The specimens from the Yu tai shan, Honan, differ from typical R. 

 banksiopsis in the suborbicular to broad-ovate leaflets not exceeding 1.5 

 cm. in length, in the few-flowered corymbs and in the very short 

 pedicels, and resemble in these characters R. Giraldii Crep., but they 

 have the large broad bracts, glabrous inflorescence and the texture and 

 color of the leaves of R. banksiopsis. Purdom's no. 1119 is a peculiar appar- 

 ently abnormal form with an extremely large and loose inflorescence 

 measuring about 20 cm. in diameter.

Meyer's no. 1365 is the only specimen of this widely distributed and 

 variable Rose I have seen from China; its stem and branchlets are densely 

 bristly; the leaves are 5-foliolate with the leaflets gland-dotted and glabrous 

 beneath except scattered villose hairs on the midrib; the solitary sub- 

 globose to globose-ovoid fruits are borne on glabrous pedicels about 1 

 cm. long.
