Plants perennial, densely tufted. Culms usually erect. Leaf blade flat or involute. Spike rather lax; rachis tough, glabrous or margin scaberulous. Spikelets 1 per node, with 3–6 florets; rachilla glabrous. Glumes lanceolate, 5–7-veined, glabrous or only midvein sometimes with a few spinules toward apex, apex truncate or obtuse to pointed. Lemma linear-lanceolate, usually 5-veined, glabrous but scabrous, awned or awnless; callus usually obscure; awn divergent at nearly 90° at maturity. Palea usually equaling lemma. x = 7.
