Viola septemloba Leconte. Section: Nosphinium. Subsection: Borealiamericanae. Southern Coastal Violet. Phen: Chasmogamous flower Feb-May; chasmogamous fruit Apr-Jun; cleistogamous fruit July-Oct. Hab: Longleaf pine sandhills, other sandy pinelands and secondary habitats derived from them. Dist: Se. VA south to s. FL, west to LA, mainly on the Coastal Plain.

ID notes: This heterophyllous species is occasionally confused with V. sagittata (another member of the Sagittata group) and homophyllous cut-leaved V. brittoniana; the ranges of these three converge on the Coastal Plain, but the local and regional distributions of V. brittoniana and V. septemloba are virtually non-overlapping. This differs from V. brittoniana in having subsucculent glabrous gray-green foliage, the earliest and latest leaf blades undivided, cut leaf blades mostly pedately divided with the terminal lobe commonly undivided and broader and longer than the other lobes, the chasmogamous peduncle held above the leaves, often larger flower, and larger brownish-black seeds; and from V. sagittata in its subsucculent gray-green foliage, commonly more elongate and more numerous lateral lobes, typically larger flowers, and larger brownish-black seeds.
