A most distinct species of the series of lepidote Rhododendrons 
which have a conspicuous wax-coating on the under side of the 
leaves. Here the epidermal papillae upon the surface of which 
the wax-granules appear are rod-like and of some length. The 
lepidote indumentum is on the young leaves abundant on the 
upper leaf-surface, on the older leaves-it may disappear alto- 
gether save for a few scales in the groove of the midrib. On 
the under side the scales are always conspicuous and some of 
them are larger than the others. Every scale arises in a pit. 
The pits are somewhat shallower on the upper surface, and those 
on the lower surface are never more in depth than a quarter of 
the leaf-thickness. The pits are lined with wax-papillae and the 
scale has a stout pedicel which is long enough to project the 
upper part of the scale disk outside the mouth of the pit, conse-
