Lake, B.C. Lat. 58'' 30'. {Dr. G. M. Dawson.) The western 

 specimens differ slig^htly from those from the east, but seem 

 referable here. This plant is readily distinguished from V. 

 blandn, V. retiijolia, and V. amosna by its "stout scaly-looking 

 and elongated root-stock and by its notably toothed foliage, 

 the leaves in all the others being crenate, the proper teeth 

 never salient but on the contrary almost obselete." The 

 lowest petal is not only purple-veined but the purple colour 

 is diffused over the whole petal.

Stellaria media, Cyrillo. 



Attention is again drawn here to Mr. Theo. Holm's paper 

 on "Allies of Stellaria media'" in the last number of The 

 Ottawa Naturalist. These plants should be carefully 

 studied everywhere in Canada. Among our herbarium speci- 

 mens labelled S. media, S. nc^lecfa was found from Victoria, 

 Vancouver Island; Burrard Inlet, B.C., Killarney, Man.; 

 Sable Island, N.S.
