Are peanuts legumes? 

From time to time my husband and I get into a conversation and up pops a question. When we can't agree on the answer or we don't have an answer, I usually tell him, "I'll research that and get back to you." So, this section is dedicated to the topics I told him I'd research and get back to him on.

*This section is not intended to give definitive answers to anything. This is just for fun and most, if not all of my research came from the internet. I have tried to provide a bibliography so you can check out my sources.*

Peanuts are legumes. "Peanuts, along with beans and peas, belong to the single plant family, Leguminosae. Legumes are edible seeds enclosed in pods. As a group, they provide the best source of concentrated protein in the plant kingdom. While their physical structure and nutritional benefits more closely resemble that of other legumes, their use in diets and cuisines more closely resembles that of nuts. (1.)"

"A legume is a plant in the family Fabaceae (or Leguminosae), or a fruit of these plants. A legume 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 pod is also applied to a few other fruit types, such as vanilla. Well-known legumes include alfalfa, clover, peas, beans, lentils, lupins, and peanuts. 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. (2.)"
