The American Violets have received particular attention 

 from Mr. Nuttall, in his " Genera of North American 

 Plants;" in which work he has enumerated twenty species, 

 and in a great measure recast their characters. It is observed 

 by that botanist, that all those of America, like the canina of 

 these parts, continue through the summer to produce flowers 

 without petals, which are succeeded by fruit ; and that in 

 all the caulescent species, with the exception of the anoma- 

 lous concolor, the fruit so produced is generally situated 

 near to the root, and not unfrequentljr underground. The 

 Viola striata, which flowers in the vicinity of Philadelphia 

 till June, begins to bear apetalous flowers in July, in con- 

 sequence, as Mr. Nuttall expresses it, of the elevated tem- 

 perature. He is of opinion that the genus, as now defined, 

 requires reduction; and that it should be removed from the 

 order of Cisti, and made the basis of a new one. Viola, 

 strictly defined, is almost equally divided between Europe 

 and the temperate portion of North America.
