THE HEPATICAE OF FISHER'S ISLAND* 



Alexander W. Evans 



Fisher's Island lies in the eastern part of Long Island Sound. 

 Although belonging to the State of New York, it is less than 

 three miles from Connecticut and is therefore much closer to 

 the New England coast than to any part of Long Island. Its 

 total length is about seven miles and its greatest width about 

 a mile and a half; much of the island, however, is less than half 

 a mile wide. The highest elevations are about one hundred 

 feet above sea level, and the slopes are mostly gradual. 



A few wooded areas of limited extent, a few small swamps and 

 bogs, and a few ponds with sandy or peaty shores afford 

 favorable habitats for the Hepaticae; but most of the island, 

 even where not under cultivation, is too dry and too well drained 

 to meet the special requirements of these plants. It is not 

 surprising, therefore, that the liverworts are rather scantily 

 represented. 



The following list ot species is based on two collections, the 

 first made by the writer during the summer of 1916, and the 

 second by Mr. Roy Latham in June, 1924. The records based 

 on Mr. Latham's specimens are indicated by his initials.
