pome

The word pome entered English in the late 14th century, and referred to an apple or an apple-shaped object. It derived from the Old French word for "apple": {{lang|fro|pome}} (12th century; modern French is {{lang|fr|pomme}}), which in turn derived from the Late Latin or Vulgar Latin word {{lang|la|poma}} "apple", originally the plural of Latin {{wikt-lang|la|pomum}} "fruit", later "apple".{{cite web|last1=Harper|first1=Douglas|title=Online Etymological Dictionary: entry: pome|url=http://www.etymonline.com|website=Online Etymological Dictionary|access-date=2 June 2016}}

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",Esau, K. 1977. Anatomy of seed plants. John Wiley and Sons, New York. and by others as a fused hypanthium (floral cup). It is the most edible part of this fruit.{{Citation needed|date=February 2021}}

The carpels of a pome are fused within the "core".{{cite book |author1=Hickey, M. |author2=King, C. |year=2001|title=The Cambridge Illustrated Glossary of Botanical Terms |publisher=Cambridge University Press}} 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.{{Citation needed|date=February 2021}}

A pome-type fruit with a stony rather than a leathery endocarp may be called a polypyrenous drupe.{{cite journal|author1=Potter, D. |author2=Eriksson, T. |author3=Evans, R.C. |author4=Oh, S. |author5=Smedmark, J.E.E. |author6=Morgan, D.R. |author7=Kerr, M. |author8=Robertson, K.R. |author9=Arsenault, M. |author10=Dickinson, T.A. |author11=Campbell, C.S. |year=2007 |title=Phylogeny and classification of Rosaceae |journal=Plant Systematics and Evolution|volume=266 |issue=1–2 |pages=5–43 |url=https://rd.springer.com/journal/606/266/1/page/1| doi=10.1007/s00606-007-0539-9 |bibcode=2007PSyEv.266....5P |s2cid=16578516 |url-access=subscription }}

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.{{Citation needed|date=February 2021}}

The best-known example of a pome is the apple. Other examples of plants that produce fruit classified as a pome are Cotoneaster, Crataegus (hawthorn and mayhaw), medlar, pear, Pyracantha, quince, rowan, loquat, toyon, and whitebeam.{{Citation needed|date=February 2021}}

Some pomes may have a mealy texture (e.g., some apples); others (e.g., Amelanchier, Aronia) are berry-like with juicy flesh and a core that is not very noticeable.{{Citation needed|date=February 2021}}
