The Lychee ("Litchi chinensis"), also spelled Litchi (the U.S.
FDAspelling) or Laichi and Lichu, Chinese: 荔枝, Hanyu Pinyin: Lìzhī, is the sole member of the genus "Litchi" in the soapberry family Sapindaceae. It is a tropical fruit treenative to southern China. It is also commonly found in Madagascar, India, Bangladesh, Pakistan, southern Taiwan, northern Vietnam, Indonesia, Thailand, the Philippines, and Southern Africa.
It is a medium-sized
evergreentree, reaching 15–20 m tall, with alternate pinnateleaves, each leaf 15–25 cm long, with 2-8 lateral leaflets 5–10 cm long; the terminal leaflet is absent. The newly emerging young leaves are a bright coppery red at first, before turning green as they expand to full size. The flowers are small, greenish-white or yellowish-white, produced in panicles up to 30 cm long.
The fruit is a
drupe, 3–4 cm long and 3 cm in diameter. The outside is covered by a pink-red, roughly-textured rindthat is inedible but easily removed. The inside consists of a layer of sweet, translucent white flesh, rich in vitamin C, with a texture somewhat similar to that of a grape. The edible flesh consists of a highly developed arilenveloping the seed. The center contains a single glossy brown nut-like seed, 2 cm long and 1–1.5 cm in diameter. The seed, similar to a buckeye seed, is not poisonous but should not be eaten. The fruit matures from July to October, about 100 days after flowering.There are two subspecies:
*"Litchi chinensis" subsp. "chinensis". China, Indochina (
Vietnam, Laosand Cambodia). Leaves with 4 to 8 (rarely 2) leaflets.
*"Litchi chinensis" subsp. "philippinensis" (Radlk.) Leenh. Philippines, Indonesia. Leaves with 2-4 (rarely 6) leaflets.
A major early Chinese historical reference to lychees was made in the
Tang Dynasty, when it was the favourite fruit of Emperor Li Longji (Xuanzong)'s favoured concubine Yang Yuhuan (Yang Guifei). The emperor had the fruit, which was only grown in southern China, delivered by the imperial messenger service's fast horses, whose riders would take shifts day and night in a Pony Express-like manner, to the capital. (Most historians believe the fruits were delivered from modern Guangdong, but some believe they came from modern Sichuan.)
In the Chinese classical work, "Shanglin Fu" (上林賦), it is related that the alternate name, 離枝 (pinyin: lízhī), meaning leaving its branches, is so-called because once the fruit is picked it deteriorates quickly.
The lychee was first described in the West by
Pierre Sonnerat(1748–1814) on a return from his travel to Chinaand Southeast Asia.
It was then introduced to the
RéunionIsland in 1764 by Joseph-François Charpentier de Cossigny de Palma. It was later introduced to Madagascarwhich has become a major producer.
Cultivation and uses
Lychees are extensively grown in the native region of
China, and also elsewhere in South-East Asia, especially in north of Thailand, Laos, Cambodia, Vietnam, Bangladesh, India, southern Japan, Taiwan, and more recently in California, Hawaii, Florida[http://edis.ifas.ufl.edu/MG051] in the United States, the wetter areas of eastern Australiaand sub-tropical regions of South Africa,Israel and also in the state of Sinaloain Mexico. They require a warm subtropical to tropical climate that is cool but also frost-free or with only very slight winter frosts not below -4°C, and with high summer heat, rainfall, and humidity. Growth is best on well-drained, slightly acidic soils rich in organic matter. A wide range of cultivars is available, with early and late maturing forms suited to warmer and cooler climates respectively. They are also grown as an ornamental tree as well as for their fruit.
Lychees are commonly sold fresh in
Vietnamese, Chinese and Asian markets, and in recent years, also widely in supermarketsworldwide. The red rind turns dark brown when the fruit is refrigerated, but the taste is not affected. It is also sold canned year-round. The fruit can be dried with the rind intact, at which point the flesh shrinks and darkens.
According to folklore, a lychee tree that is not producing much fruit can be girdled, leading to more fruit production.
There are many different
cultivars of lychee (lizhi), of which two are considered to be the most sought-after.
The "Prestigious Cultivars"
* Sweet Osmanthus Flavour (gua mei, 桂味): Named because of the
Sweet Osmanthusflavour it contains, this lychee has light red shells, which contains sharp edges. The fruits are described as crispy and sweet. There is a related cultivar, called "Yatou Green" (yatoulü, 鴨頭綠). The shell of this cultivar has dark green spots.
* Glutinous Rice Ball (nuomici, 糯米糍): Named after its thick fruit flesh and sweet (some described the taste as close to honey) flavours. The fresh red shells are not sharp and hard, and the seeds from this cultivar are noticeably smaller than others. Some fruits from this cultivar are seedless.
"Vải thiều" is a well-known cultivar in Vietnam. It roots in Thanh Ha district,
Hai Duong provinceand recently exists in Luc Ngan district, Bac Giang province. The fruit is notable for its small globe, red shell, tiny or no seed, very sweet taste and special favour.
Other notable cultivars
*Black Leaves (黑葉): This cultivar matures less than others, and has big meats and seeds. The shell exhibits a dark red tint.
*Huaizhi (懷枝): Literally "Branches [of fruit] in the arms of [a person] ", this lychee supposedly received its name when a government official toured Lingnan (modern day Canton) and placed within his arms lychee branches gifted by local villagers.
*March Red (sanyuehong, 三月紅): This lychee matures the earliest, and are usually available annually around March. This particular type has a more subtle fragrance and is sweeter than most.
*The Concubine Smiles (feizixiao, 妃子笑): Famed as the cultivar of lychee
Emperor Xuanzong of Tangbrought from the edges of the Tang empire to cheer up Yang Guifei, this lychee matures earlier than others, and has a very light red tint on its shells.
*The Jade Purse (yuhebao, 玉荷包): Named because of its large fruits and the thick flesh within. The seed is small in this cultivar.
Name in different languages

Middle Chinese. This name in various forms is used throughout South and East Asia.
Lychee in space
The first lychee in space was launched aboard the
Bigelow Aerospacespacecraft " Genesis II" on June 28, 2007as part of the private aerospace firm's "Fly Your Stuff" program. Guy Pignolet de Pluton, a professor at Université de la Réunionin Sainte-Rose, Réunion, provided the lychee which has been imaged on Bigelow Aerospace's website.cite web |url=http://www.science-sainte-rose.net/letchi/Le%20Letchi%20en%20orbite%20et%20dans%20la%20presse.pdf |title=Un letchi dans l’espace |work=Le Journal de L'ile "via" Science-Sainte-Rose.net |first=Alain |last=Dupuis |date=2007-05-26 |accessdate=2008-05-15|format=PDF]
