Mr. I. F. Holton in 1854 and presented by him to Dr. Torrey, 
and a small lot brought back by Professor ee F. Kemp in 
1885, contained in the same herbarium. he collections ob- 
tained during the present expedition have made the representa- 
tion of the Bermuda flora at the New York Botanical Garden the 
best in the world; a nearly complete duplicate set of the her- 
barium specimens has been deposited at the Academy of Natural 
Sciences in Philadelphia. 
Attention has been given to the study and collecting of all 
land plants, cryptogams as well as phanerogams. 
To Mr. Benjamin D. Gilbert’s ‘Revision of the Bermuda 
Ferns"’ published in 1898,f we have added no species. 
Mrs. Britton’s work on the mosses has added greatly to the 
known species growing in Bermuda. 
An account of the ner was published by Professor A. W. 
Evans in 1906; one species has since been added. 
Dr. Marshall Avery Howe of our staff visited Bermuda in the 
summer of 1900, and made large collections of marine algae, but 
other visits at different times in the year are necessary to make 
his knowledge of the algal flora measurably complete. There is 
little known as yet about the microscopic algae.

species of fungi, but there are very many more. Mr. and Mrs. 
Bernard O. Dodge collected some 40 species in the summer of 
1911. Our second trip of 1912 was especially organized for the 
study and collection of these plants by the presence of Dr. 
Seaver, who obtained over 150 species, which are now being 
studied. 
Biologically, and as regards origin, interest centers on the 
species native to this little archipelago, so far separated from
