Robert B. Faden in Flora of North America (vol. 22)
Herbs, annual, with long-trailing, decumbent shoots. Leaves: blade linear-oblong to linear-lanceolate, 1.5--7 ´ 0.2--1 cm, glabrous. Inflorescences terminal and in distal leaf axils; cymes 1-several, 1-flowered, solitary or fascicled. Flowers bisexual, radially symmetric, 1 cm wide; sepals 5--6 mm; petals purplish lilac or purple to pink or white, 5--8 mm; stamens 3; filaments bearded; staminodes 3. Capsules (4--)5--9 mm. Seeds 2--6 per locule, 1.6--3 mm, faintly ribbed. Flowering fall. Roadside ditches and swales, margins of lakes, creeks, rivers, swamps, bogs, swamp forest, and other aquatic habitats, often growing in water; introduced; Ark., Fla., Ga., Ky., La., Md., Miss., N.C., Oreg., S.C., Tenn., Va., Wash.; Europe; native, Asia. I agree with C. P. Dunn and R. R. Sharitz (1990) that this species is still expanding its range since its introduction early this century.
