drupe

The inside of cherry pits and other drupes like peaches and plums do indeed contain a chemical called amygdalin, which when ingested, is converted to cyanide.

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.

The ripe, oval drupes had fallen from buriti palms — also known as swamp palms — that live where the ground is waterlogged.

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.

So called for the singular pit or stone at the center — which houses a seed inside — stone fruit, also known as drupes, are generally in season late May through early October in the United States.
