Berry 14.4–26.0 mm long, 12.5–19.00 mm in diameter, widely ellipsoid to ovoid, greenish yellow with white spots, becoming soft at the base at maturity. Seeds ca. 10, 5.0–6.1 mm long, 2.1–2.7 mm wide, 1.3–1.9 mm thick, widely elliptic in outline, acute at both ends, reticulate-foveate with each face marked with 12–24 foveae.
