Citrus is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, lemons, grapefruits, pomelos, and limes. The genus Citrus is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion ; and to the Middle East and the Mediterranean via the incense trade route, and onwards to Europe and the Americas.
Citrus hystrix, called the kaffir lime or makrut lime, is a citrus fruit native to tropical Southeast Asia.
Citrus cavaleriei, the Ichang papeda, is a slow-growing species of papeda that has characteristic lemon-scented foliage and flowers.
A lime is a citrus fruit, which is typically round, green in color, 3–6 centimetres (1.2–2.4 in) in diameter, and contains acidic juice vesicles.
Meghalaya is a state in northeast India. Meghalaya was formed on 21 January 1972 by carving out two districts from the state of Assam: (a) the United Khasi Hills and Jaintia Hills and (b) the Garo Hills. The population of Meghalaya as of 2014 is estimated to be 3,211,474. Meghalaya covers an area of approximately 22,429 square kilometres, with a length-to-breadth ratio of about 3:1.
Yuzu is a citrus fruit and plant in the family Rutaceae of East Asian origin. Yuzu has been cultivated mainly in East Asia, though recently also in New Zealand, Australia, Spain, Italy, and France.
Sudachi is a small, round, green citrus fruit of Japanese origin that is a specialty of Tokushima Prefecture in Japan. It is a sour citrus, not eaten as fruit, but used as food flavoring in place of lemon or lime. Genetic analysis shows it to be the product of a cross between a yuzu and another citrus akin to the koji and tachibana orange.
Citrus bergamia, the bergamot orange, is a fragrant citrus fruit the size of an orange, with a yellow or green color similar to a lime, depending on ripeness.
The Key lime or acid lime is a citrus hybrid is native to tropical Southeast Asia. It has a spherical fruit, 25–50 mm (1–2 in) in diameter. The Key lime is usually picked while it is still green, but it becomes yellow when ripe.
Papeda or papaeda is the common name for a group of Citrus species and varieties native to tropical Asia that are hardy and slow-growing, and produce unpalatable fruit. Walter Tennyson Swingle segregated these species into a separate subgenus, Papeda, that included the Ichang lemon, yuzu, kaffir lime, kabosu, sudachi, and a number of wild and uncultivated species and hybrids. Recent genetic analysis shows the papedas to be distributed among distinct branches of the Citrus phylogenetic tree, and hence Swingle's proposed subgenus is polyphyletic and not a valid taxonomic grouping, but the term persists as a common name.
