is a plant of Peru. This species is cultivated in south America for its tuberous roots, which are about the size of hen's eggs, the skin being full of eyes like a potato. Herndon calls these tubers, when boiled or roasted, very agreeable to the taste. Carruthers says the plant is cultivated about Lima for its very acid leaf-stalks. it was introduced into England in 1829 but was found to be watery and insipid. There is a red and a yellow variety.
