W.N.-W.-Yunnan. Mekong-Salween divide. Lat. 28° 12’ N. 
Alt. 11,000 ft. In open cane scrub. Shrub from 2-2} ft. 
Flowers dull soft rose without markings. G. Forrest. No. 
14,268. July rg17. 
One of the most charming forms into which the type of 
Rh. sanguinewm, Franch., diverges on the highlands in the N.W. 
of Yunnan. It seems to have shorter and broader and less 
obovate leaves than others of the series and its corolla forms a 
shallower more open bell. The bright rose-tinting of the corolla- 
lobes which is retained to some extent in the dried material 
is a marked beautiful feature according to Forrest. On p. 80 
the relationships of Rh. sanguineum and its allies are discussed.
