This species is most nearly resembling to LJillof>】iyllis rhynchc- 

 carpa Rupr. and, beyond any question, it has close affinity with 

 the latter. But, Callophyllis rhynchocarpa has entire margin for 

 a Ion per distance than it is in the present plant, and toothed or 

 lacinulated portions seem to be mostly limited to upper portions, 

 as I judge from a specimen 01 it collected at the eastern coast 

 of Sakhalin.
