 destina, from which it is entirely distinct. 



■f t t Flowers somewhat regular, small, white.

 tenuated into a petiole at the base, rather obtuse, subserrate ;

For excellent specimens of this new Viola I am indebted 

 to its discoverer, Prof. Big e I o iv, who informs me that its 

 characters are very constant.
