A distinct species amongst Rhododendrons which have a 
white persistent favose sa telomanietai on the under side of the leaf, 
The feature catching the eye in the dried specimens is that of 
the persistent dried leaf-bud scale-leaves bracts and leaf petioles 
clothing the old branches, all more or less sticking together by 
the viscid excretion of the setulose glands. These glands occur 
on every part of the shoot. The actual secreting gland-area is 
oblong or club-shaped at the end of a longer or shorter stalk. 
The longer ones are like setae and there are all lengths down 
to almost unstalked glands. The surfaces of the pedicels and 
calyx are made strigillose by them. On the under surface of 
the leaf they are not obvious, being buried amongst the lanate 
hairs—but they are present in numbers. On the upper surface 
of the old leaf there remain but a few scattered glands. The 
hairs of the tomentum of the leaf start as pluricellular pedicels 
which gradually lose themselves in many twisted thick-walled 
threads branching freely and interwoven, the ultimate branches 
having a pointed end. 
The flowers for examination have not been of the best. It 
is possible that we have two species here, and that Nos. 13,244, 
13,551, and 12,592 should be separated from No. 12,944.
