578 Evans: REPORT ON THE HEPATICAE OF ALASKA 
The present report is based on Professor Frye’s collection, but 
it reviews also what is known from other sources about the He- 
paticae of Alaska and compares the species found in the territory 
with those occurring in other parts of the world. In addition to 
the seventy species represented in the present material, forty other 
species have been reported from Alaska. Five of these reports, 
however, were based on incorrect determinations or insufficient 
evidence, so that only thirty-five of the species can actually be 
accredited. The total number of species now known from Alaska 
is, therefore, 105. This number will probably be more than 
doubled when the flora has been more thoroughly explored. 
BIBLIOGRAPHY 
In the writer’s report on the Hepaticae of the Harriman Expe- 
dition the literature of the Alaskan species is reviewed up to the 
close of 1900. Since that time a small collection of species has been 
reported upon by the writer, and another small collection by 
Howe, while a few additional species have been recorded by K. 
Miiller and Stephani. The more important papers dealing with 
Alaskan species or containing scattered references to them are the 
following, only those which give actual new records being included:

July and August, 1891. Bull. Torrey Club 19: 239-249. 1892. 
A list of thirteen Hepaticae from Alaska is given on pages 246 and 247, six of the 
species being reported for the first time.
