Contributions to Canadian Botany. 



By J AS. M. Macoun. 

 I. 



Since the publication in 1890 of Part V, of Prof. John 

 Macoun's Catalogue of Canadian Plants the geographical 

 range of many species has been extended, many additional 

 species have been added to the Flora of Canada and not a 

 fow species and varieties have been discovered that have 

 proved new to science. 



A record of these later discoveries has been kept by the 

 writer and it is proposed in these papers to publish such 

 notes as it is thought will prove "of general interest to 

 botanists. 



This plan will exclude such facts as are of local interest 

 onl}'. That a plant common in various parts of Ontario, 

 for example, should have been found in another part in 

 which it was not known to ^row, will not be considered of 

 sufficient general interest to be recoi-ded here but when the 

 plant is quite new to the country, of extreme raritj-, or of 

 very restricted distribution new stations for it will be con- 

 sidered worthy of record and when possible its habitat, 

 mode of growth etc., will also be given.
