‘TREES 
Since September I have been occupied with the trees in the 
Garden. With the cooperation of Dr. Gager, Dr. Graves, Dr. 
Reed, and Mr. Doney, a Guide to the trees in the Botanic 
Garden (Guide No. 13) was prepared and published in the 
January, 1942, Recorp. We have about 130 genera of trees 
with more than 500 species now growing in the Garden; of these 
about 100 are Conifers. Genera of which we have ten or more 
species represented are willow, poplar, birch, oak, magnolia, 
apple, prunus, maple, and ash. Dr. Reed reports that we have 
about 18 varieties of Japanese flowering cherries. With many 
of our trees yet small we still have room for them. In future 
years it will be increasingly a question which trees to eliminate 
in order to have room for the most desirable ones. 
SHRUBS 
Mr. Doney reports that the collections of trees and shrubs 
have been augmented—new species added and old declining 
plants replaced. Among the new plants were Actinidia chinensis, 
Deutzia Veitchii, Magnolia cordata, and Daphne mezereum var. 
alba. Many groups are now occupying all their space and we 
must plant new species on the border mound or elsewhere or 
limit ourselves to the most distinct forms. Many new labels 
were placed; petty vandalism, combined with carelessness, makes 
labelling a constant problem. Hanging wooden labels have not 
proved satisfactory on shrubs with numerous, thin branches, 
such as Spireas; in these cases we are returning to the use of 
upright metal labels. 
In October Mr. Doney spent a week at the Arnold Arboretum, 
studying shrubs with particular attention to Barberries, Crab- 
apples, and Junipers. Some of their genera, such as Tripetaleia, 
Ostryopsis, and Pyracomeles, we do not have; we hope to add 
them to our collection soon. Mr. Doney collected seed of 
several uncommon species, particularly of Berberis and Aesculus. 
Part of our nursery was replanted and the space between 
rows increased so the rototiller could be used for cultivating. 
We have about 700 shrubs in the nursery now, including about 
100 species and varieties not yet on the grounds.
