Description:

Viola riviniana, the Common Dog-violet, is a species of the genus Viola. It is also called wood violet or dog violet. It is a perennial herb of woodland rides, grassland and shady hedge banks. It is found in all soils except acid or very wet. Although it was in the middle of the forest I'm not sure on the ID. It could also have been a 'lost' cultivated plant
