S.E. Tibet: Tsarong. Salween—Kiu-chiang divide. Forrest 
No. 19,206. July roi. 
Nearest ally perhaps is Rh. trichopodum, Balf. f. et Forrest. 
Like that species it has puberulous branchlets, upper midrib, and 
petiole. Its leaves are larger than in Rh. trichopodum markedly 
reticulate when dry on upper opaque surface and usually cordu- 
late at base. Its scales are more separate below and leave a 
glaucous purple waxy surface between them, which gives a 
like sheen to the whole under surface. The flower has copious 
crimson spots on the corolla. Perhaps only a form of Rh. 
trichopodum.
