1 894-1 plants of monroe county. 3 



Scope of the List. 



The list aims to include the names of plants which grow without 

 cultivation in Monroe and adjoining counties. While it is believed to 

 be nearly complete as regards Monroe county, it is not claimed to be 

 so for the adjacent counties. 



The list includes phanerogams a ular acrogens. Much 



care has been exercised in the deter of specimens, and all 



those concerning which there have been r« enable doubts have been 



excluded. 



Territory Included. 



The territory included, as seen by the accompanying map, com- 

 prises the whole of Monroe county and parts of Genesee, Livingston, 

 Orleans, Ontario and Wayne counties. The area in general is the 

 lower drainage basin of the Genesee river, with that of Irondequoit

 is designed to be a guide to all parts of the region, locating as it does 

 the roads and streams, and points of especial botanical interest. In 

 lack of any definite geographic boundaries, the outlines of the map 

 were fixed somewhat arbitrarily.

 this way Dr. Dewey examined and re-examined many times the

 The influence which he thus exerted is still perceived by some of the
