A common and widely distributed species on hills, mountains and in 
forests of Japan. The colour and maculation of the petiole and the colour 
of the spatlie are variable. Leaves either entire or serrate or sometimes 
in the intermediate state; such difference of the leaf-margin is not an 
important character of this species, and this condition also prevails largely 
in some other Japanese species of the same genus. 
There is a robust species on Mt. Imano in the southern part of Isl. 
Shikoku. Its fruit is conical;and berries are large and measure 1-J-l み cm. 
or more across, and scarlet when mature; and the rachis is dark-purple. 
The leaves are entire and pedatisected as those of Ariscema javonicum Bl. 
It may be a new species and I like to give it a new name Ariscema macro- 
car pon mild.
