Legume

A legume /ˈlɛɡʲuːm/ 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, soybeans, and peanuts. Locust trees (Gleditsia or Robinia), wisteria, and the Kentucky coffeetree (Gymnocladus dioicus) are also legumes. They are referred to in India as Kathod or pulses, and are often mistaken for nuts at first glance. Legumes are notable in that most of them have symbiotic nitrogen-fixing bacteria in structures called root nodules.
