There was, in addition, a considerable amount of replacement 
planting and filling in of shrubbery, together with additions to 
existing collections. These are noted in the list of plant accessions 
printed elsewhere. 
Labeling and Record Work 
The number of labels made was as follows:

The consignment numbers 21-1 to 21-34 were assigned during 
the year to 245 different plants, which were added to the synoptic 
collections. The annual Seed List was prepared, printed, and dis- 
tributed to foreign botanic gardens. Cultivated plants were col- 
lected and mounted, and all new plantings were recorded and many 
service labels made, especially in the rock garden and in the propa- 
gating houses. A revised list of all the genera in the Garden has 
been prepared, containing many additions to the one for the pre- 
ceding year. For two weeks during the summer Mrs. Burdick 
assisted the genetics department with their records. 
A new style of label was adopted for the woody plants. It is 
of lead, attached by screws to a three-foot steel standard, which is 
sunk into the ground about a foot and a half to prevent its being 
disturbed. The standard is given a coat of tar to protect the part 
that is in the ground from rust. About one hundred of these labels 
have already been placed. 
Specimens of each of the varieties of the Boston Fern (Nephro- 
lepis) grown at the Garden were collected, dried, and mounted 
under the direction of Dr. R. C. Benedict. Two duplicate her- 
barium sets of Nephrolepis varieties were compiled and sent out as 
exchanges with other institutions. 
An exhibition illustrating the evolution of plants was shown at
