shorter than the corolla, on erect awl-shaped filaments, with long 

 anthers, of two linear cells opening at the apex. Style simple, linear, 

 longer than the stamens, with an obtuse stigma. 



Habitat. Dry mountainous heaths of Ireland ; frequent in the wild 

 district of Cunnamara, and the mountainous parts of the county of 

 Mayo. 



Shrub ; flowering in July and August. 



This is a beautiful and highly ornamental hardy shrub, frequently 

 cultivated in gardens, especially the very pretty white flowered variety, 

 which seems to have been first found by J. Kenny, Esq., in the county 

 of Mayo, about fifteen years ago, and has since been observed in 

 several parts of Cunnamara. It was at one time supposed that this 

 species was peculiar to Ireland, but it is found, according to Hooker, 

 in the Western Pyrenees, and in Anjou.
