71-416: See Ficus § Subgenus Urostigma . A banyan , also spelled banian ( / ˈ b æ n j ən / BAN -yən ), is a fig that develops accessory trunks from adjacent prop roots , allowing the tree to spread outwards indefinitely. This distinguishes banyans from other trees with a strangler habit that begin life as an epiphyte , i.e. a plant that grows on another plant, when its seed germinates in

142-557: A species : see Botanical name and Specific name (zoology) . The rules for the scientific names of organisms are laid down in the nomenclature codes , which allow each species a single unique name that, for animals (including protists ), plants (also including algae and fungi ) and prokaryotes ( bacteria and archaea ), is Latin and binomial in form; this contrasts with common or vernacular names , which are non-standardized, can be non-unique, and typically also vary by country and language of usage. Except for viruses ,

213-419: A syconium , derived from an arrangement of many small flowers on an inverted, nearly closed receptacle. The many small flowers are unseen unless the fig is cut open. The fruit typically has a bulbous shape with a small opening (the ostiole ) at the outward end that allows access to pollinators . The flowers are pollinated by very small wasps such as Pegoscapus that crawl through the opening in search of

284-404: A constant source of inspiration and wonder to biologists. Notably, three vegetative traits together are unique to figs. All figs present a white to yellowish latex , some in copious quantities; the twig shows paired stipules —or circular scars if the stipules have fallen off; the lateral veins at the base of the leaf are steep, forming a tighter angle with the midrib than the other lateral veins,

355-402: A crack or crevice of a host tree or edifice. "Banyan" often specifically denotes Ficus benghalensis (the "Indian banyan"), which is the national tree of India, though the name has also been generalized to denominate all figs that share a common life cycle and used systematically in taxonomy to denominate the subgenus Urostigma . Like other fig species, banyans bear their fruit in

426-597: A distinctive shape or habit, and their fruits distinguish them from other plants. The fruit of Ficus is an inflorescence enclosed in an urn-like structure called a syconium , which is lined on the inside with the fig's tiny flowers that develop into multiple ovaries on the inside surface. In essence, the fig fruit is a fleshy stem with multiple tiny flowers that fruit and coalesce. The unique fig pollination system, involving tiny, highly specific wasps, known as fig wasps that enter via ostiole these subclosed inflorescences to both pollinate and lay their own eggs, has been

497-418: A feature referred to as "triveined". Current molecular clock estimates indicate that Ficus is a relatively ancient genus, being at least 60 million years old, and possibly as old as 80 million years. The main radiation of extant species, however, may have taken place more recently, between 20 and 40 million years ago. Some better-known species that represent the diversity of the genus include, alongside

568-515: A fibrous cloth used for clothing. Figs have figured prominently in some human cultures. There is evidence that figs, specifically the common fig ( F. carica ) and sycamore fig ( Ficus sycomorus ), were among the first – if not the very first – plant species that were deliberately bred for agriculture in the Middle East, starting more than 11,000 years ago. Nine subfossil F. carica figs dated to about 9400–9200 BCE were found in

639-689: A fresh fig, individual fruit will appear as fleshy "threads", each bearing a single seed inside. The genus Dorstenia , also in the fig family (Moraceae), exhibits similar tiny flowers arranged on a receptacle but in this case the receptacle is a more or less flat, open surface. Fig plants can be monoecious ( hermaphrodite ) or gynodioecious (hermaphrodite and female). Nearly half of fig species are gynodioecious, and therefore have some plants with inflorescences (syconium) with long styled pistillate flowers, and other plants with staminate flowers mixed with short styled pistillate flowers. The long-styled flowers tend to prevent wasps from laying their eggs within

710-443: A key resource for some frugivores including fruit bats , and primates including: capuchin monkeys , langurs , gibbons and mangabeys . They are even more important for birds such as Asian barbets , pigeons , hornbills , fig-parrots and bulbuls , which may almost entirely subsist on figs when these are in plenty. Many Lepidoptera caterpillars feed on fig leaves, for example several Euploea species (crow butterflies),

781-651: A later homonym of a validly published name is a nomen illegitimum or nom. illeg. ; for a full list refer to the International Code of Nomenclature for algae, fungi, and plants and the work cited above by Hawksworth, 2010. In place of the "valid taxon" in zoology, the nearest equivalent in botany is " correct name " or "current name" which can, again, differ or change with alternative taxonomic treatments or new information that results in previously accepted genera being combined or split. Prokaryote and virus codes of nomenclature also exist which serve as

852-628: A long time and redescribed as new by a range of subsequent workers, or if a range of genera previously considered separate taxa have subsequently been consolidated into one. For example, the World Register of Marine Species presently lists 8 genus-level synonyms for the sperm whale genus Physeter Linnaeus, 1758, and 13 for the bivalve genus Pecten O.F. Müller, 1776. Within the same kingdom, one generic name can apply to one genus only. However, many names have been assigned (usually unintentionally) to two or more different genera. For example,

923-409: A reference for designating currently accepted genus names as opposed to others which may be either reduced to synonymy, or, in the case of prokaryotes, relegated to a status of "names without standing in prokaryotic nomenclature". An available (zoological) or validly published (botanical) name that has been historically applied to a genus but is not regarded as the accepted (current/valid) name for

994-574: A subject specimen in penjing and bonsai . The oldest living bonsai in Taiwan is a 240-year-old banyan tree housed in Tainan . Banyan trees figure prominently in several Asian and Pacific religions and myths, including: Ficus#Subgenus Urostigma About 800, see text Ficus ( / ˈ f aɪ k ə s / or / ˈ f iː k ə s / ) is a genus of about 850 species of woody trees , shrubs , vines , epiphytes and hemiepiphytes in

1065-448: A suitable place to lay eggs. Without this pollinator service fig trees could not reproduce by seed. In turn, the flowers provide a safe haven and nourishment for the next generation of wasps. This accounts for the frequent presence of wasp larvae in the fruit, and has led to a coevolutionary relationship. Technically, a fig fruit proper would be only one of the many tiny matured, seed-bearing gynoecia found inside one fig – if you cut open

1136-427: A taxon; however, the names published in suppressed works are made unavailable via the relevant Opinion dealing with the work in question. In botany, similar concepts exist but with different labels. The botanical equivalent of zoology's "available name" is a validly published name . An invalidly published name is a nomen invalidum or nom. inval. ; a rejected name is a nomen rejiciendum or nom. rej. ;

1207-455: A total of c. 520,000 published names (including synonyms) as at end 2019, increasing at some 2,500 published generic names per year. "Official" registers of taxon names at all ranks, including genera, exist for a few groups only such as viruses and prokaryotes, while for others there are compendia with no "official" standing such as Index Fungorum for fungi, Index Nominum Algarum and AlgaeBase for algae, Index Nominum Genericorum and

1278-529: A wide area. In some species, the prop roots develop over a considerable area that resembles a grove of trees, with every trunk connected directly or indirectly to the primary trunk. The topology of this massive root system inspired the name of the hierarchical computer network operating system " Banyan VINES ". In a banyan that envelops its host tree, the mesh of roots growing around the latter eventually applies considerable pressure to and commonly kills it. Such an enveloped, dead tree eventually decomposes, so that

1349-528: Is a sura in Quran named "The Fig" or At-Tin (سوره تین). In Asia, figs are important in Buddhism and Hinduism . In Jainism , the consumption of any fruit belonging to this genus is prohibited. The Buddha is traditionally held to have found bodhi (enlightenment) while meditating for 49 days under a sacred fig . The same species was Ashvattha , the " world tree " of Hinduism. The Plaksa Pra-sravana

1420-494: Is a gynodioecious plant, as well as lofty fig or clown fig ( F. aspera ), Roxburgh fig ( F. auriculata ), mistletoe fig ( F. deltoidea ), F. pseudopalma , creeping fig ( F. pumila ) and related species. The hermaphrodite common figs are called "inedible figs" or "caprifigs"; in traditional culture in the Mediterranean region they were considered food for goats ( Capra aegagrus ). In

1491-697: Is also one of the traditional crops of Israel , and is included in the list of food found in the Promised Land, according to the Torah ( Deut. 8). Jesus cursed a fig tree for bearing no fruit. The fig tree was sacred in ancient Greece and Cyprus , where it was a symbol of fertility . Video Genus The composition of a genus is determined by taxonomists . The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including

1562-425: Is an example of mutualism , in which each organism (fig plant and fig wasp ) benefit each other, in this case reproductively. The intimate association between fig species and their wasp pollinators, along with the high incidence of a one-to-one plant-pollinator ratio have long led scientists to believe that figs and wasps are a clear example of coevolution . Morphological and reproductive behavior evidence, such as

1633-569: Is by far the largest genus in the Moraceae, and is one of the largest genera of flowering plants currently described. The species currently classified within Ficus were originally split into several genera in the mid-1800s, providing the basis for a subgeneric classification when reunited into one genus in 1867. This classification put functionally dioecious species into four subgenera based on floral characters. In 1965, E. J. H. Corner reorganized

1704-612: Is discouraged by both the International Code of Zoological Nomenclature and the International Code of Nomenclature for algae, fungi, and plants , there are some five thousand such names in use in more than one kingdom. For instance, A list of generic homonyms (with their authorities), including both available (validly published) and selected unavailable names, has been compiled by the Interim Register of Marine and Nonmarine Genera (IRMNG). The type genus forms

1775-411: Is frequently found as a pest on figs grown as potted plants and is spread through the export of these plants to other localities. For a list of other diseases common to fig trees, see List of foliage plant diseases (Moraceae) . Many fig species are grown for their fruits, though only Ficus carica is cultivated to any extent for this purpose. A fig "fruit" is a type of multiple fruit known as

1846-643: Is higher because not all wasp species were detected. On the other hand, species of wasps pollinate multiple host fig species. Molecular techniques, like microsatellite markers and mitochondrial sequence analysis, allowed a discovery of multiple genetically distinct, cryptic wasp species. Not all these cryptic species are sister taxa and thus must have experienced a host fig shift at some point. These cryptic species lacked evidence of genetic introgression or backcrosses indicating limited fitness for hybrids and effective reproductive isolation and speciation . The existence of cryptic species suggests that neither

1917-460: Is somewhat arbitrary. Although all species within a genus are supposed to be "similar", there are no objective criteria for grouping species into genera. There is much debate among zoologists about whether enormous, species-rich genera should be maintained, as it is extremely difficult to come up with identification keys or even character sets that distinguish all species. Hence, many taxonomists argue in favor of breaking down large genera. For instance,

1988-474: Is the type species , and the generic name is permanently associated with the type specimen of its type species. Should the specimen turn out to be assignable to another genus, the generic name linked to it becomes a junior synonym and the remaining taxa in the former genus need to be reassessed. In zoological usage, taxonomic names, including those of genera, are classified as "available" or "unavailable". Available names are those published in accordance with

2059-663: Is used to produce barkcloth in Uganda. Pou ( F. religiosa ) leaves' shape inspired one of the standard kbach rachana , decorative elements in Cambodian architecture. Indian banyan ( F. benghalensis ) and the Indian rubber plant, as well as other species, have use in herbalism . The inner bark of an unknown type of wild fig, locally known as urú , was once used by the Moré people  [ es ] of Bolivia to produce

2130-621: The International Code of Zoological Nomenclature ; the earliest such name for any taxon (for example, a genus) should then be selected as the " valid " (i.e., current or accepted) name for the taxon in question. Consequently, there will be more available names than valid names at any point in time; which names are currently in use depending on the judgement of taxonomists in either combining taxa described under multiple names, or splitting taxa which may bring available names previously treated as synonyms back into use. "Unavailable" names in zoology comprise names that either were not published according to

2201-824: The International Plant Names Index for plants in general, and ferns through angiosperms, respectively, and Nomenclator Zoologicus and the Index to Organism Names for zoological names. Totals for both "all names" and estimates for "accepted names" as held in the Interim Register of Marine and Nonmarine Genera (IRMNG) are broken down further in the publication by Rees et al., 2020 cited above. The accepted names estimates are as follows, broken down by kingdom: The cited ranges of uncertainty arise because IRMNG lists "uncertain" names (not researched therein) in addition to known "accepted" names;

2272-579: The common fig , whose fingered fig leaf is well known in art and iconography : the weeping fig ( F. benjamina ), a hemiepiphyte with thin, tough leaves on pendulous stalks adapted to its rain forest habitat; the rough-leaved sandpaper figs from Australia; and the creeping fig ( F. pumila ), a vine whose small, hard leaves form a dense carpet of foliage over rocks or garden walls. Moreover, figs with different plant habits have undergone adaptive radiation in different biogeographic regions, leading to very high levels of alpha diversity . In

2343-677: The family Moraceae . Collectively known as fig trees or figs , they are native throughout the tropics with a few species extending into the semi-warm temperate zone. The common fig ( F. carica ) is a temperate species native to southwest Asia and the Mediterranean region (from Afghanistan to Portugal), which has been widely cultivated from ancient times for its fruit , also referred to as figs. The fruit of most other species are also edible though they are usually of only local economic importance or eaten as bushfood . However, they are extremely important food resources for wildlife. Figs are also of considerable cultural importance throughout

2414-441: The plain tiger ( Danaus chrysippus ), the giant swallowtail ( Papilio cresphontes ), the brown awl ( Badamia exclamationis ), and Chrysodeixis eriosoma , Choreutidae and Copromorphidae moths . The citrus long-horned beetle ( Anoplophora chinensis ), for example, has larvae that feed on wood , including that of fig trees; it can become a pest in fig plantations. Similarly, the sweet potato whitefly ( Bemisia tabaci )

2485-404: The platypus belongs to the genus Ornithorhynchus although George Shaw named it Platypus in 1799 (these two names are thus synonyms ) . However, the name Platypus had already been given to a group of ambrosia beetles by Johann Friedrich Wilhelm Herbst in 1793. A name that means two different things is a homonym . Since beetles and platypuses are both members of the kingdom Animalia,

2556-473: The French botanist Joseph Pitton de Tournefort (1656–1708) is considered "the founder of the modern concept of genera". The scientific name (or the scientific epithet) of a genus is also called the generic name ; in modern style guides and science, it is always capitalised. It plays a fundamental role in binomial nomenclature , the system of naming organisms , where it is combined with the scientific name of

2627-403: The banyan becomes a "columnar tree" with a hollow, central core. In jungles, such hollows are very desirable shelters to many animals. From research, it is known that the longevity of banyan tree is due to multiple signs of adaptive (MSA) evolution of genes. The name was originally given to F. benghalensis and comes from India, where early European travelers observed that the shade of the tree

2698-442: The base for higher taxonomic ranks, such as the family name Canidae ("Canids") based on Canis . However, this does not typically ascend more than one or two levels: the order to which dogs and wolves belong is Carnivora ("Carnivores"). The numbers of either accepted, or all published genus names is not known precisely; Rees et al., 2020 estimate that approximately 310,000 accepted names (valid taxa) may exist, out of

2769-481: The breba crop is often destroyed by spring frosts. Some parthenocarpic cultivars of common figs do not require pollination at all, and will produce a crop of figs (albeit sterile ) in the absence of caprifigs and fig wasps. Depending on the species, each fruit can contain hundreds or even thousand of seeds. Figs can be propagated by seeds, cuttings, air-layering or grafting. However, as with any plant, figs grown from seed are not necessarily genetically identical to

2840-439: The correspondence between fig and wasp larvae maturation rates, have been cited as support for this hypothesis for many years. Additionally, recent genetic and molecular dating analyses have shown a very close correspondence in the character evolution and speciation phylogenies of these two clades. According to meta-analysis of molecular data for 119 fig species 35% (41) have multiple pollinator wasp species. The real proportion

2911-547: The early Neolithic village Gilgal I (in the Jordan Valley , 13 km, or 8.1 mi, north of Jericho ). These were a parthenogenetic type and thus apparently an early cultivar. This find predates the first known cultivation of grain in the Middle East by many hundreds of years. Numerous species of fig are found in cultivation in domestic and office environments, including: Fig trees have profoundly influenced culture through several religious traditions. Among

2982-411: The family Agaonidae for pollination. Adult plants vary in size from Ficus benghalensis which may cover a hectare (2.5 acres) or more of ground to Ficus nana of New Guinea which never exceeds one meter (forty inches) in height and width. Specific identification of many of the species can be difficult, but members of the genus Ficus are relatively easy to recognize. Many have aerial roots and

3053-420: The female fig trees, the male flower parts fail to develop; they produce the "'edible figs". Fig wasps grow in common fig caprifigs but not in the female syconiums because the female flower is too long for the wasp to successfully lay her eggs in them. Nonetheless, the wasp pollinates the flower with pollen from the caprifig it grew up in. In many situations, the wasp pollinator is unable to escape and dies within

3124-446: The form "author, year" in zoology, and "standard abbreviated author name" in botany. Thus in the examples above, the genus Canis would be cited in full as " Canis Linnaeus, 1758" (zoological usage), while Hibiscus , also first established by Linnaeus but in 1753, is simply " Hibiscus L." (botanical usage). Each genus should have a designated type , although in practice there is a backlog of older names without one. In zoology, this

3195-496: The form of a structure called a " syconium ". The syconium of Ficus species supply shelter and food for fig wasps and the trees depend on the fig wasps for pollination. Frugivore birds disperse the seeds of banyans. The seeds are small, and because most banyans grow in woodlands , a seedling that germinates on the ground is unlikely to survive. However, many seeds fall on the branches and stems of other trees or on human edifices, and when they germinate they grow roots down toward

3266-457: The fruit. When the wasp dies, it is broken down by enzymes ( Ficain ) inside the fig. Fig wasps are not known to transmit any diseases harmful to humans. When a caprifig ripens, another caprifig must be ready to be pollinated. In temperate climes, wasps hibernate in figs, and there are distinct crops. Caprifigs have three crops per year; common figs have two. The first crop ( breba ) is larger and juicier, and usually eaten fresh. In cold climates

3337-737: The generic name (or its abbreviated form) still forms the leading portion of the scientific name, for example, Canis lupus lupus for the Eurasian wolf subspecies, or as a botanical example, Hibiscus arnottianus ssp. immaculatus . Also, as visible in the above examples, the Latinised portions of the scientific names of genera and their included species (and infraspecies, where applicable) are, by convention, written in italics . The scientific names of virus species are descriptive, not binomial in form, and may or may not incorporate an indication of their containing genus; for example,

3408-421: The genus on the basis of breeding system, uniting these four dioecious subgenera into a single dioecious subgenus Ficus . Monoecious figs were classified within the subgenera Urostigma , Pharmacosycea and Sycomorus . This traditional classification has been called into question by recent phylogenetic studies employing genetic methods to investigate the relationships between representative members of

3479-423: The ground and consequently may envelop part of the host tree or edifice. This is colloquially known as a " strangler " habit, which banyans share with a number of other tropical Ficus species, as well as some other unrelated genera such as Clusia and Metrosideros . The leaves of the banyan tree are large, leathery, glossy, green, and elliptical. Like most figs, the leaf bud is covered by two large scales. As

3550-432: The idea that a newly defined genus should fulfill these three criteria to be descriptively useful: Moreover, genera should be composed of phylogenetic units of the same kind as other (analogous) genera. The term "genus" comes from Latin genus , a noun form cognate with gignere ('to bear; to give birth to'). The Swedish taxonomist Carl Linnaeus popularized its use in his 1753 Species Plantarum , but

3621-633: The largest component, with 23,236 ± 5,379 accepted genus names, of which 20,845 ± 4,494 are angiosperms (superclass Angiospermae). By comparison, the 2018 annual edition of the Catalogue of Life (estimated >90% complete, for extant species in the main) contains currently 175,363 "accepted" genus names for 1,744,204 living and 59,284 extinct species, also including genus names only (no species) for some groups. The number of species in genera varies considerably among taxonomic groups. For instance, among (non-avian) reptiles , which have about 1180 genera,

3692-553: The leaf develops the scales abscise. Young leaves have an attractive reddish tinge. Older banyan trees are characterized by aerial prop roots that mature into thick, woody trunks, which can become indistinguishable from the primary trunk with age. These aerial roots can become very numerous. The Great Banyan of Kolkata, which has been tracked carefully for many years, currently has 2,880 supplementary trunks. Such prop roots can be sixty feet (eighteen meters) in height. Old trees can spread laterally by using these prop roots to grow over

3763-513: The more famous species are the sacred fig tree (Pipal, bodhi, bo, or po, Ficus religiosa ) and other banyan figs such as Ficus benghalensis . The oldest living plant of known planting date is a Ficus religiosa tree known as the Sri Maha Bodhi planted in the temple at Anuradhapura , Sri Lanka by King Tissa in 288 BCE. The common fig is one of two significant trees in Islam , and there

3834-403: The most (>300) have only 1 species, ~360 have between 2 and 4 species, 260 have 5–10 species, ~200 have 11–50 species, and only 27 genera have more than 50 species. However, some insect genera such as the bee genera Lasioglossum and Andrena have over 1000 species each. The largest flowering plant genus, Astragalus , contains over 3,000 species. Which species are assigned to a genus

3905-428: The name could not be used for both. Johann Friedrich Blumenbach published the replacement name Ornithorhynchus in 1800. However, a genus in one kingdom is allowed to bear a scientific name that is in use as a generic name (or the name of a taxon in another rank) in a kingdom that is governed by a different nomenclature code. Names with the same form but applying to different taxa are called "homonyms". Although this

3976-400: The number of symbionts nor their evolutionary relationships are necessarily fixed ecologically. While the morphological characteristics that facilitate the fig-wasp mutualisms are likely to be shared more fully in closer relatives, the absence of unique pairings would make it impossible to do a one-to-one tree comparison and difficult to determine cospeciation. With over 800 species, Ficus

4047-464: The other section of Pharmacosycea , the rest of the monoecious species, and all of the dioecious species. These remaining species are divided into two main monophyletic lineages (though the statistical support for these lineages is not as strong as for the monophyly of the more derived clades within them). One consists of all sections of Urostigma except for section Urostigma s. s. . The other includes section Urostigma s. s. , subgenus Sycomorus , and

4118-584: The ovules, while the short-styled flowers are accessible for egg laying. All the native fig trees of the American continent are hermaphrodites, as well as species like Indian banyan ( F. benghalensis ), weeping fig ( F. benjamina ), Indian rubber plant ( F. elastica ), fiddle-leaved fig ( F. lyrata ), Moreton Bay fig ( F. macrophylla ), Chinese banyan ( F. microcarpa ), sacred fig ( F. religiosa ) and sycamore fig ( F. sycomorus ). The common fig ( Ficus carica )

4189-526: The parent and are only propagated this way for breeding purposes. Each species of fig is pollinated by one or a few specialised wasp species, and therefore plantings of fig species outside of their native range results in effectively sterile individuals. For example, in Hawaii , some 60 species of figs have been introduced, but only four of the wasps that fertilize them, so only those species of figs produce viable seeds there and can become invasive species . This

4260-541: The provisions of the ICZN Code, e.g., incorrect original or subsequent spellings, names published only in a thesis, and generic names published after 1930 with no type species indicated. According to "Glossary" section of the zoological Code, suppressed names (per published "Opinions" of the International Commission of Zoological Nomenclature) remain available but cannot be used as the valid name for

4331-858: The species of subgenus Ficus , though the relationships of the sections of these groups to one another are not well resolved. As of April 2024, there are 880 accepted Ficus species according to Plants of the World Online . The following species are typically spreading or climbing lianas : The wood of fig trees is often soft and the latex precludes its use for many purposes. It was used to make mummy caskets in Ancient Egypt . Certain fig species (mainly F. cotinifolia , F. insipida and F. padifolia ) are traditionally used in Mesoamerica to produce papel amate ( Nahuatl : āmatl ). Mutuba ( F. natalensis )

4402-497: The specific name particular to the wolf. A botanical example would be Hibiscus arnottianus , a particular species of the genus Hibiscus native to Hawaii. The specific name is written in lower-case and may be followed by subspecies names in zoology or a variety of infraspecific names in botany . When the generic name is already known from context, it may be shortened to its initial letter, for example, C. lupus in place of Canis lupus . Where species are further subdivided,

4473-412: The standard format for a species name comprises the generic name, indicating the genus to which the species belongs, followed by the specific epithet, which (within that genus) is unique to the species. For example, the gray wolf 's scientific name is Canis lupus , with Canis ( Latin for 'dog') being the generic name shared by the wolf's close relatives and lupus (Latin for 'wolf') being

4544-403: The taxon is termed a synonym ; some authors also include unavailable names in lists of synonyms as well as available names, such as misspellings, names previously published without fulfilling all of the requirements of the relevant nomenclatural code, and rejected or suppressed names. A particular genus name may have zero to many synonyms, the latter case generally if the genus has been known for

4615-502: The tropics, Ficus commonly is the most species-rich plant genus in a particular forest. In Asia, as many as 70 or more species can co-exist. Ficus species richness declines with an increase in latitude in both hemispheres. A description of fig tree cultivation is set out in Ibn al-'Awwam 's 12th-century agricultural work titled, Book on Agriculture . Figs are keystone species in many tropical forest ecosystems . Their fruit are

Ficus is a pantropical genus of trees, shrubs, and vines occupying a wide variety of ecological niches ; most are evergreen , but some deciduous species are found in areas outside of the tropics and to higher elevations. Fig species are characterized by their unique inflorescence and distinctive pollination syndrome , which uses wasp species belonging to

4757-576: The values quoted are the mean of "accepted" names alone (all "uncertain" names treated as unaccepted) and "accepted + uncertain" names (all "uncertain" names treated as accepted), with the associated range of uncertainty indicating these two extremes. Within Animalia, the largest phylum is Arthropoda , with 151,697 ± 33,160 accepted genus names, of which 114,387 ± 27,654 are insects (class Insecta). Within Plantae, Tracheophyta (vascular plants) make up

4828-407: The various sections of each subgenus. Of Corner's original subgeneric divisions of the genus, only Sycomorus is supported as monophyletic in the majority of phylogenetic studies. Notably, there is no clear split between dioecious and monoecious lineages. One of the two sections of Pharmacosycea , a monoecious group, form a monophyletic clade basal to the rest of the genus, which includes

4899-429: The virus species " Salmonid herpesvirus 1 ", " Salmonid herpesvirus 2 " and " Salmonid herpesvirus 3 " are all within the genus Salmonivirus ; however, the genus to which the species with the formal names " Everglades virus " and " Ross River virus " are assigned is Alphavirus .
