58 PROCEEDINGS COTTESWOLD CLUB 1910 



districts investigated by the Club during its stay at Builth. 

 The basis of the flora in each case was ericetal : the divergences 

 from this type were few : the main body of plants seen each 

 day was the same. For instance, after looking at Matricaria 

 suaveolens Buch. by the roadside, a rapidly-increasing Ameri- 

 can alien, we got at once, on Carneddau, into a mass of Viola 

 Riviniana Reichb., Stcllaria graminea L. in a large flowered 

 form which seems common this year, Linum catharticum L., 

 Ulex Gallii Planch., Potentilla ereda Hampe, Alchemilla arven-
