Yunnan. Mountains in the N.E. of the Yangtze bend. Lat. 
27° 45’ N. Alt. 10,000-11,000 ft. Shrub of 4-6 ft. Flowers 
crimson? Open thicket. G. Forrest. No. 10,347. June 
1913; No. 11,490. Oct. 1913 
I have not found it easy to discriminate between the two 
species of Franchet, Rh. spiciferum, Franch. and Rh. scabrius- 
. eulum Franch., both of which belong to a series of Rhododen- 
au 
drons with characteristic indumentum. Rh. mollicomum, Balf. 
f. et W. W. Sm. is a very distinct species although in many ways 
like Franchet’s species, but it wants entirely their characteristic 
rough setae and is smooth and soft all over. 
There are two specimens in Mr. Forrest’s collections, both 
from the Chungtien Plateau at gooo-10,000 ft. under Nos. 
12,402 and 12,619, which are also this species I believe. They 
have larger flowers and a more developed calyx, and Mr. Forrest 
describes the flowers as rose or pale rose without markings.
