Description Loosely cespitose from stout, matted, somewhat elongate root- stocks ; culms phyllopodic, 6-8 dm. high, slender, short-pubescent, brownish-tinged at the base, the old leaves conspicuous; leaves with well-developed blades 5-10 to a fertile culm, clustered on the lower half, their blades 2-3 dm. long, 2-3 mm. wide, stiff, flat with revolute margins, densely villous beneath, sparsely pilose above, attenuate, the sheaths villous dorsally, yellowish-brown ventrally, concave at the mouth, the ligule short ; terminal spike staminate, short-peduncled to subsessile, 15-25 mm. long, 2-3 mm. wide; lateral spikes about 4, the 2 upper approximate, the others more
or less separate, pistillate, with 10-25 perigynia, 8-15 mm. long, 4-6 mm. wide; lower bracts leaf-like, the upper reduced; scales acute to mucronate, sparsely pilose, hyaline with three-nerved, greenish or yellowish center ; perigynia obovoid, sharply trigonous, 3.5 mm. long, 1.75 mm. wide, ascending, membranaceous, light- green, short-pilose, three-nerved on each face, the beak flattened- subconic, 0.75 mm long, bidentate, the teeth hyaline; achenes trigonous with concave sides, 2.25 x 1.5 mm., closely enveloped, apiculate, jointed with the short style.
