Western Szech'uan: Ching-chi Hsien, Ta-hsiang-ling, thickets, 
alt. 2000-2300 m., May 16, 1907 (No. 3424, type); without precise 
locality, alt. 2000-2500 m., May 1904 (Veitch Exped. No. 3966). 
This is a distinct species easily recognized by its foliage and long slender pedi- 
cels. It is allied to R. insigne Hemsley & Wilson which is a much more vigorous 
growing species with thick coriaceous leaves, larger flowers and villose stamens. 
R. argyrophyllum Franchet and its varieties with which this new species may 
be compared has rather different shaped leaves, clothed with white tomentum 
below.
