Cowpeas can be divided into those grown for their seeds (beans or peas), which are usually dried, and those grown for their immature pods. The former, short plants with short pods, are those most often grown in Africa, India, and the USA. The latter, tall climbers with exceptionally long pods (the name ‘yard-long bean’ is not always an exaggeration), are favoured in SE Asia. But in some regions, such as the W. Indies, both sorts are cultivated. All are now assigned to V. unguiculata and the subspecies listed below, although some used to be classified as separate species.
