256 BALFOUR—NEW SPECIES OF RHODODENDRON. 
quently the periphery of the disk can grow out as a fringe resting 
upon the papillate epidermal cells of the adjacent lamina-surface. 
The fringe is entire, its cells united throughout their whole 
length and bounded on the outside by a firm regular wall. The 
umbo is often convex at maturity, and its red secretion gives 
a scintillating aspect to the leaf-surface. The scales of the 
pedicels and flower-parts are of the same type but they are not 
partially sunk in pits. 
No other Chinese species with this indumentum has so large 
leaves as has Rh. pachypodum. The name is given in reference 
to the short and stout pedicel. There is another feature in 
the flower region deserving of mention. The umbel is few- 
flowered and apparently only one flower in the umbel sets 
seeds. On one twig I find two capsules, but usually there is 
a solitary capsule on the stout pedicel at the end of the 
flowering twig. The flowers available for examination are un- 
fortunately withered, and the description given above may 
therefore require modification when better specimens are known. 
The most conspicuous feature in the flower is the long lepidote 
style which persists and in fruit is curved downwards from near 
the base. The style which induced the name Rh. longistylum, 
given by Rehder and Wilson to one of their species—perhaps a 
distant ally—is only 2.5-3 cm. long, just about half the length 
of that in our species. 
Rh. pachypodum is a plant of the Tali Range, and might 
have been expected to occur amongst the collection of Delavay. 
But I can find nothing like it, and Mr. Forrest tells me it is a 
rare plant.
