INDEX 



This index has been arranged to serve also as a check list of the genera, species, and varieties of plants 

 discussed in the body of the publication. Accepted plant names, both English and Latin, appear in heavy 

 type. Synonyms are shown in ordinary type. Where the Latin and English generic names are identical 

 (e. g., Acucia, Geranium) the name is not repeated. 



Since the publication is not pased, the symbols adopted for the respective generic, specific, and varietal 

 discussions (arranged in the order O, GL, W, and B) are given in lieu of pagination. Italicization of a 

 symbol indicates that the genus, species, or variety referred to is not written up separately but is given 

 subordinate treatment under another heading.
