Rhododendron Sargentianum is a member of a group of 
some fifteen species of dwarf shrubby Rhododendrons 
with aromatic leaves, clustered capitulate inflorescences, 
tubular corollas that are usually villous within, short 
included stamens and very short capsules which are 
more or less invested by the hardened calyx. The 
species was discovered by Mr. E. H. Wilson in 1903 near 
Washan in Western Szechuan, when collecting on behalf 
of Messrs. J. Veitch and Sons, and was again met with 
by him, growing on exposed rocks near Moupine in the 
same province both in 1908 and in 1910. ‘The central 
species of the group to which it belongs is A&,
