 deep blue with purplish or whitish center, rotate-cam pan ulate, 

 10-20 mm. broad; capsule ovate, abruptly cuspidate-pointed,

 2.5-4 cm. broad, purplish or pale bluish; capsule equaling the

 purple ; appendages to the exserted filaments hairy. 



Occasional on low hills and in the chaparral belt. Verdugo Hills; San

10. P. Parryi Torr. Stems more or less branching, the 

 branches somewhat spreading; herbage hirsute or somewhat his-
