In Korea variety inermis is very widely cultivated and its dried 

 fruits are used for medicine. They have peculiar flavour and are vei y 

 sweet as if they were dipped in Sugar. Chung-chong (or Chu-sei-do 

 by Japanese) prefecture is famous by having good garden varieties. 

 The wild form or the type of variety spinosa is undoubtedly native in 

 Corea. It makes a small low bushes along river sides or over rocky 

 hills. One introduced in Tokyo during the feudal age exists in the 

 botanic garden of Tokyo Imperial University. It is now a big magni- 

 ficient tree. Zizyphus sinensis, Lam. may be identical with the present 

 species ; but if PERSOON is right, it must have pubescent branches and 

 acute serrations.
