An accessory fruit is a fruit in which some of the flesh is derived not from the floral ovary but from some adjacent tissue exterior to the carpel.[1]
Terminology
Alternative terms for accessory fruit are false fruit, spurious fruit, pseudofruit, or pseudocarp. These are older terms for accessory fruit that have been criticized as "inapt",[1] and are not used by some botanists today.
Examples
The following are examples of accessory fruits listed by the plant organ from which the accessory tissue is derived:[2]
- Hypanthium-derived: pomes (e.g. apple and pear)
- Perianth-derived: anthocarps of the Nyctaginaceae
- Receptacle-derived: fig, mulberry, pineapple, and strawberry
- Calyx-derived: Gaultheria procumbens and Syzygium jambos
Fruit with fleshy seeds, such as pomegranate or mamoncillo, are not considered to be accessory fruits.
