Flowers unisexual, 4-merous, usually 3-6-fascicled on short shoots. Pedicels 2-3 mm, pilose. Petals lanceolate, subequaling stamens. Styles in female flowers 2-fid or cleft to half. Drupe black at maturity, subglobose, 3-4 mm in diam., with 2 stones, with persistent calyx tube at base; fruiting pedicel 2-3 mm, pilose.
