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

 never subcordate or claspingat the 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. platypiiylhis, as far as the writer knows, is found in Utah only, 

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

 former belong the following specimens :

Perennial, with a woody caudex ; stem erect, -i-G dm. high, 

 puberulent ; basal leaves petioled ; blades ovate or elliptic, acute 

 at both ends, T^—y cm. long, densely puberulent ; lower stem-leaves 

 spatulate to elliptic ; the upper ovate or ovate-lanceolate, acuminate ; 

 inflorescence lax, more or less secund ; calyx about 5 mm. long, 

 puberulent ; lobes broadly ovate, abruptly short-acuminate, scarious- 

 margined and denticulate ; corolla red, about 2.5 cm. long, nearly 

 tubular, not ventricose, slightly bilabiate, lobes short, rounded ; 

 anthers papillose on the margin, glabrous ; sterile stamen gla-

This has been confused with P. Eatonii, but differs in the 

 puberulent stem and leaves, the more acuminate upper leaves 

 and sepals.
