Male flowers: pedicels 1 mm long; sepals (4)5, 1–2 × 1–1.5 mm, strongly imbricate, ovate, obtuse to subacute, pale green; disk glands 5, minute, free, rounded, ± smooth; stamens (4)5, 0.5 mm long, ± free, anthers 0.3 mm long, longitudinally dehiscent.
Fruit 1.5–2 × 2–2.5(3) cm when dried (3–4 cm in diameter when fresh), 3-lobed to subglobose, smooth when fresh, yellowish-green; exocarp papery; mesocarp spongy or corky; endocarp crustaceous.
