Plants 0.3 to c. 1 m tall. Culm nodes 2–4, exserted, glabrous, thickened. Leaves: sheaths tight, pubescent or glabrous; ligule 1–2.5 mm long, truncate to broadly ovate, ciliate; auricles glabrous or with a few short hairs; blade loosely rolled, 1.5–2 mm wide, smooth, glabrous, scabrous or pubescent on abaxial surface. Inflorescence 20–35 cm long, 2–3 cm wide (excluding awns), open, sparse; spikelets scarcely gaping. Glumes subequal, 14–18 mm long, long-acute to acuminate. Callus 2.5–3 mm long, straight, with hairs similar to those of lemma. Lemma 7–8 mm long, granular, dark brown at maturity, with hairs sparsest at apex, densest at margins; coma absent; lobes c. 0.1–0.2 mm long; awn 70–100 mm long, robust, with column 9–13 mm long, long-pubescent with spreading hairs, and bristle very strongly falcate, scabrous, paler than column.
