Check En of Canadian Plants. 
There has been published and is now offered for sale what is 
believed to be a complete list of the Phænogamous and Vascular Cryp- 
togamous Plants of Canada. The Catalogue of Canadian Plants issued 
by the Geological Survey of Canada has been used as a basis, but a 
large number of species discovered since it was published have been 
included in the list. Many genera, too, have been revised by specialists, 
and their revisions have been used in the preparation of the Check-List. 
Several additional species discovered last year (1890) are included 
The price of the list is 50 cents per copy, 3 copies for $1.00.
