 C. macrantha, Eaton. A span high, rather simply branched from the base, canescently 

 tonientulose, partly glabrate : leaves short, with linear or oblong-linear lobes usually ap- 

 j)roximate : heads 12-20-flowere(l, mostly short-peduncled, or the earlier on longer naked 

 peduncles from uear the base of the stem : bracts of the involucre thinnish, more or less 

 tomentose : corollas half to three-fourths inch long, narrow, externally puberulent, all alike ; 

 the 5 short teeth linear-oblong, ascending or barely spreading : anthers v.holly included in 

 the throat, the tips lanceolate : papj)us of 4 linear-oblong ])aleaj barely half the length of the 

 corolla, .ind 2 to 4 very short cuneate-oblong ones, but these occasionally obsolete or wanting.

-t— H— -1— -1— Marginal corollas not distinctly larger than nor different from tlio others (the 

 lobes if slightly larger still regular): bract.s of many-flowered involucre linear or somewhat 

 spatnlate, obtuse, souietinies one or two loose and shorter outer ones: pappus of 8 to 14 mostly 

 equal and large obtuse palea5 : biennial, perennial, or suffrutescent plants : fl. summer. — Macro-

C. Douglasii, Hook. & Arn. Canescent with a fine somewhat floccosc or pannose tomen- 

 tum, or sometimes early glabrate, a span to a foot or more high from a biennial or more 

 enduring root : leaves mostly of broad outline and bipinnately parted into crowded short 

 and very obtu.se divisions and lobes : heads from half to three-fourths inch long, in larger 

 plants several or numerous and coi-ymbosely cymose : jialeiE of the pappus from linear-

 Dry plains and mountains, Montana to New Mexico, west to Washington Terr, and Cali-

 glabrate form, with sparser divisions to the leaves, and shorter spatulate-oblong jjaleai of 

 pajjpus. Very variable species. 



Var. alpina. Dwarf, 3 to 5 inches high, consisting of a rosette or thick tuft of leaves 

 with very approximate divisions, and miked or scapiforni stems, bearing mostly solitary heads, 

 surmounting the subterranean branches of a mnltici])ital perennial caudex or rootstock. —

 barely inch long), densely white-woolly, crowded, obovate or flabelliform-cuneate in outline, 

 once or twice pinnatifid or parted into obovate or sjiatulate-linear lobes : ])eduncies inch or 

 less long, bearing a s<jlitary rather narrow head. — Bot. Calif, i. 391. lliimevopappns Neva-
