6. MERTENSIA, Roth. LUNGWORT.

 leaves mostly oblong or spatulate-lanceolate, rather succulent : flowers in a 

 somewhat close cluster : lobes of the calyx lanceolate or linear, mostly acute. 

 From British Columbia southward, through the mountains of Montana to 

 Utah and Arizona. 



t- - Tube of the corolla little or not twice longer than the throat and limb. 



2. M. Sibirica, Don. Stems tall, I to 5 feet high ; pale and glaucescent, 

 glabrous and smooth or nearly so, very leafy : leaves ample, veiny ; cauline

 acum'nate apex; the lowest ovate or subcordate (3 or 4 inches long): short 

 racemes panicled : calyx-lobes oblong or oblong-linear, obtuse, commonly ciliolate,

 tains of Colorado westward to the Sierra Nevada, and far northward. 



3. M. paniculata, Don. Greener, roughish and more or less pubescent:
