species), in healthy condition. They should, therefore, be 
renewed by layering or else be replaced. 
In the following enumeration, the writer has largely de- 
pended on the information found in Mr. Lucius D. Davis’ 
volume on ‘“‘ Ornamental Shrubs” as well as on other rec- 
ognized authorities and nursery men’s catalogues, supple- 
menting this by his own personal studies in the field. 
An appropriate classification of shrubs from the decora- 
tive point of view is difficult, if at all possible, since foliage, 
flower and fruit combine in making decorative value. We 
have therefore chosen a mixed alphabetical and botanical 
scheme, grouping together the seven or eight families which 
furnish the bulk of ornamental shrubs, and following these 
groups by a merely alphabetical list of the single genera 
containing ornamental shrubs. Shrubs which come from gen- 
era containing tree species have for the most part been dis- 
cussed in pages 213-322. The numbers in parenthesis 
preceding the species nam2 coincide with those of the 
species described in the following pages.
