to the Rocky Mountains. 233 



Obs. Remarkable for its almost sessile leaves. Dr. Bald- 

 win had considered it as a new species, but as Dr. Beck's des- 

 cription was published first, his name must be adopted. The 

 upper lip of the corolla is not always remarkably villous.

M. ciliata, Beck, 1. c. ? 



Hab. On the Missouri. Dr. Baldwin. 



Obs. This appears to be a species intermediate between 

 M. ciliata and hirsuta. From the former it differs in its very 

 hairy white stem, petiolate and more acute leaves, and more 

 distinctly bilabiate calyx ; from the latter in its longer leaves 

 and bracts, shorter petioles, and particularly in its calyx ; 

 the upper teeth in M. hirsuta being very short and ovate. 

 Dr. L. C. Beck seems to have found the same plant near St. 

 Louis on the Missouri, and supposes it may be a new species.
