plants that are of particular interest to botanists were 
grown. Among these were several forms of Onagra. 
To realize the definite plans of another year more ground 
is needed, and I am pleased to report that according to your 
direction preparations have been made to almost double the 
area of the experimental garden. 
A greenhouse is being devoted to the needs of the experi- 
mental work. The seedlings of various species of Chicorium, 
Hibiscus, Althaea, Verbascum, etc. are grown here during 
the winter and spring months, making such development 
before they are transplanted that they blossom in the field 
the first season. Various plants utilized for student research 
during the winter are, as far as possible, grown in this house. 
Students and Investigators 
The list of students here given is composed mainly of the 
following classes: (1) investigators holding scholarships at 
the Garden; (2) research students in botany registered at 
Columbia University but working in part at the New York 
Botanical Garden; (3) students registered only at the Garden 
and pursuing their studies under the direction of various 
members of the Garden staff. 
A considerable number of these students have come more 
or less under my supervision. In considering the various 
problems of student research, I have had the helpful and 
hearty cooperation of Dr. R. A. Harper, Professor of Botany 
at Columbia University, who is present at the Garden a 
part of each week, and of Professor William J. Gies, head of 
the Biochemical Department of Columbia University, who 
has during the present academic year been at the laboratories 
one afternoon each week for consultation. 
Two theses for the degree of A.M. were completed by 
students of the laboratory during the past year: one by Mr. 
Bristol on “The Starches of Drug Plants,” and one by Miss 
Topp on “Variegation in Miscanthus.” The student re- 
search in plant genetics with which I am especially interested 
pertains chiefly to the following plants; several varieties of
