Schizocarp

A schizocarp is a dry fruit that develops from multiple carpels. When mature it splits up into mericarps. Mericarps are often 1-seeded, but in some plants the mericarps have two or more seeds. The mericarp is either dehiscent (splits open to release the seed), or indehiscent (remaining closed).
