Glabrous liana; stems terete (often faintly quadrangular on drying). Petioles 5-8 mm long; stipules lacking or inconspicuous and early deciduous; blades elliptic to oblong-elliptic, obtuse to acuminate at apex, obtuse to acute or rounded at base, 5-13.5 cm long, 2.5-5.7 cm wide. Inflorescences cymose, axillary or terminal, dichot­omously branched, to 6 cm long; flowers greenish-yellow to olive-green, 10-12 mm diam, 5-parted; sepals semi­orbicular, ca 1 mm long, broader than long; petals ± ovate-lanceolate, 4-5 mm long, blunt at apex, serrate; disk prominent; stamens 3, ca 1.5 mm long, held closely against the 3-sided stigma; filaments flattened, broadened at base; anthers broadly reniform, broader than long, dehiscing by a transverse slit; ovary ovoid; style short, slightly shorter than stamens. Fruits trilobate, shallowly bowl-shaped, to 15 cm wide, pendent at maturity; meri­carps 3, conspicuously flattened, rounded to emarginate at apex, connate 3-5 cm at their bases, dehiscing along a median suture to allow seeds to slowly drift out, the margins thin; seeds 10-14 per mericarp, thin-winged, ca 2 cm long and 2.5 cm wide including wings. Croat 11734, 12622.

Occasional, in the canopy of the forest. Flowers most abundantly from July through August, but also from December to April. Fruit maturity time uncertain.
