Phyllodes erect, straight, terete or quadrangular-terete, (6–) 8–13 cm long, 1–1.2 mm diam., coarsely pungent, rather rigid, minutely sericeous in the shallow longitudinal grooves between nerves, 16-nerved although sometimes only 8 readily visible; nerves closely parallel, slightly raised, subequally prominent, with widest (c. 0.2 mm) on the four slight angles. Inflorescences simple, 1 or 2 per axil; peduncles 0.5–1.5 mm long, densely sericeous; spikes 10–11 mm long, c. 5 mm diam., densely flowered, golden. Flowers 4-merous; sepals ½–¾-united, sparsely puberulous. Pods linear, flat, slightly raised over and slightly constricted between seeds, straight, to 6.5 cm long, 2–2.5 mm wide, chartaceous, sparsely appressed-puberulous. Seeds longitudinal, oblong-elliptic, 3.5–4 mm long, ±shiny, pale brown; funicle/aril a series of loose loops.
