ovary pale greenish white basally, purplish distally, ovoid, 6-angled, 5.5–10 mm;

stigmas erect, divergent-recurved, distinct, purplish abaxially, sessile, almost linear, 6–10 mm, ± equaling ovary, ± not fleshy, very slightly widened basally.

baccate, rosy red to purplish, fragrant of ripe fruit, ovoid to somewhat pyramidal at summit, strongly angled, 2–3.5 × 1–3 cm, very juicy at maturity.
