Inflorescence spikelike, 2–7 × 0.3–0.5 cm; racemes solitary, rather spaced, strictly distichous, spikelets also distichous on the raceme rachis. Spikelets 2–4 mm, florets (2–)4–8; glumes ovate, laxly ciliate or nearly glabrous; lower glume 1–2 mm; upper glume 1.5–2.5 mm; lemmas ovate, lowest 1.5–3 mm, 5–9-veined, margins membranous and ciliate, apex cuspidate; palea equal to lemma, keels ciliolate, apex truncate or emarginate. Anthers ca. 1.5 mm. Fl. and fr. May–Aug.
