 species more abundant in other parts of Xorth America ; 

 snch as Arahis Drummondii, var. coimexa, common on Crow 

 Xnbble at the eastern end of Bradbnry's Island near Deer 

 Isle. With the exception of a station at Eiviere dn Lonp, 

 Quebec, this is the only occurrence in the East of this plant 

 of the mountains of western America. Another western 

 plant, Cornus canadensis, var. infermedia, frequent on the 

 sterile slopes of Mount Champlain, Isle an Haut, is knowm 

 elsewhere in the east only from Lal)rador and Xewfoundland. 



Thus far we have been primarily concerned with the exist- 

 ing ilora of the eastern Penobscot Bay region. It will be 

 well at this point to again call attention to some of the more 

 conspicuous absences among the native plants.
