North American Cyjjeracece. 399 



Hab. Rocky Mountains, Dr. James! collected in Long's 

 first expedition. This species, which is somewhat related to 

 C. jpulla, is very different from every other with which we are 

 acquainted ; and we have therefore given it the present name in 

 honour of its discoverer, Dr. Edwin James. The stigmas have 

 wholly fallen in the single specimen collected by Dr. James ; 

 but the lenticular nut indicates it to belong to the distigmatic 

 section. It should be observed here, that we have not been 

 able to consult the description of C. compacta of R. Brown, 

 which is placed in this group. The C. Jamesii in the analyti- 

 cal table of Schvveinitz, is C. Willdenovii. 



47. Carex Scouleri. 



Spikes all on filiform peduncles destitute of sheaths ; fertile 

 ones 3, oblong-cylindrical ; staminate ones 2, short, attenuate 

 at each extremity ; fruit exactly orbicular, plano-convex or 

 lenticular, regularly and minutely striate, erostrate, minutely 

 apiculate, broader and a little shorter than the dark purple, ovate 

 scale ; orifice minute, entire. 



Whole plant smooth and glabrous. Culm slender, about 18 inches 

 high. Cauline leaves 2 — 4 inches long, and scarcely a line wide. Spikes 

 ail somewhat approximate. Bracts setaceous, about the length of the 

 spikes, not sheathing at the base. Peduncles of the staminate and upper, 

 pistillate spikes about an inch long ; the lower one longer. Stam. sjnkes 

 6- — 8 lines long ; scales obtuse, tawnj-, with a whitish keel. Pist. 

 splices about an inch long, rather densely flowered ; the uppermost bear- 

 ing a few staminate flowers at the summit. Scales ovate, acute. Fruit 

 light brown, about a line in diameter, very lightly and regularly striate 

 longitudinally, convex on one side, nearly flat on the other. Nut round- 

 ish, flat. Stigmas 2. 



Hab. Observatory Inlet, on the western shore of America, 

 Dr. Scouler ! (under the name of C.frigida). 



Obs. a very distinct species from every other of this 

 group, and manifestly allied to C. limosa, from which it is 

 clearly distinguished by the characters given above.
