"P. sericea, Gray. A span to a foot high from a branching caudex, silky-pubescent or 

 canescent, or the simple virgate stems and inflorescence villous-hirsute, rather leafy to the 

 top : leaves pinnately parted into linear or narrow-oblong numerous and often again few- 

 cleft or pinnatifld divisions, silky-canescent or sometimes greenish ; the lower petioled ; 

 the uppermost simpler and nearly sessile : short spikes crowded in a naked spike-like 

 thyrsus : corolla violet-blue or whitish, very open-campanulate, cleft to the middle : anthers 

 short-oval : style 2-clef t at the apex : capsule ovate, short-acuminate, a little longer than

 anthers short : calyx-lobes linear : style 2-cIeft at apex ; capsule ovate, acuminate or acute. 



' P. Pranklinii, Gray. A span to a foot or more high, soft-hirsute or pubescent : stem

 bipinnately divided or parted into numerous and short linear-oblong divisions or lobes, the 

 upper sessile and less divided : spikes cymose-glomerate or crowded, little elongated in age : 

 corolla pale blue or almost white : ovules 40 or more : capsule about the length of the
