Prof. Nakai noticed that his Asarum Sieboldii var. seoulense is conspecifie with 

 Asarum heterotropoidcs Fr. Schmidt when he looked upon the co-type specimens 

 at the herbarium of the Paris Natural History Museum in 1924. Of this he told 

 me when I began my study on the Japanese Asaracece. However, he still claims 

 that A. heterotropoides and A. Sieboldii make the different variety of the same 

 species. A. heterotropoides has more obtuse leaves and more reflexed lobes of 

 perianth than A. Sieboldii, and hairy variety seoulense and glabrescent variety 

 manshuricum make the two extremities of the hairiness of Asarum heterotropoides.
