Acanthopanax spinosum does not occur in China; what has been con- 

 sidered to be that species represents the following two distinct species. 



1. Acanthopanax Hondae Matsuda in Tokyo Bot. Mag. xxxi. 333 (1917). 



Differt ab Acanthopanace koreano quo valde affine, umbelhs breviradiatis, flonbus 

 minoribus, foliis grossius serrulatis. Hoc etiam Acanthopanacem villosulum accedit 

 sed foliis subtus non villosis disco viride exquo distinctum.
