 cm. long, tipped with a slight beak. Seeds dark brown, ovate. 



Peking to Hongkong, Kansu to Yunnan. 



Introduced to Japan. Tlie wood is light and tough, used in car- 

 pentry. The flowers and buds yield a yellow dye and the pods an 

 important medicine. The preparation of the dye is very simple. The 

 flowers and buds are baked in an oven until they turn brown, then 

 placed in a pot of cold water and brought to a boil. The liquid is 

 poured into the vats ready for use. The bark, wood and roots contain 

 a purgative property. A fine avenue of Sophora japonica may be seen in 

 the grounds of the Temple of Heaven in Peking. A pendulous form is 

 often planted. 



Propagated by seeds and cuttings. A pound of seeds contains 

 between 3,180 to 4,140 seeds. Germination is slow and uneven.
