Lagtang is a large woody vine with a corky, gray bark and white wood. Stems are sometimes 10 centimeters thick, longitudinally wadded, porous, with stout, smooth branches. Leaves are ovate or ovately-cordate, 10 to 20 centimeters long, with pointed or tapering apex and rounded or nearly heart-shaped base, smooth above, hairy on the nerve axils beneath, and 3-nerved from the base. Petioles are 5 to 15 centimeters long. Flowers are yellowish, sweet-scented, 6 to 7 millimeters across, crowded on 3- to 4.5 centimeters long, pendulous panicles. Fruit is a drupe, nearly spherical, about 1 centimeter in diameter when dry, smooth and hard.
