Tentatively going for this taxa. Moist disturbed habitat; glabrous leaves, petioles, and flower stalks; bearded lateral petals; distinctly crenate margins; sepal auricles somewhat prominent but perhaps not as angular as typical of Viola communis.
The big kicker for me is the unusual petal coloration. From my limited experience, V. communis seems more prone to developing unusual flower patterns than other violet species.
Either way, it's probably one of my favorite observations of the season so far!
Seen with @devinmrodgers. KY state record!
Bees were seen but not photographed. Rudbeckia flowers were their favorite to cut in this field.
