Taxonomic note (incl. R. heftii Davidian) Royal Horticultural Society (1997)

White-flowered forms with leaves more or less glabrous beneath have been referred to R. heftii Davidian. This species is closely allied to R. campanulatum and treated by some as a variety of that species. Natural hybrids between R. wallichii and R. arboreum are found in cultivation.
