Grass-like, caespitose, multi-stemmed subshrub, erect and 20–50 cm high or sprawling/scrambling ± prostrate. Stems gracile, little-divided, normally terete to subterete or quadrangular. Phyllodes continuous with stems, normally extremely reduced to ± terete, brown appendages 0.5–1.5 mm long, sometimes clearly-developed and superficially resembling stems, 2–33 mm long, 0.3–1 mm wide, erect, quadrangular to terete or ± compressed, subulate, 4-veined with abaxial one the most pronounced, innocuous; gland absent. Inflorescences simple or 1-or 2-headed racemes 5–10 mm long; peduncles 5–15 (–23) mm long, glabrous; heads globular, 15–19-flowered, golden or cream-coloured; bracteoles 0.8–1 (–1.5) × 0.5–0.7 mm. Flowers 5-merous; sepals united, ⅖–½ length of petals; calyx tube glabrous, 1.3–1.5 mm wide at apex, truncate, repand or very shortly dissected into obtuse or broadly triangular, non-thickened lobes; petals glabrous and nerveless. Pods narrowly oblong, prominently rounded over seeds, 20–35 mm long, 4.5–6.5 mm wide, normally shallowly curved, glabrous or sparsely pilose, margins thickened. Seed transverse, 2–2.5 mm long, black, arillate, areole circular to elliptic.
