Taxonomic note Name conserved. Orthographic error: R. lochiae. Royal Horticultural Society (1997)
This attractive and floriferous species has been in cultivation at least since 1939 and is the parent of many hybrids. It was for these reasons that the name has recently been conserved and the original plant described under this name is now R. notiale (see L.A. Craven & R.M. Withers: A second species of Rhododendron (Ericaceae) from Australia, Edinb. J. Bot. 53(1): 27-37, 1996). Royal Horticultural Society (1997)
