Stout and very leafy; spikes four to six, very large and heavy 

 at maturity, but narrower than In the species (2 to 4 in. long and 



in. wide), cylindrical, alternately disposed, all, or particularly 

 the lower, short-peduncled, erect, the lowest one or two sub* 

 tended by broad, leafy bracts which far exceed the culm ; stami- 

 nate spike 2 to 4 inches long, sessile, or at least not conspicuously 

 peduncled ; perigynium large and much inflated, somewhat 

 spreading, bright straw-colored at full maturity; scales hispid at 

 the tip. The characters which particularly distinguish this plant 

 from var. pedimculata are the long and cylindrical spikes, the 

 great bracts, shorter peduncled staminate spike, and more spread- 

 ing perigynia. Distinct in appearance. New York and New 

 Jersey; not common.

Very like C. htpidina^ Muhl, var. polystachya, Schw, & 

 Torr., from which it is distinguished by its much more scattered 

 and slim spikes, which are more loosely flowered; perigynium 

 very abruptly contracted into a slender beak three or four times 

 as long as the body, spreading at right angles or very nearly so, 

 little inflated, never becoming straw-colored; scales narrower, 

 smooth. A much more graceful carex than the other, with ma- 

 ture specimens of which it can never be confounded. Boott's
