Spikelets pedicellate, to 1.4 mm long; pedicel to 0.8 mm long. Glumes: lower glume ovate (strongly convex on back), to 0.7 mm long, acute, 1-nerved; upper glume lanceolate, ±equalling spikelet, to 1.4 mm long. Lemma ovate (broader than upper glume), 1.1–1.4 mm long, obtuse, 1-nerved. Palea subequal to lemma, emarginate into 2 subacute parts. Anthers 3, to 0.2 mm long.
