Stems low and stout. 



Inflorescence paniculate. 



Montane form with erect stems var. rigida. 



Insular form with depressed or ascending stems 



var. robusta. 



Inflorescence virgate, scarcely branched, foliaceous with 



broad leaves var. glomerata. 



Heads large: involucre 10 to 12 mm. high var. Pacified. 



Tomentum persistent, even the involucre white at time of flowering. 



Leaves broadly oblong, rigid var. latifolia. 



Leaves linear, flaccid var. linifolia.

Slender, erect, 5 to 10 dm. high, woody below : herbage arach- 

 noidly tomentose, the tomentum sometimes deciduous, the inflores- 

 cence then glabrous or minutely glandular : leaves oblong-spatu- 

 late or oblanceolate ; the lower ones narrowed to a petiole and 

 sparingly serrate toward the apex ; the upper sessile and inclined 

 to be entire; those of the inflorescence reduced to bracts: heads 

 solitary and terminal on the branchlets or more numerous and 

 loosely panicled: involucre campanulate or broadly turbinate, 7 

 or 8 mm. high; its bracts imbricated in 4 or 5 series, narrowly 

 lanceolate, erect : rays 15 to 25, violet. 



Near the coast from Monterey southward, the typical form 

 rare south of Santa Barbara. In Monterey Co. the specimens 

 have a merely granular inflorescence; proceeding southward 

 along the coast we find forms in which the glandular pubescence 

 is more and more pronounced, until in Southern California a 

 majority of the plants have viscid stalked glands on the inflores- 

 cence (var. virgata). In the type specimens (of which I have 

 seen a sketch) the solitary heads terminate widely spreading 

 branchlets, but this form passes directly into one with numerous 

 paniculate heads. The following are only the extreme forms of 

 this very polymorphic species. 



Var. latifolia Hall, var. nov. Five dm. or more high; the 

 stems stout, woody below: herbage densely white-tomentose, the 

 tomentum not deciduous even from the involucres at time of 

 flowering: lower leaves narrowed to the base; principal cauline
