Sand Violet (Viola affinis) was named and described by James Eatton Le Conte, an American botanist, in 1828. It has kept this name since, but has at some point been considered a subspecies or variety of Viola sororia. Whether a distinct species or not, this species can hybridize with the other making it difficult to identify. This plant is a member of the Violet Family (Violaceae).
