Culms 20-60 cm, usually slender, erect; nodes usually glabrous, lowermost nodes sometimes sparsely bearded with soft, retrorse hairs; internodes terete, green to purplish, glabrous; fall phase branching freely from the midculm nodes, producing dense clusters of reduced, flat to involute blades and reduced secondary panicles. Cauline sheaths usually glabrous, lowermost sheaths sometimes sparsely pubescent, margins glabrous or short-ciliate; blades usually 3.5-9 cm long, usually 5-7 mm wide (seldom wider), usually spreading, narrowly lanceolate, glabrous on both surfaces, bases constricted. Primary panicles well-exserted; branches few, flexuous, with fewer spikelets than all the other subspecies apart from subsp. lucidum. Spikelets 1.8-2.3 mm, ellipsoid, usually glabrous, rarely purplish at the base; upper florets 1.7-2 mm long, 0.7-1.0 mm wide. 2n = 18.
