stamen is filiform. In P, platyphyllus the leaves are less glaucous, 

 never subcordate or clasping at thp base; the calyx -lobes are ovate, 

 long-acuminate, with more or less spreading tips; the anthers are 

 merely papillose-hispidulous on the margins but otherwise without 

 pubescence; and the sterile stamen is decidedly broadened upwards. 

 P. platyphyllus^ as far as the writer knows, is found in Utah only, 

 while P. Jaffrayanns grows in California and Oregon. To the 

 former belong the following specimens :
