Pomes, such as apples and pears, are also accessory fruits, with much of the fruit flesh derived from a hypanthium. Other example could be the "anthocarps" specific to the family Nyctaginaceae, where most of the fruit comes from
Aggregate fruit Aggregate fruit An aggregate fruit or etaerio () is a fruit that develops from the merger of several ovaries that were separate in a single flower.
