Tilia is a genus of about 30 species of trees or bushes, native throughout most of the temperate Northern Hemisphere. The tree is known as linden for the European species, and basswood for North American species. [1] [2] In Great Britain and Ireland they are commonly called lime trees, although they are not related to the citrus lime. The genus occurs in Europe and eastern North America, but the greatest species diversity is found in Asia. Under the Cronquist classification system, this genus was placed in the family Tiliaceae, but genetic research summarised by the Angiosperm Phylogeny Group has resulted in the incorporation of this genus, and of most of the previous family, into the Malvaceae.
Tilia 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. [3] [4] [5]
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, 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 the result is a dense head of abundant foliage. [6]
The leaves of all Tilia species are heart-shaped, and most are asymmetrical. The tiny, pea-like fruit hangs attached to a ribbon-like, greenish-yellow bract whose apparent purpose is to launch the ripened seed clusters just a little beyond the parent tree. The flowers of the European and American Tilia species are similar, except the American ones bear 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. [6]
This list comprises 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.[ citation needed ]
The genus is generally called "lime" or "linden" in Britain [7] and "linden", "lime", or "basswood" in North America. [2]
"Lime" 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 [8] /German Linde, plural Linden), cognate to Latin lentus "flexible" and Sanskrit latā "liana". Within Germanic languages, English "lithe" and Dutch [9] /German lind for "lenient, yielding" are from the same root.
"Linden" was originally 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 [8] and German.[ citation needed ] 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 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 the trees can quickly become coated with a film of the syrup ("honeydew") thus dropped from higher up. The ant/aphid "farming" process does not appear to cause any serious damage to the trees.
The linden is recommended as an ornamental tree when a mass of foliage or a deep shade is desired. [6] It produces fragrant and nectar-producing flowers and is an important honey plant for beekeepers, giving rise to a pale but richly flavoured monofloral honey. In European and North American herbal medicine, the flowers are also used for herbal teas and tinctures. The flowers are used for herbal tea in the winter in the Balkans. In China, dried Tilia flowers are also used to make tea. [10]
In English landscape gardens, avenues of linden trees were fashionable, especially during the late 17th and early 18th centuries. Many country houses have a surviving "lime avenue" or "lime walk", the example at Hatfield House was planted between 1700 and 1730. [11] 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. [12]
Linden trees produce soft and easily worked timber, which has very little grain and a density of 560 kg/m3. [13] It was often used by Germanic tribes for constructing shields. It is a popular wood for model building and for intricate carving. 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 the sculptor Grinling Gibbons [14] (1648–1721). The wood is used in marionette- and puppet-making and -carving. 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 [update] . In China, it was also widely used in carving or furniture, interior decorating, handicrafts, etc. [10]
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 a material for drum shells, both to enhance their sound and for their aesthetics.[ citation needed ]
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.[ citation needed ]
In China, 冻蘑/"dongmo" grows well on decomposing logs of Tilia trees in the old-growth forest; [10] 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 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. [15]
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. [16]
Known in the trade as basswood, particularly in North America, its name originates from the inner fibrous bark of the tree, known as bast. A strong [17] 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 was preferred for clothing there during the Bronze Age. [18] The Manchu people in the mountains of Northeast China made ropes, baskets, raincoats, large fishing nets, and guide lines for gunpowder from the bast. [19] Similar fibres obtained from other plants are also called bast: see Bast fibre.
Tilia is a high-quality wild honey plant. In China, "椴树蜜/Tilia honey" is produced in the northeast region. White in color, it 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. [20] ). [21] "Tilia honey" mainly comes from Tilia amurensis and Tilia mandshurica . [21] "Tilia honey" and southern "longan honey" and "lychee honey" are called "China's three famous honeys". [10] "Tilia honey", "rape honey" and "black acacia honey" are the three most productive honeys in China. [22]
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. [23]
The nectar contains a major secondary metabolite with the trivial name tiliaside (1-[4-(1-hydroxy-1-methylethyl)-1,3-cyclohexadiene-1-carboxylate]-6-O-β-D-glucopyranosyl-β-D-glucopyranose) which is transformed in the gut of bumblebees to the aglycone (i.e., the gentiobiose group is cleaved) which is bioactive against a common and debilitating gut parasite of bumblebees, Crithidia bombi. This naturally occurring compound may support bees to manage the burden of disease - one of the major contributors to pollinator decline. [24]
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. [25] Usually, the double-flowered species are used to make perfumes.[ citation needed ] The leaf buds and young leaves are also edible raw. [26] [27]
Tilia species are used as food plants by 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. [28] In the courtyard of the Imperial Castle at Nuremberg is a Tilia, which by tradition recounted in 1900, was planted by the Empress Cunigunde, the wife of Henry II of Germany circa 1000. The Tilia of Neuenstadt am Kocher in Baden-Württemberg, Germany, was estimated at 1000 years old when it fell. [6] The Alte Linde tree of Naters, Switzerland, is mentioned in a document in 1357 and described by the writer at that time as already magnam (large). A plaque at its foot mentions that in 1155, a linden tree was already on this spot. The Najevnik linden tree (Slovene : Najevska lipa), a 700-year-old T. cordata, is the thickest tree in Slovenia. [29] Next to the 英華殿/Yinghua Temple in the Forbidden City in Beijing, there are two Tilia trees planted by Empress Dowager Li, the biological mother of Wanli Emperor about five hundred years ago. [30]
Linden may refer to:
Tilia cordata, the small-leaved lime or small-leaved linden, is a species of tree in the family Malvaceae, native to much of Europe. Other common names include little-leaf or littleleaf linden, or traditionally in South East England, pry or pry tree. Its range extends from Britain through mainland Europe to the Caucasus and western Asia. In the south of its range it is restricted to high elevations.
Tilia platyphyllos, the large-leaved lime or large-leaved linden, is a species of flowering plant in the family Malvaceae (Tiliaceae). It is a deciduous tree, native to much of continental Europe as well as southwestern Great Britain, growing on lime-rich soils. The common names largeleaf linden and large-leaved linden are in standard use throughout the English-speaking world except in the British Isles, where it is known as large-leaved lime. The name "lime", possibly a corruption of "line" originally from "lind", has been in use for centuries and also attaches to other species of Tilia. It is not, however, closely related to the lime fruit tree, a species of citrus.
Fiber crops are field crops grown for their fibers, which are traditionally used to make paper, cloth, or rope.
Tilia americana is a species of tree in the family Malvaceae, native to eastern North America, from southeast Manitoba east to New Brunswick, southwest to northeast Oklahoma, southeast to South Carolina, and west along the Niobrara River to Cherry County, Nebraska. It is the sole representative of its genus in the Western Hemisphere, assuming T. caroliniana is treated as a subspecies or local ecotype of T. americana. Common names include American basswood and American linden.
Tilia × europaea, generally known as the European lime, common lime or common linden, is a naturally occurring hybrid between Tilia cordata and Tilia platyphyllos. It occurs in the wild in Europe at scattered localities wherever the two parent species are both native. It is not closely related to the lime fruit tree, a citrus species.
Tilia tomentosa, known as silver linden in the US and silver lime in the UK, is a species of flowering plant in the family Malvaceae, native to southeastern Europe and southwestern Asia, from Romania and the Balkans east to western Turkey, occurring at moderate altitudes.
Eriophyes tiliae is a mite that forms the lime nail gall or bugle gall. It develops in a chemically induced gall; an erect, oblique or curved distortion rising up from the upper surface of the leaves of the lime (linden) trees, such as the large-leaved lime tree Tilia platyphyllos, the common lime tree Tilia × europaea, etc.
Bucculatrix thoracella, the lime bent-wing, is species of moth in the family Bucculatricidae, and was first described in 1794 by Carl Peter Thunberg as Tinea thoracella. It is found throughout Europe with exception of Ireland and the Balkan Peninsula, and in Japan, where it occurs on the islands of Hokkaido and Honshu.
Oxycarenus lavaterae, common name lime seed bug, is a species of ground bug of the family Lygaeidae, subfamily Oxycareninae.
Cordata, a Latin adjective meaning heart-shaped, may refer to:
Upper Wye Gorge is a Site of Special Scientific Interest (SSSI), noted for its biological and geological characteristics, around Symonds Yat in the Wye Valley on the Wales–England border. The site is listed in the "Forest of Dean Local Plan Review" as a Key Wildlife Site (KWS).
Tilia chinensis is a species of lime or linden tree that is endemic to China. It flowers in July or August when honey bees collect honey from its flowers. Especially famous is honey taken from the Chinese linden flowers in Changbai Mountain.
The Bardney Limewoods, part of the Lincolnshire Limewoods National Nature Reserve is a collection of small woodlands near Bardney in Lincolnshire. The reserve includes about half the Limewoods in the area. Cocklode Wood, part of the Bardney Limewoods, is the best surviving spread of medieval limes in England.
Tilia mongolicaMaxim., commonly known as Mongolian lime, is a tree native to mountains of the northern China, growing up to elevations of 1200–2200 m.
The lime tree, or linden, (Tilia) is important in the mythology, literature, and folklore of a number of cultures.
Tilia carolinianaMill. is a species of tree in the family Malvaceae native to the southern and south-eastern states of the U.S., and Mexico.
Tilia japonica, the Japanese lime or Japanese linden, is a species of Tilia native to eastern China and Japan, preferring to grow in mountains up to 2000 m. It superficially resembles the better-known Tilia cordata, the small-leaved lime, and was originally described as Tilia cordata var. japonica. It differs from T. cordata in having 164 chromosomes instead of 82, and by some subtle differences in leaf and flower morphology. T. japonica inflorescences consistently have 5 staminodes, which is a reliable trait distinguishing it from T. cordata and T. amurensis. Recent studies indicate T.japonica to play an important role in maintaining the ectomycorrhizal networks in local forests it grows in Japan.
Tilia amurensis, commonly known as the Amur lime or Amur linden, is a species of Tilia native to eastern Asia. It differs from the better-known Tilia cordata in having somewhat smaller leaves, bracts and cymes. It is an important timber tree in Russia, China and Korea, and is occasionally planted as a street tree in cities with colder climates.
