the corolla and 4 cuneate-oblong ones three or four times shorter. Bot. King Exp. 

 171, t. 18. 



Western 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 

 inch long, on short slender peduncles. Corollas flesh-colored, some of the marginal with more or 

 less enlarged limb. 



w- ++ -H- Scales of the involucre obtuse or pointless : pappus 0/8 to 12 similar oblong- 

 linear scales, little shorter than the flesh-colored corolla : leaves commonly twice pin- 

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



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

 biennial root, white-tomentose 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. achilleaifolia, Hook. & Arn. ; Torr. in Stans- 

 bury Rep. t. 6. Ifymenopajjpus Douglasii, Hook. Fl. i. 316. 



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 lobes, white 

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

Alpine region of the Sierra Nevada ; Lassen's Peak (Brewer, Lemmon) ; above Summit (Kel- 

 logg) ; Mono Co., Muir. 



2. Pappus wanting: scales of the involucre acute. ACARPH^EA, Gray. 



13. C. artemisiaefolia, Gray. Somewhat viscid-pubescent, a foot or two high : 

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

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

 scales of the involucre linear-lanceolate : corollas apparently flesh color (rather than 

 "pale yellow"); the marginal ones little or hardly at all enlarged. Acarphwa 

 artemisicefolia, Gray, PL Fendl. 98 ; Bot. Mex. Bound. 95, t. 32. 



Near San Diego, Coulter, Parry, Clevelaiid. 



78. GAILLARDIA, Fougeroux. 



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

 3 series ; the outer larger, foliaceous and taper -pointed, spreading or at length re- 

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

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

 which may be taken to represent chaff. Eays cuneate, palmately 3-cleft at the 

 end : disk-corollas elongated-cylindraceous, with 5 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 6 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 

 many-jointed hairs ; the leaves alternate, mimitely impressed-punctate, varying from 

 entire to incised or even pinnatifid ; heads solitary and long-peduncled, large and 

 showy ; disk-flowers usually purplish or brownish ; the rays yellow or partly dark 

 purple.
