Racemes axillary, sometimes forming a “terminal” corymb, 3–7 cm long, hairy like the stems; peduncles 1.3–2 cm long; pedicels 5–6 mm long, both similarly pubescent; bracts sheathing, 3-fid or 2-fid at the apex, 4–9 × 3–5 mm, elliptic, obscurely ciliolate, very soon deciduous; bracteoles 4.5–6 × 2–2.5 mm, ovate-lanceolate, glabrous or ciliolate, deciduous.
Shrub 1.5–4.5 m tall; bark rough, greyish-brown, some of the stems lenticellate, appearing jointed at the nodes due to the scars formed by the deciduous stipules; young shoots densely covered with glandular tubercular-based hairs.
Standard pale yellow, sometimes veined lilac, or crimson, 10–11 × 7–8 mm, rounded oblong, broadly rounded; wings and keel yellow, the former free, the latter much exceeding the standard.
Fruit of 1–2 articles, if 2 then joined by a narrow neck, each semicircular, 10–20 × 6–10 mm, compressed, glabrous or with one or two obscure hairs on the rounded margin.
Seeds chestnut-coloured, 5 × 3.5–4 × 1.7 mm, oblong-reniform, rather sharply beaked to the outside of the small eccentric hilum.
Calyx reddish, glabrous, 2-lipped; lips 8–9 × 4–5 mm, oblong-lanceolate or oblong-elliptic, one 2-fid, the other 3-fid.
