Vernal phase yellowish-green; culms erect, 35-50 cm. high, glabrous, the nodes sparsely villous; leaf-sheaths glabrous, or the lowermost sparingly pubescent, ciliate on the margin; blades ascending, flat, 8-12 cm. long, 9-12 mm. wide, glabrous, ciliate at the rounded base; panicles few-flowered, 7-9 cm. long, half as wide or less, with a few ascending branches; spikelets mostly long-pediceled, 2.9-3 mm. long, 1.2 mm. wide, elliptic, sparsely pubescent; first glume about one third the length of the spikelet ; second glume and sterile lemma equaling the fruit at maturity; fruit 2.3 mm. long,. 1.1 mm. wide, elliptic, subacute.
Autumnal phase sparingly branching from the middle nodes, the branches about as long as the internodes, erect; blades not greatly reduced; panicles narrow, partly included.

Vernal phase bluishgreen; culms erect or ascending, 30-50 cm. high, glabrous, or the lowermost portion puberulent; nodes sparsely bearded or glabrous; leaf -sheaths glabrous or the lower sparsely villous especially above the nodes; blades stiffly ascending, or somewhat spreading, elongate, 8-15 cm. long, 3-8 mm. wide, the uppermost usually longest, narrowed toward the base, there usually ciliate with a few stiff hairs; panicles ovoid, 5-8 cm. long, about two thirds as wide, the branches ascending, bearing few long-pediceled spikelets, these 2.3-2.8 mm. long, 1.1—1.2 mm. wide, oblong-elliptic, sparsely pubescent or rarely glabrous; first glume about one third the length of the spikelet, subacute; second glume and sterile lemma equal, covering the fruit at maturity; fruit 2 mm. long, 1.1 mm. wide, elliptic, subacute.
Autumnal phase erect, branching from the middle nodes, forming a loose, bushy crown of stiffly ascending blades not much reduced and overtopping the narrow, few-flowered panicles.
Type locality: Bronx Park, New York. Distribution: Connecticut to Georgia and Missouri.
