ANNOUNCEMENT 
NortH AMERICAN Flora is designed to present in one work 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 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 Gymmnospermae. 
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 flxed 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:
