Ziziphus zizyphusMHNT

Ziziphus jujuba (from Greek ζίζυφον, zízyphon<ref>ζίζυφον, Henry George Liddell, Robert Scott, A Greek-English Lexicon, on Perseus Digital Library</ref>), commonly called jujube<ref name=GRIN>Template:GRIN</ref> (Template:IPAc-en; sometimes jujuba), red date, Chinese date,<ref name=GRIN/> Korean date,Template:Citation needed or Indian dateTemplate:Citation needed is a species of Ziziphus in the buckthorn family (Rhamnaceae).


Plate from the book Flora de Filipinas

It is a small deciduous tree or shrub reaching a height of Template:Convert, usually with thorny branches. The leaves are shiny-green, ovate-acute, Template:Convert long and Template:Convert wide, with three conspicuous veins at the base, and a finely toothed margin. The flowers are small, Template:Convert wide, with five inconspicuous yellowish-green petals. The fruit is an edible oval drupe Template:Convert deep; when immature it is smooth-green, with the consistency and taste of an apple, maturing brown to purplish-black, and eventually wrinkled, looking like a small date. There is a single hard kernel, similar to an olive pit,<ref name="rushforth" /> containing two seeds.


Its precise natural distribution is uncertain due to extensive cultivation, but is thought to be in southern Asia, between Lebanon, northern India, and southern and central China, and possibly also southeastern Europe though more likely introduced there.<ref name=rushforth>Rushforth, K. (1999). Trees of Britain and Europe. Collins Template:ISBN.</ref>

This plant has been introduced in Madagascar and grows as an invasive species in the western part of the island. This plant is known as the "hinap" or "finab" in the eastern part of Bulgaria where it grows wild but is also a garden shrub, kept for its fruit. The fruit is picked in the autumn. The trees grow wild in the eastern Caribbean, and are reported to exist in Jamaica, The Bahamas, and Trinidad as well. In Antigua and Barbuda, the fruit is called "dumps" or "dums"; and in The Bahamas, "juju". It is also known as "pomme surette" on the French islands of the Caribbean. This fruit, more precisely known as "Indian jujube" elsewhere, is different from the "jujube" fruit that is cultivated in various parts of southern California.<ref>Template:Cite web</ref><ref>Template:Cite web</ref> Altun Ha an ancient Mayan city in Belize, located in the Belize District about 50 kilometres (31 mi) north of Belize City and the surrounding woods also boasts some jujube tree and shrub varieties where it is referred to as plums for lack of a better word among locals.


The species has a curious nomenclatural history, due to a combination of botanical naming regulations, and variations in spelling. It was first described scientifically by Carl Linnaeus as Rhamnus zizyphus, in Species Plantarum in 1753. Later, in 1768, Philip Miller concluded it was sufficiently distinct from Rhamnus to merit separation into a new genus, which he named Ziziphus jujube, using Linnaeus' species name for the genus but with a probably accidental single letter spelling difference, "i" for "y". For the species name he used a different name, as tautonyms (repetition of exactly the same name in the genus and species) are not permitted in botanical naming. However, because of Miller's slightly different spelling, the combination the earlier species name (from Linnaeus) with the new genus, Ziziphus zizyphus, is not a tautonym, and was therefore permitted as a botanical name. This combination was made by Hermann Karsten in 1882.<ref name=rushforth/><ref name=clarke>Clarke, D. L. (1988). W. J. Bean Trees and Shrubs Hardy in the British Isles, Supplement. John Murray Template:ISBN.</ref> In 2006, a proposal was made to suppress the name Ziziphus zizyphus in favor of Ziziphus jujuba,<ref>Template:Cite journal</ref> and this proposal was accepted in 2011.<ref>Template:Cite journal</ref> Ziziphus jujuba is thus the correct scientific name for this species.

Cultural and religious references

In Arabic-speaking regions the jujube and alternatively the species Z. lotus are closely related to the lote-trees (sing. "sidrah", pl. "sidr") which are mentioned in the Quran,<ref>Abdullah, Yusuf Ali (1946) The Holy Qur-an. Text, Translation and Commentary, Qatar National Printing Press. p.1139, n. 3814.</ref><ref>Template:Cite web</ref> while in Palestine it is rather the species Z. spina-christi that is called sidr.<ref>Template:Cite book</ref>


Varieties of jujube include Li, Lang, Sherwood, Silverhill, So, Shui Men and GA 866.<ref>Template:Cite web</ref>

Cultivation and uses

Ziziphus jujuba, written in Monbusho chant lyrics. It is now located in General Nogi's residence.

Jujube was domesticated in south Asia by 9000 BC.<ref name=gupta54>Gupta, Anil K. "Origin of agriculture and domestication of plants and animals linked to early Holocene climate amelioration", Current Science, Vol. 87, No. 1, 10 July 2004, 59. Indian Academy of Sciences.</ref> Over 400 cultivars have been selected.

The tree tolerates a wide range of temperatures and rainfall, though it requires hot summers and sufficient water for acceptable fruiting. Unlike most of the other species in the genus, it tolerates fairly cold winters, surviving temperatures down to about Template:Convert. This enables the jujube to grow in mountain or desert habitats, provided there is access to underground water throughout the summer. The jujube, Z. jujuba grows in cooler regions of Asia. Five or more other species of Ziziphus are widely distributed in milder climates to hot deserts of Asia and Africa.<ref>S. Chaudhary. "Rhamnaceae" in: S. Chaudhary (Ed).

In Madagascar, jujube trees grow extensively in the western half of the island, from the north all the way to the south. It is widely eaten by free-ranging zebus, and its seeds grow easily in zebu feces. It is an invasive species there, threatening mostly protected areas.

Culinary use

The freshly harvested, as well as the candied dried fruit, are often eaten as a snack, or with coffee. Smoked jujubes are consumed in Vietnam and are referred to as black jujubes.<ref>Template:Cite web</ref> Both China and Korea produce a sweetened tea syrup containing jujube fruit in glass jars, and canned jujube tea or jujube tea in the form of teabags. To a lesser extent, jujube fruit is made into juice and jujube vinegar (called or 红枣 in Chinese). They are used for making pickles (কুলের আচার) in west Bengal and Bangladesh. In China, a wine made from jujube fruit is called hong zao jiu (红枣酒).

Sometimes pieces of jujube fruit are preserved by storing them in a jar filled with baijiu (Chinese liquor), which allows them to be kept fresh for a long time, especially through the winter. Such jujubes are called jiu zao (酒枣; literally "alcohol jujube"). The fruit is also a significant ingredient in a wide variety of Chinese delicacies.Template:Which

In Vietnam and Taiwan, fully mature, nearly ripe fruit is harvested and sold on the local markets and also exported to Southeast Asian countries.<ref name="LIM"/> The dried fruit is used in desserts in China and Vietnam, such as ching bo leung, a cold beverage that includes the dried jujube, longan, fresh seaweed, barley, and lotus seeds.<ref name="LIM">Template:Cite book</ref>

In Korea, jujubes are called daechu (대추) and are used in daechucha teas and samgyetang.

In Croatia, especially Dalmatia, jujubes are used in marmalades, juices, and rakija (fruit brandy).

On his visit to Medina, the 19th-century English explorer, Sir Richard Burton, observed that the local variety of jujube fruit was widely eaten. He describes its taste as "like a bad plum, an unrepentant cherry and an insipid apple." He gives the local names for three varieties as "Hindi (Indian), Baladi (native), Tamri (date-like)."<ref>Burton, Sir Richard Francis (1855) A Personal Narrative of a Pilgrimage to Al-Madinah and Meccah pp.404,405</ref> In Palestine a hundred years ago, a close variety was common in the Jordan valley and around Jerusalem.<ref>Easton, M.G., M.A., D.D.

In Persian cuisine, the dried drupes are known as annab, while in neighboring Azerbaijan, it is commonly eaten as a snack, and is known as innab. Confusion in the common name apparently is widespread. The innab is Z. jujuba: the local name ber is not used for innab. Rather, ber is used for three other cultivated or wild species, e.g., Z. spina-christi, Z. mauritiana, and Z. nummularia in Pakistan and parts of India and is eaten both fresh and dried. The Arabic name sidr is used for Ziziphus species other than Z. jujuba.

Traditionally in India, the fruit is dried in the sun and the hard nuts are removed. Then, it is pounded with tamarind, red chillies, salt, and jaggery. In some parts of the Indian state of Tamil Nadu, fresh whole ripe fruit is crushed with the above ingredients and dried under the sun to make cakes called ilanthai vadai or regi vadiyalu (Telugu).<ref>Template:Cite web</ref> It is also commonly consumed as a snack.

In Northern and Northeastern India the fruit is eaten fresh with salt and chilli flakes and also preserved as candy, jam or pickle with oil and spices.

In Madagascar, jujube fruit is eaten fresh or dried. People also use it to make jam. A jujube honey is produced in the Atlas Mountains of Morocco.<ref name="LIM"/>

Italy has an alcoholic syrup called brodo di giuggiole.<ref>Template:Cite web</ref> In Senegal Jujube is called Sii dem and the fruit is used as snack. The fruit is turned into dried paste used by school kids.

The commercial jujube candy popular in movie theaters originally contained jujube juice but now uses other flavorings.
