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.

In contrast, a simple fruit develops from one ovary.

Not all flowers with multiple ovaries form aggregate fruit; the ovaries of some flowers do not become tightly joined together to make a larger fruit. Aggregate fruits may also be accessory fruits, in which parts of the flower other than the ovary become fleshy and form part of the fruit.

Aggregate fruits include:
 * Raspberry


 * Dewberry and Blackberry, also accessory fruit, with a fleshy receptacle


 * Strawberry, also an accessory fruit, with a fleshy receptacle
