Discussion | Typical Vicia acutifolia has four leaflets. Populations in the northern part of its range in Georgia and South Carolina sometimes have six somewhat broader leaflets, which may indicate intergradation with V. caroliniana (D. Isely 1990). Vicia acutifolia differs from V. floridana in its longer fruits, flowers, leaflets, and inflorescences. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
