Types of Fruits

Indehiscent Fruits Dry fruits which do not split along definite lines to release seeds at maturity.

Examples: Achene Samara Caryopsis Nut

Achene Seed coat not fused with ovary wall.

Achene: Sunflower Seed

Samara Ovary wall forms a winglike structure. Dry; frequently used for seed dispersal by wind.

Samara: maple

Seed coat fused with ovary wall. Caryopsis (grain) Seed coat fused with ovary wall.

Caryopsis(grain): corn

Nut Ovary wall is tough and woody.

Nut: acorn

Fruits which open at maturity to shed their seeds. Dehiscent fruits Fruits which open at maturity to shed their seeds.

Examples: Follicle Legume Capsule

Fruit splits open along ONE seam. Follicle Fruit splits open along ONE seam.

Follicle: milkweed

Legume Fruit splits open along TWO seams.

Legume: bean

Capsule Fruit opens by various means, usually along more than two seams.

Capsule: lily

Fruit is generally moist and often edible. Fleshy Fruits Fruit is generally moist and often edible.

Examples: Drupe Berry False Berry Hesperidium Pome

Drupe Fruit is fleshy all the way out to the covering. Woody interior covering. The seed is covered by a very hard cover. Sometimes these are called stone fruits.

Drupe: plum, peach, almond, cherry

Berry Fruit is fleshy all the way out to the covering, which is usually thin. Interior seeds are NOT covered by a hard coat.

Berry: grape, tomato

False Berry Looks like a berry, but often has a harder outer coat. Seeds are clustered in the middle rather than throughout the fruit.

False Berry: cucumber, squash, pumpkin, cantaloupe

Hesperidium (not on your key) Outer soft rind which is white on the inside. Citrus Fruits belong here.

Hesperidium: orange, lemon, grapefruit

Pome Fruit is fleshy out to the covering. A few seeds are inside a core which is not eaten because it has a leathery interior coating.

Pome: pear, apple

Aggregate Fruits Fruit composed of mature ovaries from separate pistils of one flower Example: raspberry, strawberry

Multiple Fruits Fruit composed of mature ovaries from several flowers. Example: pineapple
