A silique or siliqua (plural siliques or siliquae) is a fruit (seed capsule) of 2 fused carpels with the length being more than three times the width. The outer walls of the ovary (the valves) usually separate when ripe, leaving a persistent partition (the replum). This classification includes many members of the Brassicaceae family, but some species have a shorter fruit of similar structure, in which case the fruit is called silicle. Some species that are closely related to plants with true siliques have fruits with a similar structure that do not open when ripe; these are usually called indehiscent siliques (compare dehiscence).
