This is found wild commonly in the northern part and 

 sometimes in the central part of Japan. According to my 

 opinion, this may be the original plant from which many of 

 our cultivated forms ( Prunus serrulata Lindl.=P. donarium 

 Sieb. -P. pseudo-Cerasus (2. hortensis .Maxim.) are derived. Ii 

 differs from the tender Prunus Jamasakura Sieb. (=P. pseudo- 

 Cerasus Lindl. ". spontanea Maxim I b\ being much robuster 

 in the Bize oi various organs. II Fr. Schmidt's variety, cited 

 above, was proved to be the same with my "borealis," it 

 should be replaced with var, ft sachalinensis (Fi Schm.) 

 Makino.
