drupe

First, there are those cashews, which are not nuts at all but technically fruit; they’re the drupe seeds that extend under the apple of the cashew tree.

Though sometimes referred to as a berry, the fruit of Piper nigrum is a drupe, as are stone fruits, meaning that it consists of a seed in the center surrounded by a layer of flesh.

While their name implies they are berries, mulberries, blackberries, and raspberries are actually aggregate fruits in the drupe or stone fruit family.

In botany, this is called the suture, and it gives drupe fruits, a category that includes peaches, plums and olives, a seam that can split to release its seed-bearing pit.
