Phyllodes terete or sub-terete, (15–) 20–60 (–70) mm long, 0.8–1.5 mm diam., apices terminated by a hard, innocuous point, mostly shallowly to strongly incurved, subrigid, ascending to erect, normally glabrous, resinous; finely multi-striate with ±obscure veins. Inflorescences simple; peduncles mostly 8–22 mm long; flowers in globular or obloid heads or cylindrical spikes, 5–22 mm long, light golden. Flowers 5-merous; calyx gamosepalous, shortly dissected into triangular lobes, ½–¾ length of corolla. Pods narrowly oblong to linear, flat, 15–50 (–70) mm long, 2.5–5 mm wide, thinly coriaceous-crustaceous, brown, glabrous, valves deflexed along outer rim to form a narrow, perpendicular edge that is same colour as valve face.
