Female: tube 0.3–0.5(0.8) mm. long, lobes 0.2–0.5 x 0.1–0.2 mm.; style (0.5)2–5(6.5) mm. long, stigmas (4.8)6–14 mm. long (much shorter in odd hermaphrodite); ovary 0.7–1 x 0.6–0.8 mm., with 4 indistinct calyx lobes or calyx lobes ± lacking. Fruit reddish-brown; mericarps (1.5)1.8–2.2(2.4) x 0.8–1 mm., ± oblong to obovate, glabrous, with 2 indistinct, ± triangular calyx lobes 0.1–0.2 mm. long or calyx lobes ± lacking.
