The flowers are pale green and clustered in clusters on axillary pedicels. The flower is nearly round, outward-curved, cup-shaped, and nearly pentagonal. The male filaments are extremely short and located at the edge of the flower disk. The anthers are split and laterally lobed. Most of the ovary is hidden within the flower disk. The style is cylindrical and truncated at the tip. The berries are nearly spherical. The outer pericarp is woody when dry, with fine nodules or smooth. Most seeds have sharp edges.
