There are a few fruits formed from a group of flowers (inflorescence) rather than just one, but which form only one fruit. These are Sorosis, as in the Mulberry (Morus), Syngonium, as in the Fig (Ficus), and Coenocarpium, as in the Pineapple (Ananas).

Multiple fruits are derived from ovaries of several flowers. An example you would be familiar with would be a pineapple. An example of a native plant would be the fused double berry of Lonicera.

An aggregate fruit, or etaerio, develops from a flower with numerous simple pistils.[14] An example is the raspberry, whose simple fruits are termed drupelets because each is like a small 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.[15] The strawberry is ... an aggregate-accessory fruit, only one in which the seeds are contained in achenes.[16] In all these examples, the fruit develops from a single flower with numerous pistils.
