Nom. Jap. Maruha-sumire. 



This species is not uncommon. It differs from Viola Keiskei Miq. 

 (Ld. Prol. Fl. Jap. p. 85; Maxim, in Mel. Biol. IX. p. 734.), principally by 

 the habit of being estoloniferous. In Tokyo, it is commonly found. 



Viola Keiskei Miq. is probably a form of V. hirta Linn.
