A pome is an
accessory fruit composed of one or more
carpels surrounded by accessory tissue. The accessory tissue is interpreted by some specialists as an extension of the
receptacle and is then referred to as 'fruit cortex', and by others as a fused
hypanthium (floral cup). Although the
epicarp,
mesocarp, and
endocarp of some other fruit types look very much like the skin, flesh, and core respectively of a pome, they are parts of the carpel (see above diagram). The
epicarp and
mesocarp of a pome may be fleshy and difficult to distinguish from one another and from the hypanthial tissue. The endocarp forms a leathery or stony case around the
seed, and corresponds to what is commonly called the core. A pome-type fruit with a stony rather than a leathery
endocarp may be called a
polypyrenous drupe. The shriveled remains of the
sepals,
style and
stamens can sometimes be seen at the end of a pome opposite the stem, and the
ovary is therefore often described as
inferior in these flowers. ==Examples==
