Spikelets spreading to reflexed, close together to far apart, obovate or oblong, with l:w less than 3, 4–5 mm long, 2–3 mm wide, 6–10-flowered, with (1–) 2–5 loosely overlapping bisexual florets. Glumes 2–3.5 mm long. Basal lemma ovate, with back straight, 3–4.5 mm long, entire, awned, decidedly firmer than the glumes, coriaceous, 3-nerved, scaberulous, glabrous; midnerve scabrous.
