Lett — Census Report on the Mosses of Ireland.

J. B. Duncan, and J. Owen, who have rediscovered many of the rarer plants in 

 Mayo, Kerry, and Cork. 



The last recruit to take to "moss-tramping" in Ireland is James Dick 

 Houston, who has made a good beginning by discovering Amblystegium Kochii 

 in Co. Londonderry, a species not before recorded as Irish. 



In the forty-three years that have gone by since David Moore's 

 " Synopsis of the M osses of Ireland " was published, many species new to 

 Ireland have been discovered by various botanists, the records of which 

 are scattered through a number of publications, some of which are not 

 easily accessible. I subjoin a list of these one hundred and eighteen mosses, 

 which may be found useful : —
