Schizocarp

A split fruit is a subtype of the decay fruit. It disintegrates at maturity by splitting exclusively true septa into two or more partial fruits (mericarpia). Sometimes a stalk-like fruit holder (carpophor) remains between them. In contrast, the broken fruit breaks at maturity along false septa into several single-seeded subfruits, limbs.

Important plant families with split fruits in Central Europe are the maple family, most of the mallow family, the cranesbill family and the umbellifer family. In the latter, the split fruits are also called double achenes (cremocarp).

Special forms are the regma (coccarium) where the partial fruits open one by one (Castor, Geranium and Hura) and the carcerulus, where the individual partial fruits do not open and are detached as a whole, (marshmallow, Abutilon and mallow) the single-seeded partial fruits are called cocci (cocci). As well as the multiple winged nut (samara) which divides into the individual winged winged nuts.
