Lime is a term referring to a citrus fruit which is typically round, green, 3–6 cm in diameter, and containing sour pulp. There are several species of citrus trees whose fruits are called limes, including the Key lime, Persian lime, kaffir lime, and desert lime. Limes are a good source of vitamin C, and are often used to accent the flavours of foods and beverages. They are grown year-round and are usually smaller and less sour than lemons.
