Perennials, caespitose, bisexual. Leaves: ligule an unfringed membrane, long, becoming laciniate, cartilaginous, often striate-veined; blade linear-lanceolate, long-acuminate. Inflorescences paniculate, open, broadly pyramidal. Spikelets long-pedicellate, laterally compressed, disarticulating above glumes and between florets, with 3–5 (–6) bisexual florets; rachilla hairy, extension with incomplete florets. Glumes 2, subequal to unequal, shorter than spikelet, awnless, keeled, scabrid on keel; lower glume (1–) 3-nerved; upper glume 3 (–5)-nerved. Callus short. Lemma entire or shortly 2-lobed, 1-awned, decidedly firmer than glumes, thinly cartilaginous, slightly keeled, 5 (–7)-nerved; nerves raised, scaberulous. Palea entire, pointed but easily splitting, textured like lemma. Stamens 3. Ovary with minute, stiff hairs at apex. Grain slightly ventrally compressed; hilum short to long-linear, narrowly elliptic, 0.5–0.8 mm long; pericarp loosely adherent, readily removable.
