INDEX OF SPECIES. 



VOLUME I. 



Varieties are printed as species. When a species name of adjective form is 

 followed by two or more genera or subgenera of differing gender, there are 

 placed after it the appropriate endings in the order — masculine, feminine and 

 neuter. All numbers refer to pages. Name of genera, subgenera and species 

 regarded as synonyms are, when possible, printed in italics.
