Philip Evans collected this species on the Dulongshan , the divide between the Salween in China and the Taron in Burma , at the relatively low altitude of 650m. in 1997.
R. Seinghkuense is closely related to R. edgeworthii, has similar attractive foliage, but differs in its yellow flowers and having no scent. It is proving hardy in Philip's garden in Cornwall. It is listed in Glendoick's catalogue.
