126 PROCEEDINGS OP THE AMERICAN ACADEMY 



Dry fields, Salem, Ipswich, and Dedliam, E. Massachusetts. First 

 found in this country in 1826, at Salera, by Dr. C. Pickering. Intro- 

 duced from Europe. 



» * Perigynium various, usually gradually beaked, the ribs not prominent or none. 



198. Carex inops. 



Culm slender but rigid, sharply angled, roughish, a foot high, from 

 long and erect root-stalks, twice longer than the numerous, narrow, 

 long-pointed and rigid leaves : spikes three or four, all aggregated 

 and sessile at the top of the culm, the lowest subtended by a sheathless 

 bract of about its own length, the terminal spike staminate and an inch 

 long, the others half as long and staminate at the top : perigynium 

 small, elliptic, nerveless or nearly so, brown below, very abruptly pro- 

 duced into a white straight and deeply cut beak, scabrous below, hairy 

 on the shoulders and beak, about the length of the brown-centred, 

 broad, acute scale. — Sandy grounds on subalpine slopes of Mt. Hood, 

 Oregon, July, 1884, L. F. Henderson. In aspect much like C. Penn- 

 sylvanica. It lacks the ribbed and hardened character of the perigynia 

 of that specieB and its allies, and the beak is straighter and more deeply 

 cleft. 



199. Carex Halleriana, Asso, Syn. PI. Arag. 135, t. 9, f. 2. 

 a alpestris, All. Fl. Fed. ii. 270. 



C. gynobasis, Vill. PI. Dauph. ii. 206. 



C. piano stachys, Kunze, Suppl. Riedgr. 138, t. 35. 



0. umbellata., var. vicina, Dewey, Bot. Mex. Bound. 232. 

 Culms slender, erect, rough on the angles above, shorter or longer 

 than the narrow, revolute, rough and rather rigid leaves, which are 

 sometimes somewhat recurved : staminate spike single, sessile or more 

 commonly peduncled, slender, an inch or less long: pistillate spikes 

 loosely few-flowered, those on the culm sessile or short-peduncled, the 

 radical ones long-peduncled : perigynium obovate or elliptic, very 

 strongly three-angled, green, much attenuated below, the short beak 

 often recurved, very strongly many-nerved, puberulent, shorter than 

 or equalling the green-backed and white-margined acute scale. A 

 well-marked species with much the aspect of loose C. umbellata. All 

 the European specimens which I have examined have broader and 

 blunter scales than our plants. Dr. Boott, however, figures an 

 Algerian specimen with very acute scales. — Texas : dry uplands at 

 Dallas, Reverchon; hills at Houston, Hall 753; woods on the Col- 

 orado, Wright ; Upper Guadaloupe, Lindheimer ; So. Mexico, Schiede. 

 Europe.
