Racemes axillary from upper leaves, overtopping the terminal bud and appearing as a large branched terminal inflorescence, 7–20 cm long, densely pubescent with hairs similar to those on the stems or glabrescent; peduncles 3–4 cm long; pedicels 5–15 mm long, both similarly pubescent; bracts 14 × 7 mm, oblong-elliptic, acuminate, cucullate and clasping, glabrous, very soon deciduous; bracteoles 7–10 × 5 mm, elliptic, cucullate and clasping, glabrous, soon deciduous.
Fruit of (4)5–8 articles joined by narrow necks, each article semicircular or elliptic, 6–7 × 5–6 mm, compressed, glabrous or sometimes with very scattered ciliae when young, rarely persistently bristly ciliate, smooth.
Standard bright yellow or orange, flushed crimson or veined brown outside, 1.7–2.2 × 1.4–1.8 cm, almost round or broadly elliptic, rounded or emarginate; wings and keel yellow, the former free.
Stems densely covered with short glandular tubercular-based hairs or glabrous; older stems appearing jointed at the nodes due to the scars formed by the deciduous stipules.
Calyx red, glabrous, 2-lipped; lips 13–18 × 5–6 mm, oblong, both entire or one with slight trace of 3-lobing.
Shrub or small tree 1.2–6 m tall; bark brown, smooth with conspicuous white lenticels.
Seeds yellow-brown, 4–5 × 3 × 2–2.2 mm, oblong-ellipsoid; hilum small, eccentric.
