Stamens with linear anthers and round-topped slightly extended connectives concealing anther cells. Pollen grains solitary. Carpels 10–15 with 2–8 ovules; stigma inconspicuous on a terete style. Apocarps mostly subglobular or ellipsoidal, fleshy, indehiscent. Seeds 1-several, broadly lenticular-discoid, pitted or smooth, brown.
