Caespitose perennials, mostly hummock-forming, often stoloniferous, rarely rhizomatous, resinous or not. Culms strongly branched from lower nodes, usually glabrous. Leaves: sheath much wider than base of blade; orifice bearded or pubescent on margins, rarely glabrous; auricles present or not; ligule a row of hairs or a narrow ciliate membrane; blade rigid, usually tightly folded, rarely some leaves flat, often flexuose when mature, sometimes pseudopetiolate. Inflorescence a panicle or single raceme or spike. Spikelets usually solitary, usually pedicellate, occasionally sessile or subsessile, laterally compressed (often terete when young and rarely remaining so), disarticulating above the glumes and between florets. Florets few to many, bisexual or upper few incomplete, sometimes reduced to awns. Glumes persistent, usually ±equal, entire or variously notched or lobed, sometimes mucronate, rarely awned, separated by a distinct internode. Callus usually short and blunt, sometimes acute to pungent, bearded with a glossy tip. Lemma usually 2-or 3-lobed or-toothed, rarely entire, awnless or mucronate or awned; body at least partly hairy, usually becoming indurated. Palea with 2 scabrous, sometimes winged, keels. Anthers 3, terminally exserted, purple. Grain ellipsoid; hilum short, basal; embryo large.

It is a warm temperate plant.
