Characteristics

Erect, spreading or trailing subshrub 0.6–4.5 m. long or tall.. Stems glabrescent to densely covered with short tubercular-based hairs.. Leaves 12–32-foliolate; leaflets oblong, obovate-oblong or linear-oblong, 2–10(–15) mm. long, 1–3.5 mm. wide, rounded and mucronulate at the apex, obliquely rounded at the base, glabrous or slightly pubescent beneath, often ciliolate when young; petiole and rhachis together 1–5(–6) cm. long, pubescent; petiolules 0.5 mm. long; stipules ovate to ovate-lanceolate, 0.6–2.5 cm. long, 1.5–3.5 mm. wide, acuminate, obliquely appendaged on one side, leafy, glabrous or pubescent, persistent.. Inflorescences axillary, several–10-flowered, often branched; rhachis 1–9.5 cm. long, sometimes zigzag; peduncle 1–2(–5) cm. long; pedicels 0.3–1.3 cm. long; bracts 1.5–4 mm. long, 2–3-lobed, ± persistent; bracteoles ovate-lanceolate, 2–4 mm. long, 0.5–1 mm. wide, usually ciliolate.. Calyx glabrous or slightly pubescent, 2-lipped, the lips ovate, 4–6 mm. long, 3–4 mm. wide, one 2-toothed, the other 3-toothed.. Standard orange-yellow with reddish veins, violin-shaped, 0.7–1.1 cm. long, 4–7 mm. wide; wings orange-yellow, paler towards the base; keel-petals pale greenish-yellow, not laciniate.. Pods of 2 (rarely 1) articles, joined by a very narrow neck, each rounded-ellipsoid or semicircular, 4–6.5 mm. long, 3–4 mm. wide, compressed or slightly inflated, glabrous, reticulate, sometimes with a slightly granular texture, the margins slightly thickened.. Seeds reddish-brown, oblong-reniform, longest dimension 3.5 mm., shorter dimension 2.3 mm., 1.5 mm. thick; hilum small, elliptic.
