Plants forming ringed hummocks to 2 m wide, stoloniferous, with prop roots, highly resinous on leaves and inflorescences. Flowering culms to 1.5 m high. Leaves: lower sheaths flat, fan-shaped, overlapping, many-nerved, ciliate on margins or glabrous; orifice pubescent or bearded with hairs to 6 mm long and with hairs extending along collar on a ridge; blade curved or flexuose, folded or flat (often with age), to 25 cm long, to 2.5 mm wide, not pseudopetiolate, prickly on margins. Panicles ovate to lanceolate, open or rather dense, 5–18 cm long, 4–9 cm wide, with prominent pulvini; axis angular, ribbed, scabrid-pubescent; branches simple or sparsely divided, naked near base, compressed; primary branches 5–6 cm long; secondary branches c. 1 cm long. Spikelets linear to ovate, inflated or slightly compressed laterally, 5–20 mm long, 3–8 mm wide, closely 4–11-flowered; pedicel 5–10 mm long; rachilla flat. Glumes ±equal, broadly ovate or oblong-elliptic, (3–) 6–8 mm long, entire or notched, obtuse, cartilaginous, rounded on back or obtusely carinate, 3 (5–7)-nerved, glabrous or partly pubescent, purplish or straw-coloured. Callus obtuse, glabrous or partly bearded. Basal lemma broadly ovate-elliptic to ±orbicular, 3–6 mm long, hairy in lower part especially on margins and midnerve; body indurated, often yellowish; margins scarious to cartilaginous; lobes ±equal or laterals shorter and wider, less than half total lemma length, flat and triangular with nerves in 3 groups of 2 or 3. Palea almost as long as lemma, narrowly oblong-lanceolate, often beaked, cartilaginous to indurated (thinner towards apex); body glabrous or sparsely hairy near base; keels narrowly winged; flaps hyaline. Anthers 2–3 mm long.
Growsin deep or shallow sandy-clay-loam soils on tablelands, hillslopes, plains,dunes, ridges, and disturbed sites.
