Spikelets 2-2.5 mm. long, pale-green or silvery-green sometimes tinged with purple, somewhat glossy, gaping. Glumes persistent, determining the length of the spikelet, narrowly lanceolate-acute, strongly keeled, flanks smooth or slightly granular, keels scabrid. Lemma 1.5 — 2.25 mm. long, 3-nerved, awnless or with the central nerve excurrent into a short subapical bristle up to 0.5 mm. long, ovate-oblong when expanded, dorsally pilose or pubescent, rarely glabrous, apex denticulate; callus bearded with hairs of varying length.
