Virts Lasrusca, L. 
Dr. Zxgelmann, ina letter, dated Oct. 15, 1882, expresses great 
doubt of this species being indigenous at Niagara Falls, or 
elsewhere in our territory. A careful re-examination of the 
ground makes it quite certain that he is right. But that the 
plant frequently springs up, spontaneously, near vineyards 
in our vicinity is a matter of frequent observation. 
Vitis cordifolia, Lam., var. riparia, Gray. 
This variety, regarded by Dr. Exge/mann as a distinct species,

the river. It also occurs at Point Abino, Ont. ‘The typical 
V. cordifolia probably does not belong within our limits.
