Viola riviniana Reichenbach

Flora Europaea           This species easily can be confused with the closely related Viola reichenbachiana. However its flowers are much larger (25-35 cm long instead of 10-20 cm) its flowering period also much late (May instead of March-April) the petals usually have not a darker spot at the base above the whitish unguicula, and the spur is whitish and pointing upwards (not darker than the corolla and straight or pointing downwards). Also the habitat of riviniana seems to be in wetter places from the valleys and damper grasslands inside the forests and in their immediate vicinity.
