A clementine (Citrus × Clementina) is a tangor, a citrus fruit hybrid between a willow-leaf mandarin orange and a sweet orange. Named for its late 19th-century discoverer. The exterior is a deep orange color with a smooth, glossy appearance. Clementines can be separated into 7 to 14 segments. Similar to tangerines, they tend to be easy to peel. They are typically juicy and sweet, with less acid than oranges.
