Review identifications of Viola tripartita 170264
Viola tripartita in the strict sense always has at least some compound leaves or leaves with deep lobes. It has a restricted range, mostly in the southern Appalachians.
The other two species have unlobed and undivided leaves. They are apparently nearly allopatric. See this page (or references below) for their distinguishing characters.

Unintended disagreements occur when a parent (B) is
thinned by swapping a child (E) to another part of the
taxonomic tree, resulting in existing IDs of the parent being interpreted
as disagreements with existing IDs of the swapped child.
Identification
ID 2 of taxon E will be an unintended disagreement with ID 1 of taxon B after the taxon swap
If thinning a parent results in more than 10 unintended disagreements, you
should split the parent after swapping the child to replace existing IDs
of the parent (B) with IDs that don't disagree.
