General Description
Bunchgrass. Stems 3–9 dm. Leaves: blades 1–3 mm wide, flat to rolled, sheath and collar often hairless. Inflorescence 4–20 cm long, rachis continuous, internodes >10 mm long. Spikelets 10–15(–26) mm long, appressed to the main rachis, florets mostly 3 to 7 per spikelet, glumes shorter than florets, awnless or short-awned. Lemmas hairless to inconspicuously hairy, with a divergent awn up to 2 cm long, rarely awnless (Lavin in
