In contrast, anaggregate fruit such as a raspberry develops from multipleovaries 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 thefusion of theberries withreceptacle tissues andbracts.[5][6]
In some plants, such as thisnoni, flowers are produced continuously and it is possible to see examples of flowering, fruit development and fruit ripening together on a single stem.
As shown in the photograph of thenoni, stages of flowering and fruit development in thenoni or Indian mulberry (Morinda citrifolia) can be observed on a single branch. First an inflorescence of white flowers called a head is produced. Afterfertilization, each flower develops into a drupe, and as the drupes expand, they becomeconnate (merge) into amultiple fleshy fruit called asyncarp. There are also many dry multiple fruits.[citation needed]
