Western Szech'uan: Wa-shan, thickets, alt. 2G00-3300 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 cm. (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. 



Group c. 



Leaves with a brown or brownish tomentum covering the whole under surface,

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

 same locality, October 1910 (No. 4264; bush 3 m. tall) ; without precise 

 locahty, 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.
