Plants of Fishers Island 



Charles C. Hanmer 



The following list of Plants of Fishers Island, New York, is 

 the result of about thirty years' collecting on the Island. 



The last seven years plants have been collected for the Her- 

 barium of the Brooklyn Botanic Garden. Almost all of this col- 

 lection is now deposited in the above Herbarium. 



The list contains about five hundred species and I feel that it 

 is fairly complete, although I am sure that more species will be 

 added from time to time. 



Since 1926 a number of species have become very rare, or have 

 disappeared entirely from the Island's flora. This refers largely 

 to swamp plants, which could not survive the severe draining, wnth 

 the resultant growth of briars and small trees. 



Much credit is due my friend, Mr. Charles A. Weatherby, 

 Senior Curator of the Gray Herbarium, Cambridge, Massachu- 

 setts, for his careful determination of the species unknown to me. 



I wish to express my appreciation of the kindly interest and 

 many courtesies accorded me, both from individuals and the Island's 

 officials. Without these courtesies the project could not have 

 reached its present degree of completeness. 



The nomenclature used is that of the Seventh Edition of Gray's 

 Manual, except for a few more recent names.
