184 THE AZALEAS OF NORTH AMERICA 



Three forms are represented in the colored plate with pink, yellow and orange 

 flowers. They are called double-flowered A. mollis, but are probably hybrids of 

 R. gandavense and R. Kosterianum. I have seen neither plants nor specimens of 

 these double-flowered forms. 



Wilson has based the name R. mixtum on the double-flowered Azalea rustica 

 flore-pleno, but we may include under this name all the different forms probably 

 of the same parentage as given by Wilson.
