Closely resembles C. reiusus, but differs from it by the much shorter 

 petioles and minutely serrulate leaves. There is another specimen of this 

 genus in the Tokyo herbarium, which is labelled " Koshu : Giokuzan, Mai., 

 1910, China." It is closely allied to our species, and may be regarded as 

 identical with ours. The genus exists in North America, China and Japan 

 (BENTH et HOOKER Gen. PI. II. p. 677). Four species including the present 

 one are known.
