REPORT OF THE CHAIRMAN OF THE 
SCIENTIFIC DIRECTORS 
(Received and ordered printed Jan. 10, 1921) 
To THE Boarp or ManaceRs oF THE New York Botan- 
ICAL GARDEN. 
Gentlemen: The Scientific Directors have held their 
regular meetings throughout the year. We have seriously 
missed our colleague Doctor Lee, who has been absent in 
Europe. Among topics receiving special attention are 
plans for pushing work in botanical exploration and for 
developing experimental research on problems relating to 
soils and plant diseases. 
There is an increasing demand through the Torrey 
Botanical Club for a more intensive study of the native 
plants of the local floral region from the standpoint of 
variation, geographic distribution, hybridization, etc., and 
it is hoped we may be able to make further provision at 
the garden for storing and studying the collections re- 
sulting from such work. 
The report of the Director-in-Chief gives a full account 
of the educational, research and other scientific activities 
of the garden during the year and they need not be further 
summarized here. 
Respectfully submitted, 
. A. Harper, 
Chairman of the Scientific Directors.
