THE CHARACEAE OF THE ROSSES : 

 WEST DONEGAL. 



BY REV. CANON. G R. BULLOCK-WEBSTER, M.A. 



Last year I reported on the results of a visit to the Fanad 

 Peninsula where I spent a fortnight investigating" the 

 Characeae of the lakes around Kindrum. 



This year I found an opportunity for paying a visit to 

 the Rosses of West Donegal where the many and various 

 lakes seem to offer a very favourable field for the 

 characeologist. 



My headquarters were on the little island of Iniscoo 

 about a mile off the coast, near Burton Port ; and my 

 companion, Bishop Montgomery, himself a keen naturalist 

 and a student more especially of bird life. 



The weather during our week's sojourn (July 26-31) was 

 all that could be desired and we made the most of the 

 opportunity. Iniscoo itself provides a small lake, and 

 this was carefully examined. On the mainland northward 

 we visited (I quote in all cases the nomenclature of the one 

 inch Ordnance Survey) Garry Lough and Sally's Lough, 

 Loughs Waskel and Mullaghderg ; to the southward 

 towards Dunglow, we visited Loughs Leckenagh, Meela, 

 Dunglow, and Adrihidbeg ; and to the south-west of 

 Dunglow we visited L. Nageeragh, the adjacent lough 

 unnamed in the map, L. Beg and Maghery L. This last, 

 and Sally's Lough first mentioned, have cuttings which 

 connects them with the shore and provides admission of 

 sea water at certain states of the tide. For this reason 

 they suggested likely localities for such species as C. 

 connivens, C. canescens and C. haltica which are to be found 

 in brackish waters. But the water proved to be more saline 

 than brackish and seemed to yield little or no fresh water 

 vegetation. 



The result of these explorations can be summed up in a 

 few words. Of the twelve lakes visited nine gave no 

 signs whatever of Chara vegetation. The tenth, the
