X. 74, & Bot. Calif, i. 390, with var. integrifoUa, which is more slender, fewer-flowered, and 

 usually eutire-leaved. C. glabriuscula, var. niegacephala. Gray, Jour. Bot. Nat. Hist. Soc,

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

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

 proximate : heads 12-20-flowered, mostly short-peduncled, or the earlier on longer naked 

 peduncles from near 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 wholly included in 

 the throat, the tips lanceolate : pappus of 4 linear-oblong palea; barely half the length of the 

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

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

 lobes if sliglitly larger still regular): bracts of many-flowered involucre linear or somewhat 

 spatulate, obtuse, sometimes one or two loose and shorter outer ones : pappus of 8 to 14 niosth' 

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

 crirjihiis, Nutt. 



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

 tum, or sometimes earl}' 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 obtuse divisions and lobes : heads from half to three-fourths inch long, in larger 

 plants several or numerous and corymbosely cymose : ]3alea3 of the pappus from linear- 

 ligulate to narrowly oblong and from half to three-fourths the length of the corolla, or in 

 marginal flowers shorter and broader. — Gray, Proc. Am. Acad. x. 74, & Bot. Calif. 1. c.

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

 fornia. From S. E. California, Palmer, an incomplete specimen of a peculiar large and 

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

 pappus. 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 naked or scapiform stems, bearing mostly solitary heads, 

 surmounting the subterranean branches of a multicipital perennial caudex or rootstock. — 

 Alpine region of the Rocky and Cascade Mountains in Colorado and Wyoming, of the 

 Sierra Nevada, California, and north to Washington Terr. Seems distinct from the fol- 

 lowing. 



C. Nevadensis, Gray. Very dwarf, in small tufts surmounting filiform branches of sub- 

 terranean rootstocks, mostly growing in volcanic scoriie or ashes: leaves small (half to 

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

 once or twice pinnatifid or parted into obovate or spatulate-linear lobes : peduncles inch or 

 less long, bearing a solitary rather narrow head. — Bot. Calif., 390. Hi/jnenopappus Nera-

C. santolinoides, Greene, in herb. Subcaulescent perennial : leaves all crowded on 

 short tufted shoots from a slightly ligneous crown, Avhite-tomento.se, linear in outline, with 

 broadish rhachis tliickly beset with small (line or so long) oblong obtusely few-lobed and 

 crispate divisions : peduncles scapiform, 4 to 6 inches high, simple or once or twice forked, 

 glandular and viscid : head half-inch high, rather narrow : pappus of 8 or 10 linear-ligulate 

 palea;, a little shorter than the corolla. — San Bernardino Mountains, above Bear Valley,

C. suffrutescens, Gray. Canescently tomentose, a foot or more high from decumbent 

 woody stems : leaves pinnately parted into 5 to 7 narrowly linear entire or rarely 1-2-toothed 

 divisions : heads solitary or scattered, on slender peduncles, tliree-fourths inch high : pappus 

 of 10 to 13 linear or narrowly lignhite-oblong palea; a little shorter than the corolla, or in 

 the outermost flowers considerably shorter. — Proc. Am. Acad. xvi. 100. — California, on the
