A Journal of Botany 

 Issued at Irregular Intervals 



This first number is issued somewhat prematurely, in order 

 to furnish a medium for the simultaneous publication of the 

 " Changes in Nomenclature," which were crowded out of the 

 Catalogue of North American plants, enough space not having 

 been provided in that work to accommodate all of them. 



Other numbers will appear at early dates. They will con- 

 tain articles of general interest, both technical and non-technical, 

 treating not only of flowering plants and ferns, but of the lower 

 cryptogams as well. 



Subscription price $1.00 a volume, the volume to contain 

 not less^^than 150 pages.
