The cultivated species of the genus Vigna in Cuba have been studied on the basis of living material collected during recent missions and herbarium material. The highest variability was found in Vigna unguiculata subsp. unguiculata. Probably this race has been early introduced by the Spaniards to Cuba. Later on several species were introduced by east Asiatic immigrants. Introgression and adaptation are considered as the main causes for building up a pronounced infraspecific variation in Vigna unguiculata. A key for the cultivated species is provided.
