8 p 1^ '\^ l^ I 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 Curasao 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 extent 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. Volumes 2 to 10. Volumes 11 to 13. Volumes 14 and 15. Volume 16. Volumes 17 to 19. Volumes 20 to 34. Myxomycetes, Schizophyta. Fungi. Algae. Bryophyta. Pteridophyta and Gymnospermae. Monocotyledones. Dicotyledones. The preparation of the work has been referred by the Scientific Directors of the Garden to a committee consisting of Dr. N. L. Britton, Dr. M. A. Howe, and Dr. J. H. Barnhart. Dr. 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 more parts will be required for each volume. A limited number of separate parts will be sold at $2.00 each.
