 Henry so identifies this. But in Japan Siing-yang is Celtis 

 iniiku or EJirctia sen'ata. Another name given by the 

 Pentsao is ||[ -^ /jv (Liang-tzii-mu). According to the Erhya^

 proportions, growing in Kiangsi, bearing a small edible fruit 

 called ^ ^ 1^ (Tung-ch'ing-kuo), and having a reddish
