...Some species, such as the Tessen and the Acanthus gracilis, have retained their style and grown together with the ovary, making them useful for dispersal. In this way, a fruit whose structure involves parts other than the ovary is called a false fruit, and a fruit consisting only of the ovary is sometimes called a true fruit. However, the distinction between the two is not always clear. For example, in the case of persimmons, the calyx grows significantly, making it a false fruit, while in mandarin oranges, the calyx hardly grows at all, so calling it a true fruit is too artificial. *Some of the terminology that mentions "true fruit" is listed below.
