Plants loosely cespitose, without rhizomes. Innovations extravaginal. Blades lax, flat or convolute; ribs shallow and indistinct; sclerenchyma forming pillars or girders at the major veins. Calluses sometimes wider than long, sometimes narrower, scabrous at the margins; lemmas chartaceous, sometimes minutely bidentate, usually awned, sometimes unawned; ovary apices densely pubescent.
