Prostate, intricately branched, often sprawling shrub. Branches puberulous, the hairs normally antrorsely appressed, rarely dividing into a few short, straight, wide-spreading, rigid, ±coarsely pungent lateral branchlets. Stipules 2–3 (–4) mm long, innocuous to slightly pungent. Phyllodes in ±nodose fascicles of 2–5 (–9, single on new shoots, shape and size variable, commonly asymmetrically narrowly oblong-oblanceolate or obovate, (8–) 10–25 mm long, (2–) 3–5 (–6) mm wide, l: w = 3–5 (–6), innocuous, normally shallowly incurved, thin, with fine, appressed hairs on margins and sometimes midrib otherwise glabrous, puncticulate by scattered, small, circular, sessile, brown resinous trichomes; 1-veined. Inflorescences simple; peduncles (7–) 10–30 (–40) mm long, slender, often shallowly curved or wavy when dry; heads globular, 22–25-flowered, yellow; bracteoles 1.5–2 mm long, often slightly exserted in mature buds, the laminae triangular-lanceolate and acuminate. Flowers 5-merous; sepals ±free. Pods tightly and sometimes irregularly spirally coiled, 5–15 mm long (unexpanded length), 3–4 (–5) mm wide, ±veinless. Seeds longitudinal, normally obloid, 3–4 mm long, turgid, normally not mottled; aril white.
