Spikelets often purplish, circular in outline, 2.5–3.5 mm, acute; upper glume ovate, 3-veined, with stiff marginal wings ca. 1 mm wide, wings lacerate, wing margin ciliate with short stout hairs; lower lemma similar to upper glume but wing less developed; upper lemma ovate-elliptic, slightly shorter than spikelet, smooth, shining.
