from that island, whose fern flora is the richest in the world, 
and these have been found to include a considerable number 
of species new to science. While in Jamaica, Professor Un- 
derwood collected a number of living plants for the conserva- 
tories and also made arrangements with the officers of the 
Public Gardens and Plantations there, to ship to the Garden 
a large number of living plants of which we had hitherto no 
satisfactory representation. 
r. MacDougal spent parts of February and March in 
company with Mr. Frederick V. Coville, Chief of the Division 
of Botany of the U.S. Department of Agriculture, at the 
request of the Carnegie Institution, in determining the most 
desirable site for the new Desert Laboratory of that institu- 
tion which has since been successfully established at Tucson, 
Arizona. During the trip he secured a considerable number 
of cacti and other succulents for the conservatories. 
Dr. M. A. Howe was absent for about two months, in May 
and June, investigating the seaweeds of Porto Rico, of which 
a very large collection was obtained, and their study has dis- 
closed a great amount of additional information relative to the 
algz of the West Indies. 
Professor F. E. Lloyd, of the Teachers College, accom- 
panied by Mrs. Lloyd, explored the island of Dominica, 
leaving New York early in June and returning about the 
firstof September. About two thousand herbarium and mu- 
seum specimens were obtained, which greatly increase our 
representation of the flora of the Windward Islands. 
Mr. Geo. V. Nash, accompanied by Harry F. Baker, spent 
August and part of September on the island of Haiti, and 
obtained a valuable collection of living plants, museum and 
herbarium specimens, of a flora of which our previous repre- 
sentation was very meager. They succeeded in penetrating 
into the interior of the Black Republic, reaching parts of it 
that had not previously been examined by botanists, and 
many of the plants obtained by them are of great interest. 
I made two trips to the island of Cuba, one in March, ac- 
companied by Mr. J. A. Shafer, and the other in August and
