long, linear to linear-oblanceolate; pedicel 3–5 mm long; bracteoles absent.
Calyx 5–6 mm long, densely strigulose-pubescent; upper and lateral lobes joined at nearly the same level, narrowly triangular-lanceolate, c. 3 mm long.
Pods (12)15–20 × 4–4.5 mm, linear-oblong, slightly tapered towards the apex, strigose-pubescent, 10–20-seeded.
Seeds c. 2 mm long, rounded, slightly oblique-cordiform, matt, pale brown or mottled.
