This species represents on Bei-ma-shan the Mekong-Salween 
Rh. sigillatum, Balf. f. et Forrest. A much larger plant than 
that, more fragrant and with smaller pointed narrower leaves, 
leaves not so glossy above as in Rh. sigillatum. ‘There are minor 
differences. Note the calyx wants the large lobe so marked in 
Rh. sigillatum—and the ovary is differently punctate. The 
underleaf indumentum hairs are like but not quite the same.
