Plants cespitose, with caudices. Basal rosettes well-differentiated. Culms 5-60 cm tall, 0.2-0.8 (1.6) mm thick, erect or reclining, sometimes geniculate at the lower nodes, glabrous or sparsely pubescent near the bases; fall phase branching from the lower and midculm nodes. Cauline leaves 3-9; sheaths glabrous or sparsely pilose, usually ciliate; ligules 0.2-1.8 mm, of hairs; blades usually 2-5 cm, sometimes with prominent white, cartilaginous margins.
