Spikelets ovate, usually purple tinged, 5–8 mm, florets 2–4(–5); vivipary present or absent; rachilla glabrous or sparsely pilulose to short villous; glumes subequal or equal, lower glume 3.5–4 mm, (1 or) faintly 3-veined, upper glume ca. 4 mm, 3-veined; lemmas 4.5–5 mm, mostly purple, margins membranous, keel villous for 3/4 of length, marginal veins for 2/3, area between veins proximally loosely pilulose or infrequently glabrous, distally smooth to sparsely scabrid; callus webbed, hairs long, dense; palea glabrous or pilulose between keels, keels scabrid, usually medially pilulose to short-villous.
