Avocado, Cherry, and Coconut technically are drupes (that is, fleshy, one-seeded fruits with the seed enclosed in a hard or stony shell. Walnuts and Hickories also are drupes.
Blackberry, Raspberry, and Loganberry fruits consist of an aggregation of drupelets, originating from a single flower. Mulberry is a multiple fruit in which the sepals of individual flowers of the female spike become fleshy and cover the real fruits — which we call “seeds.”
Strawberry also is an aggregate fruit in which the real fruits (achenes) are imbedded in a pulpy receptacle — the part we think of as the fruit.
The Fig is a composite fruit. The flowers, and subsequently the fruits (seeds to you and me), are borne on the interior of a pear-shaped hollow.
The Chokeberry is one of the pome fruits similar in structure to Apple and Pear, the best known fruits of this nature.
