Bordering the east of the Mino-Hida plateau in the main land (Honsiu) 

 of Japan, the Hida range^^ runs from north to south crowned with many 

 high peaks. The most important of ^' the snow mountains " as they have 

 been called by Dr. J. Eein-^ is Mt. Shirouma in the province of Shinano 

 which lies in latitude 36° 38' north and in longitude 137° 45' east. 



It attains the height of 3040 m. and the great drifts of snow are found 

 throughout the year along its valleys. I may add, it is here, in these 

 valleys, that the evidence of the former existence of 'glaciers has been 

 lately discovered by Dr. N. Yamazaki.^^ 



An opportunity was afforded me during the last summer to spend a 

 few days in this region and the following is offered as a contribution to 

 the botany of this mountain. My collection is yqyj limited however and 

 more important additions are to be expected from the future explorers of 

 this interesting district. 



The basal region. 



The so-called diluvial plain (according to the recognisance of Imperial Geological 

 Survey) is traversed by a number of rapids. The plants here met with are
