Loosely tufted perennial (perhaps annual in some conditions), culms erect, branched or simple, to c. 80 cm high; leaves mostly cauline, sheaths smooth and glabrous; blade flat, folded or inrolled, to 18 cm long and 2 mm wide when flattened, glabrous below (abaxially), shortly hispid above; ligule densely ciliate, c. 0.3 mm long. Inflorescence a slender panicle, to c. 15 cm long; glumes initially purplish, subequal, usually the upper slightly (to c. 1 mm) longer than the lower, narrowly acuminate or sometimes obtuse and shortly mucronate, 5–9 mm long, the lower glume usually persisting; lemma involute, narrow-cylindric, 5.5–7.5 mm long, glabrous except for short, white callus hairs, surface smooth except for tuberculate margins of at least the apical half of the ventral groove, pale or purplish with darker mottling; awn branches 10–18 mm long, the lateral pair shorter by 1–2 mm than the central one. Flowers through the year following rains.

Gold, MuF, VRiv, Wim. All mainland States. Scattered but rare in northern Victoria (e.g. Charlton, Shepparton, Bendigo areas), usually on light soils in plains woodland communities.

Very close to Aristida calycina var. praealta which also has the lemma groove with tuberculate margins. It differs in its slightly smaller florets.
