Hah. Prov. Shinano : Mt. Togakushi {K. Jlatsuokal July 1901; K. 

 Tanaka\ May 1902). 



A rare species; it should be grouped with Viola vaginata Maxim, 

 and V. Matsumurce ]\Iakino, but it is smaller. 



I have named it in honour of Sir. Komesaburu Yazawa, Professor in 

 the Nagano Normal School in prov. Shinano.
