EKPOKT OF IIIE STATE BjTAN ST 1S9 



length, short-peduncled, with a lilifonn bract one-half the length 

 of the spike or more; pistillate spikes 2-5, compactly flowered, 

 exactly cylindrical, 2'-3' in length, usually one or more compound 

 at the base and sometimes sterile at the apex, the upper ones 

 mostly approximate and the lowest distant, all pendulous on fili- 

 form peduncles ^'-A' long ; bracts leaf-like, sheathless, rough on 

 both surfaces, much surpassing the culm; perigynia triangular- 

 lanceolate, prominently nerved, smooth, stalked, gradually 

 tapering into a short forked beak, the sharp teeth straight or 

 spreading; scale lanceolate, rough-awned, about the length of the 

 perigynia which are strongly reflexed at maturity. 



Shores and wet places. Common. July, August. 



Closely like the preceding when mature, but the spikes are 

 more evenly cylindrical, and the teeth of the jjerigynia* less 

 spreading, and not so strongly recurved. Also, in its early stage 

 it has been confounded with the next following species, which it 

 resembles, but its longer spikes and peduncles should distinguish it. 



Perigynia much inflated. 



Staminate spike single (rarely 2), stalked, sometimes fertile at 

 the summit or base ; pistillate spikes 1-i, approximate, or the 

 lowest distant and spreading, the upper subsessile and suberect or 

 all on short stalks, spreading or drooping, densely flowered, 

 squarrose. 



Pistillate spikes erect, 3" wide, perigynia S -nerved . , , Baileyi. 



Pistillate spikes 6" wide, ptrigynia 10-nerved tentaculata. 



Pistillate spikes b"-6" wide, the lower drooping liystricina. 



112 Carex hystricina 3fu/(L 

 Stems 15'-. 4' high, 'erect, acutely angled, rough above the 

 middle or near the summit, smooth and flaccid at the base ; leaves 

 mostly surpassing the culm, l^"-3" wide, rough above the middle 

 and on the margins ; staminate spike single (rarely 2), cylindrical, 

 l'-2' long, mostly short-peduncled, light brown ; pistillate spikes 

 2-3, oblong or cylindrical, densely flowered, £'-11' long, the 

 lowest often with I or 2 short branches at the base, approximate, 

 the uppermost subsessile and spreading, the others on short nod- 

 ding peduncles ; bracts leaf-like, with obsolete sheaths, much 

 surpassing the culm; or the highest often filiform and about 

 equaling it ; perigynia ovoid or ovate-lanceolate, smooth, many-
