Hah. Prov. EtcuCt : Mt. Tateyama (7?. Yatahe and J. Matsumnra ! 

 July 24, 1884); Prov. Eikuchu : Mt. Iwate (77. Sahnrcu \ herb. Imp. 

 Mus. Sept. 1890). 



This differs from the type principally by having the thicker glabrous 

 and impressed-veined leaves and larger flowers. It was also collected on 

 Mt. Iwate in the })rovince of Pvikuchfi by Dr. Kazuma Jo, in 1901, and 

 the name Tahane-s^miire, or alpine Violet, was proposed by him, and it 

 is cultivated bv Mr. Bunsai loki in Nikko.
