Phyllodes mostly very narrowly elliptic, mostly shallowly to markedly falcate, flat, (6–) 10–16 (–23) cm long, (6–) 10–18 (–32) mm wide, coriaceous, glabrous, with 3–6 ±prominent main veins continuous to base; minor veins (4–) 5–10 per mm, parallel, not anastomosing; gland inconspicuous, basal. Spikes (2–) 3–6.2 cm long, golden. Flowers 5-merous; calyx cupular, 0.4–0.8 mm long, dissected for ¼ of its length; lower half villous; with red-brown or black glandular hairs in upper half; corolla 1.5–2.1 mm long, dissected for ½ its length, glabrous or with few hairs; ovary densely pubescent. Pods linear, slightly moniliform, (3–) 5–11 (–15) cm long, ±woody to coriaceous, scurfy, hairy near base.
