Inflorescences: staminate 0.8-2.6 cm; pistillate 3-6 mm at anthesis, enlarging to 2 cm in fruit. Flowers unisexual, staminate and pistillate on different plants. Staminate flowers: bract of flower longer than stamens, gland-dotted at base, distal margins transparent, occasionally ciliate; stamens 3-5. Pistillate flowers: bracteoles 2, accrescent and adnate to base of fruit wall, laterally compressed, densely pilose with some hairs persistent, especially toward apex, glandular; ovary glabrous. Fruits ovoid, flattened, 1.5-2.5 mm; fruit wall smooth, without waxy deposits, enclosed by spongy bracteoles.
