accessory fruit
An accessory fruit (sometimes called ''false fruit'', ''spurious fruit'', ''pseudofruit'', or ''pseudocarp'') is a fruit in which some of the flesh is derived not from the ovary but from some adjacent tissue exterior to the carpel.〔Esau, K. 1977. ''Anatomy of seed plants''. John Wiley and Sons, New York.〕 Examples of accessory tissue are the receptacle of the strawberry, pineapple, common fig, or mulberry, and the calyx of ''Gaultheria procumbens'' or ''Syzygium jambos''. Pomes, such as apples and pears, are also accessory fruits, with much of the fruit flesh derived from a hypanthium.〔Merriam Webster Collegiate Dictionary entries for (''syconium'' ), (''accessory fruit'' ), (''core'' ), and (''strawberry'' ), Merriam-Webster, Inc., 2006〕 Other example could be the ''anthocarps'' specific to the family Nyctaginaceae, where most of the fruit comes from the perianth (floral whorls).
Fruit with fleshy seeds, such as pomegranate or mamoncillo, are not considered to be accessory fruit.
The terms ''false fruit'', ''spurious fruit'', and ''pseudocarp'' are older terms for accessory fruit that have been criticized as "inapt",〔 and are not used by botanists today.
