eight. Stamens numerous, with slender awl-sliaped filaments and 

 roundish anthers, of two kidney-sliaped lobes. Styles numerous, 

 feathery, with white shining silky hairs, much lenglheued out as the 

 seed ripens. 



Ilabital. — Not uncommon in the alpine districts of England, Scot- 

 land, and Ireland. 



Petennial ; flowering in June. 



TJiis is an extren)ely beautiful and delicate alpine plant, its large 

 white flowers elegantly bending over its mat of numerous dark leaves, 

 are very ornamental in its large spreading tufts. It is perhaps more 

 frequent in the alpine districts of the Coniinentthan with us; and this 

 species and D. intpyrifoUa, found in Greenland, having the leaves entire, 

 and not crenated, are the only known species of the genus, and there 

 are some doubts if the latter is more than a variety oiD. octopefala. It 

 is an extremely pretty garden plant, but requires a northern exposure, 

 and a sandy or gravelly soil.
