Plants cespitose. Basal rosettes somewhat differentiated. Culms 20-60 cm, weakly ascending, glabrous; fall phase rarely branching from near the base. Cauline leaves 3-4; sheaths sparsely pilose or glabrous; ligules membranous, ciliate; blades mostly basal, flat to stiffly involute, ascending to erect, uppermost blades much reduced. Primary panicles long-exserted, with few spikelets. Spikelets 2.4-3.2 mm, narrowly ellipsoid to ovoid, glabrous. Upper florets acute.
