Answer :Although sometimes called seedless tangerines, the sweet winter treats known as clementines are actually a variety of mandarin orange. Traditionally, clementines are said to be an accidental hybrid discovered by Father Clment Rodier in his garden in Algeria; they were introduced into California commercial agriculture in 1914. Although a clementine weighs only about half as much as a navel orange, ounce for ounce they are nutritionally similar: about the same amount of calories and potassium, while a navel orange contains slightly more fiber, vitamin C, calcium and folate per ounce. At only about 35 calories per fruit, clementines make an ideal snack.
