THIS work is designed to present descriptions of all plants growing 

 independent of cultivation, in North America, here taken to include 

 Greenland, Central America, the Republic of Panama, and the 

 West Indies, except Trinidad, Tobago, and Curasao and other islands off 

 the north coast of Venezuela, whose flora is essentially South American. 



It will be published in parts at irregular intervals by the New York 

 Botanical Garden through the aid of the income of the David Lydig Fund 

 bequeathed by Charles P. Daly. 



It is planned to issue parts as rapidly as they can be prepared, tne 

 extent of the work making it possible to commence publication at any

 wood and N. L. Britton.

 R. Barnes and John M. Coulter of the Universitv of Chicago, Mr. Fred-
