A legume (pronounced /ˈlɛɡ(j)uːm/) in botanical writing is a plant in the family Fabaceae (or Leguminosae), or a fruit of these specific plants. A legume fruit is a simple dry fruit that 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 the term "pod" is also applied to a few other fruit types, such as vanilla and radish. Well-known legumes include alfalfa, clover, peas, beans, lentils, lupins, mesquite, carob, soy, and peanuts. Locust trees (Gleditsia or Robinia), wisteria, and the Kentucky coffeetree (Gymnocladus dioicus) are also legumes.
