Pericarp layers
In fleshy fruits, the pericarp is typically made up of three distinct layers: the outer epicarp, the middle mesocarp and the inner endocarp. These layers vary in thickness and texture, and may blend into each other. In a hesperidium like lemon, the epicarp and mesocarp make up the peel; in many berries like melons or cucumbers (pepo), the mesocarp and endocarp make up the flesh.
