HEPATICAE COLLECTED BY WILLIAM A. SETCHELL 

 IN NORTHERN ALASKA. 



BY ALEXANDER W. EVANS. 



The Hepaticae noted in the following list were collected during 

 the summer of 1899. Most of the specimens came from the island 

 of Unalaska, but a few were gathered on the island of St. Micheal 

 and a few on the mainland, at Cape Nome. In the writer's recent 

 report on the Alaska Hepaticae collected by the Harriman ex- 

 pidition, 82 species are accredited to the Territory. 1 Gymno- 

 mitrium crenidatum Gottsche, a species formerly known from 

 Europe only, has since been added by Herr Stephani;" and, in the 

 present list, Aneura major and Jungerma tin \ia caespiticia are re- 

 ported as Alaskan for the first time. These 3 species increase 

 the total number to 85.
