The flowers are borne in groups of up to ten on a rachis 20–40 mm long, each flower on a winged pedicel 2–4 mm long. The flowers have five narrow egg-shaped sepals 10–11 mm long and 2–3 mm wide. The five petals are white, narrow oblong, 10–14 mm long and about 2 mm wide with thin lobes at the tip, and there are fifteen or sixteen stamens. The fruit is a more or less spherical drupe about 13–15 mm long and 12–14 mm wide.
