-I- Leaves or the lobes of ^innately parted leaves all linear and entire: stems often 



more or less woody at base. 



4. S. Douglasii, DC. White with cottony wool, or becoming nearly glabrous : 

 stems in tufts, 2 to G or 7 feet high, the lower portion or base persistent and even 

 elirubby, leiify to tho top : loaves linear, entire and acute (2 to 4 inches long and 

 less than 2 lines wide), or pinnately parted into 3 to U similar lob s : heads corym- 

 bose or sometimes nearly solitary terminating tho branches, rather large (half to two 

 thirds of an inch long) : involucre calyculate with loose slender Hubulato bracts, 

 some of them little shorter than the acute or acuminate proper scales of the involu-

Gravelly or rocky banks of streams, kc, from Ijako Co. southward through the State, and into 

 Arizona and Nevaila. ,S'. lomjiJolms, Benth., of Mexico, to which belongs S. filifoluis, S. sparti- 

 oidr.i, and probably S. Itidde/lu, Torr. k Gi-ay, with mostly smaller heads, more herbaceous 

 involucre, and shorter and few calyculate bracts, represents this in and ea.stward of tho Hocky 

 Mountain-s, and apparently passes into it. ^S^. Rrrjiomnnlanii.x, D(J. Prodr. vi. 429, is probably 

 another synonym, and the "Ileal dclMonto" of IlaMiko is Jfontcrey, California.

 or several and conspicuous : akenes r/lahrous. 



5. S. Bolanderi, Gray. Early glabrous : stem slender, a span to a foot or more 

 high from a slender creeping rootstock, sparsely leaved : nidical and lower caulino 

 leaves potioled and pinnately divided, tliin and nu'inbranaceous ; leaflets 3 to 7, 

 roundish or cuneato, incisely and obtusely lobed, tho terminal leaflet larger and 

 sometimes slightly cordate, the lower on the radical leaves often small or minute 

 and entire, on the cauline leaves stipule-like : heads few or snveml and corym- 

 bose : involucre nearly destitute of bracts at tho base : rays 4 to G. — Proc. Am.

6. S. eurycephalus, Torr. <^ Gray. Floccose- woolly or early glabrous : stem

 lyrato; lobes or leaflets 7 to 15, cuneato and acutely incised or cleft, or ii\ tho upper 

 loaves becoming linear : heads mostly numerous iu an ample corymb and large : 

 involucre broadly carapauulato, with very few and inconspicuous calyculate bracts : 

 rays 10 to 12, elongated. — PI. Fendl. 109. 



Low grounds, from Sonoma Co. and the Sacramento, along the Contra Costa Range, kc. A 

 very laige and coarse-leaved form (var. major, (Jray, in Parif. R. Rep. iv. Ill) in Calaveras Co., 

 near Murphy's, Bujdow. A variable species, both in foliage and the .size of the heads. These, 

 in the larger, two thirds of an inch long and fully half an inch broad, and bearing rnys Imlf an 

 inch in length : in specimens from Monte Diablo, in Kellogg and Harford's collection, of only 

 about half that size, not larger than those of S. aureus. 



7. S. aureus, T.inn. Very loosely floccose-wooUy when young, soon naked, or 

 oven glal)rous from tho lir,st, a foot or two high, or alpine forms .<;inaller : radical 

 leaves or somo of them entire or merely serrate, from round-cordate to oblong or 

 spatulate, slender-petioled ; the others mostly lyrately pinnatifid or lyrate, or only 

 incisely toothed ; upper sessile or partly clasping, spatvdato or lanceolate : heads 

 few or numerous, corymbose (3 to 5 lines high) : involucre scarcely calyculate : ray.s 

 8 to 12, occasionally wanting. — An exceedingly variable species; the typic4\l form 

 with thinnish and soon glabrous leaves, tin; nidical ones cordate or roundish and 

 toothed, and the lowest cauline apt to be lynte. 



Var. multilobatUS, Gray (or S. multilobatus, Torr. i^': Gray, V\. Fendl., and S. 

 Fendleri, Eaton in Bot. King Exp. in part), if perennial, is a form with thicki.sh
