LIST OF FOREST TREES IN ONTARIO. 



Most species of our native trees have synonymous names varying 



with locality. An example of this is the common maple of Ontario, 



which is called Sugar Maple, Rock Maple, and Hard Maple. To avoid 



confusion in this publication it is necessary to agree upon some common 



name. 



Canadian and American species have been given the vernacular and 

 scientific names adopted by Bulletin No. 17, of the Division of Forestry, 

 U. S. Department of Agriculture. The names adopted in Bulletin 17 

 are in almost every case known in Ontario ; so it has been felt advisable 

 to conform to this standard. One exception is the Hornbeam (Ostrya 

 virginiana), which in Ontario is commonly called Iron wood. 



The adopted names are given in large type with the synonymous 

 names in brackets.
