76-432: All through its existence the family has had a very lively history, with various authors taking very different views on what should be part of this family. As a result, it is recommended when this name is encountered to check what the author means. However, in the northern temperate regions the name is unambiguous as the only representative is Tilia , the lime or linden . The APG II system , does not recognise this as

152-590: A 700-year-old T. cordata , is the thickest tree in Slovenia . 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. Fabaceae The Fabaceae ( / f ə ˈ b eɪ s i . iː , - ˌ aɪ / ) or Leguminosae , commonly known as the legume , pea , or bean family , are

228-509: A density of 560 kg/m . 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

304-578: A family but submerges it in the Malvaceae sensu lato, which unites the four families Bombacaceae , Malvaceae sensu stricto, Sterculiaceae and Tiliaceae. Modern botanical taxonomy, such as the relevant volume in the Kubitzki series which conforms to APG, treats most of the plants that traditionally constitute the family (see above) in the subfamilies Tilioideae , Brownlowioideae, and Grewioideae within this extended family Malvaceae sensu lato. Cladistically ,

380-533: A large and agriculturally important family of flowering plants . It includes trees , shrubs , and perennial or annual herbaceous plants , which are easily recognized by their fruit ( legume ) and their compound, stipulate leaves. The family is widely distributed, and is the third-largest land plant family in number of species, behind only the Orchidaceae and Asteraceae , with about 765 genera and nearly 20,000 known species. The five largest genera of

456-639: 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

532-492: 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. In English landscape gardens , avenues of linden trees were fashionable, especially during the late 17th and early 18th centuries. Many country houses have

608-565: 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

684-833: A rhizobia species may often infect more than one host species. This means that one plant species may be infected by more than one species of bacteria. For example, nodules in Acacia senegal can contain seven species of rhizobia belonging to three different genera. The most distinctive characteristics that allow rhizobia to be distinguished apart are the rapidity of their growth and the type of root nodule that they form with their host. Root nodules can be classified as being either indeterminate, cylindrical and often branched, and determinate, spherical with prominent lenticels. Indeterminate nodules are characteristic of legumes from temperate climates, while determinate nodules are commonly found in species from tropical or subtropical climates. Nodule formation

760-665: A short hypanthium , usually cup-shaped. There are normally ten stamens and one elongated superior ovary , with a curved style . They are usually arranged in indeterminate inflorescences . Fabaceae are typically entomophilous plants (i.e. they are pollinated by insects ), and the flowers are usually showy to attract pollinators . In the Caesalpinioideae , the flowers are often zygomorphic , as in Cercis , or nearly symmetrical with five equal petals, as in Bauhinia . The upper petal

836-430: A staple, essential as a source of protein. Their ability to fix atmospheric nitrogen reduces fertilizer costs for farmers and gardeners who grow legumes, and means that legumes can be used in a crop rotation to replenish soil that has been depleted of nitrogen . Legume seeds and foliage have a comparatively higher protein content than non-legume materials, due to the additional nitrogen that legumes receive through

912-559: 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

988-448: A synonym of Daphne ). The genus Abatia is assigned to the family Salicaceae sensu lato. The family reached perhaps its widest circumscription in the Bentham & Hooker system : According to APG II system , the current placement of these genera is perhaps mostly in the Malvaceae sensu lato, but with Muntingia moved to family Muntingiaceae , while tribes VI and VII form

1064-532: 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

1140-736: A wide variety of growth forms , including trees, shrubs, herbaceous plants, and even vines or lianas . The herbaceous plants can be annuals, biennials , or perennials, without basal or terminal leaf aggregations. Many Legumes have tendrils. They are upright plants, epiphytes , or vines. The latter support themselves by means of shoots that twist around a support or through cauline or foliar tendrils . Plants can be heliophytes , mesophytes , or xerophytes . The leaves are usually alternate and compound. Most often they are even- or odd- pinnately compound (e.g. Caragana and Robinia respectively), often trifoliate (e.g. Trifolium , Medicago ) and rarely palmately compound (e.g. Lupinus ), in

1216-508: A wide variety of taxa representing the main lineages in the Fabaceae have been found in the fossil record dating from the middle to the late Eocene , suggesting that the majority of the modern Fabaceae groups were already present and that a broad diversification occurred during this period. Therefore, the Fabaceae started their diversification approximately 60 million years ago and the most important clades separated 50 million years ago. The age of

1292-458: 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

1368-415: 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

1444-721: 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

1520-515: Is common throughout the Fabaceae. It is found in the majority of its members that only form an association with rhizobia, which in turn form an exclusive symbiosis with the Fabaceae (with the exception of Parasponia , the only genus of the 18 Ulmaceae genera that is capable of forming nodules). Nodule formation is present in all the Fabaceae sub-families, although it is less common in the Caesalpinioideae. All types of nodule formation are present in

1596-497: Is defined by isoxazolin-5-one derivatives. These compounds occur in particular together with 3-NPA and related derivatives at the same time in the same species, as found in Astragalus canadensis and Astragalus collinus . 3-NPA and isoxazlin-5-one derivatives also occur in many species of leaf beetles (see defense in insects ). Legumes are economically and culturally important plants due to their extraordinary diversity and abundance,

1672-582: Is the innermost one, unlike in the Faboideae . Some species, like some in the genus Senna , have asymmetric flowers, with one of the lower petals larger than the opposing one, and the style bent to one side. The calyx, corolla, or stamens can be showy in this group. In the Mimosoideae , the flowers are actinomorphic and arranged in globose inflorescences. The petals are small and the stamens, which can be more than just 10, have long, coloured filaments, which are

1748-476: 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 ,

1824-516: The Paleogene to become a ubiquitous part of the modern earth's biota , along with many other families belonging to the flowering plants. The Fabaceae have an abundant and diverse fossil record, especially for the Tertiary period. Fossils of flowers, fruit, leaves, wood and pollen from this period have been found in numerous locations. The earliest fossils that can be definitively assigned to

1900-603: The Rosidae clade (as established by the gene molecular phylogeny of rbcL , a gene coding for part of the RuBisCO enzyme in the chloroplast ). This grouping indicates that the predisposition for forming nodules probably only arose once in flowering plants and that it can be considered as an ancestral characteristic that has been conserved or lost in certain lineages. However, such a wide distribution of families and genera within this lineage indicates that nodulation had multiple origins. Of

1976-563: The Tethys seaway during the Palaeogene Period. However, others contend that Africa (or even the Americas ) cannot yet be ruled out as the origin of the family. The current hypothesis about the evolution of the genes needed for nodulation is that they were recruited from other pathways after a polyploidy event. Several different pathways have been implicated as donating duplicated genes to

2052-458: The fruit of these plants, which are called legumes . Fabaceae range in habit from giant trees (like Koompassia excelsa ) to small annual herbs , with the majority being herbaceous perennials. Plants have indeterminate inflorescences, which are sometimes reduced to a single flower. The flowers have a short hypanthium and a single carpel with a short gynophore , and after fertilization produce fruits that are legumes. The Fabaceae have

2128-640: 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 ,

2204-498: The 10 families within the Rosidae, 8 have nodules formed by actinomyces ( Betulaceae , Casuarinaceae , Coriariaceae , Datiscaceae , Elaeagnaceae , Myricaceae , Rhamnaceae and Rosaceae ), and the two remaining families, Ulmaceae and Fabaceae have nodules formed by rhizobia. The rhizobia and their hosts must be able to recognize each other for nodule formation to commence. Rhizobia are specific to particular host species although

2280-549: The Americas and Africa. Recent molecular and morphological evidence supports the fact that the Fabaceae is a single monophyletic family. This conclusion has been supported not only by the degree of interrelation shown by different groups within the family compared with that found among the Leguminosae and their closest relations, but also by all the recent phylogenetic studies based on DNA sequences. These studies confirm that

2356-462: The Fabaceae appeared in the early Palaeocene (approximately 65 million years ago). Representatives of the 3 sub-families traditionally recognised as being members of the Fabaceae – Cesalpinioideae, Papilionoideae and Mimosoideae – as well as members of the large clades within these sub-families – such as the genistoides – have been found in periods later, starting between 55 and 50 million years ago. In fact,

2432-826: The Fabaceae are a monophyletic group that is closely related to the families Polygalaceae , Surianaceae and Quillajaceae and that they belong to the order Fabales . Along with the cereals , some fruits and tropical roots, a number of Leguminosae have been a staple human food for millennia and their use is closely related to human evolution . The family Fabaceae includes a number of plants that are common in agriculture including Glycine max ( soybean ), Phaseolus (beans), Pisum sativum ( pea ), Cicer arietinum ( chickpeas ), Vicia faba ( broad bean ), Medicago sativa ( alfalfa ), Arachis hypogaea ( peanut ), Ceratonia siliqua (carob), Trigonella foenum-graecum ( fenugreek ), and Glycyrrhiza glabra ( liquorice ). A number of species are also weedy pests in different parts of

2508-536: The Fabaceae. Forisome proteins are found in the sieve tubes of Fabaceae; uniquely they are not dependent on ADT . The order Fabales contains around 7.3% of eudicot species and the greatest part of this diversity is contained in just one of the four families that the order contains: Fabaceae. This clade also includes the families Polygalaceae , Surianaceae and Quillajaceae and its origins date back 94 to 89 million years, although it started its diversification 79 to 74 million years ago. The Fabaceae diversified during

2584-708: The Faboideae, even though diversification within each genus was relatively recent. For instance, Astragalus separated from the Oxytropis 16 to 12 million years ago. In addition, the separation of the aneuploid species of Neoastragalus started 4 million years ago. Inga , another genus of the Papilionoideae with approximately 350 species, seems to have diverged in the last 2 million years. It has been suggested, based on fossil and phylogenetic evidence, that legumes originally evolved in arid and/or semi-arid regions along

2660-571: The Mimosoideae and the Caesalpinioideae commonly bipinnate (e.g. Acacia , Mimosa ). They always have stipules , which can be leaf-like (e.g. Pisum ), thorn-like (e.g. Robinia ) or be rather inconspicuous. Leaf margins are entire or, occasionally, serrate . Both the leaves and the leaflets often have wrinkled pulvini to permit nastic movements . In some species, leaflets have evolved into tendrils (e.g. Vicia ). Many species have leaves with structures that attract ants which protect

2736-577: The ability to take nitrogen gas (N 2 ) out of the air and convert it to a form of nitrogen that is usable to the host plant ( NO 3 or NH 3 ). This process is called nitrogen fixation . The legume, acting as a host, and rhizobia , acting as a provider of usable nitrate, form a symbiotic relationship. Members of the Phaseoleae genus Apios form tubers, which can be edible. The flowers often have five generally fused sepals and five free petals . They are generally hermaphroditic and have

2812-518: 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

2888-495: The apex (remaining free at the base), forming a boat-like structure called the keel. The stamens are always ten in number, and their filaments can be fused in various configurations, often in a group of nine stamens plus one separate stamen. Various genes in the CYCLOIDEA (CYC)/DICHOTOMA (DICH) family are expressed in the upper (also called dorsal or adaxial) petal; in some species, such as Cadia , these genes are expressed throughout

2964-429: The basic legume fruit. The Fabaceae are rarely cyanogenic . Where they are, the cyanogenic compounds are derived from tyrosine , phenylalanine or leucine . They frequently contain alkaloids . Proanthocyanidins can be present either as cyanidin or delphinidine or both at the same time. Flavonoids such as kaempferol , quercitin and myricetin are often present. Ellagic acid has never been found in any of

3040-412: 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

3192-620: 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 Fabaceae . Tilia

3268-560: The compound 3-nitropropanoic acid (3-NPA, beta-nitropropionic acid ). The free acid 3-NPA is an irreversible inhibitor of mitochondrial respiration , and thus the compound inhibits the tricarboxylic acid cycle . This inhibition caused by 3-NPA is especially toxic to nerve cells and represents a very general toxic mechanism suggesting a profound ecological importance due to the big number of species producing this compound and its derivatives. A second and closely related class of secondary metabolites that occur in many species of leguminous plants

3344-472: The core of family Elaeocarpaceae and tribe V has been moved to the family Salicaceae sensu lato. The Hutchinson system follows the Bentham & Hooker system rather closely. In the Cronquist system (1981) the family includes some fifty genera, totalling around seven hundred species of trees and shrubs, rarely herbs, with a subcosmopolitan distribution. It may be separated from Malvaceae sensu stricto by

3420-536: The different approaches yielded similar results regarding the relationships between the family's main clades. Following extensive discussion in the legume phylogenetics community, the Legume Phylogeny Working Group reclassified Fabaceae into six subfamilies, which necessitated the segregation of four new subfamilies from Caesalpinioideae and merging Caesapinioideae sensu stricto with the former subfamily Mimosoideae. The exact branching order of

3496-552: The different subfamilies is still unresolved. Polygalaceae ( outgroup ) Surianaceae (outgroup) Quillajaceae (outgroup) Cercidoideae Detarioideae Duparquetioideae Dialioideae Caesalpinioideae Faboideae The Fabaceae are placed in the order Fabales according to most taxonomic systems, including the APG III system . The family now includes six subfamilies: The Fabaceae have an essentially worldwide distribution, being found everywhere except Antarctica and

3572-456: 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

3648-420: The family are Astragalus (over 3,000 species), Acacia (over 1,000 species), Indigofera (around 700 species), Crotalaria (around 700 species), and Mimosa (around 400 species), which constitute about a quarter of all legume species. The c. 19,000 known legume species amount to about 7% of flowering plant species. Fabaceae is the most common family found in tropical rainforests and dry forests of

3724-432: The flower, producing a radially symmetrical flower. The ovary most typically develops into a legume . A legume is a simple dry fruit that usually dehisces (opens along a seam) on two sides. A common name for this type of fruit is a "pod", although that can also be applied to a few other fruit types. A few species have evolved samarae , loments , follicles , indehiscent legumes, achenes , drupes , and berries from

3800-429: The genera or species analysed. Sugars are transported within the plants in the form of sucrose . C3 photosynthesis has been found in a wide variety of genera. The family has also evolved a unique chemistry. Many legumes contain toxic and indigestible substances, antinutrients , which may be removed through various processing methods. Pterocarpans are a class of molecules (derivatives of isoflavonoids ) found only in

3876-452: The high Arctic. The trees are often found in tropical regions, while the herbaceous plants and shrubs are predominant outside the tropics. Biological nitrogen fixation (BNF, performed by the organisms called diazotrophs ) is a very old process that probably originated in the Archean eon when the primitive atmosphere lacked oxygen . It is only carried out by Euryarchaeota and just 6 of

Both pathways include the same type of enzymes, pectin-degrading cell wall enzymes. The enzymes needed to reduce nitrogen, nitrogenases, require a substantial input of ATP but at the same time are sensitive to free oxygen. To meet the requirements of this paradoxical situation,

4028-574: 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

4104-461: The main Cesalpinioideae clades have been estimated as between 56 and 34 million years and the basal group of the Mimosoideae as 44 ± 2.6 million years. The division between Mimosoideae and Faboideae is dated as occurring between 59 and 34 million years ago and the basal group of the Faboideae as 58.6 ± 0.2 million years ago. It has been possible to date the divergence of some of the groups within

4180-580: The more than 50 phyla of bacteria . Some of these lineages co-evolved together with the flowering plants establishing the molecular basis of a mutually beneficial symbiotic relationship. BNF is carried out in nodules that are mainly located in the root cortex, although they are occasionally located in the stem as in Sesbania rostrata . The spermatophytes that co-evolved with actinorhizal diazotrophs ( Frankia ) or with rhizobia to establish their symbiotic relationship belong to 11 families contained within

4256-437: 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"

4332-409: The pathways need for nodulation. The main donors to the pathway were the genes associated with the arbuscular mycorrhiza symbiosis genes, the pollen tube formation genes and the haemoglobin genes. One of the main genes shown to be shared between the arbuscular mycorrhiza pathway and the nodulation pathway is SYMRK and it is involved in the plant-bacterial recognition. The pollen tube growth is similar to

4408-431: The plant from herbivore insects (a form of mutualism ). Extrafloral nectaries are common among the Mimosoideae and the Caesalpinioideae, and are also found in some Faboideae (e.g. Vicia sativa ). In some Acacia , the modified hollow stipules are inhabited by ants and are known as domatia . Many Fabaceae host bacteria in their roots within structures called root nodules . These bacteria, known as rhizobia , have

These three genetic pathways are believed to be part of a gene duplication event then recruited to work in nodulation. The phylogeny of the legumes has been the object of many studies by research groups from around the world. These studies have used morphology, DNA data (the chloroplast intron trnL ,

4560-858: The process. Legumes are commonly used as natural fertilizers. Some legume species perform hydraulic lift , which makes them ideal for intercropping . Farmed legumes can belong to numerous classes, including forage , grain , blooms, pharmaceutical/industrial, fallow/green manure and timber species, with most commercially farmed species filling two or more roles simultaneously. There are of two broad types of forage legumes. Some, like alfalfa , clover , vetch , and Arachis , are sown in pasture and grazed by livestock. Other forage legumes such as Leucaena or Albizia are woody shrub or tree species that are either broken down by livestock or regularly cut by humans to provide fodder . Grain legumes are cultivated for their seeds , and are also called pulses . The seeds are used for human and animal consumption or for

Fallow or green manure legume species are cultivated to be tilled back into the soil to exploit the high nitrogen levels found in most legumes. Numerous legumes are farmed for this purpose, including Leucaena , Cyamopsis and Sesbania . Various legume species are farmed for timber production worldwide, including numerous Acacia species, Dalbergia species, and Castanospermum australe . Melliferous plants offer nectar to bees and other insects to encourage them to carry pollen from

Lathyrus tuberosus , once extensively cultivated in Europe, forms tubers used for human consumption. Bloom legume species include species such as lupin , which are farmed commercially for their blooms, and thus are popular in gardens worldwide. Laburnum , Robinia , Gleditsia (honey locust), Acacia , Mimosa , and Delonix are ornamental trees and shrubs . Industrial farmed legumes include Indigofera , cultivated for

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

4940-425: The showiest part of the flower. All of the flowers in an inflorescence open at once. In the Faboideae , the flowers are zygomorphic, and have a specialized structure . The upper petal, called the banner or standard, is large and envelops the rest of the petals in bud, often reflexing when the flower blooms. The two adjacent petals, the wings, surround the two bottom petals. The two bottom petals are fused together at

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

5244-654: The three sub-families indicates that nodule formation has arisen several times during the evolution of the Fabaceae and that this ability has been lost in some lineages. For example, within the genus Acacia , a member of the Mimosoideae, A. pentagona does not form nodules, while other species of the same genus readily form nodules, as is the case for Acacia senegal , which forms both rapidly and slow growing rhizobial nodules. A large number of species within many genera of leguminous plants, e.g. Astragalus , Coronilla , Hippocrepis , Indigofera , Lotus , Securigera and Scorpiurus , produce chemicals that derive from

5320-478: The traditional family Tiliaceae is polyphyletic . In the de Candolle system the circumscription of the family was: According to APG II system , the current placement of these genera is mostly in the Malvaceae sensu lato, but with Gyrostemon moved to family Gyrostemonaceae , Muntingia to family Muntingiaceae , Sloanea to family Elaeocarpaceae , Vatica to family Dipterocarpaceae and Wikstroemia to family Thymelaeaceae (possibly reduced to

5396-408: 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. It produces fragrant and nectar-producing flowers and is an important honey plant for beekeepers, giving rise to

5472-402: 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

5548-541: The wide variety of edible vegetables they represent and due to the variety of uses they can be put to: in horticulture and agriculture, as a food, for the compounds they contain that have medicinal uses and for the oil and fats they contain that have a variety of uses. The history of legumes is tied in closely with that of human civilization, appearing early in Asia , the Americas (the common bean , several varieties) and Europe (broad beans) by 6,000 BCE , where they became

5624-514: 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. 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 ),

5700-457: The world, including Cytisus scoparius (broom), Robinia pseudoacacia (black locust) , Ulex europaeus (gorse), Pueraria montana (kudzu), and a number of Lupinus species. The name 'Fabaceae' comes from the defunct genus Faba , now included in Vicia . The term "faba" comes from Latin, and appears to simply mean "bean". Leguminosae is an older name still considered valid, and refers to

5776-477: Was preferred for clothing there during the Bronze Age. The Manchu people in the mountains of Northeast China made ropes, baskets, raincoats, large fishing nets, and guide lines for gunpowder from the bast. 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
