Potato - one of some 150 tuber-bearing species of the genus Solanum (family Solanaceae). The potato (common potato, white potato, or Irish potato), considered by most botanists a native of the Peruvian-Bolivian Andes, is one of the world’s main food crops, differing from others in that the edible part of the plant is a tuber (i.e., the swollen end of an underground stem).
