Many Newfoundland and Canadian plants doubtless inhabit 
southern Labrador: but I can add only one of these on the 
present list, namely, ine arenaria. Only about a dozen 
of these 57 ame appear to occur north of the 50th parallel on 
the Pacific coast: but this number includes much the larger part 
of the species on | this list which extend westward to the Pacific 
at all, even in a lower latitude 
The following 42 species range north of lat. 55°, but do not. 
as far as we know, cross the 60th parallel :

beyond Canada, and only in doubtful situations, but it seems to
