The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently.
34-456: Chondrillinae Cichoriinae Crepidinae Hieraciinae Hyoseridinae Hypochaeridinae Lactucinae Microseridinae Scolyminae Scorzonerinae Warioniinae Lactuceae Cassini The Cichorieae (also called Lactuceae ) are a tribe in the plant family Asteraceae that includes 93 genera, more than 1,600 sexually reproductive species and more than 7,000 apomictic species. They are found primarily in temperate regions of
68-493: 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
102-573: A taxonomic unit , calling it the "13th class of the plant kingdom". He only assigned taxa to it that are still regarded part of the Cichorieae today. Sébastien Vaillant gave this group the name "Cichoracées" in 1723. Since the name predates the start of the Linnean nomenclature in 1753, it is not valid , but Jean-Baptiste Lamarck and Augustin Pyramus de Candolle used the name Cichorieae in
136-418: 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.,
170-405: 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 the correct name of a taxon depends on
204-437: 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
238-428: 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
272-434: 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
306-501: A strap-shaped corolla with five teeth at its tip), a rare character that is further present only in the genera Catamixis , Glossarion , Hyaloseris ( Mutisieae ), and Fitchia ( Heliantheae ). However, recently the genera Gundelia and Warionia have been included in the Cichorieae, and those two genera have heads containing only disk flowers. In his Elemens de botanique ou methode pour connoître les plantes of 1694, Joseph Pitton de Tournefort first described this group as
340-418: 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
374-481: 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

#1732780805611408-410: 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):
442-411: 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
476-765: The Synopsis Plantarium in Flora Gallica Descriptarum , published in 1806. The name Lactuceae that was cioned by Henri Cassini in 1819, comprises the same group of taxa and is thus a synonym . Obviously, over the centuries since the group was first identified, numerous new taxa have been described that are now included in the Cichorieae, and the group has been divided in different subgroups using various morphological character states by authors such as Cassini, David Don , Christian Friedrich Lessing , A.P. De Candolle, George Bentham and Karl August Otto Hoffmann . Genetic analysis has increased
510-833: The Eastern Hemisphere. Cichorieae all have milky latex and flowerheads that only contain one type of floret . The genera Gundelia and Warionia only have disk florets , while all other genera only have ligulate florets . The genera that contain most species are Taraxacum (Crepidinae subtribe) with about 1,600 apomictic species, Hieracium with about 770 sexually reproducing and 5,200 apomictic species, and Pilosella with 110 sexually reproducing and 700 apomictic species (both Hieraciinae). Well-known members include lettuce , chicory , dandelion , and salsify . Most species are herbaceous , perennial , short-lived or annual plants , rarely subshrubs , shrubs or vines . All Cichorieae-species have latex canals in both

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
646-421: 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

#1732780805611748-401: 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
782-542: The roots, stems and leaves, and this occurs to be a unique character among the Asteraceae, although latex as such occurs rather widespread in this family. The leaves are in a rosette or alternately set along the stem, but this is the dominant situation in the Asteraceae. The only exception in the Cichorieae are the opposite lower leaves of Shinnersoseris . Traditionally, the Cichorieae consisted of taxa with flowerheads only containing bisexual ligulate florets (having
816-536: 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
850-408: 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
884-409: 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
918-534: 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.

986-493: 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
1020-401: 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
1054-406: 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

1088-408: 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, a species is moved to
1122-479: 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

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
