Species Citrus maxima - Pomelo Citrus medica - Citron Citrus reticulata - Mandarin & Tangerine Major hybrids Citrus x aurantifolia - Lime Citrus x aurantium - Bitter orange Citrus x bergamia - Bergamot Citrus x hystrix - Kaffir lime Citrus x ichangensis - Ichang lemon Citrus x limon - LemonLemons are the citrus fruit from the tree Citrus limon''. They are cultivated primarily for their juice, though the pulp and rind are also used, primarily in cooking. Lemon juice is about 5% citric acid, which gives lemons a sour taste. The lemon was unkn Citrus x limonia - RangpurRangpurs also known as lemanderins are a hybrid between the mandarin orange and the lemon. It is a citrus fruit of the species citrus limonia with a very acidic taste and an orange peel. Citrus x paradisi - GrapefruitGrapefruit Citrus X paradisi is a sub-tropical tree of the family Rutaceae and its citrus fruit. The evergreen tree is usually found at around 5-6 m tall, although it can reach 13-15 m. The leaves are dark green, long (up to 15 cm) and thin. It produces 5 Citrus x sinensis - Sweet orangeOranges are the fruits of an orange tree, one of the most common citrus fruits. Oranges are widely grown in warmer climates and are distributed worldwide. The name "orange" refers both to the fruit and its color — the color is named for the fruit.

Citrus is a common term and genusSee genus (mathematics) for the use of the term in mathematics. See genus (music) for the use of the term in music. In biology, a genus (plural genera is a grouping in the classification of living organisms having one or more related and morphologically s of flowering plant in the Family Rutaceae, originating in tropical and subtropical AsiaThe continent of Asia is defined by subtracting Europe and Africa from the great land mass of Africa-Eurasia. The boundaries are vague, especially between Asia and Europe: Asia and Africa meet somewhere near the Suez Canal. The boundary between Asia and E. The genus contains three speciesThis article discusses biological species. Also see combinatorial species for the mathematical meaning of the term. Species is also a movie by Roger Donaldson. In English "species" is both singular and plural. The word " specie" is unrelated and is used t, and numerous natural and cultivated origin hybrids, including commercially important fruit such as the orange, lemon, grapefruit, lime, and tangerine. The taxonomy of the genus is complex, but recent genetic evidence (see e.g. external link cited below) supports the presence of only three species, C. maxima, C. medica and C. reticulata, with all the other taxa previously accepted as species being of hybrid origin between these three. They are large evergreen shrubs or small trees, reaching 5-15 m tall.
Citrus fruits are notable for their fragrance, and most are juice-laden. They contain a high proportion of citric acid giving them their characteristic astringent odour and flavour. They are also good sources of vitamin C.
As citrus trees hybridize very readily (e.g., seeds grown from limes can produce fruit similar to grapefruit), all commercial citrus cultivation uses trees produced by grafting the desired fruiting cultivars onto rootstocks selected for disease resistance and hardiness.
