Spikelets laterally compressed, florets several to many with the uppermost reduced, widely spaced; rachilla scabrid or pubescent, disarticulating below each floret; glumes narrow, very unequal, persistent; lower glume small, sometimes minute, 0–1-veined; upper glume much longer, 1–3-veined; lemmas narrowly lanceolate, membranous becoming firm at maturity, rounded or occasionally keeled, faintly 3–5-veined, back smooth, scabrid or pubescent, margins inrolled over palea, apex narrowed into an awn; awn straight or curved, usually longer than lemma; callus short, glabrous or bearded; palea slightly shorter than lemma, keels ciliolate. Stamens 1–3. Ovary glabrous. Caryopsis narrow, tightly enclosed by lemma and palea; hilum linear.
