Leaves alternate, 3-foliolate; stipules linear, 1.5–5 mm long; petiole 3.5–8.5 cm long, with a pair of glands at base; petiolules 1–3 mm long, distinctly articulate; leaflets obovate to elliptical, 3.5–12 cm × 2.5–7.5 cm, base cuneate to obtuse, apex acuminate or obtuse and mucronate, glossy at both sides, glaucous beneath. Inflorescence a terminal cyme, 10–many-flowered, often with a tendril in place of the terminal flower; peduncle 3–20 cm long. Flowers bisexual or functionally unisexual, regular, 5-merous, glabrous, whitish to greenish; pedicel 10–20 mm long; hypanthium shallowly cup-shaped or nearly flat, c. 5 mm wide; sepals ovate, 6–10 mm long, apex obtuse to acute; petals oblong, 5–8 mm long, apex acute; corona white, with tube 1–1.5 mm high and threads 3–7 mm long; stamens fused at base for 1–1.5 mm, sometimes with 5 small teeth alternating with the 6–10 mm long filaments; ovary superior, ellipsoid, 2–3 mm long, with stipe up to 1 mm long, 1-celled, styles 3, almost free to over halfway fused, 2–3 mm long, stigmas globose.
