S.E. Tibet. Tsarong. On Ka-gwr-pw, Mekong-Salween 
divide. Lat. 28° 35’ N.. Alt. 13,000-14,000 ft. In Rhodo- 
dendron thickets. Shrub of 5-8 ft. G. Forrest. No. 14,913.

This species belongs toa phylum of Rhododendron in which 
the pedicels, calyx, and ovary are glandular. It is distinguished 
at a glance by the bright rusty-red bistrate indumentum, the 
upper stratum of which is formed of characteristic dendriform 
branched curled hairs which interlock in a loose wool-like 
canopy and seem to be often deciduous leaving exposed the 
under stratum of rosette short-branched hairs. The very young 
leaves seem to have many glands intermixed with the hairs 
of the under stratum. At maturity the midrib is particularly 
glandular. The colour is in the young leaves a yellowish green 
and changes gradually to the rusty colour which is best seen 
on leaves in their second year. The indumentum surface here 
is never shining and the hairs are never agglutinate. 
The species is one of a group well-developed in these N.W. 
Yunnan regions, and finds its nearest allies in Rh. Albertseni- 
anum, G. Forrest and Rh. levistratum, Balf. f. et Forrest.
