Snow Azalea 



(Evergreen azalea; Mucronatum group) 

 (Although Chamberlain and Rae (1990) retain R. 

 mucronatum (Bl.) G. Don var. mucronatum as a 

 botanical taxon, they note that the plant is "only 

 known in cultivation." They also note that var. 

 mucronatum "may occur in the wild as the albino 

 form of [R. mucronatum] var. ripense." Because 

 of the amibiguity surrounding its origin, the 

 Snow Azalea is accorded cultivar status here as 

 'Mucronatum', and its closely related variants 

 are identified as being in the "Mucronatum 

 group.")
