This is a very different plant from P. Souliet with which 
Diels identified it. Rh. Souliet, Franch. is a Szechwan plant 
and is not recorded from Yunnan. Rh. jucundum is a plant 
restricted so far as we know to the eastern flank of the Tali 
Range in western Yunnan. Apart from the indumentum 
features, which are easily observed, the flower offers two 
distinctive characters: the corolla here has not the wide open 
form so marked in RA. Souliei, and the style is quite glabrous. 
The western flank of the Tali Range contributes three 
plants to Mr. Forrest’s collection under Nos. 11,577, 11,578, 
and 11,601 which belong to the series including Rh. jucundum, 
and are probably new species.
