92 KEPUKT OF THffi STATE JiOTANISf. 



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 common. June, July. 



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

 stalked drooping spikes and by its smaller, many-nerved 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 strikinglj^ alike. 



113. Carex tentaculata, Muhl. 



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

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

 li'-S" wide, rough, longer than the culm ; staminate spike linear, 

 very rarely with an additional short spike at its base, H'-2y 

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

 ovoid-cylindrical, 1-14' 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 Avhen 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. Very 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, TTald., is applied to this plant in the 

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

 at the apex. 



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

 approximate, sessile spikes 1' 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 



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

 or two globose or ovoid sessile densely flowered reddish brosvn 

 spikes.
