The species is easily recognized by its short, lower stem leaves, 

 and by its usually distant green or yellowish, subglobose spikes. 

 On the sand plains west of Rome and in sphagnous marshes of 

 the Adirondack region a short form occurs, having the pistillate 

 spikes approximate, four of them being included in a space 

 of 2£'-3'.

Stems 10-20' high, stiff, smooth ; leaves exceeding the culm, 

 l"-iy wide, rough or sometimes smooth below the middle, 

 yellowish-green ; staminate spikes 3"-6" long, sessile, mostly 

 inconspicuous; pistillate spikes 1-3, densely flowered, globose- 

 ovoid, the upper contiguous and sessile, the lowest distant or 

 remote on an exserted peduncle j-'-l' long, yellowish-green; 

 bracts leafy, sheathing, longer than the culm ; perigynia lanceo- 

 late, numerously nerved, inflated, smooth, ereot, spreading or 

 widely divergent, tapering into a short, slender bidentate beak, 

 twice longer than the oblong, obtuse, light-brown scale.

Swamps and bogs. Adirondack region. July. 



More slender than the last ; spikes fewer, more densely
