Multiple fruits of the mulberry family are composed of numerous, seed-bearing, ripened ovaries derived from numerous separate flowers. The multiple fruit of a mulberry (Morus) is composed of a cluster of drupelets superficially resembling a blackberry; however, unlike a blackberry, each drupelet arises from a separate minute flower. In the aggregate fruit of a blackberry, all the drupelets of the cluster come from a single flower. The fig (Ficus) is a very unique genus in the mulberry family with a special kind of multiple fruit called a syconium. The pollen-bearing male and seed-bearing female flowers line the inside of a fleshy, flask-shaped structure called a syconium. The tiny female flowers are pollinated by symbiotic female wasps who enter the syconium through a pore (ostiole) at one end.
