schizocarp

Dry fruit that develops from two or more carpels and splits, when mature, to form separate one-seeded units known as mericarps.

The mericarps may be dehiscent, splitting open to release the seed when ripe, as in Geranium, or indehiscent, remaining closed once mature, as in mallow Malva and plants of the Umbelliferae family, such as the carrot Daucus carota and parsnip Pastinaca sativa.
