1907. Knowles & O'Bkien. — Flo? a of Shanid. 193 



country is into the valley of the Galey in the south, where the 

 rocks are Coal-measures, and the valley of the White River, 

 which flows through the shales and grits, in the north. A 

 good deal of it is under grass, but the high ground which 

 forms the watershed is chiefly bog, only remarkable for the 

 plants we did not find on it. We did not see either Drosera 

 intermedia or Rynchospora fusea. The chief species noted 

 were Drosera ang/iea, D. rotundtfolia, /uncus squarrosus, 

 Scirpus ccespitosus, Narthecium Ossifragum, Eriea Tetralix, E. 

 cinerea, Calluna vulgaris, Cai'ex limosa, Myosotis repcns, and 

 Lycopodium Selago. Most of the rare plants of the valley of 

 the White River have been mentioned already. For a great 

 part of its course, as far as and beyond Ballyhahill, the banks 

 are steep and covered with a natural and almost inpenetrable 

 wood. Near Ballyhahill, in a grove of Sallies, the Elecampane 

 grows luxuriantly. Except along the rivers the county is a 

 bleak and treeless waste. 



Several interesting plants grow on the banks of the Galey. 

 Euphorbia hiber?ia is everywhere along its course. At Athea 

 the meadows on either side of the river were covered with it, 

 and we traced it almost to the source on the side of Rooskagh. 



Agtimonia do? at a and Rttbus argentatus are two other plants 

 from its banks. Ulex Gallii, a few bushes of w r hich we noted 

 on the side of the mountain, is a welcome addition to the 

 flora of the county. Rooskagh itself (1,132 feet) was a great 

 disappointment ; we spent a whole wet day on its summit 

 hunting for Empeirum nigrum and other mountain plants 

 without success, nor did we find any plant of interest to 

 reward us. 



But a little to the north of Rooskagh is the Glenastar 

 waterfall, and here, in July, 1905, Mr. Aubrey Gwynn found 

 a very interestiii g plant — Epilobium angustifolium. We visited 

 the spot in August last, when the plant was in flower. It 

 grows in considerable quantity on the northern side of the 

 stream, but only, so far as we could see, in the neighbourhood 

 of the waterfall, and, indeed, this is the only suitable ground 

 for it. Above the fall the stream flows through flat bogland, 

 and we did not look for it there, but we searched the lower 

 part of the stream, and did not find it. There is no reason to
