service in bringing together so many kinds of plants which may 

 here be conveniently compared and examined as to their adapt- 

 ability for decorative use. 



In addition to the systematic collections there are many groups 

 of shrubs and many kinds of trees planted in various parts of the 

 grounds. It has been the aim to place along the roads and paths 

 many different kinds of trees in order that all may be impressed 

 by the beauty and variety of arboreal vegetation. The species 

 used here are also plainly labeled. 



Active steps are now being taken to increase the collections of 

 hardy woody plants by the addition of species and varieties not 

 already represented. With adequate facilities these collections 

 can be much enlarged, thus greatly enhancing their educational 

 value. 



In the following enumeration the trees and shrubs are arranged 

 by families, and these in botanical sequence so as to express 

 plant relationship.
