GrapefruitGrapefruit & pomelo

The grapefruit (Citrus × paradisi) is a subtropical citrus tree known for its sour to semi-sweet fruit. Grapefruit is a hybrid originating in Barbados as an accidental cross between two introduced species, sweet orange (C. sinesis) and pomelo or shaddock (C. maxima), both of which were introduced from Asia in the seventeenth century. When found, it was named the “forbidden fruit”; and it has also been misidentified with the pomelo.

The evergreen grapefruit trees usually grow to around 5–6 meters (16–20 ft) tall, although they can reach 13–15 m (43–49 ft). The leaves are glossy dark green, long (up to 15 centimeters (5.9 in)) and thin. It produces 5 cm (2 in) white four-petaled flowers. The fruit is yellow-orange skinned and generally an oblate spheroid in shape; it ranges in diameter from 10–15 cm (3.9–5.9 in). (Source: Wikipedia)

lemonLemons and Limes

The lemon (Citrus × limon) is a species of small evergreen tree native to Asia.The tree’s ellipsoidal yellow fruit is used for culinary and non-culinary purposes throughout the world, primarily for its juice, which has both culinary and cleaning uses. (Source: Wikipedia)


The orange (specifically, the sweet orange) is the fruit of the citrus species Citrus × sinensis in the family Rutaceae.The fruit of the Citrus × sinensis is considered a sweet orange, whereas the fruit of the Citrus × aurantium is considered a bitter orange. The sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of sweet orange arise through mutations.

The orange is a hybrid, between pomelo (Citrus maxima) and mandarin (Citrus reticulata). It has genes that are ~25% pomelo and ~75% mandarin; however, it is not a simple backcrossed BC1 hybrid, but hybridized over multiple generations. The chloroplast genes, and therefore the maternal line, seem to be pomelo. The sweet orange has had its full genome sequenced. Earlier estimates of the percentage of pomelo genes varying from ~50% to 6% have been reported. (Source: Wikipedia)

ClementineTangerines, mandarins, clementines

A clementine (Citrus ×clementina) is a hybrid between a Mediterranean Citrus ×deliciosa and a sweet orange,so named in 1902. The exterior is a deep orange colour with a smooth, glossy appearance. Clementines can be separated into 7 to 14 segments. Similarly to tangerines, they tend to be easy to peel.

This variety was introduced into California commercial agriculture in 1914, though it was grown at the Citrus Research Center (now part of the University of California, Riverside) as early as 1909. Clementines lose their desirable seedless characteristic when they are cross-pollinated with other fruit. To prevent this, in 2006 growers such as Paramount Citrus in California threatened to sue local beekeepers to keep bees away from their crops. (Source: Wikipedia)
