A pome is a pitted fruit with a stony interior. The pit usually contains one seed chamber and one seed. This very specialized fruit type develops from the ovary, with most of the fleshy part formed from the receptacle tissue (the enlarged base of the perianth). Pomes are characteristic of one subfamily of the family Rosaceae (rose family). Examples of pomes are apple (Pyrus malus), pear (Pyrus communis), and quince (Cydonia oblonga).
