drooping stalks ^'-1' in length, the lowest distant and pendulous ; 

 bracts variable, the lowest leafy, 2'-3' long, sheathing, the upper 

 setaceous ; perigynia ovate-lanceolate, 2V long, turgid, 2-ribbed, 

 obscurely nerved, spreading, tapering into a long smooth or 

 roughish, mostly entire beak, about one-third longer than the 

 acute, fringed, brown scale. 



Very rare. May, June. Oneida and Herkimer counties. 



Well marked by its glaucous leaves, and its short, yellowish or

Perigynia moderately iniiated. 



Staminate spikes 1-4, the terminal stalked ; pistillate spikes 

 2-5, sessile or short-stalked (the lower ones long-stalked in 99), 

 approximate or distant, ovoid, oblong or C3'lindrical ; bracts leafy, 

 longer or shorter than the culm ; perigynia ovoid or oblong- 

 conic, nerved, smooth or pubescent, somewhat coriaceous in tex- 

 ture, with a short bifid beak. 



Perigynia scabro-pubescent scabrata. 



Perigynia smooth or granular, pistillate spikes distant, 



purple polymorpha.

 Stems l°-2° high, rather stout, rough on the angles; leaves 

 numerous, the upper ones surpassing the culm, 2"-3 " wide, rough, 

 light-green ; staminate spike clavate, 6"-9" long, its peduncle 

 2"-6" in length ; pistillate spikes 3-5, cylindrical, densely flowered 

 above, thinly at the base, approximate or scattered, the upper 2 

 sessile and erect, the others on erect or spreading stalks h'-Ih' in
