Flowers in each sex usually solitary, sometimes male flowers are in few-flowered racemes. Receptacle pale green, glabrous. Calyx teeth 1.5–3.5 mm long, lanceolate to (narrow) triangulate, erect to reflexed. Corolla 1.5–3 cm long, whitish cream to pale yellow, rarely dull orange-brown with conspicuous green venation, lobes 0.9–2 cm. Stamens 3, reduced to staminodia in female flowers. Anthers in male flowers sinuate, in a globose head. Ovary cylindrical, glabrous. Style in male flowers minning, in female flowers columnar, greenish yellow. Stigmas bulging, greenish yellow. Fruit 8–12 × 3–4 cm, ellipsoid to oblong, when immature green with white longitudinal spots to stripes with waxy bloom, ripe red. Seeds 6–8 × 3–3.5 × 1–1.5 mm, more or less symmetrically obovate, face flat.
