'W estem borders of Nevada (Newberry, Watson, Lemmon) ; therefore probably within the 

 State : extends east to S. Utah, Capt. Bishop, Parry. Heads from half to three fourths of an

 less enlarged limb. 



4- +■ -f- Scales of the involucre obtuse or pointless : pappus of 8 to 12 similar oblong-

 natifid into fine and short very obtuse lobes. (Macrocarphus, Xutt.) 



.11. C. Douglasii, Hook. & Am. A span to 2 feet high, from an annual or 

 biennial root, white-tomeutose or glabrate : leaves narrow-oblong in outline ; the 

 lobes very many and crowded : heads corymbose, rarely solitary (half to two thirds 

 of an inch high). — C. Douglasii & C. achilleafolia, Hook. & Am. ; Torr. in Stans-

Through the Sierra Nevada, thence through Oregon and east to Wyoming and Colorado. 



12. C. Nevadensis, Gray. Less than a span high, depressed, in a perennial 

 tuft : leaves with ovate or cuneate general outline and much fewer lubes, white 

 woolly : heads solitary, on peduncles a little surpassing the. crowded leaves. — Hyme-

 the naked summit paniculate, bearing slender-peduncled rather small heads : leaves 

 1 — 3-pinnately divided or parted, the small ultimate divisions short and linear:

Head many-flowered, with several neutral rays. Scales of the involucre in 2 or

 flexed above the coriaceous and appressed base ; the inner smaller and partly scari- 

 ous. Peceptacle convex or hemispherical, with one or more awns among the flowers 

 which may be taken to represent chafl'. Kays euneate, palmately 3-cli ft at the 

 end : disk-corollas elongated-cylindraceous, with ."> pointed teeth, which are bearded 

 with jointed hairs. Anthers with long ovate-lanceolate tips, style branches tipped 

 with a bristly tuft, and extended beyond it into a filiform hispid appendage. 

 Akenes obpyramidal or oblong-turbinate, each surrounded by a tuft of villous hairs. 

 Pappus of G to 10 hyaline chaffy scales, traversed by a strong midrib, which is con- 

 tinued into a naked awn of about the length of the corolla, or in the sterile rays 

 the scales awnless. — Scabious like herbs, all North American, pubescent, with
