Definition
A siliqua is a type of dry fruit that develops from a flower with a superior ovary. It's longer than it is wide, typically at least three times as long. When ripe, it splits open along two seams to release its seeds. Think of it like a specialized pod, similar to a pea pod but with unique splitting characteristics. It's common in the mustard family (Brassicaceae). Imagine a tiny, elongated canoe filled with seeds, ready to set sail when the time is right.
