Western Szech'uan: south-east of Tachien-lu, woods, alt. 3300 
m., June 1908 (No. 3415; bush 1-4 m. tall, flowers bright rosy-red); 
Mupin, woodlands, alt. 3000-3300 m., October 1910 (No. 4261; bush 
3-4 m. tall); without precise locality, alt. 1300-2300 m., May 1904 
(Veitch Exped. No. 3978).

or shortly acuminate and cuneate at the base, and ovoid acutish winter-buds 
distinguish this from the closely related R. oreodoxa Franchet.

Yachou Fu, western Szech’uan, who on several occasions during the year 1908
