 October 1904 (Veitch Exped. Nos. 3958, 3958% 3959, 3961); vicinity 

 of Tachien-lu 3000-4500 m., A. E. Pratt (No. 58, type of R. Prattii

 (No. 4272, in part; bush 4 m. tall) ; Mt. Omei, June 1904 (Veitch Exped. 

 No. 5142). 



The undescribed fruit of this species is stout, cylindric, 2.5-3 cm. long, 7-9 mm. 

 wide, usually curved, furrowed, 8-10-celled, hairy, very sparsely glandular; the 

 persistent calyx-lobes enclosing the lower half of the capsule; seeds fusiform, 

 3-3.5 mm. long, dark brown. 



This very common woodland species varies considerably in the size of the leaves, 

 in the degree of tomentum on their under surface and in the size of the calyx-lobes 

 which, however, are always ample. In No. 3432 the i)edicels are nearly glabrous, 

 the calyx-lobes are short, and narrow and the leaves closely resemble those of 

 B. Przewalskii Maximowicz. No. 5142 has very glandular pedicels.
