Inflorescences axillary or terminal panicles, much branched, up to 30 cm long or more, peduncle 0.5–5.5 cm long, sericeous; primary or secondary lateral branches 1.7–25 cm long, sericeous. Bracts subtending lateral branches ovate to triangular, 1.5–1.7 by 0.5–0.6 mm, caducous, outside sericeous, inside glabrous; bracts subtending flowers narrowly ovate, 1–1.5 by 0.3–0.6 mm, caducous, outside sericeous, inside glabrous. Pedicels 1–2 mm long, sericeous. Bracteoles at the top of the pedicels, narrowly triangular to acicular, 0.9–1.1 by 0.1–0.2 mm, outside sericeous, inside glabrous, usually caducous. Calyx reddish to pinkish-green or pale yellowish, cup-shaped, 3.7–4.2 mm high, outside sericeous, inside glabrous, upper lip shortly triangular, 0.1–0.25 by 2–2.5 mm, sometimes indistinct, lateral lobes shortly and broadly triangular, 0.2–0.3 by 3–3.3 mm, sometimes indistinct, lower lobe shortly triangular, 0.1–0.2 by 1.5–2 mm. Corolla white or creamy, usually with green and dark brown spots scattered along the margin of the petals. Standard: claw 1–1.7 mm long; blade obovate or orbicular, 4.5–6 by 4.5–5.5 mm, apex slightly emarginate, glabrous, with basal callosities and thickened inside in the middle of the petal. Wings: claw 1.5–2 mm long; blade elliptic, 6.3– 6.7 by 3.5–3.7 mm, apex rounded, both sides glabrous, upper auricle0.8–1 mm, lower auricle indistinct, lateral pocket indistinct. Keel petals: claw 3–3.3 mm long; blade boat-shaped, slightly oblique, 6–6.5 by 2.8–3.2 mm, apex rounded, glabrous, upper auricle 0.5–0.7 mm, lateral pocket 1.5–2 mm long. Stamens diadelphous, 7.5–8 mm long, free part 3.5–4 mm long, in two lengths, longer ones alternating with shorter ones, hairy especially at the upper part near the anthers; anthers 0.6–0.8 by 0.4–0.5mm, hairy. Disc 9 or 10 glands, 0.3–0.5mmhigh, hairy. Ovary 5–6 mm long, stipe indistinct, sericeous; ovules 3–6; style 4.5–5 mm long, sericeous throughout. Pods strap-like, flat, 5–15 by 2.5–3.8 cm, glabrescent, not sinuate, with wings along both sutures, upper wing 3–8 mm wide, lower wing 3–7 mm wide; seed chamber absent. Seeds 1–4 per pod, narrowly bean-shaped, 11–22 by 9–13 by 1.5–2.5 mm; hilum eccentric, ca. 2 mm long.
