My specimens of this plant are from Aizu in the province oflwashiro, and 

 from Omiya near Tokyo. 



This species differs chiefly from S. nipponicum^ Maximowicz (Mel. Biol., 

 vol. ix., p. 17.), 1st., in the leaflets of the lowest leaves not bejng oblong and 

 acute at both ends; 2d., in the calyx-teeth not being unequal; 3d., in one of the 

 mericarps being abortive. In the plants kept in the Botanic Garden of the 

 Imperial University and also in those naturally growing at Omiya, the last 

 character has been always observed.
