ENUMERATION OF THE SPECIES 141 



cultivated in several of the London nurseries." Loddiges states under A. calen- 

 dulacea cuprea, which possibly belongs to this species, that it was introduced in 1806 

 by John Lyon. It must have been in cultivation in Europe before 1812, for I have 

 little doubt that Loiseleur's description and figure in the Nouveau Duhamel 

 represents this species, though he himself identifies it with Azalea canescens Michx. 

 by quoting that name as a synonym. The colored plate in Nouveau Duhamel well 

 shows its difference from R. canescens in the dense flower-cluster, the bright rosy- 

 pink corolla, its wide limb and short tube furnished with conspicuous glandular 

 hairs, the comparatively short stamens and the bluish green leaves. Loiseleur's 

 figure and name, however, have been entirely overlooked by later authors, and 

 after Pursh had described it as A. canescens, the species was not mentioned again, 

 until Porter described it in 1889, clearly pointing out its difference from R, nudiflorum 

 and from R. calendulaceum; but he also referred it to Azalea canescens Michx., 

 naming it R. canescens (Michx.). As a distinct species it was recognized by Small, 

 who described it in 1914 as A. prinophylla in the North American Flora, overlooking 

 the name A. rosea, which is not enumerated in the Index Kewensis nor mentioned 

 in any systematic work after 1812.
