Leaves thickish, somewhat succulent, 2 to 4 cm. long, .2 to 

 1.5 cm. broad, the lower oblanceolate subentire, those of the

 obtuse lobes. 



Lower California : Cape San Quentin, 10 May, 1885, Greene 



(Gray Herb.), co-type. 



The thick leaves of this variety give the plant a somewhat 

 different appearance from typical forms of the species; but 

 an examination of a large suite of specimens shows numerous 

 transitional forms such as those secured by Frltchcy, Prlngle, 

 Bigelow, Palmer 200, Orcutt 708, and K. Brandegee.
