63. C. palléscens, L. Slender, erect, 4´–2° high, tufted; leaves narrow, flat, the lower slightly pubescent, particularly on the sheaths; spikes 2–4, ½´ long or less, densely flowered, all but the upper one very shortly peduncled, erect or spreading; perigynium globular-oblong, thin and very nearly nerveless, about the length of the cuspidate scale.—Glades and meadows, N. Eng. to Penn., Wisc. and L. Superior; rare westward. (Eu.)
[++][++] Perigynium very stout-beaked.
64. C. Torrèyi, Tuckerm. Stiff, 1–1½° high; culm and leaves thinly pubescent; spikes all sessile, very short; perigynium obovate, very strongly many-nerved, retuse, the beak short and straight, equalling or exceeding the mostly cuspidate scale.—Supposed to have been collected, a half-century ago, in N. Y. by Torrey, and in Penn. by Schweinitz. It occurs in the Rocky Mountain region, and high northward.
[*] 6. Dactylostàchyæ.—[+] 1. Oligocárpæ.
[++] Sheaths smooth.
65. C. conoídea, Schkuhr. Slender but strict, 1–1½° high; staminate spike long-peduncled or rarely nearly sessile; spikes 2–3, scattered, short-stalked or the upper one sessile (the lowest frequently very long-stalked), oblong (rarely 1´ long) and rather loosely flowered, erect; perigynium oblong-conical, impressed-nerved, gradually narrowed to a point, the orifice entire; scale loosely spreading and rough-awned, equalling or exceeding the perigynium.—Moist grassy places, N. Eng. to Ill., and southward; rare westward.
66. C. oligocárpa, Schkuhr. Diffuse, 10–18´ high; bracts flat and spreading; staminate spike sessile or stalked; spikes 2–4, scattered, stalked or the uppermost sessile, loosely 2–8-flowered, erect; perigynium small, hard, finely impressed-nerved, abruptly contracted into a conspicuous mostly oblique beak, the orifice entire; scale very loosely spreading and rough-awned, longer than the perigynium.—Dry woods and copses, W. New Eng. to Mo., and southward; rare westward. Often confounded with small forms of n. 58.
[++][++] Sheaths pubescent.
67. C. Hitchcockiàna, Dewey. Erect, 1½–2° high; spikes 2–4, all more or less peduncled, very loosely few-flowered, erect; perigynium triangular-ovate, many-striate, the strong beak prominently oblique, shorter than the rough-awned scale.—Rich woods, W. New Eng. to Ill., and southward to Penn. and Ky.; frequent.
