The Rhododendron which we here figure is a Chinese 
species originally described by Franchet from specimens 
collected in Yunnan by Delavay, where it las also been met 
with by Henry and by Forrest. For its introduction to 
European collections horticulturists are indebted to Mr. 
M. L. de Vilmorin, who has raised plants from seed sent 
to him by Ducloux in 1907. The material from which 
our illustration has been prepared was supplied by Mr. 
de Vilmorin from one of these plants, which flowered at 
Les Barres for the first time in the spring of 1910. The 
only species of A’hododendron which resembles £2. spinuli- 
ferum in the peculiarly shaped corolla is R. Keysii, Nutt., 
figured at t. 4875 of this work. So striking is the deviation 
from the normal type of corolla in the genus, that 2. Keysii 
has been treated as the representative of a distinct section. 
In other respects, however, our plant approaches more 
closely to 2. spiciferum, Franch., and £&. scabrifoliam, Frauch., 
Decemser, 1911.
