Vernal phase dull-green; culms usually in* dense tufts, erect, 10-25 cm. high, copiously papillose-hirsute, as are the rather loose, usually overlapping leaf-sheaths; ligule about 1 mm. long; blades firm, erect or ascending, 5-8 cm. long, 3-6 mm. wide, broadest toward the base (this scarcely wider than the wide sheath), commonly involute-acuminate, long-hirsute on both surfaces; panicles finally exserted, often equaled or exceeded by the upper blades, 2-5 cm. long, about half as wide, or sometimes more expanded at anthesis, rather densely flowered; spikelets 2.7-3 mm. long, 1.5 mm. wide, obovate-elliptic, papillose-pubescent; first glume about one third as long as the spikelet, pointed or obtuse; second glume slightly shorter than the fruit and sterile lemma; fruit 2.4^2.5 mm. long, 1.3-1.4 mm. wide, elliptic.
Autumnal phase branching from all the nodes, forming bushy tufts with rigid, erect blades much overtopping the reduced panicles ; branches appearing early, usually before the maturity of the primary panicles; secondary spikelets usually more turgid than those of the primary panicles.
Typb locality: Nebraska. Distribution: Manitoba to Iowa and Kansas.
