A. nemorosa, Linn. var. (?) Macoun, Cat. III., 478. 



When compiling Part III., I separated the western form of A. 

 nemorosa from the eastern one, being satisfied that it was a distinct 

 variety. Since then Dr. Gray has erected it into a new species under 

 the above name. All references in Part III. belong here. Not un- 

 common in low damp woods in the southern part of Vancouver Island, 

 1887. {Macoun.)
