Liana. Stipules laciniate, inserted obliquely on the branchlets just below the articulation of the petiole. Leaves sometimes also associated with subopposite or even subalternate ones, shining on the upper surface, elliptic to elliptic-oblong, 9-15 by 4.5-8 cm; base cuneate; apex acute, sometimes obtuse; margin remotely crenulate; nerves 5-7 pairs; petiole 4-6 mm. Inflorescences axillary, paniculate-cymose, sometimes branched from the very base and then seemingly more than one in a leaf-axil. Peduncles usually short. Bracts triangular, c. 1 mm long, laciniate, short-fimbriate, or erose on the margin, with filiform or laciniate colleters inserted at the base inside. Pedicels 5-6 mm, with elastic threads shown on breaking. Flowers greenish yellow. Calyx almost divided to the base, lobes very broad-ovate or-obovate, ⅔-1 mm long, obtuse or rounded, or slightly acute at the apex, erose or slightly laciniate at the margin. Petals elliptic, oblong, or obovate-oblong, 3 by 1.5-1.75 mm, obtuse, ± entire, with distinct 5 or more longitudinal veins slightly elevated on the outer surface when dry. Disk fleshy, flat, suborbicular, slightly concave at the central part, c. 1.5 mm ø, c. 0.5 mm high, the basal part slightly extended outward into a narrow, thin rim. Stamens 3, c. 0.5 mm; anthers transversely dehiscent. Pistil slightly emerging from the disk. Ovary 3-celled. Ovules 2 in each cell. Fruit globose, 4-5 cm ø, pericarp 3.5 mm thick, the inner surface with irregular meshes. Seeds suborbicular, ± planoconvex, c. 2.5 mm ø.
