78-553: Arundinaria is a genus of bamboo in the grass family the members of which are referred to generally as cane . Arundinaria is the only bamboo native to North America, with a native range from Maryland south to Florida and west to the southern Ohio Valley and Texas . Within this region Arundinaria canes are found from the Coastal Plain to medium elevations in the Appalachian Mountains . Prior to

156-493: A nomen oblitum , and the junior name declared a nomen protectum . This rule exists primarily to prevent the confusion that would result if a well-known name, with a large accompanying body of literature, were to be replaced by a completely unfamiliar name. An example is the European land snail Petasina edentula ( Draparnaud , 1805). In 2002, researchers found that an older name Helix depilata Draparnaud, 1801 referred to

234-557: 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 ,

312-486: A basket that is 100 years old can look the same as one that is 500 years old. Cane splits are dyed a variety of colors including black, brown, red, orange, yellow, or purple and woven into intricate geometric designs. Claude Medford Jr., a Choctaw craftsman, taught the techniques of boiling bloodroot with salt for orange dye, using black walnut for brown and black dye, soaking cane along with curly dock for yellow, and adding mussel shells to cane soaking in curly dock to change

390-487: A complex taxonomic history spanning over two centuries. The canes of the southeastern U.S. were originally described as two species of reed grasses in the genus Arundo by Thomas Walter in 1788. André Michaux , working in 1803 and unaware of Walter's work, correctly interpreted the canes as a distinct group and created the genus Arundinaria with one species. However, neither of these researchers left enough information to their successors, leading to confusion surrounding

468-437: A junior subjective synonym. Objective synonyms are common at the rank of genera, because for various reasons two genera may contain the same type species; these are objective synonyms. In many cases researchers established new generic names because they thought this was necessary or did not know that others had previously established another genus for the same group of species. An example is the genus Pomatia Beck, 1837, which

546-651: 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

624-428: A listing of "synonyms", a "synonymy", often contains designations that for some reason did not make it as a formal name, such as manuscript names, or even misidentifications (although it is now the usual practice to list misidentifications separately ). Although the basic principles are fairly similar, the treatment of synonyms in botanical nomenclature differs in detail and terminology from zoological nomenclature, where

702-628: 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,

780-444: A new monotypic genus for it: Arundinaria macrosperma Michx. . The name of the genus he used is derived from the same Latin word used by Walter for the plants he described; namely arundo , meaning " reed ". Despite the work done by Walter and Michaux, subsequent researchers had difficulty interpreting their circumscriptions of species boundaries. Walter designated no type specimens , and his Latin protologues that describe

858-409: 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

936-440: A species is moved to a different genus, a variety is moved to a different species, etc. Synonyms also come about when the codes of nomenclature change, so that older names are no longer acceptable; for example, Erica herbacea L. has been rejected in favour of Erica carnea L. and is thus its synonym. To the general user of scientific names, in fields such as agriculture, horticulture, ecology, general science, etc.,

1014-434: A species, or simple ignorance about an earlier description, may lead a biologist to describe a newly discovered specimen as a new species. A common reason for objective synonyms at this level is the creation of a replacement name. A junior synonym can be given precedence over a senior synonym, primarily when the senior name has not been used since 1899, and the junior name is in common use. The older name may be declared to be

1092-418: A synonym is a name that was previously used as the correct scientific name (in handbooks and similar sources) but which has been displaced by another scientific name, which is now regarded as correct. Thus Oxford Dictionaries Online defines the term as "a taxonomic name which has the same application as another, especially one which has been superseded and is no longer valid". In handbooks and general texts, it

1170-481: A taxon, some of this (including species descriptions, distribution, ecology and more) may well have been published under names now regarded as outdated (i.e., synonyms) and so it is again useful to know a list of historic synonyms which may have been used for a given current (valid) taxon name. Objective synonyms refer to taxa with the same type and same rank (more or less the same taxon, although circumscription may vary, even widely). This may be species-group taxa of

1248-427: 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. ;

1326-455: 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

1404-427: Is a synonym. In taxonomy, synonyms are not equals, but have a different status. For any taxon with a particular circumscription , position, and rank, only one scientific name is considered to be the correct one at any given time (this correct name is to be determined by applying the relevant code of nomenclature ). A synonym cannot exist in isolation: it is always an alternative to a different scientific name. Given that

1482-612: 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

1560-504: Is favored over all other materials for crafting. It can be split into coarser sections for sturdier baskets, or split very thinly for baskets that are delicate and flexible. The smooth, satiny outer surface of the cane stems forms a natural patina when heat or friction is applied to the outer surface. Cane suitable for basket weaving is straight, with the nodes spaced far apart. Cane is processed by splitting cut sections from top to bottom into quarters or eighths, and then carefully peeling off

1638-410: Is not correct for the circumscription , position, and rank of the taxon as considered in the particular botanical publication. It is always "a synonym of the correct scientific name", but which name is correct depends on the taxonomic opinion of the author. In botany the various kinds of synonyms are: In botany, although a synonym must be a formally accepted scientific name (a validly published name):

1716-460: 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,

1794-474: 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

1872-411: Is useful to have synonyms mentioned as such after the current scientific name, so as to avoid confusion. For example, if the much-advertised name change should go through and the scientific name of the fruit fly were changed to Sophophora melanogaster , it would be very helpful if any mention of this name was accompanied by "(syn. Drosophila melanogaster )". Synonyms used in this way may not always meet

1950-684: The Eastern Woodlands . The Atakapa , Catawba , Muscogee Creek , Chickasaw, Choctaw , Cherokee , and other Southeastern tribes have traditionally used this material for mat and basket weaving , and the Chitimacha and Eastern Band Cherokee still widely weave with rivercane today, though basket makers have started making smaller baskets in order to use less material and preserve the increasingly rare river cane. Bean poles made from dried canes can last for several years if properly stored when not in use. There are several reasons river cane

2028-523: The European colonization of the Americas , cane was an important resource for Indigenous peoples of the Americas . Early European explorers in the U.S. described vast monotypic stands of Arundinaria that were common in river lowlands and covered hundreds of thousands of hectares . In the modern era, Arundinaria canebrakes are small and isolated, but there has been interest in restoring them due to

2106-419: The International Code of Botanical Nomenclature in order to clarify older ambiguous types, were designated for Arundo gigantea Walt. and Arundinaria macrosperma Michx. . This allows current and future researchers to know precisely what is being discussed when the scientific names applied to these plants are used. Ethnobotanists consider cane to have been extremely important to Native Americans in

2184-621: 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

2262-824: 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;

2340-589: The Southeastern Woodlands before European colonisation . The river cane basketry art is at minimum 3000 years old, and can arguably be considered "the most difficult and complex of weaving technologies." The plant was used to make structures, arrow shafts, weapons, torches, fishing equipment, jewelry, baskets, musical instruments, furniture, boats, pipe stems, and medicines. Arundinaria gigantea , or river cane, has historically been used to construct Native American flutes , particularly among tribes of

2418-690: The United Keetoowah Band of Cherokee Indians was awarded a $ 1.9 million grant by the National Fish and Wildlife Foundation to manage and restore river cane ecosystems throughout their historic homelands in Oklahoma. 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

2496-404: 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,

2574-608: The American Arundinaria bamboos subsequently led to a variety of taxonomic treatments, with some authors arguing that only the North American species should be included, while others included dozens of Asian species otherwise considered members of other genera ( Bashania , Oligostachyum , Sarocalamus , Fargesia , Sasa , etc.). Even African bamboos were placed in Arundinaria under broad concepts for

2652-473: 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

2730-488: The authors have inspected the original material; a . that they take on the responsibility for the act of synonymizing the taxa. The accurate use of scientific names, including synonyms, is crucial in biomedical and pharmacological research involving plants. Failure to use correct botanical nomenclature can lead to ambiguity, hinder reproducibility of results, and potentially cause errors in medicine. Best practices for publication suggest that researchers should provide

2808-442: 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

2886-419: The beginning of § Zoology . The two are related, with only one word difference between their names.) For example, the scientific name of the red imported fire ant , Solenopsis invicta was published by Buren in 1972, who did not know that this species was first named Solenopsis saevissima wagneri by Santschi in 1916; as there were thousands of publications using the name invicta before anyone discovered

2964-414: The colony usually dies afterwards, possibly because the dense thickets of a mature canebrake would otherwise prevent seedling establishment. Only two flowering events are known for A. appalachiana. A colony of cane will expand rapidly using asexual reproduction following disturbances, particularly fire, which triggers new shoots to immediately sprout from the underground rhizomes after the above-ground part of

3042-411: The color to red. Plaiting and twilling are the two basic weaving techniques utilized in river cane baskets, and from there many variations exist, including double-woven baskets. Different tribes of Native Americans, and often specific families, had their own unique designs and techniques, which spread around through trade. The Chitimacha and Catawba split the cane into very narrow splits and weave them with

3120-567: The common cereals. Ergot-infected plants will have pink or purplish blotches or growths about the size of a seed or several times larger. Medicinally, the Choctaw use the roots for their painkilling properties. The organization Revitalization of Traditional Cherokee Artisan Resources, using funding from the Cherokee Preservation Foundation , has helped establish restoration sites for Arundinaria gigantea . In 2022,

3198-421: The correct name is included among synonyms, although as first among equals it is the "senior synonym": Scientific papers may include lists of taxa, synonymizing existing taxa and (in some cases) listing references to them. The status of a synonym may be indicated by symbols, as for instance in a system proposed for use in paleontology by Rudolf Richter. In that system a v before the year would indicate that

Arundinaria - Misplaced Pages Continue

3276-425: The correct name of a taxon depends on the taxonomic viewpoint used (resulting in a particular circumscription, position and rank) a name that is one taxonomist's synonym may be another taxonomist's correct name (and vice versa ). Synonyms may arise whenever the same taxon is described and named more than once, independently. They may also arise when existing taxa are changed, as when two taxa are joined to become one,

3354-619: The cultural and ecological importance of the plant. Canebrakes provided land for crops, habitat for wild game, and year-round forage for livestock. The cane itself was used for construction, weapons, jewelry, medicines, fuel, and food. Canebrakes declined significantly after colonization due to clearing, farming and fire suppression. Arundinaria species have running rhizomes and have slender, woody culms that reach heights from 0.5 to 8 metres (1.6 to 26.2 ft). Arundinaria produce seeds only rarely and usually reproduce vegetatively, forming large clonal genets . When seed production does occur,

3432-649: The currently accepted binomial with author citation, relevant synonyms, and the accepted family name according to the Angiosperm Phylogeny Group III classification. This practice ensures clear communication, allows proper linking of research to existing literature, and provides insight into phylogenetic relationships that may be relevant to shared chemical constituents or physiological effects. Online databases now make it easy for researchers to access correct nomenclature and synonymy information for plant species. The traditional concept of synonymy

3510-446: 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

3588-737: 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,

3666-541: The genus to two species. By the late 20th century, Floyd Alonzo McClure's 1973 survey of Arundinaria was also considered authoritative, and included only one species, Arundinaria gigantea . Most recently, in 2006 researchers from Iowa State University and the University of North Carolina recognised and described a third species, Arundinaria appalachiana Triplett, Weakley & L.G. Clark . The plants that form this species were previously thought to form part of

3744-575: The group. Some outdated systems during this era assigned Arundinaria more than 400 species. A. S. Hitchcock 's review of the taxonomic state of the North American bamboos was first published in 1935 as part of the Manual of the Grasses of the United States . He interpreted Michaux's Arundinaria macrosperma Michx. as a synonym of Walter's Arundinaria gigantea (Walt.) Muhl. , reducing

3822-432: 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

3900-493: The identity of the species they had described. A decade later in 1813, G.H.E. Muhlenberg noticed the affinities between the two previous authors' work and transferred Walter's two species to Michaux's new genus, yielding a combinatio nova for each, namely Arundinaria gigantea (Walt.) Muhl. and Arundinaria tecta (Walt.) Muhl. . Muhlenberg considered the genus to consist of these two species in addition to Arundinaria macrosperma Michx. . The phenotypic diversity of

3978-401: The junior synonym. (Incidentally, this species has since been reclassified and currently resides in the genus Bubo , as Bubo scandiacus ). One basic principle of zoological nomenclature is that the earliest correctly published (and thus available ) name, the senior synonym, by default takes precedence in naming rights and therefore, unless other restrictions interfere, must be used for

4056-633: 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,

4134-404: The lizard genus Anolis has been suggested to be broken down into 8 or so different genera which would bring its ~400 species to smaller, more manageable subsets. Synonym (taxonomy) The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. Unlike synonyms in other contexts, in taxonomy a synonym is not interchangeable with the name of which it

4212-403: 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

4290-428: 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

4368-415: The natural genetic diversity of Arundinaria gigantea (Walt.) Muhl. , but upon in depth analysis using modern phylogenetic methods based on morphology and amplified fragment length polymorphisms , the researchers determined that the canes form three species. Phylogenetic studies in 2006 using molecular and morphological evidence have suggested that the genus forms three natural species confined to

4446-438: The original Choctaw names for patterns used in basketry, which had to be planned using mathematics because they were so sophisticated. Many traditional patterns themselves, however, still survive. Food uses include flour, cereal, and even "asparagus" of young shoots; however, caution should be used whenever foraging for cane seeds, as the extremely toxic fungus ergot ( Claviceps spp.) can colonize its seeds as well as those of

4524-484: The plant has burned. These shoots grow quickly, up to 1.5 inches per day. Among the distinctive features of the canes is a fan-like cluster of leaves at the top of new stems called a topknot, so-called because of its resemblance to topknot hairstyles . There are four species of Arundinaria accepted by the World Checklist of Vascular Plants (WCVP) as of January 2024, listed below. The genus Arundinaria has

4602-541: 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

4680-469: The rules of nomenclature; as for example when an older name is (re)discovered which has priority over the current name. Speaking in general, name changes for nomenclatural reasons have become less frequent over time as the rules of nomenclature allow for names to be conserved, so as to promote stability of scientific names. In zoological nomenclature, codified in the International Code of Zoological Nomenclature , synonyms are different scientific names of

4758-408: The same taxonomic rank that pertain to that same taxon . For example, a particular species could, over time, have had two or more species-rank names published for it, while the same is applicable at higher ranks such as genera, families, orders, etc. In each case, the earliest published name is called the senior synonym , while the later name is the junior synonym . In the case where two names for

SECTION 60

4836-409: The same rank with the same type specimen , genus-group taxa of the same rank with the same type species or if their type species are themselves objective synonyms, of family-group taxa with the same type genus, etc. In the case of subjective synonyms , there is no such shared type, so the synonymy is open to taxonomic judgement, meaning that there is room for debate: one researcher might consider

4914-534: The same species, but this name had never been used after 1899 and was fixed as a nomen oblitum under this rule by Falkner et al. 2002. Such a reversal of precedence is also possible if the senior synonym was established after 1900, but only if the International Commission on Zoological Nomenclature (ICZN) approves an application. (Here the C in ICZN stands for Commission, not Code as it does at

4992-407: The same taxon have been published simultaneously, the valid name is selected accorded to the principle of the first reviser such that, for example, of the names Strix scandiaca and Strix noctua (Aves), both published by Linnaeus in the same work at the same date for the taxon now determined to be the snowy owl , the epithet scandiaca has been selected as the valid name, with noctua becoming

5070-400: The smooth outer layer in a single long piece, scraping off any excess material from the inner surface until the splits are thin and flexible enough to be easily wrapped around the artisan's finger. The splits are soaked in water to keep them flexible and woven wet. Undyed cane baskets change from green, to cream, to finally yellow as they age. After this, the color of the cane does not change and

5148-399: The smooth side inward, whereas the Choctaw weave with wider splits and face the smooth side outward. When Native Americans were forced into lands different than their homelands, many techniques became lost, and new techniques had to be found for dyeing and crafting. Other new techniques were adopted to be marketable to European settlers for trading. One example of knowledge that has been lost is

5226-473: The southeastern United States. Two of the three species currently placed in the genus, Arundinaria gigantea and Arundinaria tecta , were first described scientifically by Thomas Walter in his 1788 Flora Caroliniana . Walter placed them in the grass genus Arundo . In 1803, the French botanist André Michaux , unaware of the flora prepared by Walter, also published a description of the canes he encountered. Michaux recognised only one species, but created

5304-411: The species are vague, including features that could be any of the three species currently recognized. Michaux did designate a type specimen for the species he described, but it does not include enough of the plant to determine with confidence which species it represents, while his protologues were likewise not detailed enough to avoid ambiguity. In 2009, epitypes , a new form of botanical type allowed by

5382-497: 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,

5460-412: 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

5538-493: The strict definitions of the term "synonym" in the formal rules of nomenclature which govern scientific names (see below) . Changes of scientific name have two causes: they may be taxonomic or nomenclatural. A name change may be caused by changes in the circumscription, position or rank of a taxon, representing a change in taxonomic, scientific insight (as would be the case for the fruit fly, mentioned above). A name change may be due to purely nomenclatural reasons, that is, based on

5616-401: The synonymy, the ICZN, in 2001, ruled that invicta would be given precedence over wagneri . To qualify as a synonym in zoology, a name must be properly published in accordance with the rules. Manuscript names and names that were mentioned without any description ( nomina nuda ) are not considered as synonyms in zoological nomenclature. In botanical nomenclature , a synonym is a name that

5694-403: 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

5772-406: The taxon. However, junior synonyms are still important to document, because if the earliest name cannot be used (for example, because the same spelling had previously been used for a name established for another taxon), then the next available junior synonym must be used for the taxon. For other purposes, if a researcher is interested in consulting or compiling all currently known information regarding

5850-479: The two (or more) types to refer to one and the same taxon, another might consider them to belong to different taxa. For example, John Edward Gray published the name Antilocapra anteflexa in 1855 for a species of pronghorn , based on a pair of horns. However, it is now commonly accepted that his specimen was an unusual individual of the species Antilocapra americana published by George Ord in 1815. Ord's name thus takes precedence, with Antilocapra anteflexa being

5928-576: 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

6006-429: 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 . As with scientific names at other ranks, in all groups other than viruses, names of genera may be cited with their authorities, typically in

6084-545: Was established for a group of terrestrial snails containing as its type species the Burgundy or Roman snail Helix pomatia —since Helix pomatia was already the type species for the genus Helix Linnaeus, 1758, the genus Pomatia was an objective synonym (and useless). On the same occasion, Helix is also a synonym of Pomatia , but it is older and so it has precedence. At the species level, subjective synonyms are common because of an unexpectedly large range of variation in
