This species so often alluded to in the above references 
must be placed in the doubtful list as we are unable to cite 4 
single fertile plant from any part of North America.

This species founded on sterile apkercdiia will wave to be 
placed in the doubtful list unless fertile specimens can be 
found. It is unfortunate that it was ever given a name!

‘*Portage La Lochs, lat. 57°, Macoun.” I have seen 10 | 
specimens of this species. Mr. Pearson writes me that n0 
specimens exist in either of the parts of the Austin collection) 
nor does Mr. Macoun, its collector, possess any specimens. 
In order to facilitate the determination of our species 1 ap | 
pend the following table with the more important characters 
emphasized.

° Dumortier clearly intended to write ‘‘pusilla’’ at this reference. but yr
