Inflorescence axillary, paniculate, unisexual; male ones 6-15 cm long, usually twice branched, the branches few, peduncle up to 2 cm long supporting subglobose dense clusters 5-10 mm in diameter spaced along the branches, each cluster with 80-100 subsessile very fragrant flowers; female ones smaller, little branched, up to 4 cm long, the flowers solitary or few together; male flowers with pedicel 0.3 mm long, perianth 3-4-lobed, 3 mm long, androecium elongate, narrowly obconical or ellipsoid-oblong, 1 mm long, thecae 6-10, largely sessile, erect, free apices 0.2 mm long, column narrow, hollow to halfway; female flowers on short pedicel, perianth 2-3-lobed, 3 mm long, ovary broadly ellipsoid, 2 mm long, stigma minutely 2-4-lobed.
