MOSSES OF THE WNION VALLEY, MEEIONETHSHIRE. 



By James E. Bagnall, A.L.S. 



In the early part of October, 1897, I had the pleasure of 

 spending a few days with some friends at Bont Newydd, and 

 during my stay I spent a few hours with them on the beautiful 

 mountain Aran Mawddwy, which would well repay a more ex- 

 tensive visit than time then allowed. We also spent a morning 

 on the beautiful woody slopes rising from the River Wnion to the 

 Bala Road, above Bont Newydd ; here I saw AndrecBa on boulders 

 at about 400 ft. above sea-level. A morning was given to the lanes 

 leading to the '* Torrent Walk," where the mosses on the walls 

 and roofs and waysides were so abundant that we did not reach the 

 specialty of the neighbourhood. An afternoon was given to a visit 

 to the " Precipice Walk," and the lanes in its vicinity yielded quite 

 a wealth of interesting species. On my last morning we paid a 

 short visit to the Estuary and the interesting neighbourhood of 

 Dolgelly, where on stone walls not more than 30-40 ft. above sea- 

 level I saw AndrecBCi petrophila, and A. Rothii in good fruiting 

 condition. I brought home considerable spoils of mosses and 

 hepatics, and am convinced a longer visit and closer attention 

 would yield a still richer harvest.
