The adzuki bean (Vigna angularis; from the Japanese アズキ(小豆) (azuki?), sometimes transliterated as azuki or aduki, or English Red Mung Bean) is an annual vine widely grown throughout East Asia and the Himalayas for its small (approximately 5 mm) bean. The cultivars most familiar in Northeast Asia have a uniform red colour, however, white, black, gray, and variously mottled varieties also are known. Scientists presume Vigna angularis var. nipponensis is the progenitor.[citation needed]
