Nom. Jap. SaJcaiva-saifthin. 



Hab. Prov. Tosa : Sakawa in Takaoka-gori {T. Maliino ! 1887, April 

 18 and May 9, 15, 1889, June 1893). 



This is commonly found at mountain foot and hills in Sakawa- 

 Tillage and its vicinities in the province of Tosa in Isl. Shikoku, and it has 

 the largest flower among the Japanese species of Asarum. The inner 

 lamella3 of the calyx-tube are arranged longitudinally without being reticulated 

 one another, which never occurs in any Japanese species known till now. The 

 habit of leaves is as that of Asarum Tlmnhergil Al. Br. { = Heterotropa 

 asaroides Morr. et Decne.).
