with long spreading hairs . appendages of corolla united to the base of the fila-

20. P. circinatiformis, Gray. Erect, a span high, hispid and puberulent : 

 leaves ovate arid oblong-lanceolate, conspicuously parallel -veined, somewhat strigose : 

 racemes or spikes dense : corolla narrow, almost funnelform, little longer than the

 leaves oval or lanceolate, mostly shorter than the slender petiole : racemes simple, 

 soon loose ; the lower pedicels as long as the calyx : corolla open-campanulate, violet

Eastern foot-hills of the Sierra Nevada ( Watson), extending to Owens Valley, Dr. Horn. Re- 

 sembles P. humilis. Pedicels a quarter to half an inch long, even the lowest not commonly

24. P. rotundifolia, Torr. 1. c. Diffusely branched, slender, 2 to 4 inches
