Jícama (Spanish: hee-kah-mah, from Nahuatl xicamatl hee-kah-mahtl), also Mexican Potato an Mexican Turnip, is the name of a native Mexican vine, although the name most commonly refers to the plant's edible tuberous root. Jicama is one species in the genus Pachyrhizus that is commonly called yam bean, although the "yam bean" sometimes is another name for Jicama. The other, major species of yam beans are also indigenous within the Americas.
