Spikelets usually 1-flowered, sessile, imbricate in 2 rows on one side of the axis, ovate-oblong, much compressed, about 2 mm long, breaking up at maturity above the glumes, purplish or green; glumes more or less persistent, equal or slightly unequal, narrow, pointed, keeled, 1-nerved, 1.5 mm long, membranous; lemma as long as the spikelet, boat-shaped, blunt, keeled, 3-nerved, firm, densely and minutely hairy on the keel; palea as long as the lemma, 2-keeled; anthers 3, up to 1 mm long. Caryopsis tightly enclosed between the hardened lemma and palea.
