Spikelets elliptic to broadly elliptic, 2.5–3.5 mm. long, glabrous or pubescent, acute to cuspidate, with or without a stipe up to 0.5 mm. long; lower glume 1/3–1/2 the length of the spikelet; upper glume and lower lemma membranous, or rarely the latter coricaceous; upper lemma rugose, subacute to acute.
