Characteristics

Completely prostrate perennial herb, with a single much branched stem 20–30(–50) cm. long, from a fusiform or turnip-shaped woody rootstock 1–5 cm. long and 0·5–2 cm. wide.. Stems slender with shorter hairs and longer yellow or brown bristly hairs, the latter adpressed towards the base of the stem but spreading on the younger parts.. Leaves 1-foliolate; leaflets held closely adpressed to the ground, ovate or almost round, 0·7–7 cm. long, 0·65–5·4 cm. wide, acute to rounded and apiculate at the apex, cordate to amplexicaul with rounded basal lobes, glabrescent to sparsely hairy above, pubescent on the nerves or more rarely densely velvety hairy and with scattered glands beneath, margins ciliate; venation raised beneath; petiole obsolete; petiolule ± 2 mm. long; stipules triangular-lanceolate, 3–5 mm. long, 1·3–2 mm. wide, hairy, veined.. Racemes axillary, the flowering part 1–3 cm. long, 1·3 cm. wide; peduncle (1–)5–14 cm. long, densely covered with short hairs, spreading stiff ferruginous hairs and glands; pedicels 0·5–1 mm. long; bracts deciduous, linear-lanceolate, 5 mm. long, 1 mm. wide.. Calyx densely covered with short white pubescence, stiff spreading ferruginous hairs and glands, 3–5 mm. long; lobes linear-lanceolate, 2–4 times as long as the tube.. Standard cream or dull yellow, often tinged or veined with reddish-brown, obovate or obovate-cuneate, sometimes emarginate, 5·5–7 mm. long, 3·5–4·5 mm. wide, pubescent and with glands in the median area outside; wings pale yellow or cream; keel greenish.. Pod ovate-oblong, 8–10 mm. long, 5·5 mm. wide, apiculate, covered with short pubescence, glands and long ferruginous hairs ±1·5 mm. long.. Seeds black, ellipsoid, longest dimension 2·8 mm., shorter dimension 1·8 mm., 0·8 mm. thick; rim-aril white.
