Not uncommon iu the country along the north shore of Lake Ontario, and extending 

 more sparingly eastward through Quebec to New Brunswick and Nova Scotia. West- 

 wardly it disappears, according to Prof. Macoun, at Lake of the Woods. I have not cjuoted 

 the localities given in Hooker's Flora Boreali- Americana, viz., Labrador, mouth of the 

 Columbia, and eastern declivity of the Rocky Moiintains, as they probably refer to other 

 species.
