Plant Notes:Chapman’s Arrowhead is a native herbaceous perennial in the Water-Plantain family (Alismataceae). It can be found in the southern-most counties of Alabama. Chapman’s Arrowhead occurs in shallow water along the margins of ponds and streams, in swamps and bayous, in cypress ponds, and in wet roadside ditches. It is a perennial from a thick rhizome, lacking stolons or corms. The leaves are submersed or emersed. Submersed leaves are phyllodial (a flattened leafstalk lacking a blade) and up to 1 cm in width. Emersed leaves are petiolate, erect, linear to oblanceolate in outline, and entire. The petiole is triangular. Flowers are produced in 1-12 whorls in panicles. The lower 1-2 whorls of flowers are pistillate with staminate flowers located above the pistillate. Each pedicellate flower has 3 white petals, 3 green recurved to spreading sepals, and numerous pistils or stamens. The filaments of the anthers are pubescent. The fruit is a beaked achene with entire wings. This species is sometimes treated as a variety or subspecies of Grassleaf Arrowhead (Sagittaria graminea Michaux).—A. Diamond
