Inflorescences between the leaves, axillary or to 7 mm supra-axillary, ± paniculate, with slender peduncle, early glabrescent; in male 6-10 cm long, peduncle 3-5 cm, lower branches 1-2.5 cm, central axis 1-3 cm, with 1-3 side branches to.1 cm long, all branches ending in scar-covered brachyblasts to 5 mm, each with a subumbel of 4-10 flowers, buds of various sizes; bracts small, 1-2 mm, late caducous; in female: peduncle 2.5-3 cm, shorter and less branched than the male, subumbels 2-4-flowered; flowers with sparse, dark-brown, appressed hairs, partly glabrescent Male flowers: pedicel 10-12 by 0.4-0.6 mm, bracteole 0.5-1 mm, half-circular, persistent, subapical; buds membranous, elongate, almost tubiform, narrowed to both ends, especially towards the apex, 12-13 by 2.5(-3) mm, cleft c. 1/10, lobes 1-1.5 mm, erect, 0.2 mm thick. Androecium slender, 8-9 mm long; androphore 3-3.5 by 0.5 mm, hairsless than 0.1 mm; synandrium 4.5-5.5 by 0.6-0.8 mm, thecae 10-12, sterile apex 0.2-0.3 mm, with 5 or 6 lobules corresponding with the anthers. Female flowers: pedicel rather stout, 18-20 mm, bracteole 2-5 mm below the apex; buds ovoid-oblong, narrowed towards the apex, 9 by 3-3.5 mm, lobes 1 mm long; ovary ovoid-oblong, 6-7 by 2-3 mm (including the 1 mm long deeply 2-lobed stigma), hairs dense, pale brown, less than 0.1 mm. Fruits single, oblong, 3-3.5 by 1-1.3 cm, top acute, base ± narrowed into 3-5 mm long pseudostalk, hairs scale-like, 0.1 mm; pericarp 1 mm thick; seeds 2-2.5 cm.
