Glumes smooth, swollen and rounded below, narrowed above and tapering to long-acuminate tip, keel scabrid; lower = spikelet, upper c. ¾ length of spikelet. Lemma 0.9-1.2 mm, hyaline, sparsely short-hairy near margins and in upper ⅓; awn 3-4.2 mm, very fine, geniculate, or 0 within the same spikelet. Palea hyaline, glabrous. Anthers 0.6-0.8 mm.
