Liana, shrub (or slender tree with scandent branches); branches purplish brown or cinereous, smooth or strongly lenticellate. Petiole 3-10(-12) mm long, slender, canaliculate; blades chartaceous or thin-coriaceous, brownish or olivaceous when dried, slightly glossy above, elliptic or ovate-elliptic, (4-)5-10(-15) x (1.5-)2.5-5(-7.5) cm, margins entire, sinuate or crenulate, often remotely dentate near the apex, apex acuminate, the tip glandular, base acute to rounded; primary vein prominent on both surfaces, secondary veins 4-6 per side, arcuately ascending, flattened or slightly prominulous above, prominent beneath, tertiary veins reticulate, nearly flattened above, prominulous beneath. Inflorescences axillary, solitary or paired, 2-11 cm long; peduncle 0.6-3 cm long; bracts ovate, ca. 1 mm long, acute, fimbriate, cinereous-puberulent, like the bracteoles and flowers; bracteoles 0.5 mm long, deltoid, acute, fimbriolate; pedicels slender, 1-2 mm long; buds globose. Flowers (0.6-)1.5-2.7 mm diam., fragrant; sepals deltoid to semiorbicular, acute, mostly entire, 0.35-0.5 x 0.3-0.5 mm; petals white, cream, or purplish white, fleshy, oblong to elliptic, (1-)1.2-1.6 x 0.5-1.2 mm, entire, apex rounded; disk (0.4-)0.6-1 mm wide, 0.1-0.2 mm high; filaments ligulate, 0.3-0.4 mm long, anthers 0.2-0.3 x 0.4-0.5 mm; ovary 0.3-0.5 mm diam., style 0.1 mm long, stigmas forming a minute, capitate, triangular shield. Mericarps elliptic or slightly obovate, 3.5-6 x 2-2.5(-4) cm, ca. 3 mm thick, obtuse or slightly emarginate at apex, pericarp thin-coriaceous with fine, densely, flabellate-costate veins, the veins copiously anastomosing, 0.2-0.4 mm thick; seeds with embryoniferous part coriaceous, ellipsoid, 20-26 x 7 mm, and wing membranous or coriaceous, the basal part to 8 mm long, flange to 5 mm wide or inconspicuous.

Liana or slender tree with scandent branches. Leaves with the petiole 3-9 mm. long, the blade ovate-elliptic or elliptic, acute to rounded at the base, gradually short-acuminate or cuspidate at the apex, entire or crenulate-undulate at the mar-gins, 5-12 cm. long and 2-5 cm. broad, chartaceous, the costa prominent on both surfaces. Inflorescences solitary or aggregated in clusters of 2-4, 2-11 cm. long. Flowers 2-2.7 mm. in diam., often minutely cinereous-puberulus on all exterior sur-faces; sepals deltoid to semiorbicular, subentire or erosulous at the margins, 0.3-0.5 mm. long and 0.4-0.7 mm. broad, submembranous or papyraceous; petals oblong to elliptic, entire or distally erosulous, 1-1.7 mm. long and 0.6-1 mm. broad; disc undulate and slightly thickened at the margin, 0.12-0.2 mm. high; filaments of the stamens 0.3-0.4 mm. long, slightly broadened at base and apex, the anthers about 0.2 mm. long and 0.4 mm. broad; ovary 0.4-0.5 mm. in diam., the ovules 2 per cell, collateral; style 0.1-0.3 mm. long, the stigmas forming a minute, capitate shield, obtuse or faintly emarginate, often obscure. Fruits often 5-10 per inflorescence, the mericarps elliptic or slightly obovate, obtuse or rounded or faintly emarginate at the apex, 3-4.5 cm. long, 2-2.5 cm. broad and about 3 mm. thick, the pericarp thin-coriaceous, conspicuously flabellate-costate without, smooth within; seeds 2 per mericarp, the embryoniferous portion ellipsoid, the wing oblong, 4-5 mm. long and 2-3 mm. broad distally, gradually narrowed toward the base, extended distally into a narrow, thickened flange.
