The leaves of this species are very variable, and there are several varieties (see 
Seringe and Bureau, l. c.). 
This tree is common everywhere in the warmer parts of China, and in Hupeh 
and Szech'uan it is abundant. In Japan I saw it only as a planted tree in one or 
two localities and I do not think it is genuinely wild anywhere in Japan. When 
allowed to develop it forms a tree 16 m. tall with a trunk 2 m. or more in girth; 
the bark is gray and smooth; the branches are widespreading and form a broad 
rounded crown. Birds are very fond of the fruits, which when ripe are bright 
brick-red and conspicuous. The Chinese name for this tree is Kou-shu and the 
bark is used for making string and also for making the famous leather paper 
(P’i-chih) of western China. Some account of these industries will be found in my 
A Naturalist in Western China, II. 74 (1913). :
