Follicle (fruit)

A follicle (also folliculus ) is an opening fruit or fruit scattering. It usually consists of a dry, mostly leathery pericarp ( pericarp ), which usually contains several seeds.

The follicle is formed from a single carpel in a superior ovaries. This carpel grows together with itself, usually with clearly visible seams. Along this concrescence sit the seeds; and along this concrescence, the fruit opens at maturity. Most contain the flower, from the developing follicles, several ovary, so that develop several fruits that stand together in a whorl. Are these individual fruits inseparably fused together so that they form a unit, it is called a Sammelbalgfrucht. A special form of Sammelbalgfrucht is the apple fruit in which the individual bladders are overgrown with tissue flowers soil. In this case, the bellows can hardly open and the seeds may be released after removal of the pulp.

Development History of the follicle is the closest legume. Follicles are the most primitive form of fruit; so are original taxa of angiosperms, in which one finds follicles.

Among the taxa that form follicles, include original taxa such as the families of the buttercup family ( Ranunculaceae ), peony plants ( Paeoniaceae ) Sternanisgewächse ( Schisandraceae ) Crossosomataceae, Limnocharitaceae, Petrosaviaceae, the subfamily of Spiraeoideae in the Rosaceae, genus Magnolia (Magnolia ).
