Fruit drupe attached to the receptacle. In some bramble fruits (such as blackberry) the receptacle is elongated and part of the ripe fruit, making the blackberry an "aggregate-accessory" fruit. The strawberry is also an aggregate-accessory fruit, only one in which the seeds are contained in achenes. In all these examples, the fruit develops from a single flower with numerous pistils. A multiple fruit is one formed from a cluster of flowers (called an "inflorescence"). Each flower produces a fruit, but these mature into a single mass. Examples are the pineapple, fig, mulberry, osage-orange, and breadfruit. In the photograph on the right,
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. In contrast, a "simple fruit" develops from one ovary. In languages other than English, the meanings of aggregate and multiple fruit are reversed, so that aggregate fruits merge several flowers. The differences in meaning are due to a reversal in the terminology by John Lindley, which has been followed by most English-language authors. Not all flowers with multiple ovaries form aggregate fruit; the ovaries of some flowers do not become tightly joined together to
