NOTES ON SOME MOSSES IN NORTHERN IREIvAND. 



BY J. H. DAVIES. 



With the exception of a few gathered in the district of the 

 Mourne Mountains, and in County Armagh, the mosses 

 enumerated in the short list here given, have recently been 

 met with in the course of pleasant rambles in the neighbour- 

 hood of Lisburn. 



Through the long-continued absence of rain during a great 

 part of last summer, some of the deep bogs became so dried 

 up that opportunity was afforded for more patient examination 

 of their bryological productions than could convenientl}^ be 

 given under usual conditions. Thus, species inhabiting such 

 places were detected which else might have remained un- 

 noticed. Of such are Mniuvi stibglobosuvi, Hypntun vernicosum, 

 and H. gigaiitetim, not to mention others. 



For some of the rarer mosses of the north-east of Ireland 

 additional localities are supplied, and as will be seen, the list 

 contains the names of some which do not appear in Stewart 

 and Corry's Flora, nor in the Supplement to that work ; also 

 of some which seem to be new to the Irish Moss-flora. 



Especially gratifying and interesting was it to gather so far 

 north the beautiful Webera Tozen, hitherto known only as a 

 southern species, whose head-quarters are in the regions of 

 the Mediterranean. 



As in some previous bryological notes contributed to these 

 pages, it has been found convenient to follow the nomenclature 

 adopted by Mr. H. N. Dixon in the " Student's Handbook of 

 British Mosses." Mr. Dixon, from whom I have received much 

 kindness and serviceable information, has verified or named 

 for me all doubtful species that from time to time have been 

 submitted to him.
