Misc. USDA views this plant as a hybrid of lance-leaved violet, Viola lanceolata, and small white violet, Viola macloskeyi or Viola blanda. Other experts regard it as a true species.

Most violets are cleistogamous, kleistos, Greek for closed. A cleistogamous flower produces seeds without having produced obvious flowers, as opposed to chasmogamous flowers which open, allowing for pollination. Violets typically produce both types of flowers.
