This rare Araliaceous species differs principally from Acanihopanax 

 Eleutlierococcus (Maxim.) Makino, in the glabrous and hypo-glaucous 

 leaves and the absence of awls in them, and by having usually a smaller 

 number of flowers in each umbel. 



I have now followed H. Harms (A. Engler und K. Prantl's Die 

 naturlichen Pflanzenfamilien III. Teil, 8. Abteilung, Araliacee) in the 

 reducement of the Eleutlierococcus to the Acanthopanax.
