Western Szech'uan: Ching-chi Hsien, uplands, Ta-pao-shan, 
alt. 2600-3100 m., September 15, 1908 (No. 3453; bush 30-80 cm. 
tall, forming thickets, flowers white). 
Very rare in Szech’uan, and only seen on the high mountains separating Wa- 
shan and Wa-wu-shan. 
Our flowering specimens seem to differ at the first glance from the type by 
their depauperate inflorescence bearing only 2 or 3 flowers, but this may be ac- 
counted for by the fact that they represent a second flowering in September; the 
inflorescences with young fruits formed the previous spring, bear many capsules.
