vagans,) flourishes over continuous miles of ground, 

 growing low and stunted when it encounters the 

 sea-breeze, but in sheltered situations attaining a 

 large size. It does not flower until August, and 

 early in September its lovely snowy and pink 

 blossoms cover acres upon acres of barren moor. 

 Within this same formation and district other rare 

 or peculiar plants appear, as Corrigiola littoralis, 

 Elatine Jiexandra, Herniaria glabra, ^Exacwm fili-

Spircea salicifolia. In the vicinity of Bala, North 

 Wales, on the banks of the river Trueryn, which 

 falls into the Dee near that place, this shrub forms 

 a pretty and characteristic vegetation. Except in 

 the moist boggy parts of the principality, it is 

 scarcely indigenous to Britain.
