leiives liuiceoliilo nv linear, ivcnto, I'liliiv, or tho lower obtusely serrate, rather rij^'id 

 (an inch or two lou;^^, 2 to 4 lines wiilu) : heads racemose or jiaiiicled, 4 or 5 lines 

 Ion*,' : invohiero caiiipaniiluto ; its scales nuiuerous and imbricated in several ranks, 

 thickisli, linear, with short usually somewhat ililated uud obtuse green tips, ap- 

 pressed, the outer succc^ssively shoiier : rays about 20, purple or violet: ukenes 

 com})ressed, minutely pubesceut. — Torr. Bot. Wilkes Exped. t. 8. 



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

 coast." Upper Sacramento, 7>r. Pickering. Fort Tejou, Dr. Horn, Dr. llccrmann (^A. Duran- 

 (Hi, Nutt., ex Durand, in Paeif. R. Rep. v. 8), and common in \V. Nevada, mostly in a glabrate 

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

 caiiis, Lindl., which may indeed belong to it, and likewise with tho ne.\t. It is not at all re- 

 lated to A. conculor, as hindley siiliposed. 



0. A. Chamissonis, Gray. CJlabrous, or above somewhat hirsute : stems 2 to 

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

 ttbscurely serrate, 2 to 5 inches long, scabrous with sparse appressed pubescence, or 

 glabrous ; those of the dowering branchlets beconung small or minute and scjuar- 

 rose-spreuding : heads loosely panicletl, 5 or G lines long: involucre broadly cam- 

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

 nudts, thickish, linear or liuear-spatulate, with short and rounded green tips, tho 

 outer successively shorter: rays 20 to 25, ]»ur])le ov violet, nearly half an inch 

 long: akeiies sparsely and minutely pidie-scent. — Gniy, in Torr. Hot. AVilkos Mxp.

 A. speclabUis (1) Hook. & Am. liot. i>eechey. 



Moist tliickets, &.c., common from San Francisco to San Luis Obispo, and probably elsewhere. 

 As this is not a Chilian species, and as Hsenke'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 unpub- 

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

 adopted for the present species, but it appears strictly to belong to the foregoing. And so the 

 I)resent may be named after the first, or next to the first, discoverer. 



-h+ -h+ Involacral scales looser and more foliaceous. 



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

 2 to 4 feet high, paniculately branched : leaves lanceolate, acute, entire or rarely 

 serrate, mostly ta[)ering 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 

 spatulatedinear, mostly green excejjt 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 tho Sierra Nevada ; common northward. 



11. A. adscendens, T.indl. (1) Smooth and glabrous or nearly so : stems rather 

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

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

 hendspherical ; its scales glabrous, linear or oblong, obtuse, chietty 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 (Bulander), near Donner 

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

 belong to the original ,t. iK/sccndmi.'i or no, it is tho var. Parri/i, Katon in Bot. King's Exploration, 

 and apparently the same as tlio plant of tho Colorado Rocky Alountains. 



12. A. integrifolius, Nutt. Villous-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 inconspucuous 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 15 to 25, blui>>h-purple : akenes pubescent : pappus rather rigid.
