324 COMPOSITE. Aster. 



leaves lanceolate or linear, acute, entire, or the lower obtusely serrate, rather rigid 

 (an inch or two long, 2 to 4 lines wide) : heads racemose or panicled, 4 or 5 lines 

 long : involucre campanulate ; its scales numerous and imbricated in several ranks, 

 thickish, linear, with short usually somewhat dilated and obtuse green tips, ap- 

 pressed, the outer successively shorter : rays about 20, purple or violet : akenes 

 compressed, minutely pubescent. — Torr. Bot. Wilkes Exped. t. 8. 



"California, Menzies," according to Herb. Banks : but in Herb. Hook, said to be from "N. W. 

 coast." Upper Sacramento, Br. Pickering. Fort Tejon, Dr. Horn, Dr. Hccrmann {A. Duran- 

 dii, Niitt., ex Durand, in Pacif. E. Rep. v. 8), and common in W. Nevada, mostly in a glabrate 

 form, the pubescence only on the ultimate branches. The species has been mistaken for A. fal- 

 catus, Lindl., which may indeed belong to it, and likewise with the next. It is not at all re- 

 lated to A. concolor, as Lindley supposed. 



9. A. Chamissonis, Gray. Glabrous, or above somewhat hirsute : stems 2 to 

 5 feet high, paniculately branched : leaves lanceolate, acute, entire, or the larger 

 obscurely serrate, 2 to 5 inches long, scabroiis with sparse appressed pubescence, or 

 glabrous ; those of the flowering branchlets becoming small or minute and squar- 

 rose-spreading : heads loosely panicled, 5 or 6 lines long : involucre broadly cam- 

 panulate or somewhat obconical ; its scales numerous and imbricated in several 

 ranks, thickish, linear or linear-spatulate, with short and rounded green tips, the 

 outer successively shorter : rays 20 to 25, purple or violet, nearly half an inch 

 long : akenes sj^arsely and minutely pubescent. — Gray, in Torr. Bot. Wilkes Exp. 

 341. A. Radida, Less, ex iS^ees. A. Chilensis, Nees Ast. 112; Torr. & Gray, 1. c. 

 A. spectabilis (?) Hook. & Arn. Bot. Beechey. 



Moist thickets, &c. , common from San Francisco to San Luis 01 )ispo, and probably elsewhere. 

 As this is not a Chilian species, and as Htenke's no less than Chamisso's plant (if the former be 

 of this species) must have been gathered in California, we ought not to continue the false name. 

 Probably this as well as the preceding was included by Nuttall under the species (still impub- 

 lished) which he proposed to call A. Durandii. That name it was formerly thought might be 

 adopted for the jn-esent species, but it appears strictly to belong to the foregoing. And so the 

 present may be named after the first, or next to the first, discoverer. 



++ ++ Involucral scales looser and 7nore foliaceotis. 



10. A. Douglasii, Lindl. Smooth and glabrous or nearly so : stem slender, 

 2 to 4 feet high, })aniculately branched : leaves lanceolate, acute, entire or rarely 

 serrate, mostly tapering at base, 2^ to 5 inches long : heads in a loose and leafy 

 panicle, 5 or 6 lines long : involucre hemispherical ; its scales glabrous, linear or 

 spatulate-linear, mostly green except the base, loosely imbricated, the outer little 

 shorter : rays 25 or more, purple, half an inch or more in length. 



Moist soil, northern part of the State and in the Sierra Nevada ; common northward. 



11. A. adscendens, Lindl. (?) Smooth and glabrous or nearly so : stems rather 

 simple, a sjian to two feet high : leaves lanceolate or the lower oblong-spatulate, 

 entire : heads few, panicled or corymbose, peduncled, half an inch long : involucre 

 hemispherical ; its scales glabrous, linear or oblong, obtuse, chiefly green, few- 

 ranked, and of nearly equal length : rays, &c., as in the preceding. 



In the High Sierra Nevada, Yosemite Valley to foot of Mount Dana (Bolander), near Donner 

 Lake {Torrcy, Greene), and eastward in the Humboldt and Rocky Mountains. Whether this 

 belong to the original A. adscendens or no, it is the var. Parryi, Eaton in Bot. King's Exploration, 

 and apparently the same as the plant of the Colorado Rocky Mountains. 



12. A. integrifolius, Xutt. Yillous-pubescent when young, becoming glandu- 

 lar and viscid toward the summit : stem rather stout, simple, a span to a foot or 

 more high : leaves oblong-lanceolate and the lower spatulate, entire, thickish, 2 to 4 

 inches long, with strong midrib and inconspicuous veins ; the upper clasping : heads 

 few or several, somewhat racemose or corymbose, half an inch long : involucre cam- 

 panulate ; the loosely imbricated scales nearly equal in length, lanceolate, the inner 

 ones thin and without green tips, the outermost partly foliaceous, all glandular- 

 pubescent : rays 1 5 to 25, bluisli-purple : akenes pubescent : pappus rather rigid.
