Inflorescence lanceolate (occasionally linear), 7–25 cm. long, the racemes 1–5 cm. long and densely crowded with appressed spikelets. Spikelets elliptic to subglobose, small, 1.5–2.5(–3) mm. long, ± hispid; lower floret ♂, acute or with a short curved awn up to 5(–15) mm. long; upper lemma 1.5–2.3 mm. long.
