 smooth, shorter than the very narrow stiff leaves : staminate spike one, 

 usually more or less peduncled : pistillate spikes one to three, a half- 

 inch long or less, sessile or very nearly so in the axils of sheathless 

 bracts (rarely a short sheath in the lower bract of large specimens) : 

 perigynia ovate, more or less nerved, usually exceeding the obtuse or 

 barely pointed scale. — Cumberland House and Hudson's Bay, Herb. ;

 Culm two feet or more high, sharjily angled, smooth or rough just 

 below the spikes ; leaves ordinary, narrow and flat : spikes all droop- 

 ing on filiform peduncles from one to three inches long, a half-inch or 

 more of the apex staminate, rather lax-flowered, especially at the base, 

 very dark brown or black, two inches or less in height, and varying 

 from broadly oblong (one inch by one third inch) to narrowly cylin- 

 drical (two inches by one fifth inch) : staminate spikes two or three, 

 the lateral ones usually peduncled : perigynium oval or oboval, yellow- 

 ish, lightly nerved, contracted into a very short and entire beak, twice 

 or thrice shorter than the lanceolate dark brown or black scale.

Larger and much stouter than the last, two to five feet high, the 

 culm very sharply angled, rough above or throughout on the angles : 

 leaves very long and rigid and carinate : spikes long and thick (three 

 or four inches long and one third inch thick), often bending over, 

 more densely flowered and comparatively shorter peduncled : lateral 

 staminate spikes sessile : perigynium nerveless and hard : scales much 

 as in the last, only blunter. The aspect of the spikes is variable, 

 owing to the size of the scales. They often closely resemble thick
