Western Szech’uan: Wa-shan, thickets, alt. 2600-3300 m., 
October 1908 (No. 1341; bush 5-6 m. tall); same locality, woodlands, 
alt. 2300-2800 m., June 1908 (No. 3429; bush 3-5 m. tall, flowers red) ; 
same locality, thickets, alt. 2600-3000 m., June 1908 (No. 3430; bush 
6 m. tall, flowers white); Mupin, woodlands, 2500-2600 m., October 
1910 (No. 4258; bush 2-4 m. tall); Mt. Omei, woodlands, alt. 2600 m. 
(No. 4267; bush 3-4 m. tall). 
The undescribed fruit is stout, cylindric, 1.2-2.5 em. (usually 1.8 cm.) long, 
furrowed, densely covered with brown bristly hairs; seeds dark, shining brown, 
oblong, 3-4 mm. in length. This species which is rather rare is easily recognized 
by its setose branches, petioles and inflorescence. The corolla varies from pure 
white to crimson. No, 3429 is much less bristly than the usual form and shows an 
approach towards R. pachytrichum Franchet, which is the species most closely 
related to it.

Western Szech'uan: Wa-shan, thickets, alt. 2500 m., June and 
November 1908 (No. 1353, in part; bush 3-5 m. tall, flowers flesh- 
pink, spotted); Mupin, woodlands, alt. 2300-2600 m., June 1908 
(No. 1353, in part; bush 3-5 m. tall, flowers white with red blotch); 
same locality, October 1910 (No. 4264; bush 3 m. tall); without precise 
locality, alt. 3300 m., May 1904 (Veitch Exped. No. 3952, type). 
This is a rather rare species, easily recognized by its thick leaves narrowed to 
the base, shining green and rugose above, covered below with loose red-brown to- 
mentum, and by its woolly pedicels and minute calyx. The fruit is similar to 
that of R. Wasonii Hemsley & Wilson.
