Aggregate fruit

A raspberry fruit is an aggregate fruit, an aggregate of drupelets

The fruit of an Aquilegia flower is an aggregate of follicles, but is not "an 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
