Smecio. COMPOSITE. 411 



Low grounds, common from Santa Barbara to San Diego, and in all tlio southern part of the 

 State. Heads barely or less than half an inch in length. 



* * * Root perennial. 



■i- Leaves or the lobes of pinnately 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 glabroius : 

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

 shrubby, leafy to the top : leaves linear, entire and acute (2 to 4 inches long and 

 less than 2 lines wide), or pinnately parted into 3 to 9 similar lobjs : heads corym- 

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

 thirds of an inch long) : involucre calyculate with loose slender subtdate bracrts, 

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

 cre : rays elongated : akenes minutely canescent. 



Gravelly or rocky banks of streams, &c., from Lake Co. southward through the State, and into 

 Arizona and Nevada. S. lomjilobas, Benth., of Mexico, to which belongs S. filifolius, S. spartt- 

 oidcs, and probably S. EiddcJlii, Torr. & Gray, with mostly smaller heads, more herbaceous 

 involucre, and shorter and few calyculate bracts, represents this in and e;i.stward ot the ho(/ky 

 Mountains, and apparently passes into it. S. Hcgiomontanus, DC. Prodr. vi. 429, is probably 

 another synonym, and the " Real del Monte " of Hajnke is Monterey, California. 



-i- -i- Leaves broader, all or some of them piymately parted or pinnate: rays nuiiierous 

 or several and consjncuoios : akenes glabrous. 



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

 high from a slender creeping rootstock, sparsely leaved : radical and lower caulinc 

 leaves petioled and pinnately divided, thin and membranaceous ; leaflets 3 to 7, 

 roundish or cuneate, incisely and obtusely lobed, the terminal leaflet larger and 

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

 and entire, on the cauline leaves stipuledike : heads few or several and corym- 

 bose : involucre nearly destitute of bracts at the base : rays 4 to 6. — Proc. Am. 

 Acad. vii. 362. 



Sandstone bluffs, Mendocino Co., Bolandcr. Cascade Mountains, Oregon, Harford and Dunn. 



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

 rather stout, 2 feet or more high : leaves pinnately parted or divided, somewhat 

 lyrate ; lobes or leaflets 7 to 15, cuneate and acutely incised or cleft, or in the upper 

 leaves becoming linear : heads mostly numerous in an ample corymb and large : 

 involucre broadly campanulate, 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 Pange, &c. A 

 very large and coarse-leaved form (var. major. Gray, in Pacif. P. Rep. iv. Ill) m Calaveras Co., 

 near iMurnhy's, Biqclow. A variable species, both in foliage and the size of the heads. Inese, 

 in the larger, two thirds of an inch long and fully half an inch broad, and bearing rays halt an 

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

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



7. S. aureus, Linn. Very loosely floccose-woolly when young, soon naked, or 

 even glabrous from the first, afoot or two high, or alpine forms smaller : radical 

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

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

 incisely toothed ; upper sessile or partly clasping, spatulate or lanceolate : heails 

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

 8 to 12, occasionally wanting. — An exceedingly variable species; the tyi-ica torni 

 with thinuish and "soon glabrous leaves, the radical ones cordate or rouinlisli and 

 toothed, and the lowest cauline apt to be lyrate. 



Var. multilobatUS, Gray (or ,S'. multilobatus, Torr. & Gray, PL Fon.ll., and .V 

 Fendleri, Eaton in Bot. King Exp. in part), if perennial, is a form with tlu.-kisli 

 leaves, nearly all lyrately or otlierwise pinnately parted, and the heads numerous.
