 short and reduced to sheaths : staminate flowers 3-8, their scales oblong or 

 lanceolate, green with hyaline margins, appressed; pistillate flowers 1-4, 

 their scales green with ovate scarious-margined base and long acuminate 

 tips, sometimes longer than the spike: perigynium large, green, triangular

 oidal, densely-flowered, 5-8 lines long, 2-4 lines thick, staminate above : 

 scales membranaceous, deciduous, of the staminate flowers linear-oblong, 

 acutish : of the pistillate darker, ovate- lanceolate or oblong-lanceolate, the 

 lowest often cuspidate or subfoliaceous : perigynium membranaceous, lan- 

 ceolate or spindle-shaped, gradually attenuate to an acute obliquely cut, 

 hyaline-margined orifice, long-stipitate, reflexed at maturity, rather longer 

 than the scale. On the high mountains, northern California to Alaska and 

 the Rocky Mountains.

 inches high, very leafy at'base: leaves 1-5 lines wide, not half as long as 

 the stem, flat, attenuate to a very sharp point: spike very dark brown or 

 black, oblong to obovate, 3-6 lines long, staminate at the top : scales ob- 

 long to ovate, acute or acuminate: perigynia broadly lanceolate or oblong, 

 abruptly contracted below to a slender stipe, produced above into a slender 

 sharply 2-toothed beak, usually longer than the scale. In wet meadows 

 on the highest mountains, California to Alaska and the Rocky Mountains.
