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

with the following sequence: 
Volume 1. Mycetozoa, Schizophyta, Diatomaceae. 
Volumes 2 to 10. i 
Volumes 20 to 30. Dicotyledones.

wood and N, L. Britton.

R. Barnes and John M. Coulter of the University of Chicago, Mr. Fred- 
erick V. Coville of the United States Department of Agriculture, Pro- 
fessor Edward L. Greene of the United States National Museum, Pro-

ory committee.
