Dioscorea cayennensis subsp. rotundata, commonly known as the white yam, West African yam,[1] Guinea yam, or white ñame, is a subspecies[2] of yam native to Africa. It is one of the most important cultivated yams.[3] Kokoro is one of its most important cultivars.
It is sometimes treated as separate species from Dioscorea cayennensis.[1]
Its wild progenitor is Dioscorea praehensilis.[1]
Distribution
D. c. subsp. rotundata is grown in West Africa, including countries such as Ivory Coast, Ghana and Nigeria.[4]
