In the original list of plants 1208 species and varieties were re- 

 ported in Monroe county. In the other counties represented in the 

 list 106 species were reported which, up to that time, had not been 

 reported in Monroe county. Of these 106 species, 11 are now re- 

 ported as growing in Monroe county. 



The total number of species and varieties reported in the Monroe 

 Co. Flora, including the list of 1896 and the present one, is 1584. 

 Total number for Monroe county, 1387.

Authorities. — In arrangement and nomenclature this list follows 

 the plan of the list published in 1896, using as its standard of authority 

 the sixth edition of Gray's Manual of Botany. For new species not 

 mentioned in the sixth edition, the seventh edition of Gray's Botany 

 is followed except for the Crataegus, in which Dr. Charles S. 

 Sargent, Director of the Arnold Arboretum is accepted as authority. 



Typography and Reference Marks. — Each species, variety or 

 marked form regarded as an established member of our flora is given 

 a catalogue number. Those without numbers are not considered 

 fully established. 



Heavy-faced type indicates species believed to be indigenous. 

 Names of introduced species are printed in capitals, as are, also, the 

 common or popular names. 



Parentheses following catalogue names enclose the names used in 

 Gray's fifth edition. 



Brackets indicate that the enclosed matter is the designation 

 given in the Illustrated Flora of the Northern States and Canada by 

 Britton and Brown. 



The name of the discoverer of a plant new to our district, or of 

 a new station for a rare or scarce plant, is given in italics. 



In the present list, the genera are given the same number and 

 follow the same order as in the old list. New genera are inserted in 

 their proper order and, to prevent confusion, are lettered, as 34a, etc. 



The list of 1896 closed with the number 1359. All numbers 

 beyond that in this supplementary list denote new species and 

 varieties. Where new stations are given for rare or scarce plants, the 

 number given in the original list is retained.
