Pseudo-carps are fruiting bodies that resemble fruits, but are not true fruits. There are several synonyms for pseudo-carps, including false fruits, spurious fruits, and accessory fruits. False fruits refer to plant structures that appear to be fruits, but are not derived from the ovary. Spurious fruits are similar to false fruits, except that they are produced by other parts of the flower besides the ovary. Accessory fruits, on the other hand, are true fruits that include structures from other parts of the flower, such as the receptacle or calyx. Despite their differences, all of these terms describe structures that mimic fruits in appearance, but have a different biological origin.
