him, and I have put their study and arrangement in the 
hands of Mr. C. B. Robinson, who has been serving for part 
of the time as a resident research scholar. In addition to or- 
ganizing the material sent in by Mr. Williams, and arrang- 
ing it together with other collections from the Philippines, 
Mr. Robinson has entered upon the work of compiling a 
catalogue of the Philippine flora, based in part on the speci- 
mens and in part on the literature of the subject. 
Dr. D. T. MacDougal, Assistant Director, spent parts of 
January and February in the southern part of the valley of 
the Colorado River, and on the northeastern coast of Lower 
California, securing a considerable number of the very inter- 
esting plants of this little known region, a large number of 
photographs and some herbarium specimens. 
I explored subtropical Florida, accompanied by Mrs. Brit- 
ton and by Dr. Marshall A. Howe, Assistant Curator, during 
parts of March and April, in continuation of work previously 
done in that region by Dr. John K. Small, Curator of the 
Museums, and Mr. Geo. V. Nash, Head Gardener, and Dr. 
Howe and I visited the island of New Providence, Bahamas, 
in April, with Dr. C. F. Millspaugh, Curator of Botany in 
the Field Columbian Museum; my stay on New Providence 
was only for two days at this time, but Dr. Howe and Dr. 
Millspaugh conducted an exploration by means of a sloop 
from New Providence northwestwardly to the western Ba- 
hamian cays, and thence to Miami, Florida. The results of 
this Bahamian exploration showed that our knowledge of this 
archipelago was still very incomplete, and in my report on 
this work I recommended that we organize a detailed botani- 
cal survey of the Bahamas. It became possible for me to 
follow up this recommendation by visiting New Providence 
again during parts of August and September, where I was 
assisted by Mrs. Britton, and by Mr. L. J. K. Brace, a resi- 
dent botanist; a large collection was made at this time which 
has since been somewhat critically studied, and proves to 
contain many species of interest and of novelty. The 
Bahamian exploration was further continued by Mr. Nash,
