SOME HEPATICAE OF THE APOSTLE ISLANDS. 
CHARLES E. ALLEN, 
Assistant Professor of Botany , University of Wisconsin. 
The following is a list of Hepaticae collected on two of the 
Apostle Islands, Lake Superior, between the 18th and the 28th 
of August, 1902. One day was spent on Presque Isle, the rest 
of the time on Mjadaline Island. Though this list by no means 
pretends to be complete, it is of interest to note, as showing the 
need of work with this group of plants, that of the twenty- 
one species enumerated below, six, 'Nos. 5, 6, 8, 13, 18 and 19, 
have not previously been reported to occur in Wisconsin. 
Where the specific name used differs from that given by 
Underwood in the sixth edition of Gray’s Manual, the latter is 
added as a synonym. “M.” indicates the collection of the 
species in question on Ma d aline Island, “P 1 .” its collect ion on 
Presque Isle.
