basically clementines are seedless
i have attached more information and included satsumas and mandarins too
hope this answers it for you
tangerine
The Tangerine (Citrus reticulata) is an orange or red colored citrus fruit, a type of mandarin orange.
They are smaller than most oranges, and the skin of some varieties peels off more easily. The flavor is often more sour and more sweet than that of an orange.
Good quality tangerines will be firm to slightly hard, heavy for their size and pebbly-skinned with no deep grooves, also orange in color. Peak tangerine season is short, lasting from November to January in the Northern Hemisphere.
The Honey tangerine, which was originally called a murcott, is very sweet as its name suggests. Other popular kinds include the Sunburst and Fairchild tangerines.
One of the oldest varieties is the Dancy tangerine, once the most popular type, but no longer widely grown [1]. The Dancy was known as the zipper-skin tangerine and as the kid-glove orange for its loose, pliable peel. Its peak season is December, so children often received one in their Christmas stockings.
Tangerine flavor is used in bottled juice soft drinks, and the fresh fruit can be used in salads, desserts and main dishes. It is, however, most commonly eaten out of hand. Tangerines are a good source of vitamin C, folate and beta-carotene. They also contain some potassium, magnesium and vitamins B1, B2 & B3.
The number of seeds in each segment (carpel) varies greatly (up to 59).
Historically the name tangerine comes from Tangier, Morocco, the port from which the first tangerines were shipped to Europe. The adjective tangerine, from Tangier or Tanger, was already an English word (first recorded in 1710).
A popular alternative to tangerines are Clementines, which are also a variant of the mandarin orange.
clementine
A clementine is the fruit of a variety of mandarin (Citrus reticulata), named in 1902. The traditional story is that it was "originally an accidental hybrid said to have been discovered by Father Clément Rodier in the garden of his orphanage in Misserghin, Algeria."[1] However, there are claims it originated in China much earlier. James Saunt writes: "Some authorities believe it is virtually identical to the variety known as the Canton mandarin widely grown in Gwangxi and Guangdong Provinces in China." In Arabic, it is called "Kalamintina".
The clementine is not always distinguished from other varieties of mandarin: in German, it is generally referred to as "Mandarine" and in Japanese, mikan. However, it should not be confused with similar fruit such as the satsuma, another popular variety. The clementine is occasionally referred to as Algerian tangerine.
A clementine is an oblate, medium-sized fruit. The exterior is a deep orange colour with a smooth, glossy appearance. Clementines separate easily into eight to twelve juicy segments.
This variety was introduced into California commercial agriculture in 1914, though it was grown at the Citrus Research Center at the University of California, Riverside as early as 1909. Clementines, usually grown in Morocco and Spain, have been available in Europe for many years. A market for them in the United States was created recently, when the harsh 1997 winter in Florida devastated domestic orange production, increasing prices and decreasing availability. California clementines are available from mid-November through January; this availability has them referred to in some areas as "Christmas Oranges".
Clementines lose their desirable seedless characteristic when bees cross-pollinate them with other fruit. In early 2006 large growers such as Paramount Citrus in California threatened to sue local beekeepers for their bees' trespass into clementine crop land
satsuma
Citrus unshiu Marc. is a seedless and easy-peeling citrus mutant of Japanese origin, known as unshiu mikan (Japanese: 温州蜜柑, unshū mikan, lit. unshiu sweet citrus) in Japan.[citation needed]
It is commonly called mikan in Japan, satsuma in the UK, naartjie in Africa and mandarin or tangerine in Canada. In the United States, satsumas are most frequently marketed as tangerines. It is less commonly called satsuma tangerine, satsuma orange, or satsuma mandarin.[citation needed]
Its fruit is sweet and usually seedless, about the size of other mandarin oranges (Citrus reticulata), smaller than an orange.[citation needed] One of the distinguishing features of the satsuma is the distinctive thin, leathery skin dotted with large and prominent oil glands, which is lightly attached around the fruit; enabling it to peeled very easily in comparison to other citrus fruits. The satsuma also has particularly delicate flesh, which cannot withstand the effects of careless handling. The uniquely loose skin of the satsuma, however, means that any such bruising and damage to the fruit may not be immediately apparent upon the typical cursory visual inspection associated with assessing the quality of other fruits. In this regard, the satsuma is often categorised by citrus growers as a hit-and-miss citrus fruit; the loose skin particular to the fruit precluding the definitive measurement of its quality by sight and feel alone.
While the name "unshiu" (温州) is supposed to derive from Wenzhou, a city in the Zhejiang Province of China known for its citrus production, the tree is believed to have originated from a mutation in Japan, recorded as early as 1429 [1].
In the UK and the U.S., mikan are commonly available in the winter months (December through January). They are widely available in the U.S. and commonly eaten regardless of region.
Clementines are not the same variety as the unshiu or satsuma mandarin. Because of their popularity, clementines are the variety of mandarin most often seen in some markets. In Canada, they are a popular snack at any time of the year,[citation needed] and fruit grown in Morocco are commonly sold in supermarkets.
mandarin
The Mandarin orange or mandarin is a small citrus tree (Citrus reticulata) with fruit resembling the orange. The fruit is oblate, rather than spherical, and roughly resembles a pumpkin in shape. Mandarin oranges are usually eaten plain or in fruit salads. Specifically reddish orange mandarin cultivars can be marketed as a tangerine, but this is not a botanical classification.
The tree is more tolerant to drought than the fruit. The mandarin is tender and gets damaged easily by the cold. It can be grown in tropical and subtropical areas.
Varieties and characteristics
The mandarin has many names, some of which actually refer to crosses between the mandarin and another citrus fruit. Most canned mandarins are of the satsuma variety, of which there are over 200 cultivars. Satsumas are known as mikan in Japan. One of the more well-known satsuma cultivars is the "Owari", which ripens during the late fall season in the Northern Hemisphere. Clementines, however, have displaced satsumas in many markets and are becoming the most important commercial mandarin variety.
The tangor, which is also called the temple orange, is a cross between the mandarin and the common orange. Its thin rind is easy to peel; and its pale orange pulp is spicy, full-flavored,tart and sour.
The rangpur is a cross between the mandarin and the lemon.
Biological characteristics
Citrus fruit varieties are usually self-fertile (needing the bee only to move pollen within the same flower) or parthenocarpic (not needing pollination and therefore seedless) (such as satsumas).
Blossoms from the Dancy cultivar are, as an example, an exception. They are self sterile, therefore must have a pollenizer variety to supply pollen, and a high bee population to make a good crop.
Further, some varieties, notably clementines, are usually seed free, but will develop seeds if cross pollinated with seeded citrus. Thus, great efforts are taken to isolate clementine orchards from any seeded citrus varieties.
