PREFACE TO THE THIRD EDITION. 



The greatly increased interest in Botany as a subject of 

 study in the schools of the Dominion has necessitated a revi- 

 sion and enlargement of the List of Common Canadian Wild 

 Plants. The following pages now include most of the wild 

 plants of Manitoba and the prairie region generally, as well 

 as those of the older Provinces. Plants known to be pecu- 

 liar to the west are indicated by the addition of the letters 

 "N.W." to the descriptionsj while the note " Atl. Prov." 

 sufficiently marks those peculiar to the east. No attempt 

 has been made to enter the plants of the Pacific coast. 



In accordance with suggestions from several teachers of 

 Botany a short list of the commoner cultivated plants has 

 been added, which it is hoped will be found useful. 



In connection with this revision, grateful acknowledg- 

 ments are due to many friends for valuable assistance, but 

 more particularly to Mr. Wm. Scott, B.A., Vice-Principal 

 of the Toronto Normal School, who has placed his splendid 

 herbarium at the writer's disposal and has revised all the 

 proofs; A. H. MacKay, LL.D., Chief Superintendent of 

 Education for Nova Scotia, whose extensive acquaintance 

 with the flora of the Atlantic Provinces has been of the 

 greatest service ; Professor Brittain of the Provincial Nor- 

 mal School at Fredericton, who has described most of the 

 New Brunswick plants ; Professor Bryce of Winnipeg ; and 

 last, but not least, Mr. Jno. Dearness of London, whose 

 accuracy in determination and diligence as a collector in 

 Western Ontario are well known. 



Toronto, June, 1897.
