The cowpea (Vigna unguiculata) is an annual herbaceous legume from the genus Vigna. It can be erect, semierect (trailing), or climbing. A high level of morphological diversity is found within the species with large variations in the size, shape, and structure of the plant. Four subspecies are recognised, three of which are cultivated. Its tolerance for sandy soil and low rainfall have made it an important crop in the semiarid regions across Africa and Asia. It was domesticated in Africa and is one of the oldest crops to be farmed. A second domestication event probably occurred in Asia, before
