XV. REPORT ON TWO COLLECTIONS OF 



HEPATIC.^ FROM NORTHEASTERN 



MINNESOTA. 



Alexander W. Evans. 



The two collections embodied in the present report were both 

 made in Cook county, the first by Messrs. MacMillan, Lyon 

 and Brand, in 1901, the second by Mr. Holzinger in 1902. 

 Although these collections contain no new species, they add 

 quite a little to our knowledge of the distribution of Hepaticae 

 in North America. Thirty-two species, all belonging to the 

 Jungermanniacea2, are represented, and the collection of 1901 

 contains in addition a sterile Pellia and a sterile JRiccardia, 

 neither of which can be determined with certainty. So far as 

 can be learned, sixteen of the thirty-two species are here re- 

 corded from Minnesota for the first time, and three of these, 

 Lophozia rutheana, Sphenolobus exsectceformis and Odonlo- 

 schisma macoumi, have not before been reported south of the 

 Canadian boundary. The numbers refer to the specimens in 

 the collection of 1901 ; Mr. Holzinger's specimens, which are 

 unnumbered, are simply designated by his initial ; species new 

 to Minnesota are marked with an asterisk.
