Abbreviations. 



I have used the following abbreviations in this list : — 

 JOHNSTON.— Natural History of the Eastern Borders, 1853. 

 THOMPSON. — Catalogue of Plants growing in the vicinity of Berwick- 



on-Tweed, 1807. 

 M.Fl.— Moss Flora of the Eastern Borders.— Hardy, 1868. 

 HARDY, loo. cit. — List of Mosses collected in the Linns. — Hardy, 



Hist, of Berwickshire Nat. Field Club, Vol. xii., p. 448. 

 B.G. — Botanists'. Guide to Northumberland and Durham (quoted by 



Thompson.) 

 W.B.B. coll.— Collection of Mosses by Wm. B. Boyd. 



The localities which are not followed by one or other of 

 the above references are of my own noting. I have, as a 

 rule, only cited one of the recorded localities for each species, 

 but where the only published record is an early one, I have 

 sometimes added a locality of my own observation. The 

 nomenclature and order are those of the " Student's Handbook 

 of British Mosses," ed. ii. 



The additional species noted by me bring the number of 

 recorded species up from 185 to 236, an addition of 50 species. 

 About half of these are merely confirmations of common plants 

 referred to in the earlier works, but not localised for V.C. 68, and 

 the other half new discoveries. A few of the latter are interest- 

 ing additions to the county flora, such as Sjjhagnum medium, 

 Grim,mia Ilartmani, Philonotis capillaris, Bryum, idiginosum,, 

 Eurhynchium, Teesdalei, and Hyp. eugyrium, var. Mackayi. 



South Northumberland. 

 I have not been able to discover any published records 

 from V.C. 67. The list given below consists entirely of the 

 few Mosses noted by me in three days spent at Chollerford 

 on the Roman Wall. They amount to 103 species, a number 

 which would easily be doubled with a little research, although 

 it is improbable that the Moss Flora will be found so rich 

 as that of the Northern part of the county, with the higher 

 altitudes of the Cheviot range.
