Peduncles 4–12 (–15) mm long. Spikes 1–3 in upper axils of phyllodes, 10–50 mm long, usually bright to golden yellow. Flowers 5-merous; calyx 0.75–1 mm long, dissected to ⅔ of length or more, membranous; corolla 1–1.5 mm long, dissected ⅓–½ of length; petals with faint midrib. Pods very narrowly oblanceolate, tapering gradually at base, slightly raised over seeds, straight or very slightly curved, 2.6–5 cm long, with ±hooked apex, woody, brown, with conspicuous diagonal nerves and some anastomosing, glabrous; margins thickened; valves recurved following dehiscence.
