Kiangsi: Ruling, near a temple, alt. 1600 m., July 29, 1907 (No. 

 i68o). 



This is in every respect a well marked species, which may be related to R. 

 utilis Decaisne or possibly to R. hupehensis Schneider. 



There is a flowering specimen from Szech'uan, collected by Dr. A. Henry in 

 1885-88, No. 5601, the leaves of which resemble those of R. Wilsonii. They have 

 the same shape and serration and the same short petioles. The male flowers, 

 however, have longer pedicels (up to 12 mm.) and closely resemble those of R. 

 utilis. Wilson's Nos. 217 and 649 have the same leaf characters and pistillate 

 flowers with shorter pedicels (5-7 mm.).
