21 mm across at widest

Common in woods, in short grass, on roadside banks and stony ground, including high in hills.

Flower diameter c 12-18 mm

ID: Leaf-edge makes clear change of direction at tip rather than being rounded there as in Marsh Violet.  All leaves heart-shaped, about as long as broad, never more than twice as long as broad as in Pansies.  Has basal non-flowering leaf-rosette with flowers arising on side-branches or from buds on roots.  This distinguishes it from Heath Violet, but may be hard to see on poorly-formed plants.  Heath Violet has leaves longer than broad.

Other features: Lower petal white at innermost end, with area of dark vertical veins just below this.  Flower has a long spur which is notched at the end.  Also produces cleistogamous flowers without petals or stamens.  Stipule-teeth hair-like, flexible and spreading out to the side (straight, upright and not so thin on Heath Violet)
