Superior glume somewhat shorter than the spikelet, oblong-lanceolate, 3-nerved, appressed hairy, hairs fine, smooth, acute, slightly overtopping the glume. Inferior lemma as long as the spikelet, oblong-lanceolate, 5-nerved, nerves equidistant, smooth, appressed hairy, hairs slightly overtopping the lemma.
