Sweet Potato

Sweet Potato (Ipomaea Batatas) a convolvulaceous plant, is unknown in a wild state but is extensively cultivated throughout the tropics and in Southern Europe. We import small quantities from Spaim. Its tubers reach a far larger size than those of the potato (q.v.), from which they also differ in containing 3 per cent. of sugar. They weigh about four or five pounds each. An allied species, I. chrysorhiza, is the "kumarah" eaten by the Maoris.
