Peduncles 4–12 mm long, glabrous or sparsely hairy. Spikes mostly single in axils, 2–4.3 cm long, interrupted, golden. Flowers 5-merous; calyx c. 0.2–0.3 mm long, with free slender glabrous sepals; corolla c. 1–1.2 mm long, dissected to ⅓–½ of length, apically swollen, ± glabrous; ovary glabrous. Pods constricted between and raised over seeds, substraight to curved, openly coiled following dehiscence, 3.5–10 cm long, 1.5–3 mm wide.
