Inflorescences: rachis glabrous; branches 1–7 cm long, far apart, erect or spreading. Spikelets spreading, close together to far apart, ovate, with l:w greater than 3, (5–) 8–15 mm long, 1.3–3 mm wide, 6–8-flowered, with 1–4 loosely overlapping bisexual florets. Glumes: lower glume 2–3.5 mm long; upper glume 3.1–5.5 mm long. Basal lemma lanceolate to ovate, convex in profile on the back or straight, 3.4–6 (–7.5) mm long, entire, awned, decidedly firmer than the glumes, coriaceous, 3–5 (–7)-nerved, scaberulous, glabrous; midnerve scaberulous. Upper bisexual lemmas with longer awns than basal floret. Palea 1/2–2/3 length of lemma body; body smooth or scaberulous, glabrous; keels ciliolate.
