Genus ( / ˈ dʒ iː n ə s / ; pl. : genera / ˈ dʒ ɛ n ər ə / ) is a taxonomic rank above species and below family as used in the biological classification of living and fossil organisms as well as viruses . In binomial nomenclature , the genus name forms the first part of the binomial species name for each species within the genus.
51-558: The Elder Mother is an elder -guarding being in English and Scandinavian folklore known by a variety of names, such as the Danish Hyldemoer ( "Elder-Mother" ) and the Lincolnshire names Old Lady and Old Girl . The Elder Mother is thought to be the guardian of the elder trees, and it was said, until recent times in various parts of England and Scandinavia that to take wood from
102-576: A 100-gram ( 3 + 1 ⁄ 2 oz) amount, elderberries supply 305 kilojoules (73 kcal) of food energy and are a rich source of vitamin C , providing 43% of the Daily Value (DV). Elderberries also have moderate contents of vitamin B 6 (18% DV) and iron (12% DV), with no other nutrients in significant content. Elderberry fruit or flowers are used as dietary supplements to prevent or provide relief from minor diseases, such as flu , colds, constipation , and other conditions, served as
153-510: A mordant ) to give a "muted purple" shade. The berry of S. callicarpa can be made into wine . The flowers of S. nigra are used to produce elderflower cordial . St-Germain , a French liqueur, is made from elderflowers. Hallands Fläder, a Swedish akvavit , is flavoured with elderflowers. Hollowed elderberry twigs have traditionally been used as spiles to tap maple trees for syrup . Additionally, they have been hollowed out and used as flutes, blowguns, and syringes. In addition,
204-557: 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 ,
255-633: A group of 25 people in Monterey County, California , became ill after ingesting elderberry juice pressed from fresh, uncooked S. mexicana berries, leaves, and stems. The concentration of cyanogenic glycosides is higher in tea made from flowers (or leaves) than from the berries. The seeds of S. callicarpa are reported to be poisonous and may cause vomiting or diarrhea. The cooked berries (pulp and skin) of most species of Sambucus are edible. Raw elderberries are 80% water, 18% carbohydrates , and less than 1% each of protein and fat . In
306-576: A king and his knights (sometimes said to be Danes ). This is also the story of how the Rollright Stones that lie on the border between Oxfordshire and Warwickshire came to be. When the king and his knights marched towards Long Compton they came upon a witch who told the king: "Seven long strides thou shalt take, And if Long Compton thou shalt see, King of England thou shalt be." The king however went onwards saying: "Stick, stock, stone As King of England I shall be known." However, on
357-643: 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
408-621: 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,
459-409: 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
510-664: A strong fetid smell. Valley elderberry longhorn beetles in California are very often found around red or blue elderberry bushes. Females lay their eggs on the bark. Strong-scented flowers in wild populations of European elder ( S. nigra ) attract numerous, minute flower thrips which may contribute to the transfer of pollen between inflorescences. Traditional uses of Sambucus involved berries, seeds, leaves, and flowers or component extracts . Ornamental varieties of Sambucus are grown in gardens for their showy flowers, fruits and lacy foliage which support habitat for wildlife. Of
561-427: 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. ;

#1733084882440612-480: A tea, extract or in a capsule . The use of elderberry supplements increased early in the COVID-19 pandemic. There is insufficient research to establish its effectiveness for such uses, or its safety profile. The raw or unripe fruit of S. nigra or its extracts may contain a cyanogenic glycoside that is potentially toxic. Although practitioners of traditional medicine have used elderberry over centuries, there
663-455: 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
714-445: Is 5–30 centimetres (2–12 in) long, and the leaflets have serrated margins. They bear large clusters of small white or cream-colored flowers in late spring; these are followed by clusters of small black, blue-black, or red berries (rarely yellow or white). Sambucus fruit is rich in anthocyanidins that combine to give elderberry juice an intense blue-purple coloration that turns reddish on dilution with water. The taxonomy of
765-463: Is a nitrogen -dependent plant and thus is generally found near places of organic waste disposal. Elders are often grown as a hedgerow plant in Britain since they take very fast, can be bent into shape easily, and grow quite profusely, thus having gained the reputation of being 'an instant hedge'. It is not generally affected by soil type or pH level and will virtually grow anywhere sufficient sunlight
816-451: Is available. S. callicarpa berries are consumed by birds and mammals. In Northern California, elderberries are eaten by migrating band-tailed pigeons . Elders are used as food plants by the larvae of some Lepidoptera species including brown-tail , buff ermine , dot moth , emperor moth , engrailed moth , swallow-tailed moth and the V-pug . The crushed foliage and immature fruit have
867-596: 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
918-538: Is little high-quality clinical evidence that such practices provide benefits. The pigments are used as colorants in various products, and "elderberry juice color" is listed by the US Food and Drug Administration as allowable in certified organic food products. In Japan, elderberry juice is listed as an approved "natural color additive" under the Food and Sanitation Law. Fibers can be dyed with elderberry juice (using alum as
969-460: 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,
1020-474: 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
1071-421: Is thought that the tree had the power to ward off evil. In Sicily, it was claimed to have the power to ward off snakes. Elder (tree) See text Sambucus is a genus of flowering plants in the family Adoxaceae . The various species are commonly referred to as elder, elderflower or elderberry . The oppositely arranged leaves are pinnate with 5–9 leaflets (or, rarely, 3 or 11). Each leaf

#17330848824401122-551: Is thought to ward off evil and give protection from witches , while other beliefs say that witches often congregate under the plant, especially when it is full of fruit. If an elder tree was cut down, a spirit known as the Elder Mother would be released and take her revenge. The tree could only safely be cut while chanting a rhyme to the Elder Mother. Romani people believe burning elder wood brings bad luck. A wand made from
1173-621: 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
1224-799: 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;
1275-404: 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,
1326-553: The Elf-king and his host. A similar tradition existed in Scotland where it was said to happen on All Hallows or Samhain . In England, it was thought that the elder tree could never be hit by lightning and that carrying the twigs of an elder could protect their bearer from rheumatism. Farmers used to protect their animals from evil by placing a cross made from elder on their cow-sheds and barns. In some Slavic countries, such as Russia, it
1377-469: 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
1428-478: The King's seventh stride a hill rose up before Long Compton making him unable to see the town. The witch was there again with her chant: "As Long Compton thou canst not see King of England thou shalt not be. Rise up stick and stand still stone For King of England thou shalt be none; Thou and thy men hoar stones shall be And I myself an eldern tree." And thus the king and his knights were turned to stone and
1479-442: 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
1530-544: The branch of an elder tree plays a pivotal role in the final book of the Harry Potter series , which was almost named Harry Potter and the Elder Wand . 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
1581-403: The elder tree one would have to ask the Elder Mother first, or else ill luck would befall the woodsman. The woodsman would have to ask the Elder Mother like so: "Old girl, give me some of thy wood and I will give thee some of mine when I grow into a tree." One such story of the Elder Mother's revenge concerns a writer earlier in the 20th century. When calling in on the mother of a sick child,

1632-400: The elderberry twigs and fruit are employed in creating dyes for basketry. These stems are dyed a very deep black by soaking them in a wash made from the berry stems of the elderberry. The pith of elder has been used by watchmakers for cleaning tools before intricate work. Folklore related to elder trees is extensive and can vary according to region. In some traditions, the elder tree
1683-446: 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
1734-727: 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,
1785-691: The genus Adoxa . Species recognized in this genus are: The name comes from the Ancient Greek word σαμβύκη ( sambū́kē ), an ancient wind instrument, about the removal of pith from the twigs to make whistles. The genus occurs in temperate to subtropical regions of the world. More widespread in the Northern Hemisphere, its Southern Hemisphere occurrence is restricted to parts of Australasia and South America . Many species are widely cultivated for their ornamental leaves, flowers, and fruit. Elder commonly grows near farms and homesteads. It
1836-477: The genus Sambucus L. , originally described by Carl Linnaeus and hence its botanical authority , has been complicated by its wide geographical distribution and morphological diversity. This has led to overdescription of the species and infraspecific taxa ( subspecies , varieties or forms ). The genus was formerly placed in the honeysuckle family, Caprifoliaceae , but was reclassified as Adoxaceae due to genetic and morphological comparisons to plants in
1887-432: 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
1938-628: 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,
1989-625: The many native species, three are used as ornamentals: S. canadensis , S. nigra , and S. racemosa . The uncooked berries and other parts of plants from this genus are poisonous. Leaves, twigs, branches, seeds, roots, flowers, and berries of Sambucus plants produce cyanogenic glycosides , which have toxic properties. Ingesting a sufficient quantity of cyanogenic glycosides from berry juice, flower tea, or beverages made from fresh leaves, branches, and fruit has been shown to cause illness , including nausea , vomiting, abdominal cramps, diarrhea , and weakness. In August 1983,
2040-403: 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
2091-461: The mother told him: "It were all along of my maister’s thick ‘ead. It were in this ‘ow't’ rocker comed off t'cradle, and he hadn’t no more gumption than to mak’ a new ‘un out on illerwood (elder wood) without axing the Old Lady’s leave, and in course she didn’t like that, and she came and pinched the wean that outrageous he were a’most black in t’ face; but I bashed un off, and putten an eshen on, and

2142-428: 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
2193-526: 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
2244-497: 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,
2295-412: 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
2346-403: 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
2397-566: 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
2448-429: 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
2499-401: The wean is gallus as owt agin." Another tale, from Somerset, casts the Elder Mother as the villain, a witch that a farmer sees as an elder milking his cow. The farmer shoots at the witch with a silver bullet but misses and is chased back into the farmhouse . The old granny , however, picks up the burning coal from the fire with a shovel and throws it at the elder tree, burning cinders, and thus
2550-433: The witch is dead. A tale from Northamptonshire tells of man who cut a stick from an elder, and saw that the tree was bleeding. Later he meets the local witch and sees that she has a bloodied bandage on her arm. Another tale not only has the elder-tree witch (sometimes later claimed to be various famous characters such as Mother Shipton ) as the somewhat dubious heroine, but also with saving England from being conquered by
2601-619: The witch turned herself into an elder tree. In Denmark, the Hyldemoer (“Elder-mother”) or Hyldequinde (“Elder-woman”) is a spirit like a wood-nymph or dryad that lives in the elder tree . The spirit is said to haunt or torment people who build from elder wood unless they ask permission first. In Denmark, an elder twig put in the mouth was traditionally thought to drive out evil spirits and thus could cure toothache. Also in Denmark, if you were to stand under an elder on Midsummer 's Eve you could see
