NOTES ON A COLLECTION OF NEW ZEALAND 



HEPATICAE 



BY 



WILLIAM HENRY PEAESON 



Since Archibald Menzies collected Hepaticae in New Zealand in 

 1791 (the specimens are in the Manchester Museum), a large number 

 of species have been added by various collectors and named by 

 Mitten, Stephani, Colenso, and other authorities. These are all 

 enumerated by Stephani in his Species Hepaticarum and Supplement 

 up to 1918. Colenso published as new a great many species in the 

 Transactions of the New Zealand Institute, most of which have been 

 examined by Stephani, and a revision of the same published in the 

 Journal of the Linnean Society for 1893. I have not been able to 

 find that any New Zealand Hepaticae have been published since 1918. 



The present collection was made by Professor Setchell in 1904. 

 Although small, it contains some interesting species and its examin- 

 ation has afforded me much pleasure. There may be errors in 

 judgment, where I have not had the opportunity of comparing the 

 specimens with the original types, but I have been very fortunate 

 in being able to do so in many cases, for the Manchester Museum 

 is very rich in types of New Zealand species from the Carrington 

 and Spruce collections. 



Although Stephani records many New Zealand species from Tas- 

 mania and Australia, he intimates in one of his notes that he is of 

 the opinion that the Hepatic Flora of New Zealand is almost endemic, 

 and with this opinion I agree. 



The type specimens of all species described as new are deposited 

 in the Herbarium of the University of California and duplicates of 

 the same, as far as the specimens would allow division, are also 

 deposited in the Manchester Museum in England.
