Dioscorea cayenensis
Also called Yellow Yam, Lagos Yam, Attoto Yam, Twelve Months Yam
Yellow guinea yam is a climbing tropical yam grown for its large, starchy underground tubers, widely cultivated across West Africa. It needs a warm, humid, frost-free climate, a long growing season, and a support to climb on.
Dioscorea cayenensis is a species of yam in the genus Dioscorea that is a widely consumed West African domesticated crop. Dioscorea rotundata is sometimes treated as a subspecies, and sometimes also as a separate species. Common names include Guinea yam, yellow yam, and yellow Guinea yam.
It may be a triploid hybrid between the cultivated D. rotundata and the wild D. burkilliana.
