Explanatory Note. 



The letters contained in the notes about the distribution of the different 

 species mean the following: 



V R = Very rare 

 R R = Rather rare 



R = Rare 



V C = Very common 

 R C = Rather common 



C = Common 



Usually where localities are cited it means that there is a specimen 

 from that place, but, especially in the case of common plants, they are 

 more widely distributed than the citation to the definite localities would 

 appear to indicate. It is for this reason that the above plan has been 

 adopted. 



For place names see the map at the beginning of this book. As there 

 defined "Montauk" means from the western end of Fort Pond to Great 

 Pond; "Montauk Point" from the eastern edge of Great Pond to the 

 Light house; and the "Hither Woods," as from the very earliest days, is 

 applied to the forested tract west of Fort Pond.
