Legume

n. plant belonging to the legume family; pod or seed container produced by a legume plant; vegetable belonging to the legume family

A legume is a simple dry fruit which develops from a simple carpel and usually dehisces (opens along a seam) on two sides. A common name for this type of fruit is a "pod", although pod is also applied to a few other fruit types. A peanut is not a nut in the botanical sense; a peanut is an indehiscent legume, that is, one whose pod does not split open on its own.
