Etymology: "Legumen" is the Latin original of "legume," and English took it up as a technical term for the pod-bearing plants themselves. The Latin "legumen" came from "legere," meaning "to gather" or "to pick," because such pods were harvested by hand. Over time the word narrowed from a general sense of "pulse" or edible seed to the botanical family and its fruit. Its English relative, "legume," arrived through French and carries the same meaning, so the two are doublets: one entered by the scholarly route, the other by the everyday one. "Legumen" keeps the Latin form and feel, which is why it reads as a deliberate, slightly formal choice in English.
