Notes for Ballard et al. (2023):
Viola fimbriatula is a segregate of V. sagittata.
Viola palmata is further broken down into var. palmata and var. triloba.
Viola primulifolia is listed as not occurring around the Great Lakes, material instead likely being referrable to V. × sublanceolata (V. lanceolata × minuscula).
Viola subsinuata is listed as being endemic to the greater Appalachian region. There is no name to replace it for the entity in the Chicago Region, so the name is preserved for the time being.
Viola vittata is listed as being sometimes mistakenly identified from depauperate V. lanceolata material, but does not occur north of the Atlantic coastal plain.
