den. It lists the trees and shrubs growing here in the open 
in the summer of 1942, and includes a map to help the 
visitor find particular plant groups. The letters and nu¬ 
merals set in brackets after each generic description are 
keyed to the map. The word “nursery” indicates that some 
representatives of the genus are still of small size, hence are 
accommodated for the present in our nurseries. 
ARRANGEMENT OF COLLECTION 
In general, the collection is arranged so that the plants 
of each genus are grouped. When an individual kind 
needs a special environment, it may be located away 
from the group to which it belongs. Additional plantings 
of many species have been installed for purely ornamental 
effect. Thus the “collection” of deciduous barberries is lo¬ 
cated at 6J, while the evergreen barberries, which are more 
tender, are planted in the sheltered courtyard of Con¬ 
servatory Range I (8E). In other parts of the grounds, se¬ 
lected barberries are used as hedges and for other deco¬ 
rative purposes. 
The Garden area consisted originally of native wood¬ 
land. Today, it includes about 40 acres, known as the 
Hemlock Forest, which is carefully preserved in its natural 
state. In all parts of the grounds, magnificent examples of 
native trees are to be found and the collections of planted 
material are interspersed among these. 
The older collections of deciduous trees, including the 
oaks, beeches, and magnolias, are located in the northern 
part of the grounds and to the east of the Bronx River.
