This species has often been mentioned as occurring in Ontario and 

 has been published as such by myself under the next species, as I had 

 no means of separating them. At present we only know of its occur- 

 rence from Niagara River westward along Lake Erie to Amherstburgh.

We follow Professor Sargent, in including the boreal form of our 

 red oak with the more southern one, as we have never seen a series of 

 specimens complete enough to separate them. Not uncommon at 

 Halifax, Pictou and Windsor, and very likely many other places in 

 Nova Scotia. (Macoun.} Rather common in Kent, Northumberland 

 and York counties, N.B. (Fowler's Cat.} On the St. Lawrence between 

 Quebec and Malbaie, in Lat. 47 50'. (Michaux.} From thence west 

 ward through Quebec and Ontario, it is the common " Black Oak." 

 It is occasionally met with along the north shore of Lake Huron, and 

 east coast of Lake Superior, and appears for the last time on the 

 Dawson Route at Lake Namakeen on the height of land west of Lake 

 Superior. (Macoun.}
