Accessory fruit
An
accessory fruit is a
fruit in which the fleshy part is derived not from the
ovary (or surrounding stem, if the ovary is inferior) but from some adjacent tissue. Examples are the
fig (the fleshy part is a hollow ball with the flowers inside), the
strawberry (the fleshy part is a peg with the carpels on it), and the
cashew apple (the fleshy part is the stem, but the ovary is superior).
