Glabrous twining woody vines; leaves opposite, or rarely ternate, their bases connected by a stipular line, the very small stipules deciduous; flowers large, yellow, in axillary and terminal nearly sessile cymes, the pedicels scaly-bracteolate. Calyx deeply 5-parted, the segments dry, imbricated. Corolla funnelform, with 5 broad lobes imbricated in the bud.

Stamens 5, inserted on the tube of the corolla; anthers linear-oblong. Ovary oblong, 2-celled; style slender or filiform, 4-cleft, the lobes stigmatic along the inner side; ovules numerous in each cavity, on linear placentae. Capsule elliptic, flattened contrary to the partition, septicidally dehiscent, the valves boat-shaped, 2-cleft at the summit; seeds several in each cell, flattened, winged. [From the Italian Gelsomino, the Jessamine.]
