334) Vitis Coignetii, Polliat ex Planch, in Journ. Vigne Amer- 

 (1883) p. 186. 



var. glabrescens, Nakai. 

 Folia subttis sparsius lanata v. fere secus venas tantum lanata. 

 Nom. Jap. Takeshima-yama-bud5. 



Hab. in insula Ooryongto : in silvis Dodong (Takenoshin Nakai 



n. 4426-8), in rupibus Chagara (Takenoshin Nakai n. 4429), 



in silvis Songosan (Takenoshin Nakai n. 4425), in monte 



400 m. (Tsutomu Ishidoya m 91). 



This is only Vitis in this island. The degree of tomentum is very 



variable in the different individuals. With its tomentose extremities 



on one hand, this approaches to Vitis Coignetii and with glabrous 



extremities to Vitis amurensis on the other hand. Examining many 



specimens collected from various localities, we are unable to discover 



any valid difference between V. amurensis and V. Coignetii except the 



degree of pubescence on the undersurface of leaves, and they come into 



perfect unanimity intercalating the present variety. 



335) Yiola insularis, Nakai sp. nov. 



This is nearest to Viola Kusanoana which is very common in this 

 island and from which is distinguishable by the small flowers. I think 

 this has varied from that by the mutation or by the cross between 

 V. verecunda and that.
