A CHECK-LIST OF PLANTS MENTIONED IN 
THE ARNOLD ARBORETUM BULLETINS 
N OCTOBER, 1914, we published a list of plants mentioned in 
I the Bulletins of Popular Information issued by the Arnold Arbore- 
tum up to that time. 
The present list includes almost all plants mentioned in the Bulletins 
from their beginning, on May 2, Ig11, to the last number issued July 
26, 1919. The list of October, 1914, is, of course, entirely revised, 
corrected to date, and incorporated in this list. 
Mr. E. H. Wilson, Assistant Director of the Arnold Arboretum, 
has read this list in proof. For this kindness we wish to express our 
thanks and our appreciation of the moral support implied. 
We who have worked on this list (and the work has not been easy) 
are again impressed by the value of the work being done by the Arbore- 
tum; in the introduction and testing of new varieties from different 
parts of the world; in rescuing from oblivion many native plants of 
limited distribution; in testing and pointing out the most valuable 
varieties of common plants for garden use; and in fostering our inherited 
love for plants as part of the natural landscape. It is a work which 
must constantly increase in value as the trees and shrubs planted there 
grow older and show their value or lack of value more clearly. .
