 dotted with dark purple, 10-12 mm. long, puberulent on the outer surface, the broad middle lobe 

 of the lower lip crenulate. ■ 



Usually in waste places, mainly in the Transition Zones; Washington to southern California and across

 slender petiole at base; flower clusters crowded into narrow dense terminal spikes, and often 

 also in the upper leaf axils; bracts ovate to oblong, their teeth awn-pointed; calyx 12-15 mm. 

 long, the teeth acuminate, upper one ovate-oblong, the others narrower and shorter ; corolla light 

 blue, but little exceeding the calyx, villous on the outer surface. 



Mostly in gravelly soil, Transition and Canadian Zones; widely spread over North America; in the Pacific 

 States ranging from Okanogan County, Washington, to the Blue Mountains and Lake County, Oregon. Type 

 locality: "Around Fort Mandan, on the Missouri." June— Aug. 



10. PRUNELLA L. Sp. PI. 600. 1753. 



Perennial herbs with slender rootstocks, petioled leaves, and rather small flowers in
