nerved, gradually tapering into a long, sharply toothed beak; scale, 

 ovate-lanceolate, rough-awned, shorter than the widely divergent 

 or horizontally spreading perigynia. 



Wet places. Very coram in. June, July. 



This species may be distinguished from the next by its longer- 

 stalked drooping spikes and by its smaller, many-nerred peri- 

 gynia. In cold, springy, sterile soil a small form occurs with 

 only one or two fertile spikes which are erect and nearly sessile. 

 The scales of the sterile spikes of this species and C. Pseudo- 

 Cyperus are strikingly alike. 



1 I 3 . Carex tentaculata, Muhl. 



Stems 18-30' high, erect or spreading, acutely angled above 

 the middle, rough at the summit, mostly smooth below : leaves 

 1} "-3" wide, rough, longer than the culm ; staminate spike linear, 

 very rarely with an additional short spike at its base, H'-%j/ 

 long, short-peduncled ; pistillate spikes 2-4, compactly flowered, 

 ovoid-cylindrical, l'-lV long, the upper two contiguous, sessile 

 or nearly so, erect or divergent, the others approximate or the 

 lowest sometimes remote on a short stalk, horizontally spreading . 

 bracts leaf -like, far surpassing the culm ; perigynia turgid-ovoid, 

 thin, about 10-nerved, widely divergent when mature, tapering 

 into a long, slender, roughly-toothed beak, about twice the length 

 of the linear-lanceolate, rough-awned scale; achenium ovoid, 

 minutely papillose, with a long curved persistent style. 



Wet places. Yery common. June, July. 



This species may be identified by the short-stalked, horizontally- 

 spreading lowest spike, and by the spreading, slender beaks of 

 the perigynia, which give to the spikes a coarse, comose appear- 

 ance. The name C. lurida, WaM., is applied to this plant in the 

 last edition of the Manual. Barely the staminate spike is fertile 

 at the apex. 



Yar. flaccida {Bailey). Smaller, with 2-4 loosely flowered, 

 approximate, sessile spikes V long or less ; the fruit longer than 

 in the type and less abruptly contracted into the beak; the 

 spikes of a dull or reddish-brown color. 



Yar. parvula Paine. A diminutive form 5-10' high with one 

 or two globose or ovoid sessile densely flowered reddish-bro^vn 

 spikes.
