Staminate flowers: abaxial nectary 0.2-0.6 mm, adaxial nectary oblong, square, or ovate, 0.2-0.6 mm, nectaries distinct or connate and cup-shaped; stamens 3-7; filaments hairy basally; anthers 0.3-0.5 mm. Pistillate flowers: adaxial nectary square to oblong, 0.3-0.6 mm; stipe 0.4-2.4 mm; ovary pyriform to obturbinate, beak slightly bulged below or tapering to styles; ovules 8-18 per ovary; styles 0.2-0.3 mm; stigmas (sometimes slenderly cylindrical), 0.18-0.27-0.32 mm.
