Plants loosely cespitose, without rhizomes. Innovations extravaginal. Blades lax, flat or convolute; ribs shallow and indistinct; sclerenchyma girders present at the major veins. Calluses wider than long, scabrous at the margins; lemmas stiffly chartaceous, entire, unawned; ovary apices densely pubescent.

Discussion
