'Rhododendron planetum' from the website Trees and Shrubs Online (treesandshrubsonline.
Probably a hybrid of R. decorum (Subsect. Fortunea). The type of this species was raised from Wilson seed number 1882 (perhaps a mistake for 1782) at Caerhays. the seed is supposed to have originated near Tatsienlu (Kangding) in W Sichuan though no matching wild collected specimens are known. This species should not therefore be accorded any formal status. Royal Horticultural Society (1997)
