XV. — A Provisional List of the Hepatic.e of the Hawaiian 

 Islands. By A. W. Evans. 



During the years 18V5 and 1876, Mr. D. D. Baldwin made a 

 systematic collection of the Hepaticae found growing in the Ha- 

 waiian Islands, particularly in the island of Maui. These were sent 

 to Prof. Eaton for determination, and he, in turn, sent many of them 

 to Mr. Austin, w^ho published descriptions of several new species 

 and returned to Prof. Eaton a list of his determinations, including 

 many species previously described. The following list is based 

 largely upon those determinations, but contains in addition several 

 of Mr. Baldwin's species which Mr, Austin did not examine. All 

 other species accredited to the Islands in tlie Synopsis Hepaticarum 

 and in other publications are also mentioned in the list.
