Supplement

Angiosperm fruits may be classified based on the arrangement from which they derive: (1) simple fruit, (2) aggregate fruit, (3) multiple fruit, and (4) accessory fruit. Simple fruits are fruits that develop from a single or compound ovary with only one pistil (of a single flower).

Simple fruits may either be fleshy or dry fruits. Fleshy fruits are those fruits in which part or all of the pericarp is fleshy at maturity. Examples include berries (i.e. fruits in which the entire pericarp is soft and pulpy, e.g. grapes, tomatoes, bananas, pepo, hesperidium, blueberry, etc.) and drupes (i.e. fruits with pulpy, fibrous, or leathery outer layers while the endocarp hardens into a pit or stone enclosing one or more seeds, e.g. Peach, cherry, olive, coconut, walnut, etc.). Dry fruits may either be dehiscent (i.e. the hard or papery shells split open to release the mature seed, e.g. pods of the pea and bean), or indehiscent (i.e. fruits that do not split open, e.g. milkweed, achenes, etc). Types of dry simple fruits include achene (e.g. buttercup), capsule (e.g. Brazil nut), caryopsis (e.g. wheat), fibrous drupe (e.g. coconut), follicle (e.g. milkweed), legume (e.g. peanut), loment, nut (e.g. hazelnut), samara (e.g. elm), schizocarp (e.g. carrot seed), silique (e.g. radish seed), silicle (e.g. shepherd's purse), and utricle (e.g. beet).
