hesperidium

Clymenia fruits are a small hesperidium, very similar to a citrus fruit.

The fruit is an edible red hesperidium similar to a small Citrus fruit.

A fruit with a thick peel, such as a citrus fruit, is called a hesperidium.

A hesperidium (plural hesperidia) is a modified berry with a tough, leathery rind.

A hesperidium (pronounced hes' per id' ee uhm) is another modified berry.

In a hesperidium such as a citrus fruit, the mesocarp is also referred to as albedo or pith.

In many languages, oranges are, implicitly or explicitly, referred to as a type of apple, specifically a golden apple or a Chinese apple (confer hesperidium).

Two additional genera: Triphasia and Clymenia are likewise very closely related, and bear hesperidium fruits, but are not considered part of the Citrus genus.

The fruit of citrus, such as the orange, kumquat and lemon, is a berry with a thick rind and a very juicy interior that is given the special name hesperidium.

Pumpkins, cucumbers, melons, oranges and lemons are also berries that have slightly different structure and may be called by different names (pepo for pumpkins, cucumbers, and melons, or hesperidium for oranges and lemons).

The fruit of any citrus tree is considered a hesperidium (a kind of modified berry) because it has numerous seeds, is fleshy and soft, derives from a single ovary and is covered by a rind originated by a rugged thickening of the ovary wall.
