The manuscript of Ambrosiaceae was finished and was 
delivered to the editor. The manuscript of the tribe 
Senecioneae (except the genus Senecio) is essentially finished 
and is sufficient for another part of North American Flora. 
Work on the tribe Indigofereae of Fabaceae and on the 
following tribe Galegeae is advancing. Only a little work 
was accomplished on the flora of the Rocky Mountains; 
a “Key to the Rocky Mountain Flora” was published 
during the spring and one article in the series ‘‘ Phyto- 
geographical Notes on the Rocky Mountain Region” was 
printed during the summer. 
Dr. Marshall A. Howe, Curator, remained in charge of 
the collections of algae and hepaticae in the herbarium and 
museums. Determination and entry into the herbarium 
of somewhat more than 2,000 field numbers of marine 
algae collected some years ago by Dr. Howe in the Bahama 
Islands has constituted the chief work of the year, and the 
results of this study have been summarized in a systematic 
treatment of the algae of the Bahamas contributed to 
Britton & Millspaugh’s “Bahama Flora,” now in press. 
Papers published during the year include “‘On Some Fossil 
and Recent Lithothamnieae of the Panama Canal Zone,” 
“Tertiary Calcareous Algae from the Islands of St. Bar- 
tholomew, Antigua, and Anguilla,” and ‘‘Dahlias and 
their Culture.” Dr. Howe continued in charge of the 
Garden’s dahlia border, has given three lectures in the 
Saturday afternoon courses, and has continued to act as 
an associate editor of the publications of the Torrey 
Botanical Club and as delegate from the Torrey Botanical 
Club to the Council of the New York Academy of Sciences. 
Dr. Fred J. Seaver, Curator, continued in charge of the 
fungi, which have been installed in their new quarters on 
the second floor of the museum building. Research has 
been continued on the cup-fungi of North America and also 
on certain of the lower fungi causing leaf-spot diseases, 
both preparatory to monographs for North American 
Flora. A chapter on Bahama fungi has been written for
