Very slender, 6 to 16 inches high; leaves and bracts very narrow, 

 almost filiform : spikes 1-3, small (two lines to six lines long, two 

 lines to three lines broad), sessile or the lowest very short-stalked, 

 brown-and-green, the upper usually ovoid or globular, and sometimes 

 very much reduced in size : perigyniura ovoid, small, nerveless or 

 nearly so, little inflated, the beak minutely toothed, about the length of 

 and broader than the acute purple-margined scale. — Moosehead Lake, 

 Maine, Smith, and northward to Lower Canada and New Brunswick, 

 Fowler. More material is needed. Singular specimens from Ungava 

 Bay, N. Labrador, coll. by Turner, 1884, appear to belong here. This 

 plant is said by Olney to occur in N. Minnesota.

 Six to sixteen inches high, stout : culm smooth or very nearly so, 

 longer than the flat leaves : lowest spike subtended by an abruptly 

 spreading leafy bract : pistillate spikes usually two, mostly closely 

 sessile (the lowest sometimes very short-stalked), densely and evenly 

 cylindrical, in typical specimens about an inch long, often shorter : 

 staminate spikes one or two, short and obtuse or nearly so : perigynium 

 broadly ovate, very short-beaked, the orifice nearly entire, a little 

 longer than the white-pointed scale, bladder-like and shining, very fra- 

 gile. Evidently too near the next. — Arctic America : " Cumberland
