Western Hupeh: Fang Hsien, woods, alt. 2500 m., May 1907 
(No. 509, in part; bush 6 m. tall, head 4 m. through, flowers rose with 
dark blotch); Hsing-shan Hsien, woods, alt. 2000-2500 m., May 1907 
(No. 509, in part; bush 6 m. and more tall, flowers rose-pink with dark

Exped. Nos. 17, 2537); without locality, A. Henry (Nos. 5285, 6914). 
This species has larger flowers and leaves and grows to a greater size than any 
other species found in western Hupeh. It is very common in the woods throughout 
the north-west parts of the province, but is rare south of the Yangtsze river. Its 
short pedicels and larger, differently shaped flowers distinguish it from its near 
relative R. calophytum Franchet.

3000 m., June 1908 (No. 1367, in part; bush 6 m. tall, flowers rose-

The species is common in the forests of western Szech'uan, usually forming & 
tree and growing to a larger size than any other Rhododendron found in that —— 
The bark is cinnamon-red passing to pale brown with age. The long scarlet Lr 
add greatly to the beauty of the flowers which are borne in large loose trusses. 
species is very constant and we can find no variations beyond those of size. A picture 
of this tree will be found under No. 0265 of Wilson's collection of photographs.
