Characteristics

Annual or short-lived perennial, with a short erect leading shoot and long trailing much-divided spreading pubescent or pilose branches radiating from the base, up to 6 dm. or more long.. Leaves 3-foliolate; leaflets narrowly to broadly elliptic or oblanceolate to obovate, up to 16–42 mm. long, 5–26 mm. wide, with those of the leading shoot up to 50–68 mm. long and proportionally narrower, glabrous or sparsely pilose above, appressed pilose beneath; petiole up to 12–34 mm. long.. Stipules subulate, 1–4 mm. long.. Racemes subumbelliform, shorter or longer than the opposed leaf, 1–9 cm. long, ± 3–8-flowered; bracts linear, up to 1·5 mm. long; bracteoles inserted at the top of the pedicel, filiform, 0·5–1 mm. long.. Calyx shorter than the corolla, 3·5–4·5(–5) mm. long, pubescent; lobes subulate or narrowly deltoid, ± 1·25–2 times as long as the tube.. Standard suborbicular or obovate, yellow, finely veined reddish-brown and glabrous outside; wings shorter than the keel; keel bent at right-angles in the lower third, with a long tapered untwisted beak, 4·5–6(–7·5) mm. long.. Pod practically sessile, subglobose, 5–6(–7) mm. long, 4–6 mm. across, 4·5–6 mm. in dorsiventral diameter, thick-walled and tardily dehiscent, densely covered with hairs obscuring the fruit-surface, ultimately somewhat glabrescent and sometimes rugulose, but without the vein-network raised, 1–3-seeded.. Seeds sub-orbicular in outline, 3–3·5 mm. across, slightly rugulose, terracotta or pale brown.

Stipules subulate, 1-4 mm long. Racemes leaf-opposed, subumbelliform, shorter or longer than the opposed leaf, 1-9 cm long, ±3-8-flowered; bracts linear, up to 1.5 mm long; bracteoles at the top of the pedicel, filiform, small. Calyx shorter than the keel, 3.5-4.5(-5) mm long, pubescent; lobes subulate or narrowly triangular-acuminate, ±1.25-2 times as long as the tube.
