Plants very loosely mat-forming with tillers widely spaced; innovation buds intravaginal; rhizomes horizontal, underground, long and spreading. Culms 10–15 cm high. Leaves glabrous; blade persistent, expanded. Inflorescences hemispherical, stiffly erect, open with patent spikelets, 2.5–5 cm long; branches glabrous, rarely finely scaberulous below spikelets. Spikelets 5.5–7 mm long, with 3–4 florets. Glumes shorter than spikelet; lower glume 3.8–5 mm long. Lemma: body 1.6–2.2 mm long, dull, with villous tufts; lobes shorter than body, entirely fused to awn; awn 2.5–3.2 mm long, with column straight; indumentum in upper row only marginal tufts; indumentum in lower row only marginal tufts or absent, not reaching upper row. Palea 3.2–3.4 mm long, narrow, 3–5 times as long as wide. Caryopsis 1.2–1.5 mm long.
