Culms (5) 8-20 (25) cm, usually 2-3 times the height of the vegetative shoot leaves, usually glabrous below the inflorescence. Outer vegetative shoot sheaths mostly stramineous; blades smooth or scabrous on the abaxial surfaces, ribs on the adaxial surfaces with hairs shorter than 0.06 mm; abaxial sclerenchyma in 5-7 narrow abaxial strands. Lemmas usually scabrous towards the apices and often along the margins.

Distribution

Wash., Utah, Alaska, Colo., Nev., Oreg., Calif., Alta., B.C., N.W.T., Yukon
