119. Carex folliculata L. 



Stems 1 5-30' high, slender, erect, smooth ; leaves 2"-6" wide, 

 rough beneath, the lowest short and long-sheathing, the upper 

 surpassing the culm; staminate spike small and often inconspicu- 

 ous, y long or more, sessile or short-peduncled ; pistillate spikes 

 3-4, 10-20 subloosel}' flowered, globose-ovoid, 5''-8" broad, 

 approximate, distant or remote, the uppermost sessile, the lower 

 on exserted peduncles i'-l' long, all erect, green or tawny ; 

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

 lanceolate, many-nerved, inflated, smooth, widely spreading, 

 gradually tapering into a short bidentate beak, longer than the 

 ovate rough-awned, white scale. 



Swamps and wet places. Common. June, July. 



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 ^'-^'. 



120. Carex Michauxiana Bieckl. 



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

 1"-1^" 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 I'-V long, yellowish-green ; 

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

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

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

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

 (C. rostrata M.c., C. Michauxii Schw.) 



Swamps and bogs. Adirondack region. July. 



More slender than the last ; spikes fewer, more densely
