The Zanthozylum here figured is a native of Japan, 
which is known in collections of hardy shrubs as 
Z. planispinum. It is, however, doubtful how far it is 
entitled to rank asa species apart. It is one of the series 
of forms to be met with in Japan and Corea which 
extend thence throughout China to Northern India, and 
which are so intimately related that some authors regard. 
them as belonging to the Indian Z. alatum, Roxb. But 
while from the botanical standpoint it may be possible 
or even necessary to adopt this view, it is one that from 
the cultural point of view is distinctly inconvenient.
