RKPOKT OF THK STATE BOTANIST. 85 



nerved, slightly turgiu, sc?j3ropubescent, contracted into a short 

 obliquely toothed beak^ exceeding the ovate acute or cuspidate 

 brown scale ; achenium obovate, acutely triangular. 



Scattered or in patches along streams and in wet places. 

 Common. June. 



A rather coarse but bright-green species with the fertile spikes 

 of a bristly or squarrose appearance when mature. It is some- 

 what stoloniferous. 



100. Carex filiformis L. 



Stems l°-3° high, slender, erect, obtusely angled, mostly 

 smooth ; basal bracts l'-2|^' in length, pointed, purplish-brown, 

 more or less fibrillose ; leaves 1"-1t" wide, carinate, prominently 

 grooved, smooth, rough-margined, becoming doubled or involute 

 when dry, shorter than the culm, the radical ones numerous and 

 longer; staminate spikes 1-3, rarely 4, clavate or cylindrical, 

 l'-2' in length, on a slender peduncle l'-2i' long, subtended by a 

 scale-like, bristle-tipped, or short setaceous bract; pistillate spikes 

 1-4, usually 2, cylindrical, densely flowered, or sometimes loosely 

 at the base, subdistant or remote, sessile, or the lowest short- 

 stalked, often staminate at the apex, \'-^\' in length ; perigynia 

 obtusely triangular, ovoid, nerved, of a thick coriaceous texture, 

 densely pubescent or tomentose, slightly inflated, contracted into 

 a short, sharply toothed beak, mostly covered by the ovate 

 lanceolate, pointed or rough cuspidate brown scale, the latter 

 usually widely spreading at maturity. 



Swamps and wet meadows. Common. June, July. 



This species may be recognized by the long sterile, and gray- 

 ish fertile spilces, and by the usually erect, narrow, carinate 

 leaves. It seems to prefer cold elevated swamps and bogs, 

 though by no means limited to them. 



101. Carex lanuginosa Mx. 



Stems 1 '-2° higa stout erect, acutely angled, roughish above 

 the middle; roct stock ^scinswhat creeping; leaves open and flat, 

 smooth, 1"-1^" wii>i6, shorter ihan the culm ; staminate spikes 

 1-3, \'-\y long, on sdfl' pecuneies \'-\\' in length; pistillate 

 spikes 2-4, ^'-V in lengtn, 24- "-3" thick, densely flowered, cylin-
