CATALOGUE. 359 



staminate at top, the lower short-peduncled, with leafy bracts ; lower bract 

 exceeding the culm and with a short sheath ; stigmas 2 ; perigynium spread- 

 ing, obovate or elliptical, slightly tapering at ba,se, lenticular, apiculate, 

 bilobed or emarginate, the orifice toothed, nerved, a little shorter than the 

 acute or lanceolate dark-rusty scale, which has a whitish midrib. Root 

 stoloniferous ; culm 16-24' high ; leaves leathery, broad, erect, nearly equal- 

 ing the culm.— The short rusty-colored spikes, more spreading perigynia, 

 stouter culm, and more rigidly erect leaves are surely not of sufficient value 

 to separate this from C. Jamesii. Fort Pierre, Nebraska, (Hayden ;) Clear 

 Creek, Colorado, (Greene.) Ruby Valley, Nevada; 6,000 feet altitude; 

 September. (1,243.) 



Carex ? Young specimens, with thick broad leaves, amplectant 



at base ; spikelets 7, blackish, the terminal one staminate, the rest pistillate, 

 increasing in length from the top to the base ; perigynium eUiptical, tapering 

 at base and to a bifid beak above, mouth toothed ; scales black, with a rusty- 

 colored nerve ; too young for determination. It is either new or of near 

 affinity to C. Jamesii, though the perigynium seems to be nerveless. Meadow 

 at head of Washoe Lake, Nevada; 5,000 feet altitude ; May. (1244) 



Carex laciniata,^ Boott. (C. Wilkesii, Torr., Ms. C. Sitchensis, Dew., 

 not of Presc.) Spike elongated, brick-colored (light-rusty,) with 6 cylindric 

 elongated remote spikelets, the upper 1-2 staminate, the lower if present 

 small, (stamens bright-rusty,) the remainder pistillate, 2J-3J' long, densely 

 flowered, the upper ones or all having a few staminate flowers at the apex, 

 the lower long-peduncled, slightly nodding ; lower bracts very long, with 

 entire truncated sheath-like auricles ; stigmas 2 ; perigynium spreading, oval 

 or suborbicular-obovate, beaked, the mouth entire, emarginate or bifid, the 

 apex and margins sparsely toothed, more or less nerved, rusty-punctate, 

 lenticular-compressed, broader and shorter or longer than the lanceolate 

 hispid-aristate rusty-colored scale, which has a broad pale nerve and a ciliated 



' Carex Pjrescottiana, Boott. ( C. Barharw, Dewey, in Bot. Mex. Bound., not in Hayden's 

 Nebraska Coll.) Spitelets 6-10, cylindrical, densely flowered, sessile, the lower somewhat peduneled, the 

 staminate 1-2, slender, (sometimes thicker,) the rest pistillate with the fruit remote at base, the lower 

 with long leafy slieathless bracts ; stigmas 2 ; perigynia broadly oval, subiuflated, nerved, divergent, 

 beaked, the mouth emarginate-bidentate, ciliated, straw-colored or msty-punctate, broader and longer 

 than the obtuse ovate hispid cuspidate purplish 3-nerved scale. Culm 2-3° high, triquetrous, rigid ; 

 leaves 4" wide. — Indian Territory, on the False Washita between Fort Cobb and Fort Arbuckle, (Palmer 

 1852;) California, near Santa Barbara, (Parry, 1855;) the fruit young in both cases, but developed into 

 shape. The afSnity of this species seems ratlier to be with C. laciniata than with C. crinita as indicated 

 by Dr. Boott.
