with the cooperation of Mr. R. S. Williams, administrative 
assistant, and other collaborators, finished and sent to press 
the first part of the volume of Norra American Fiora 
devoted to mosses, and accomplished much preliminary 
work on the two parts which are scheduled to succeed it. 
Mrs. Britton prepared a series of articles on “Wild Plants 
Needing Protection,” which appeared, with the addition of 
colored plates, in several issues of the JouRNAL of the Garden, 
and continued her studies on West Indian mosses, partly 
with the cooperation of Dr. A. Leroy Andrews, who com- 
pared specimens with and made notes on type specimens in 
herbaria of northern Europe as an aid to a more accurate 
determination of the West Indian collections, which are 
constantly being increased by further additions from Cuba, 
Jamaica, Porto Rico, and other islands. 
In addition to my curatorial detail and routine I con- 
tinued monographic work in connection with NorrH AMER- 
IcAN Fora, particularly on the family Ericaceae. I also 
devoted some time to a continuation of my studies on the 
flora of the southeastern United States, particularly to the 
floras of Texas and Florida, and completed my studies on 
the plants collected by me in tropical Florida in 1911. 
I spent about five weeks, in November and December, 
exploring and collecting on the Miami limestone region of 
tropical Florida, and on the Florida Keys at points from the 
Upper Sand Keys to Key West. 
Respectfully submitted,

Iead Curator of the Rigas and Herbarium.
