In contrast, an
aggregate fruit such as a raspberry develops from multiple
ovaries of a single flower. In languages other than English, the meanings of "multiple" and "aggregate" fruit are reversed, so that multiple fruits merge several pistils within a single flower.[4]
In some cases, the infructescences are similar in appearance to simple fruits. One example is pineapple (Ananas), which is formed from the
fusion of the
berries with
receptacle tissues and
bracts.[5][6]
As shown in the photograph of the
noni, stages of flowering and fruit development in the
noni or Indian mulberry (Morinda citrifolia) can be observed on a single branch. First an inflorescence of white flowers called a head is produced. After
fertilization, each flower develops into a drupe, and as the drupes expand, they become connate (merge) into a multiple fleshy fruit called a syncarp. There are also many dry multiple fruits.[citation needed]
