INDEX 
This index has been arranged to serve also as a check list of the 
genera, species, subspecies, and varieties of plants discussed in the 
body of the publication. Accepted names of native browse species 
and genera, both English and Latin, appear in heavy type. Where 
the Latin and English generic names are identical (e. g., Acacia, 
>) 
Rhododendron, and Viburnum) the name is not repeated. 
Where two or more page references are given, any considerable 
discussion of the subject is indicated in heavy type. 
Exotic genera and species are indicated by the mark (+).
