EEPOET OF THE STATE liOTANIST. 91 



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

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

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

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

 mostly approximate and the lowest distant, all r)endulous on fili- 

 form peduncles ^-'-2' long; bracts leaf-like, sheathless, rouc^h on 

 both surfaces, much surpassing the culm; perigynia trian'^ular- 

 lanceolate, prominently nerved, smooth, stalked, gracfually 

 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 eveiily cylindrical, and the teeth of the perigynia less 

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

 it has been contounded with the next following species, which °it 

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



I'erigynia much inflated. 



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

 the summit or base; pistillate spikes 1-1, appro.ximate, 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 8-nerved . . , Baileyi. 



Pistillate spikes 6" wide, perigynia 10-nerved tentacidata. 



Pistillate spikes 5"-6" wide, the lower drooping hystricina. 



112 Carex hystricina Ifuhl. 

 Stems 15'-24' high, erect, acutely angled, rough above the 

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

 mostly surpassing the culm, U"-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, |'-1J' long, the 

 lowest often with 1 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-
