 CLYDESDALE MOSSES. 



By James Murray. 



The list appended is a resume of the mosses which have 

 been brought under the notice of the Society at meetings and 

 excursions during the last four years. 



It is necessarily far from complete, owing to the short period 

 over which observations have extended, to the small number ot 

 workers in the field, and to the limited district to which the 

 Society is confined in its excursions. Nevertheless, several 

 interesting records have been made, a number of mosses having 

 been found that seem to have been hitherto overlooked in our 

 neighbourhood. 



A considerable number of the commonest species are omitted, 

 as little interest attaches to reports of mosses which are well-nigh 

 universal in their distribution. In this connection mention may 

 be made of the list compiled by Dr. Stirton for the Fauna and 

 Flora of Clydesdale and the West of Scotland (Glasgow, 1876). 



The district covered approximately coincides with that defined 

 by Hennedy in the Clydesdale Flora. It extends up the valley of 

 the Clyde as far as Tinto, and down the firth to Arran and the 

 opposite coasts, taking in the Campsie and Kilpatrick Hills on 

 the north. 



The portion of this district lying nearest Glasgow has naturally 

 been more thoroughly worked than the outlying parts. On this 

 account, and in order to give the list a special local interest, 

 prominence has been given to reports of species occurring within 

 a radius of 20 miles of the city. The more distant parts have 

 only been drawn upon in the case of species which have not been 

 found within the narrower limits. 



The rarer mosses have the names of the finders appended. 

 This is also done when only one notice of the occurrence of a
