ANNOUNCEMENT 



North American Flora is designed to present in one work de- 

 scriptions 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 Curacao and other islands 

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



The work 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, the ex- 

 tent of the work making it possible to commence publication at any number of 

 points. The completed work will form a series of volumes with the following 

 sequence : 



Volume 1. Myxomycetes, Schizophyta. 



Volumes 2 to 10. Fungi. 



Volumes 11 to 13. Algae. 



Volumes 14 and 15. Bryophyta. 



Volume 16. Pteridophyta and Gymnospermae. 



Volumes 17 to 19. Monocotyledones. 



Volumes 20 to 34. Dicotyledones. 



The preparation of the work has been referred by the Scientific Direc- 

 tors of the Garden to a committee consisting of Dr. N. L. Britton, Dr. W. A. 

 Murrill, and Dr. J. H. Barnhart. 



Professor John M. Coulter, of the University of Chicago ; Mr. Frederick 

 V. Coville, of the United States Department of Agriculture ; and Professor 

 William Trelease, of the University of Illinois, have consented to act as an 

 advisory committee. 



Each author will be wholly responsible for his own contributions, being 

 restricted only by the general style adopted for the work, which must vary 

 somewhat in the treatment of diverse groups. 



The subscription price is fixed at $1.50 for each part; it is expected 

 that four or five parts will be required for each volume. A limited number of 

 separate parts will be sold at $2.00 each. Address :
