tomentose above and beneath ; heads an inch high and nearly as 

 broad ; ovate-acuminate, weakly spinescent involucral bracts rather 

 closely appressed, their margins distinctly ciliolate ; reddish corollas 

 with remarkably wide cylindrical throat and similarly wide linear 

 and cuspidate segments of about equal length ; anther-tips with an 

 abrupt long mucro ; pappus bright-white, that of the marginal achenes 

 barbellate, of the others strongly plumose. 



At an altitude of 4,500 feet in Little Bear Valley, of the San 

 Bernardino Mountains, southern California, S. B. Parish, 1884, n. 

 1,686. This was distributed as C. Californicus ; but the flowers can- 

 not have been examined by Dr. Gray ; or scarcely the involucral 

 bracts. It is a most excellent species.
