Inflorescences between the leaves, of the Knema-type: sessile or to 1.5 mm pedunculate, slender, simple or forked scar-covered brachyblasts to 6 mm long, glabrescent; in male: ending in 1 or 2 loose clusters each with 1-3 flowers, buds of various sizes; bracts 0.5 mm, short-pubescent, caducous; female inflorescences consisting of merely one axillary flower; flowers with hairs 0.1 mm or less. Male flowers: pedicel 3-4.5 by 0.4 mm, bracteole 1 mm, persistent, 1-2 mm below apex; buds (submature) ovoid-oblong, 3.5(-4) by 1 mm, apex narrowly rounded, cleft c. 1/4, lobes membranous, 1 mm long, 0.2 mm thick. Androecium 3.5 mm; androphore 1.7 by 0.3 mm, with hairs 0.1 mm all over; synandrium 1.8 by 0.4 mm, thecae 6, sterile apex 0.1 mm. Female flowers: pedicel slender, 5 mm long, bracteole scar about halfway; buds ovoid-oblong, 3.5 by 1.5(-2) mm, lobes 0.7 mm; ovary 2.5 by 1(—1.5) mm, minutely pubescent. Fruits solitary, ± ellipsoid-oblong, 3-3.5 by 1-1.3 cm, apex subacute with minute apiculum (stigma remnant), the basal part contracted into a narrow pseudostalk, 10 mm long, hairs dull brown, 0.1 mm or less; pericarp 1 mm thick or less; seeds ellipsoid, 1.7-2 cm; fruiting pedicel slender, 8-12 by 0.5 mm, bracteole scar at or below the middle.
