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 unfrequently underground. The 
Viota 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 Cist1, and made the basis of a new one. Vioxa, 
strictly defined, is almost equally divided between Europe 
and the temperate portion of North America.
