Prostrate annual up to 0.8 m wide. Branches sparsely leafy, densely silky. Leaves invariably 5-foliolate, (6-)10-18(-24) mm long; petiole ± as long as the terminal leaflet or longer; leaflets relatively small, broadly obovate, (3-)5-8(-10) mm long, (2-)3-5(-7) mm wide, base cuneate, apex truncate to emarginate, densely silky on both surfaces. Stipules single at each node, lanceolate to broadly ovate, 3-4 mm long, 2-3 mm wide, densely silky on both surfaces. Inflorescences in terminal heads, the heads somewhat flattened, 4-8-flowered; peduncle variable in length, 5-50 mm long; bracts large, broadly obovate, ±4 x ±4 mm; bracteoles absent. Flowers relatively small, 12-14 mm long, yellow; pedicel absent. Calyx subequally lobed but with the lower lobe slightly narrower than the upper four lobes, the sinuses of equal depth; lobes broadly triangular, acute. Standard oblong, as long as the keel; claw 4-5 mm long; lamina ±8 mm long, 5-6 mm wide, without lobes or callosities, glabrous but with a few hairs dorsally along the middle. Wing petals oblong, ± as long as the keel, glabrous; auricle small, ±1 mm long; apex obtuse; sculpturing in 4-5 rows of intercostal lunae, fading into transcostal lamellae towards the auricle. Keel petals obovate-oblong, only slightly auriculate; claw 5 mm long; lamina 9 mm long, 5 mm wide, glabrous; apex rounded. Androecium long and narrow; anthers dimorphic; basifixed anthers oblong, slightly longer than the small ovoid dorsifixed anthers; carinal anther similar to dorsifixed anthers. Gynoecium sessile; pistil very small, ovoid-oblong, pubescent, with 5-12 ovules; style long and slender. Pods and seeds unknown.
