MORE NEW ZEALAND HEPATICAE 



BY 

 WILLIAM HENRY PEARSON 



The following is a list of species, in a further collection from the 

 North Island made by Professor AV. A. Setchell in 1904, arranged 

 according to Stephani's Species Hepaticarum. 



Where the specimens could be divided, a set has been deposited 

 in the Manchester Museum, in England, but the type specimens of 

 the new species are deposited in the Herbarium of the University of 

 California.
