 Stout and low, leafy up to the few subsessile heads; herbage 

 green but not sparingly villous or pilose: leaves rather 

 ample, suberect: bracts of involucre often red or purplish: 

 outer pappus of conspicuous linear or subulate palese. — Eocky 

 summit of hills around San Francisco Bay, and along the 

 middle Californian seaboard. Analogous to the Rocky 

 Mountain C. villosa, but perfectly distinct, and geographic- 

 ally widely separated from it.

 (1840). Rather slender, erect, 2 feet high, viscid-glandular 

 and sparingly hirsute: leaves oblong, acute, subsessile; heads 

 few and sessile, or nearly so, at the ends of the several fas- 

 tigiate terminal brauchlets: achenes strong appressed-pubeg- 

 cent: outer pappus indistinct, of few rather hmg setae rather 

 than pale^e. — From Santa Cruz to Santa Barbara, in the 

 Californian Coast hills. Species most distinct from all the 

 preceding, but nearly allied to the next.

 123 (1884). Rigid, strongly decumbent, strigose-pubescent 

 and glandular-scabrous: leaves oblong, obtusish: outer pap- 

 pus distinct, of linear or subulate short palese. — Mountains of 

 Utah and Arizona. First collected by the present writer, 

 and distributed by him in 1880, as a new species, under the 

 manuscript name C. glandulosa,
