CATALOGUE. 203 



Ceepis glauca, T. & Gr. Perennial, smooth and somewhat glaucous ; 

 leaves all radical, linear-spatulate, tapering into a short-winged petiole, apic- 

 ulate, nearly entire and deeply runcinate on the same plant ; stems 1-2° high, 

 with small linear bracts at the base of the 2-3 slender peduncles ; involu- 

 cres many-flowered, smooth, slightly calyculate, the proper scales linear- 

 lanceolate, scarious-margined ; achenia smooth, 8-10-ridged, slightly taper- 

 ing upward. — Heads smaller than in the last, the smoother forms of which 

 it approaches perhaps too closely. Plains of Nebraska to Oregon, (Greyer.) 

 Ruby Valley, Nevada, and on the foot-hills near Salt Lake City ; 4,500- 

 6,000 feet elevation ; May-July. (713.) 



Ceepis Andersonii, Gray. Perennial, 1-2° high ; leaves linear-spatu- 

 late or oblong-lanceolate, slightly toothed, runcinate or laciniate-pinnatifid, 

 glabrous, like the sparingly branched and leafless scapes ; bracts at the base 

 of the mostly monocephalous branches small and linear ; involucre of spar- 

 ingly puberulent herbaceous lanceolate unequal scales, imbricated in 2-3 

 rows, many-flowered ; achenia smooth, angled and many-ridged, fusiform 

 and tapering into a short beak. — In habit much like the last, but with a well- 

 marked imbricated involucre. Carson City, Nevada, (305 Anderson !) Hot 

 springs in Grrass Valley and Reese Valley, Nevada ; 4,500-5,000 feet eleva- 

 tion ; June, July. (714.) 



Ceepis occidentalis, Nutt. Perennial, canescent and scurfy-tomentose ; 

 stems 6-18' high, branching, leafy ; radical leaves with the petioles 6-9' long, 

 lanceolate, tapering both ways, acuminate, more or less deeply runcinate- 

 pinnatifid, with acute often toothed lobes ; cauline leaves similar, but smaller 

 and sessile; heads corymbed, 11-35-flowered ; involucres calyculate with a 

 few loose bractlets, the proper scales 8-10, 6-8" long ; mature achenia rather 

 stout, 3" long, tapering to the apex, evidently 10-striate. — This species varies 

 greatly in size, shape of leaves, and number of flowers in a head, but it has 

 larger and looser calyculate bractlets than the next, and a canescent or some- 

 times hispidulous involucre, and a greater number of flowers in a head. Ore- 

 gon and California to Nevada, Utah, and Colorado ; Carson City, (Ander- 

 son ;) Salt Lake City, (Mrs. Carrington.) From Western Nevada to the 

 Wahsatch, and on the shore of Stansbury Island ; 4,300-8,000 feet elevation;
