Culms usually glabrous; nodes often swollen, glabrous; fall phase often with reclining culms, ultimately with fascicles of branches with greatly reduced blades and secondary panicles. Cauline sheaths usually glabrous; blades 3-9 mm wide, usually firm, ascending to reflexed, puberulent or glabrous abaxially, glabrous adaxially, with sparse papillose-based cilia at the bases. Primary panicles 4-12 cm long, 1/4 - 1/2 as wide as long, usually narrow, congested. Spikelets 1.3-1.9 mm, ascending to appressed, usually ellipsoid, usually puberulent (rarely glabrous).
