368 BOTANY. 



This seems to be a very distinct species, inhabiting high latitudes and 

 altitudes. Dr. Boott, in his Illustrations, refers it as a variety to C. vulgaris. 

 It has a stouter culm than that species, v^^ith longer and broader leaves and 

 bracts, rough upon the edges. Its perigynium is also nearly nerveless. In 

 Fl. Rossica it is referred to C. aquatilis, Var. /^. In Fries' Summary, p. 229, 

 where this was described, there is evidently an omission of the syllable di 

 before stigmaticis. 



Caeex vulgaris, Fries, Var. juncella, Fries. (C. aquatilis, Var. nar- 

 difolia, Wahl. C. angustifolia, Sm.) Spikelets 4-5, terminal one staminate, 

 (stamens brick-colored,) the remainder pistillate, the upper ones approximate 

 and the lower remote ; stigmas 2 ; perigynium green, nerved ; scale black. 

 Spikelets, culm, and leaves all slender, the latter elongated, " convolute-fili- 

 form, " (Fries,) or " flat and convolute, " (Boott.) — Swedish Lapland speci- 

 mens from Prof Andersson have their leaves flat. On the shores of Cotton- 

 wood Lake in the Wahsatch, and on Provo River in the Uintas ; 7-9,000 

 feet altitude ; July. (1,241.) 



Carex Jamesii, Torr. Spikelets 5-6, the lowest sometimes peduncu- 

 late or rarely radical on a long peduncle, the two upper ones staminate, black- 

 ish-purple, (the stamens brick-colored,) the lower one small ; pistillate spike- 

 lets 3, sometimes 4, oblong, cylindrical, densely floweredj the uppermost 

 sometimes with a few male flowers ; bracts leafy, not usually sheathing, the 

 lowest sometimes short-vaginate and exceeding the culm ; stigmas 2 ; peri- 

 gynium obovate, strongly nerved, glaucous or hght-brown, the beak bidentate 

 or emarginate with the mouth slightly ciliated or toothed, longer than the 

 purplish-black scale, which has a greenish-white midrib ; achenium orbic- 

 ular. Whole plant glaucous ; culm 8-20' high ; leaves broad, leathery, 

 shorter than the culm, amplectant at base, the lower spreading and then 

 incurved, with pale sheaths. — From the Platte, (48 Greyer, according to 

 Boott,) to Colorado, (James, Nuttall,) and New Mexico, (887 Fendler;) 

 Southern Oregon, (Cronkhite, at 4,200 feet altitude;) California, Silver 

 Valley, (Bolander, at 8,000 feet altitude.) In Diamond and Ruby Valleys, 

 Nevada, and in the "Wahsatch, near Salt Lake City ; 4,500-6,000 feet alti- 

 tude ; May-July. (1,242.) 



Var. (C. Nebrasliensis, Dewey. Sill. Jour., n. s., 18. 102.) Spikelets 

 5-6, the two upper ones staminate with the lower one smaller, the remainder 

 (3, sometimes 4) pistillate, short-cylindrical, densely flowered, the upper one
