Korea. 



Young leaves of this species are occasionally more or less appressed 

 pubescent, as Purdom's no. 376 from Shensi which has some branchlets 

 nearly glabrous and others together with the petioles minutely but densely 

 grayish pubescent with the leaves thinly appressed-pubescent ; Hers' 

 no. 229 from Honan is similar to the latter, but the fruiting specimen 

 (no. 280) from the same locality is perfectly glabrous and a typical C. 

 Bungeana except that the leaves are rather narrower. On vigorous shoots 

 as Hers' no. 1330 the leaves may be scabrid above and more or less pilose 

 beneath, while his no. 411 from the same locality has smooth and glabrous 

 or nearly glabrous leaves. Cowdry's no. 479 and Hers' no. 2169 represent 

 apparently a juvenile form with part of the leaves constricted about the 

 middle into an elongated lanceolate or linear-lanceolate lobe.

 only 1.5-2 cm. in length, only a few at the end of some branchlets being 

 up to 3 cm. long.
