Nom. Jap. Sahurai-so (nov.). 



Eah. Prov. Mino : Foot of Mt. Ena {H. Salmrai ! July 27, 1903). 



This grows in the shady forest in middle Japan, having the habit 

 of the aphyllous Burmannia, and undoubtedly it is a rarest species. I 

 have named this species in honour of Mr. Hanzaburo Sakurai, a botanist 

 in the Imperial Household Museum of Tokyo, who discovered and collected it 

 and generously sent me specimens of this most interesting species.
