Conservatories 
Following out plans for the improvement of the conservatory 
collections, in the direction of gradually substituting definitely 
planned groups for miscellaneous groups, house plants and in- 
sectivorous plants were installed in House No. 4, and in December 
nine glass aquarium tanks were obtained for water plants. Houses 
rt and 12 were also rearranged, to include citrus and other 
subtropical fruits, Japanese dwarf plants, and other groups. 
Trans parencies.—Additional drawings for transparencies repre- 
senting fossil plants were made by Miss Purdy, eight being nearly 
ready at the end of the year. In this connection I corresponded 
with paleobotanists and visited Dr. Berry at the Johns Hopkins 
University, Dr. Hollick at the New York Botanical Garden and 
Dr. Wieland at Yale, all of whom gave valuable suggestions. 
Herbarium 
Thanks to the energy of Miss Burr and later of Dr. Svenson, 
the former chaotic state of our storage collections downstairs has 
heen largely overcome. 
Among collections acquired during 1930 were the following: 
400 specimens from the Galapagos Islands and 204 chiefly from 
Tennessee, collected by Dr. Svenson; 225 from Honduras, pur- 
chased from W. A. Schipp; 125 obtained by exchange from the 
University of California; 523 Philippine plants purchased from 
Mr. A. D. E. Elmer ; 272 from the state of Washington, purchased 
from Mr, J. M. Grant. 
The old-world herbarium has been separated from that of 
American plants. 
Cryptogamic Herbarium 
Algae, lichens, and bryophytes have now been provisionally ar- 
ranged in the new cases in the basement. Some duplicates of 
mosses have been sorted out. 
Dr. Reed reports that very few additions were made to the 
Herbarium of Fungi during the past year: 26 specimens of higher 
fungi were received from the University of California, on the 
basis of exchange ; three additional fascicles of the Fungi Exotici, 
published by Dr. TH. Sydow, and containing 150 specimens, were 
purchased.
