Similar Species: The leaf shape of the Early Blue Violet is extremely variable. The lobes vary in width, length and number and a few leaves may not have any lobes at all. All lobes are wider than in either Birdfoot Violet, Priarie Violet, or Coast Violet. The lobes of Arrow-leaved Violet (if present) are confined to the base of the leaf and the leaf itself is elongate and narrow.
Comments: Three-lobed Violet (Viola triloba) and Stone's Violet (Viola stoneana), previously considered to be good species, are now treated as synonyms of Early Blue Violet.
