jicama

The jícama (pronounced "hee-kuh-muh"; from Spanish, derived from Nahuatl xicamatl), also known as the Mexican Potato or Mexican Turnip, is the name of a vine native to Mexico and Central America, although the name is most commonly used to refer only to the edible tuberous root of the plant. The jicama is one species in a genus (Pachyrhizus) which is commonly referred to as yam beans, although the name "yam bean" is sometimes used as another name for the jicama specifically. The other major species of yam beans are indigenous to other parts of the Americas.
