Characteristics

Prostrate perennial, with many well-branched radiating stems up to 6 dm. long.. Stems angular, thinly appressed puberulous.. Leaves mostly well spaced, 3–foliolate; leaflets oblanceolate, oblanceolate-elliptic or obovate, up to 15–32 mm. long, 6–15 mm. wide, glabrous above, appressed puberulous beneath; petiole up to 5–15 mm. long.. Stipules shortly stalked, linear to lanceolate-falcate, up to 5–8 mm. long, 1–2 mm. wide, acuminate, markedly unequal-sided.. Racemes lax, up to 7 cm. long, ± 3–8-flowered; bracts subulate or filiform, up to 3 mm. long, caducous; bracteoles inserted on the short ascending pedicel, filiform, up to 2–3 mm. long, caducous.. Calyx 8–11 (–13) mm. long, appressed puberulous; upper lobes narrowly attenuate-triangular, longer than the tube.. Standard suborbicular, yellow, often tinged reddish outside, fading orange, glabrous outside; wings broadly oblong, longer than the keel; keel abruptly rounded, tapered gradually into a very blunt straight untwisted beak, 11–13 mm. long, densely white lanate-pubescent on the lateral surfaces towards the upper margin.. Pod subsessile, cylindrical, 20–27 mm. long, 8–10 mm. across, subglabrous, sometimes with a few scattered hairs or pubescent along the upper side, 16–22-seeded.. Seeds oblong-reniform, 3–3·5 mm. long, with a small white aril much shorter than the hilar sinus, finely granulate or smooth, bright orange or red, rarely pale yellow.
