Inflorescence: generally digitate; branches 2–30, sometimes in distinct whorls, each raceme- or spike-like branch with 2 rows of overlapping spikelets on 1 side of axis.
Spikelet: laterally compressed; glumes unequal, < florets, 1–3-veined; axis breaking above glumes; lower florets fertile, 1–2, upper florets sterile or staminate, 1–4, < 1/2 lower floret length; fertile floret lemma ovate to lanceolate, back glabrous, midvein hairy, 3-veined, awn 1; palea < lemma, translucent, obscure; anthers 3.
