The beautiful Rhododendron now figured is a native of 
the neighbourhood of Ta-chien-lu in Western Szechuan, 
where it occurs rather abundantly in upland thickets and 
woods at about 12,000 feet above sea-level. The plant 
from which the material for our plate has been derived 
was raised from seed collected in 1908 by Mr. E. H. 
Wilson when travelling in China on behalf of Professor 
Sargent, Arnold Arboretum, by whom a supply was 
presented to Kew in 1909. There was, however, @ 
previous introduction of this species, also by means of 
seed obtained by Mr. Wilson, but on behalf of Messrs. J. 
Veitch and Sons. The species has reached the stage of 
Aveust, 1915.
