Viola subsinuata

Viola subsinuata is a perennial that produces purple flowers in the spring. It is superficially similar to Viola palmata, and it can be distinguished by its earliest flowering leaves being divided and similar to later leaves (unlike V. palmata, which has undivided early leaves and divided later leaves).[3]

This species has a complicated taxonomic history, including much nomenclatural confusion and misidentification. The exact geographic boundaries of this species is poorly understood. A recent study indicates that it likely includes cryptic taxa.[2]
