 oblong-lanceulate) acuiuiiiate or acute leaves, all but the upiienuost with tapering

Var. incana, Gray. White with lloccose dense wool, which is deciduous with age. 



Wet meadows, in the Sierra Nevada, from Kern Co. {llulhruck) to Oregon ; extending east- 

 ward to lliu llocky Moiiulaius and Saskatdiewan. In California more commonly tlie var. incana : 

 l;aku Talioo {Jlrciocr) : Lako Waalioo (Torrey) : Sionu Valley, "in deep water," JMandtr. 

 Leaves from 2 or a to 5 or ti inchiis long, from 4 lines to an inch in width, mostly obtu.se ; tlio 

 upper closely sessile, the lower with tapering bases or petioles clasping at the insertion. Involu- 

 cre half an incli high, somewhat viscid-glandular under the deciduous pubescence, as is the herb- 

 age generally, not at all hirsute or hispid. Hays 4 or 5 lines long. Akenes minutely hairy or 

 glandular, or nearly glabrous. The white-woolly form is very strikuig ; but it passes insensibly 

 into Nuttall's A. foliosa ; of which A. lonyi/olia, Eaton in Bot. King Exp., may be also a form. 



8. A. alpina, ^lurr., Lajstad. A span to a foot and a half high, more or less 

 hirsute-pubescent, bearing stilitary or sometimes 3 long-peduncled mostly large 

 heads : leaves entire or sparingly denticulate ; the cauline in one tu 3 pairs, lanceo- 

 late or linear-lanceolate, the upper ones small ; radical ones spatulate, oblong, or 

 oval, about 3-n(U'ved : rays large, deep yellow. — A. anf/uiftifolui, Vahl in Fl. Dan.

In the Sieri-a Nevada (in meadows of Sieira Valley, Lemmon, &c.) ; thence north waid through 

 Oregon to the Arctic regions, and east to the Rocky Mountains and plains of the Missouri ; also 

 Greenland and high northern Eurojwj and Asia. Exceedingly variable. The Californian specimens 

 are large and rather broad-h-aved Ibrms. Kays three cpiarters of an inch long. J. alpina is the 

 moreai)jiropriate mmu', and is conceded to lie the older ; but wc cannot find it in "iMurr. Sy.sl. 

 Veg. 1774," as cited by Erics.

Head several - many-flowered, homogamous ; the ilowers all fertile, involucre 

 cylindraceous, naked at base ; the scales 7 to 14 in a single series, linear, equal, 

 lightly united into a tube or cup to or above the middle. Receptacle flat or barely 

 convex, naked. Corollas like tho.se of the disk in Arnica. Style-branches elongated, 

 hirsute, and produced beyond the long stigmatic lines into an acuminate tip. 

 Akenes linear, llattish, striate-nerved, hirsute. Pa})pus a single series of (20 to 25) 

 rather stout and rigid strongly ciliate-plumose bristles, about the length of the corolla, 

 bright white. — Acaulescent herbs (of the Sierra Nevada) ; with stout creeping 

 rootstocks, bearing tufts of linear or oblanceolato entire radical leaves, and a eim])le

Tiiis interesting genus, along with the Hawaiian llaUhirdla, seems rather to belong to the 

 Jlckiiiuidca-, next to Dubjutin ; but tlio technical characters would cause it to be looked for here.
