While it is in many ways desirable that the research 
activities of the members of the Garden staff should be 
given publicity through diverse channels, it is in other 
ways to be regretted that our own publications are not 
able to handle all of our scientific papers. 
My personal research through the year has been directed 
to a continuation of studies on the South American species 
of Siphocampylus and Centropogon, in which notable 
progress has been made, in spite of insufficient material. 
The studies have already revealed a wealth of undescribed 
species in these two genera in the mountains of Colombia 
and Ecuador and serve to illustrate and emphasize the 
great need of further botanical exploration in northern 
South America, a work in which the Garden is already 
actively engaged. 
Besides the Contribution mentioned above, I have 
published during the year, six short articles and have sub- 
mitted several short abstracts to the editor of Botanical 
Absiracts 
Finally, it is a pleasure to record the general improvement 
in the esprit de corps of the entire Garden personnel, due 
to increase in salaries and the reduction in the cost of 
living, and the better condition of our growing plants and 
our material equipment, due to the efficient work of our 
faithful employees, the reopening of conservatory range 2, 
and the increased funds available for maintenance.
