Flowers unisexual, 4-merous. Pedicels 6-10 mm. Petals present. Female flowers few- to 20-fascicled in leaf axils of long shoots or on short shoots; sepals ovate-lanceolate, 3-4 × as long as calyx tube, with rudimentary stamens; style 2-fid or cleft to half. Drupe black, globose or obovoid-globose, 5-6 mm in diam., with 2 stones, with persistent calyx tube at base; fruiting pedicel 6-10 mm.
