 New and rare Australasian mosses, mostly from Mitten's herbariui 



The rich material in Mitten's herbarium contains a large 

 number of undescribed species, many of which are vaHd for publica- 

 tion. I propose in this paper to describe some of these from the 

 Australasian region, together with some from the same region 

 which have come to me from other sources, a few notes on other 

 rare species being added. I hope later to describe further species 

 from other geographical regions. 



I have to thank Mrs. N. L. Britton and the authorities of the 

 New York Botanical Garden for both the material on which most 

 of these species are based and for further specimens needed to 

 elucidate them; and also to the authorities at the Kew Herbarium 

 for facilities for studying the material there.
