Celtis australis, the European nettle tree, Mediterranean hackberry, lote tree, or honeyberry, [3] is a deciduous tree native to Southern Europe, North Africa, and Asia Minor. The tree was introduced to England in 1796. [4]
The tree can grow to 25 m in height, though 10 m is more common in cooler climates. The bark is smooth and grey, almost elephantine. [5]
The alternate leaves are narrow and sharp-toothed, rugose above and tomentose below, 5–15 cm long and dark grey/green throughout the year, fading to a pale yellow before falling in autumn.
The apetalous wind-pollinated flowers are perfect (hermaphrodite, having both male and female organs), small and green, either singly or in small clusters.
The fruit is a small, dark-purple berry-like drupe, 1 cm wide, hanging in short clusters. They are edible and are extremely popular with birds and other wildlife.
Celtis australis is supposed to have been the Lotus of the ancients, whose fruit Herodotus, Dioscorides, and Theophrastus describe as sweet, pleasant, and wholesome. Homer has Ulysses refer to the "Lotus-eaters" and the "lotus" in Odyssey, Book IX. [6]
It is often planted as an ornamental as it is long-living and resistant to air pollution. The fruit of this tree is sweet and edible, and can be eaten raw or cooked. The leaves and fruit are astringent, lenitive, and stomachic. Decoction of both leaves and fruit is used in the treatment of amenorrhoea, heavy menstrual and inter-menstrual bleeding, and colic. The decoction can also be used to astringe the mucous membranes in the treatment of diarrhea, dysentery, and peptic ulcers. A yellow dye is obtained from the bark. The wood is very tough, pliable, durable, and widely used by turners; the flexible, thin shoots are used as walking sticks.
The plant prefers light well-drained (sandy) and medium (loamy) soils, including those nutritionally poor; it can tolerate drought but not shade. The Mediterranean climate is especially suitable for the plant but it can tolerate colder climate (USDA Zone 7B). An article on Nettle tree cultivation is brought down in Ibn al-'Awwam's 12th-century agricultural work, Book on Agriculture. [7]
In different countries, Celtis australis is known under the following common names:
Trade names are: nettle wood, brimji. [8]
A large specimen planted in 1550 stands before the church in the village perché of Fox-Amphoux in the Provence region of southern France. The tree was 18 m in height with a circumference at breast height of 5 m in 2013. [9] In Islamic tradition, hackberry trees are considered holy and amulets made from their wood are employed to exorcise demons. The hackberry trees on the Temple Mount in Jerusalem are said to be the oldest in the world. [10]
The fruit and its effects are described in Tennyson's poem The Lotos-Eaters.
The leaves of Celtis australis are a rich source of flavonoid C-glycosides. [11] [12] Young leaves of Celtis australis from Northern Italy were found to contain the highest amounts of phenolics per gram dry weight. Amounts rapidly decreased until mid-May and after this date the level of phenolics fluctuated but showed no discernible trend. This general trend of high amounts of phenolics in the early growing season and a fast decline affected both caffeic acid derivatives and flavonoids. [13]
The Ulmaceae are a family of flowering plants that includes the elms, and the zelkovas. Members of the family are widely distributed throughout the north temperate zone, and have a scattered distribution elsewhere except for Australasia.
Celtis is a genus of about 60–70 species of deciduous trees, commonly known as hackberries or nettle trees, in the hemp family Cannabaceae. It has a cosmopolitan distribution.
Trema is a genus of about 15 species of evergreen trees closely related to the hackberries (Celtis), occurring in subtropical and tropical regions of southern Asia, northern Australasia, Africa, South and Central America, and parts of North America. They are generally small trees, reaching 10–20 m (33–66 ft) tall.
Honeyberry or honey berry is a common name for the edible fruits of several plants and may refer to:
Leontodon is a genus of plants in the tribe Cichorieae within the family Asteraceae, commonly known as hawkbits.
Diospyros lotus, with common names date-plum,Caucasian persimmon, or lilac persimmon, is a widely cultivated species of the genus Diospyros, native to temperate Asia and southeast Europe. Its English name derives from the small fruit, which have a taste reminiscent of both plums and dates. It is among the oldest plants in cultivation.
Celtis occidentalis, commonly known as the common hackberry, is a large deciduous tree native to North America. It is also known as the nettletree, sugarberry, beaverwood, northern hackberry, and American hackberry. It is a moderately long-lived hardwood with a light-colored wood, yellowish gray to light brown with yellow streaks.
Celtis laevigata is a medium-sized tree native to North America. Common names include sugarberry, southern hackberry, or in the southern U.S. sugar hackberry or just hackberry.
The Chinese Elm cultivar Ulmus parvifolia 'Glory' is one of the early American selections, best known for its winter hardiness.
Fox-Amphoux is a commune in the Var department in the Provence-Alpes-Côte d'Azur region in south-eastern France.
Polygonia comma, the eastern comma, is a North American butterfly in the family Nymphalidae, subfamily Nymphalinae.
Celtis paniculata, commonly known as tripewood, silky keltis, silky celtis, native hackberry, native celtis, Investigator tree or whitewood, is a rainforest tree native to parts of Malesia, Melanesia and Australia.
Arnoseris is a monotypic genus of flowering plants in the family Asteraceae.
Celtis sinensis is a species of flowering plant in the hemp family, Cannabaceae, that is native to slopes in East Asia.
Cannabaceae is a small family of flowering plants, known as the hemp family. As now circumscribed, the family includes about 170 species grouped in about 11 genera, including Cannabis (hemp), Humulus (hops) and Celtis (hackberries). Celtis is by far the largest genus, containing about 100 species.
Celtis reticulata, with common names including netleaf hackberry, western hackberry, Douglas hackberry, netleaf sugar hackberry, palo blanco, and acibuche, is a small- to medium-sized deciduous tree native to western North America.
Celtis africana, the white stinkwood, is a deciduous tree in the family Cannabaceae. Its habit ranges from a tall tree in forest to a medium-sized tree in bushveld and open country, and a shrub on rocky soil. It occurs in Yemen and Somaliland and over large parts of Africa south of the Sahara. It is a common tree in the south and east of southern Africa, where the odour given off by freshly-cut green timber is similar to that of Ocotea bullata or black stinkwood.
Trema orientale is a species of flowering tree in the hemp family, Cannabaceae. It is known by many common names, including charcoal-tree, Indian charcoal-tree, pigeon wood, Oriental trema, and in Hawaii, where it has become naturalized, gunpowder tree, or nalita. It has a near universal distribution in tropical and warm temperate parts of the Old World, with a range extending from South Africa, through the Middle East, the Indian subcontinent and southern China to Southeast Asia and Australia.
Celtis timorensis, commonly known as stinkwood or stinking wood, is a species of flowering plant in the family Cannabaceae that grows in tropical Asia. The specific epithet comes from the name of the island of Timor, the locality of the type collection. The most notable characteristic of the tree is the strong excrement odour that it emits from the bark and sap, which pervades the surrounding forest. This is due to the presence of the malodorous organic compound skatole. In Thailand, it therefore known as kæ̂ng k̄hī̂ phrar̀wng or mị̂ chĕd tūd phrar̀wng which means 'wipe the bottom timber'. Thai legend has it that Phra Ruang wiped his buttocks with it. In Sri Lanka the heartwood of the tree is used as a traditional ayurvedic medicine against syphilis, chickenpox, and measles.
Trema lamarckianum, Lamarck's trema, West Indian nettle tree, or pain-in-the-back is a plant species in the genus Trema of the family Cannabaceae. It is a small evergreen shrub that is native of Florida and the West Indies. It has several common names such as pain-in-back, cabrilla and Lamarck trema. It is 6 m tall growing all year.
