Despite its likeness to G. rostrata, and its desert habitat, the 

 flowers in this are subsessile, the calyx closed, the petals with 

 clear distinction of blade and claw. It is possibly a monotype.

8. campestris, Wats., by the specimens, as also by the original 

 description, was a sorry medley from the very outset. By the 

 specific name the plant from Campo must be received as the 

 type. The material of that is fragmentary ; but its calyx her- 

 baceous, purple, the sepals all alike and exact, not spreading. 

 It may well hold its place and name under Streptanthus until 

 better known. 



The plant of the San Bernardino Mountains mixed with the 

 above in books and lists is exceedingly remote from it in both 

 habit and character, and can not be consistently admitted into 

 any of my streptanthoid segregate genera. I name it in the 

 type of a new genus, 



Agianthus. Calyx almost that of Euclisia, nearly as irreg- 

 ular, its sepals thin, whitish, translucent, also loosely investing 

 the Euclisia-like petals, stamens, etc., but the whole calyx re- 

 markably short, each sepal broad and blunt at summit. Pods 

 large, narrow, more or less tortuous. Plants all perennial, in 

 foliage altogether much like Oartiera. Specimens of two species 

 are before me. 



A. BEKsrAEDiNtrs. Basal leaves cuneate-obovate to spatulate- 

 oblong, rather obscurely dentate mostly at and near the summit : 

 pods very narrow, almost 4 inches long, spreading or even re- 

 curved and tortuous. — San Bernardino Mountains, Parish ; also 

 San Jacinto Mountain, H. M. Hall, both as Streptanthus cam-
