Lowland Toothcup is a native herbaceous annual in the Loosestrife family (Lythraceae). It can be found throughout Alabama. Lowland Toothcup occurs in wet, open areas such as pond and lake margins, on the banks of rivers and streams, in wet depressions, and in ditches. It is an annual with a tap root. The stems are erect or ascending, usually branched, green in color, and glabrous. The decumbent stem or lower branches may root where in contact with the soil. Leaves are opposite, sessile or short petiolate, linear to oblanceolate in outline, glabrous, with entire margins. Flowers are solitary and sessile in the axils of the leaves. Each flower is subtended by two small bracts about ½ as long as the floral tube. The floral tube is short and square with 4 triangular green sepals and 4 pinkish petals. The fruit is a capsule.—A.
