 Of this plant there are numerous varieties ; some of which 

 are found in their native woods, others the effect of cultiva- 

 tion. Of the former, the most remarkable is one with from 

 10 to 20 stamens, found by Pursh in the vicinity of Phila- 

 delphia, confirming the opinion, that Azalea (excluding A. 

 jirocumbens ) and Rhododendron should form but one genus.
