Rvdberg : Rocky Mountain flora 691 



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

 never subcordate or clasping at 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. platyphyllus^ as far as the writer knows, is found in Utah only, 

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

 former belong the following specimens : 



Utah: Cottonwood Canon, July, 1869, 5. Watson j8j ; City 

 Creek Canon, July 25, 1879, M. E. Jones 1080 ; also July 7, 1880; 

 same locality, July 4, 1883, Leonard iji, and Aug. 9, 1884, 208 ;

(It^Pentsteiuon Eatonii undosus Jones, Proc. Calif. Acad. 5: 

 715. 1895. 



. Perennial, with a woody caudex ; stem erect, ^-6 dm. high, 

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

 at both ends, 3-7 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- 

 brous, club-shaped, truncate ; capsule about I cm. long. 



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

 puberulent stem and leaves, the more acuminate upper leaves 

 and sepals.
