Especially in Germany, it was the classic wood for sculpture from the Middle Ages onwards and is the material for the elaborate altarpieces of Veit Stoss , Tilman Riemenschneider , and many others. In England, it was the favoured medium of
290-458: A high quantity of citric acid , which with other organic acids including ascorbic acid (vitamin C) give them their characteristic sharp taste. Citrus fruits are diverse in size and shape, as well as in color and flavor, reflecting their biochemistry; for instance, grapefruit is made bitter-tasting by a flavanone, naringin . Most commercial citrus cultivation uses trees produced by grafting
348-576: A linear furanocoumarin derived from psoralen . This claim has been confirmed for lime and bergamot . In particular, bergamot essential oil has a higher concentration of bergapten (3–3.6 g/kg) than any other Citrus -based essential oil. A systematic review indicates that citrus fruit consumption is associated with a 10% reduction of risk for developing breast cancer. Many citrus fruits, such as oranges , tangerines , grapefruits , and clementines , are generally eaten fresh. They are typically peeled and can be easily split into segments. Grapefruit
406-639: A material for drum shells, both to enhance their sound and for their aesthetics. Linden wood is also the material of choice for window blinds and shutters. Real-wood blinds are often made from this lightweight but strong and stable wood, which is well suited to natural and stained finishes. In China, 冻蘑/"dongmo" grows well on decomposing logs of Tilia trees in the old-growth forest ; therefore, people use logs of Tilia trees to cultivate S. edulis and even Black fungus or shiitake mushrooms with excellent results. Currently, "椴木黑木耳/ Tilia -logs-black fungus" or "椴木香菇/ Tilia -logs-shiitake mushrooms" has become

The flowers are used for herbal tea in the winter in the Balkans. In China, dried Tilia flowers are also used to make tea. In English landscape gardens , avenues of linden trees were fashionable, especially during the late 17th and early 18th centuries. Many country houses have
522-518: A petal-like scale among their stamens and the European varieties are devoid of these appendages. All of the Tilia species may be propagated by cuttings and grafting, as well as by seed. They grow rapidly in rich soil, but are subject to the attack of many insects. Tilia is notoriously difficult to propagate from seed unless collected fresh in fall. If allowed to dry, the seeds go into a deep dormancy and take 18 months to germinate. This list comprises
580-491: A small number of core ancestral species, including the citron, pomelo, and mandarin. Natural and cultivated citrus hybrids include commercially important fruit such as oranges, grapefruit , lemons, limes, and some tangerines . The multiple hybridisations have made the taxonomy of Citrus complex. Apart from these core species, Australian limes and the recently discovered mangshanyegan are grown. Kumquats and Clymenia spp. are now generally considered to belong within
638-570: A surviving "lime avenue" or "lime walk", the example at Hatfield House was planted between 1700 and 1730. The fashion was derived from the earlier practice of planting lindens in lines as shade trees in Germany, the Netherlands, Belgium and northern France. Most of the trees used in British gardens were cultivars propagated by layering in the Netherlands. Linden trees produce soft and easily worked timber, which has very little grain and

#1732773145447696-539: A term for a method of cultivating black fungus and shiitake mushrooms and "椴木/ Tilia -logs" no longer exclusively refers to Tilia tree wood but also to other woods suitable for black fungus or shiitake mushrooms cultivation. In Russian, "linden-made" (липовый, lipoviy ) is a term for forgery, due to the popularity of the material for making forged seals in the past centuries. Known in the trade as basswood, particularly in North America, its name originates from
754-460: A wasp on one of the fruits. The impressionist Edouard Manet depicted a lemon on a pewter plate. In modern art, Arshile Gorky painted Still Life with Lemons in the 1930s. Citrus fruits "were the clear status symbols of the nobility in the ancient Mediterranean", according to the paleoethnobotanist Dafna Langgut. In Louisa May Alcott 's 1868 novel Little Women , the character Amy March states that "It's nothing but limes now, for everyone
812-460: A wide range of appearance and fruit flavors. The large citrus fruit of today evolved originally from small, edible berries over millions of years. Citrus species began to diverge from a common ancestor about 15 million years ago, at about the same time that Severinia (such as the Chinese box orange ) diverged from the same ancestor. About 7 million years ago, the ancestors of Citrus split into
870-485: Is a genus of flowering trees and shrubs in the family Rutaceae . Plants in the genus produce citrus fruits , including important crops such as oranges , mandarins , lemons , grapefruits , pomelos , and limes . Citrus is native to South Asia, East Asia, Southeast Asia, Melanesia , and Australia. Indigenous people in these areas have used and domesticated various species since ancient times. Its cultivation first spread into Micronesia and Polynesia through
928-463: Is an altered form of Middle English lind , in the 16th century also line , from Old English feminine lind or linde , Proto-Germanic *lindō (cf. Dutch /German Linde, plural Linden ), cognate to Latin lentus "flexible" and Sanskrit latā " liana ". Within Germanic languages , English "lithe" and Dutch /German lind for "lenient, yielding" are from the same root. "Linden" was originally
986-415: Is basswood, derived from bast , the name for the inner bark (see Uses , below). Teil is an old name for the lime tree. Aphids are attracted by the rich supply of sap, and are in turn often "farmed" by ants for the production of the sap, which the ants collect for their own use, and the result can often be a dripping of excess sap onto the lower branches and leaves, and anything else below. Cars left under
1044-725: Is called "white honey" or "snow honey". Heilongjiang is well-known throughout the country for producing high-quality " Tilia honey": Heilongjiang not only has lush Tilia trees, but also a rare and excellent bee species - " 东北黑蜂/Northeast Black Bee " to collect honey（ Raohe County is the location of the national "东北黑蜂自然保护区/Northeast Black Bee Nature Reserve". It is the only nature reserve for bees in Asia. ). " Tilia honey" mainly comes from Tilia amurensis and Tilia mandshurica . " Tilia honey" and southern " longan honey" and " lychee honey" are called "China's three famous honeys". " Tilia honey", " rape honey" and " black acacia honey " are
1102-477: Is more commonly halved and eaten out of the skin with a spoon. Lemonade is a popular beverage prepared by diluting the juice and adding sugar. Lemon juice is mixed in salad dressings and squeezed over fruit salad to stop it from turning brown: its acidity suppresses oxidation by polyphenol oxidase enzymes. A variety of flavours can be derived from different parts and treatments of citrus fruits. The colourful outer skin of some citrus fruits, known as zest ,
1160-476: Is the only known ectomycorrhizal genus in the family Malvaceae . Studies of ectomycorrhizal relations of Tilia species indicate a wide range of fungal symbionts and a preference toward Ascomycota fungal partners. Tilia species are mostly large, deciduous trees, reaching typically 20 to 40 m (65 to 130 ft) tall, with oblique-cordate (heart-shaped) leaves 6 to 20 cm ( 2 + 1 ⁄ 4 to 7 + 3 ⁄ 4 in) across. As with elms ,
1218-580: Is used as a flavouring in cooking. The whole of the bitter orange (and sometimes other citrus fruits) including the peel with its essential oils is cooked with sugar to make marmalade . By the 17th century, orangeries were added to great houses in Europe, both to enable the fruit to be grown locally and for prestige, as seen in the Versailles Orangerie . Some modern hobbyists grow dwarf citrus in containers or greenhouses in areas where

#17327731454471276-698: The Austronesian expansion ( c. 3000 –1500 BCE). Later, it was spread to the Middle East and the Mediterranean ( c. 1200 BCE ) via the incense trade route , and from Europe to the Americas. Renowned for their highly fragrant aromas and complex flavor, citrus are among the most popular fruits in cultivation. With a propensity to hybridize between species, making their taxonomy complicated, there are numerous varieties encompassing
1334-740: The Philippines . This was followed by the spread of citrus species into Taiwan and Japan in the Early Pliocene (5.33 to 3.6 mya ), resulting in the tachibana orange ( C. tachibana ); and beyond the Wallace Line into Papua New Guinea and Australia during the Early Pleistocene (2.5 million to 800,000 years ago), where further speciation events created in the Australian limes . A fossil leaf from
1392-640: The Pliocene of Valdarno , Italy is described as † Citrus meletensis . In China, fossil leaf specimens of † Citrus linczangensis have been collected from late Miocene coal-bearing strata of the Bangmai Formation in Yunnan province. C. linczangensis resembles C. meletensis in having an intramarginal vein, an entire margin, and an articulated and distinctly winged petiole . Many cultivated Citrus species are natural or artificial hybrids of
1450-665: The citron ( C. medica ) or a conifer tree ( Thuja ). The Latin word is related to the ancient Greek word for the cedar of Lebanon , κέδρος ( kédros ), perhaps from a perceived similarity of the smell of citrus leaves and fruit with that of cedar. Citrus plants are large shrubs or small to moderate-sized trees, reaching 5–15 m (16–49 ft) tall, with spiny shoots and alternately arranged evergreen leaves with an entire margin. The flowers are solitary or in small corymbs , each flower 2–4 cm (0.79–1.57 in) diameter, with five (rarely four) white petals and numerous stamens; they are often very strongly scented, due to

1566-671: The larvae of some Lepidoptera ; see List of Lepidoptera that feed on Tilia . In Europe, some linden trees reached considerable ages. A coppice of T. cordata in Westonbirt Arboretum in Gloucestershire is estimated to be 2,000 years old. In the courtyard of the Imperial Castle at Nuremberg is a Tilia , which by tradition recounted in 1900, was planted by the Empress Cunigunde ,
1624-655: The Mediterranean by Arab traders around the 10th century CE. Sweet oranges were brought to Europe by the Genoese and Portuguese from Asia during the 15th to 16th century. Mandarins were not introduced until the 19th century. Oranges were introduced to Florida by Spanish colonists. In cooler parts of Europe, citrus fruit was grown in orangeries starting in the 17th century; many were as much status symbols as functional agricultural structures. The generic name Citrus originates from Latin , where it denoted either
1682-522: The adjective, "made from linwood or lime-wood" (equivalent to "wooden" or "oaken"); from the late 16th century, "linden" was also used as a noun, probably influenced by translations of German romance, as an adoption of Linden , the plural of Linde in Dutch and German. Neither the name nor the tree is related to Citrus genus species and hybrids that go by the same name, such as Key limes ( Citrus × aurantifolia ). Another common name used in North America
1740-412: The burden of disease - one of the major contributors to pollinator decline. A beverage made from dried linden leaves and flowers is brewed and consumed as a folk medicine and relaxant in many Balkan countries, including Serbia and Greece . Usually, the double-flowered species are used to make perfumes. The leaf buds and young leaves are also edible raw. Tilia species are used as food plants by
1798-529: The center of origin of the genus Citrus is likely the southeast foothills of the Himalayas , in a region stretching from eastern Assam , northern Myanmar , to western Yunnan . It diverged from a common ancestor with Poncirus trifoliata . A change in climate conditions during the Late Miocene (11.63 to 5.33 mya ) resulted in a sudden speciation event . The species resulting from this event include

This threatens production in Florida, California, and worldwide. Citrus groves are attacked by parasitic Nematodes including citrus ( Tylenchulus semipenetrans ) and sheath nematodes ( Hemicycliophora spp.). Citrus plants can develop
1972-432: The deficiency condition chlorosis , characterized by yellowing leaves. The condition is often caused by an excessively high pH ( alkaline soil ), which prevents the plant from absorbing nutrients such as iron, magnesium , and zinc needed to produce chlorophyll . Some Citrus species contain significant amounts of furanocoumarins . In humans, some of these act as strong photosensitizers when applied topically to
2030-415: The desired fruiting cultivars onto rootstocks selected for disease resistance and hardiness. The trees are not generally frost hardy. They thrive in a consistently sunny, humid environment with fertile soil and adequate water. The colour of citrus fruits only develops in climates with a ( diurnal ) cool winter. In tropical regions with no winter at all, citrus fruits remain green until maturity, hence
2088-523: The earliest evidence are seeds recovered from the Hala Sultan Tekke site of Cyprus , dated to around 1200 BCE. Other archaeobotanical evidence includes pollen from Carthage dating back to the 4th century BCE; and carbonized seeds from Pompeii dated to around the 3rd to 2nd century BCE. The earliest complete description of the citron was written by Theophrastus , c. 310 BCE . Lemons, pomelos, and sour oranges were introduced to
2146-756: The early 21st century mainly by the increase in cultivation areas, improvements in transportation and packaging, rising incomes and consumer preference for healthy foods. In 2019–20, world production of oranges was estimated to be 47.5 million tonnes, led by Brazil, Mexico, the European Union, and China as the largest producers. Among the diseases of citrus plantations are citrus black spot (a fungus), citrus canker (a bacterium), citrus greening (a bacterium, spread by an insect pest), and sweet orange scab (a fungus, Elsinöe australis ). Citrus plants are liable to infestation by ectoparasites which act as vectors to plant diseases: for example, aphids transmit
2204-456: The exact number of species is uncertain, as many of the species can hybridise readily, both in the wild and in cultivation. They are hermaphroditic , having perfect flowers with both male and female parts, pollinated by insects. The Tilia 's sturdy trunk stands like a pillar and the branches divide and subdivide into numerous ramifications on which the twigs are fine and thick. In summer, these are profusely clothed with large leaves and
2262-761: The genus Citrus associated with modern Citrus cultivars are the mandarin orange , pomelo , and citron . Almost all of the common commercially important citrus fruits (sweet oranges, lemons, grapefruit, limes, and so on) are hybrids between these three species, their main progenies, and other wild Citrus species within the last few thousand years. Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia , Near Oceania , and northeastern and central Australia. Domestication of citrus species involved much hybridization and introgression , leaving much uncertainty about when and where domestication first happened. A genomic, phylogenic, and biogeographical analysis by Wu et al. (2018) has shown that
2320-555: The genus Citrus . The false oranges, Oxanthera from New Caledonia , have been transferred to the Citrus genus on phylogenetic evidence. The earliest introductions of citrus species by human migrations was during the Austronesian expansion ( c. 3000 –1500 BCE), where Citrus hystrix , Citrus macroptera , and Citrus maxima were among the canoe plants carried by Austronesian voyagers eastwards into Micronesia and Polynesia . The citron ( Citrus medica )
2378-587: The inner fibrous bark of the tree, known as bast. A strong fibre is obtained from the tree by peeling off the bark and soaking it in water for a month, after which the inner fibres can be easily separated. Bast obtained from the inside of the bark of the Tilia japonica tree has been used by the Ainu people of Japan to weave their traditional clothing, the attus . Excavations in Britain have shown that lime tree fibre

2436-453: The locules, which provide nourishment to the fruit as it develops. The genus is commercially important with cultivars of many species grown for their fruit. Some cultivars have been developed to be easy to peel and seedless, meaning they are parthenocarpic . The fragrance of citrus fruits is conferred by flavonoids and limonoids in the rind. The flavonoids include various flavanones and flavones . The carpels are juicy; they contain
2494-557: The main genus, Citrus , and the genus Poncirus (such as the trifoliate orange ), which is closely enough related that it can still be hybridized with all other citrus and used as rootstock. These estimates are made using genetic mapping of plant chloroplasts . A DNA study published in Nature in 2018 concludes that the genus Citrus evolved in the foothills of the Himalayas , in the area of Assam (India), western Yunnan (China), and northern Myanmar . The three ancestral species in
2552-437: The most widely accepted species, hybrids, and cultivars. The Latin tilia is cognate to Greek πτελέᾱ, ptelea , " elm tree ", τιλίαι, tiliai , " black poplar " ( Hes. ), ultimately from a Proto-Indo-European word *ptel-ei̯ā with a meaning of "broad" (feminine); perhaps "broad-leaved" or similar. The genus is generally called "lime" or "linden" in Britain and "linden", "lime", or "basswood" in North America. "Lime"
2610-410: The pericarp is the mesocarp, which in citrus fruits consists of the white, spongy albedo or pith. The innermost layer of the pericarp is the endocarp. This surrounds a variable number of carpels , shaped as radial segments. The seeds, if present, develop inside the carpels. The space inside each segment is a locule filled with juice vesicles , or pulp. From the endocarp, string-like "hairs" extend into
2668-403: The presence of essential oil glands. The fruit is a hesperidium , a specialised berry with multiple carpels , globose to elongated, 4–30 cm (1.6–11.8 in) long and 4–20 cm (1.6–7.9 in) diameter, with a leathery rind or "peel" called a pericarp . The outermost layer of the pericarp is an "exocarp" called the flavedo , commonly referred to as the zest . The middle layer of

Having a fine, light grain and being comparatively light in weight, it has been used for centuries for this purpose; despite the availability of modern alternatives, it remains one of the main materials used as of 2015 . In China, it was also widely used in carving or furniture, interior decorating, handicrafts, etc. Ease of working and good acoustic properties also make limewood popular for electric and bass guitar bodies and for wind instruments such as recorders . Percussion manufacturers sometimes use Tilia as
2900-449: The skin, while others interact with medications when taken orally in the grapefruit juice effect . Due to the photosensitizing effects of certain furanocoumarins, some Citrus species cause phytophotodermatitis , a potentially severe skin inflammation resulting from contact with a light-sensitizing botanical agent followed by exposure to ultraviolet light. In Citrus species, the primary photosensitizing agent appears to be bergapten ,
2958-453: The three most productive honeys in China. The dried flowers are mildly sweet and sticky, and the fruit is somewhat sweet and mucilaginous. Linden flower tea has a pleasing taste, due to the aromatic volatile oil found in the flowers. Phytochemicals in the Tilia flowers include flavonoids and tannins with astringent properties. The nectar contains a major secondary metabolite with

This naturally occurring compound may support bees to manage
3132-480: The tropical "green oranges". The terms 'ripe' and 'mature' are widely used synonymously, but they mean different things. A mature fruit is one that has completed its growth phase. Ripening is the sequence of changes within the fruit from maturity to the beginning of decay. These changes involve the conversion of starches to sugars, a decrease in acids, softening, and s change in the fruit's colour. Citrus fruits are non- climacteric and respiration slowly declines and
