Diffuse, intricately and openly branched, low-spreading shrub 0.3–1 (–1.5) m tall, sometimes semi-prostrate, oldest plants somewhat craggy by persistent, short lateral branches which are denuded of phyllodes. Branchlets lenticellular, glabrous, resinous. Stipules persistent, 0.5–1 mm long, erect, often enveloped in resin. Phyllodes asymmetrically elliptic to obtriangular, broadest at or above middle, lower margin ±shallowly convex or straight, the upper margin markedly convex and sometimes angled at the gland, 3–6 (–7) mm long, 2–3 mm wide, l:w ratio = 1–1.6, shortly acuminate and terminated by a distinct cusp 0.5–1 mm long, glabrous; midrib ±central, sometimes with an indistinct second nerve; gland single, at or above centre of upper margin. Inflorescences simple, 1 per axil; peduncles 6–8 mm long, red (fresh), glabrous, base ebracteate; heads globular, densely 40–50-flowered, golden. Flowers 5-merous; sepals free, linear-spathulate. Pods linear to narrowly oblong, flat but shallowly rounded over seeds, 10–40 mm long, 3–4 mm wide, firmly chartaceous, glabrous. Seeds not seen but funicle probably exarillate.
