IV. — Identity of Draba nikoensis Koidz. 



When describing this plant the author compared his new 

 species with D. hirta L. 1 ' It has, however, no close affinity with 

 the latter, and moreover represents no other than a form of D. 

 Sakuraii Mak., which was originally described as D. sinanensis 

 Mak. 2) The identity and relationship of D. sinanensis with D. 

 Sakuraii has been fully discussed by the present writer in vol. xxv 

 of this Magazine,"'' so that no further comment will be made 

 here. 



It is interesting to find this plant in Nikko, for the only 

 locality known had been Mt. Togakushi, in the Province of 

 Shinano.
