 high; leaves Hat, sliortor than the culm; spike T long or less, densely cylin- 

 drical, very rarely with a rudimentary second spike at its base; jjcrigynium

 Mountains of N. New Eug. ; Drummond's Island, L. Huron. (Norway.) 



* 7. — -1-2. Montana'. 

 ■*^ Some or all of the culms lonfjer than the leaves {or in the tijpe ofn. Sb/re- 



qiientlij shorter). 



= Staminate spike minute, wholly or partial I >/ concealed in the head; leaves 



ahca//s very narrow ; radical spikes often present. 



85. C. deflexa Ilornem. Diffuse and low, tufted ; culms 1 - G' high, 

 setaceous, more or less curved or spreading, little exceeding or shorter than 

 the leaves ; staminate spike exceedingly minute and nearly always entirely in- 

 visible in the head; pistillate spikes 2-3, 2 - .5-flowered, green, or green and 

 brown, all aggregated into a head, the lowest one always more or less short- 

 peduncled and subtended by a leafy bract ^' long or less ; radical spikes few ; 

 porigynium very small and much contracted below, sparsely hairy or nearly 

 smooth, the beak iiat and very short, mostly longer than the acutish scale. 

 (C. NovaB-Angliic, la.st ed., mostly.) — High mountains of N. II. and Vt. 



Var. Deanei, Bailey. Taller and lax, the culms 6-12' high and some 

 or all prominently longer than the longer and loose leaves; staminate spike 

 umch larger (2 -3" long), erect or oblique, sessile ; pistillate spikes larger (4 - 

 8-flowered), less aggregated or the lowest usually separated, though rarely more 

 than \' apart ; radical spikes usually numerous ; bract mostly longer. — Swales 

 or dryish places, high or subalpine regions, Mt. Desert, Maine {Rand) ; Essex, 

 Mass. ; N. H., Vt., and N. Y. ; scarce. In aspect like n. 86. 



Var. m6dia, Bailey. Rather stiff, 4-12' high, in dense tufts ; most of the 

 spikes equalling or exceeding the leaves, the staminate prominent, erect (3 - 

 5" long), sessile or very short-peduncled ; pistillate spikes 2-3, all scattered, 

 the uppermost at or near the base 'of the staminate spike, the lowest usually 

 very prominently pedunded and subtended by a conspicuous bract which sur- 

 passes the culm, all rather compactly 3 - 8-tlowered, green, or brown and green ; 

 radical spikes several ; perigynium larger, mucli like that of short-beaked forms 

 of n. 90. — Keweenaw Co., Midi. {Farwell); also far westward. 



86. C. varia, Muhl. Erect, mostly strict, 6-15' high, tufted and some- 

 what stoloniferous; culms varial)le in length, often twice longer than the 

 leaves; .staminate spike 3" long or less; pistillate spikes closely aggregated, 

 or rarely somewhat loosely disposed but never scattered, all strictly sessile, 

 green ; radical spikes none ; lower bract usually j)resent ; perigynium longer- 

 pointed than in the last, about the length of the sharp scale. (C. Emmonsii, 

 Dewey.) — Banks and dry woods; frequent. — In var. colouXta, Bailey, the
