subvernicosis viscidis, corolla pallide rosea extus pilosa dis- 
tinguenda 
E. Upper Burma. Wulaw Pass. Valley of Naung Chaung. 
II,000-12,000 ft. On open ridge amongst several of scrub 
rhododendrons. Flowers rose-pink with a dark-red patch at 
base of corolla. Leaves glandular. F. Kingdon Ward. No. 
1g06. 27.8.14. Very late for a rhododendron. 
This species resembles most nearly Rh. pholidotum, Balf. f. 
et W. W. Sm., from the eastern flank of the Tali Range. From 
it and from all others in the Heliolepis series (see p. 113) it should 
be distinguishable by the glutinous upper surface of the leaves— 
Mr. Ward makes special reference to the glandular leaves, but 
it is a feature that is not conspicuous in dried material—and by 
the corolla, which is pilose as well as lepidote on the outside. 
I do not discover any special glands on the leaves. There are the 
lepidote scales which become full of red secretion as they olden 
and might be the organs which cause the stickiness. This 
would not be a common phenomenon on the leaf in species of 
rhododendron, although the scales on the ovary frequently seal 
together by their secretion the surface of the corolla-tube in 
dried specimens. Mr. Tagg tells me that he has failed so far to 
obtain evidence that there is natural exudation from the peltato 
scales. He suggests that exudation is probably always the 
result of pressure from the outside. If this be so some other 
origin for the stickiness of the leaf must be searched for in 
Rh. oporinum.
