Plant Notes:Twin-Flowered Bindweed is a native herbaceous vine in the Morning-Glory family (Convolvulaceae). It is found primarily in the northern half of Alabama. Twin-Flowered Bindweed occurs on streambanks, along lake margins, in low fields, along wet roadside ditches. It is a perennial from a creeping rhizome. The stems are up to 12 feet in length and climb by twining. The stems are green or reddish brown in color, glabrous, and round in cross section. Leaves are alternate, petiolate, triangular-ovate to sagittate or hastate in outline, glabrous or slightly pubescent on the under surface, with entire margins. Both stems and leaves release a white latex when damaged. Flowers are solitary or rarely paired from the axils of the middle and upper leaves. Two large bracts enclose the developing flowers. The bracts are inflated and their margins overlap for at least half their length. The corolla is funnelform and white or pinkish in color. The fruit is a capsule with 2-4 seed. Until recently this species was treated as a variety of Calystegia sepium or Calystegia sylvatica.—A. Diamond
