 GENERAL COMPARISON. 



Fortunately for the comparative study of our flora two lists of 

 plants have been published, covering territory both east and west 

 of this area. 



The "Plants of 'Buffalo and Vicinity" was published by the 

 Buffalo Society of Natural History under the authorship of Dr. 

 David F. Day. The list was not confined to any particular territory, 

 but was extended from Buffalo east and south so as to include fields 

 of botanical interest which the Society had studied For example, 

 the swamp at Bergen, in the eastern edge of Genesee County, is 

 included, although it is fifty miles from Buffalo. This swamp is only 

 twenty miles from Rochester, not far from the line of Monroe County,
