-'hoetes lacustris L. In quantity on the bottom of Llyn Helyg, 

 altitude 600 ft., 1906. This lake, though of considerable extent, 

 does not exceed six feet in depth at any point. The Quillwort and 

 Littorella together form a vast carpet covering acres of the bed of 

 the llyn. The lake is surrounded by fir-woods and it is curious 

 that so prolific and interesting a spot should never have been pre- 

 viously visited by any botanist. This is the only sheet of fresh 

 water of any extent in the county. 



*Pilularia globulifera L. In fair amount about the north-east 

 margin of Llyn Helyg, fruiting abundantly, altitude 600 ft., August, 

 1906, W. £ D. This is a very acceptable addition to the flora, and 

 especially so as I am afraid it must have long been extinct in the
