56-649: Phragmites ( / f r æ ɡ ˈ m aɪ t iː z / ) is a genus of four species of large perennial reed grasses found in wetlands throughout temperate and tropical regions of the world. The World Checklist of Selected Plant Families, maintained by Kew Garden in London , accepts the following four species: Phragmites stands can provide food and shelter resources for a number of birds, insects, and other animals. Habitat benefits are often optimal when stands are thinner, and management of stands may promote more suitable habitat benefits. Some evidence suggests that

112-501: A broom to life to do his chore of filling a well full of water. The broom overdoes its job and when chopped into pieces, each splinter becomes a new broom that flood the room until Yen Sid stops them. This story comes from a poem by Goethe called Der Zauberlehrling ("The Sorcerer's Apprentice"). The Disney brooms have had recurring cameos in Disney media, mostly portrayed as janitors, albeit not out of control or causing chaos such as in

168-407: 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 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

224-408: A high speed. This is not to be confused with other double reeds like that of the oboe which uses two reeds made from the giant reed leaning against each other. The leaves, roots, seeds and stems of phragmites are edible. Young shoots can be cooked or eaten raw just like bamboo shoots. The young stems, "while still green and fleshy, can be dried and pounded into a fine powder, which when moistened

280-530: A large amount of decaying dead plant material can depress oxygen levels in the water and kill all the fish in a pond or small lake. Some success has also been obtained using goats to graze on Phragmites , controlled burns, and native wild rice crops. Biological controls have been suggested to be the most likely control method to succeed and biocontrols have been approved for introduction in North America Unfortunately, biocontrols may destroy

336-651: 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

392-628: 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,

448-508: A major center for broom production because broom corn grew especially well there, with The Oklahoma Broom Corn Company opening a factory in El Reno in 1906. Faced with competition from imported brooms and synthetic bristles, most of the factories closed by the 1960s. In the context of witchcraft , broomstick is likely to refer to the broom as a whole, known as a besom . The first known reference to witches flying on broomsticks dates to

504-409: 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

560-408: A short term management rotation of 1–2 years could maximize bird and invertebrate numbers. P. australis provides ecosystem services such as nutrient sequestration, soil stabilization, and waste treatment. It has been suggested that due to its resilience to climate change impacts, P. australis may provide beneficial ecosystem services that need to be considered in coastal ecosystems, even where it

616-427: 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. ;

672-455: 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

728-679: Is an abundant invasive species. In the United States, prior to 1910, only a few areas in the Northeast contained non-native haplotypes of Phragmites australis. However, by 1960 non-native haplotypes were found in samples taken from coast to coast. Today, in some places like Michigan, Phragmites australis ( haplotype M) has become the dominant haplotype. The problem is invasive non-native Phragmites australis quickly spread through marshes and wetland areas. They replace native plants, deny fish and wildlife nutrients and space; block access to

784-408: Is considered an invasive species. Others have argued that the ecosystem services lost as a result of invasion outweigh the benefits gained and managers need to be responsive to invasion control. P. australis is cultivated as an ornamental plant in aquatic and marginal settings such as pond- and lakesides. Its aggressive colonisation means it must be sited with care. Phragmites australis is one of

840-612: 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

896-474: Is nearly impossible. The seeds or rhizomes can quickly lead to a new dense stand. Chemical treatment is by far the most utilized method in North America [1] . The two most common active ingredients in herbicides for Phragmites control are glyphosate and imazapyr. It is important to select the proper herbicide for the location. Further, even the proper herbicide can lead to unintended consequences since

952-598: Is roasted like marshmallows." The seeds and rhizomes "can be ground into flour or made into gruel." In Japan, young leaves are dried, ground, and then mixed with cereal flour to make dumplings. Grazing on phragmites by large-bodied domestic herbivores, such as cows, horses, sheep, and goats, can effectively control the plant and provide a reciprocal positive benefit for humans by generating meat, milk, leather, and wool etc. Some other uses for Phragmites australis and other reeds in various cultures include baskets , mats, reed pen tips ( qalam ), and paper. Beekeepers can utilize

1008-460: 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,

1064-474: 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

1120-424: Is used to create a small instrument similar to the clarinet called a sipsi , with either a single, as in the picture, or double pipes as in bagpipes. The reed of the zurna is made from the common reed which is flattened after removing its brittle outer glaze and the loose inner membrane, and after softening it by wetting. The result is a double reed with an elliptical opening that vibrates by closing and opening at

1176-621: 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

1232-824: 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;

1288-419: 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 ,

1344-514: The nutrients in biotransformation . The water is then suitable for irrigation , groundwater recharge , or release to natural watercourses. Reed is used in many areas for thatching roofs. In the British Isles , common reed used for this purpose is known as Norfolk reed or water reed. However, "wheat reed" and "Devon reed", also used for thatching, are not in fact reed, but long-stemmed wheat straw. In Middle East countries Phragmites

1400-404: 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,

1456-530: The 11th-century Islamic traditionalist theologian Ibn Qudamahin his book al-Mughnī ( The Persuader ). The first reference to witches flying on broomsticks in Europe dates to 1453, confessed by the male witch Guillaume Edelin . The concept of a flying ointment used by witches appears at about the same time, recorded in 1456. In Metro-Goldwyn-Mayer 's 1939 film, The Wizard of Oz , the Wicked Witch of

1512-568: The Earth, and yet with all his Faults, he sets up to be an universal Reformer and Corrector of Abuses, a Remover of Grievances, rakes into every Sluts Corner of Nature, bringing hidden Corruptions to the Light, and raises a mighty Dust where there was none before, sharing deeply all the while, in the very same Pollutions he pretends to sweep away: His last Days are spent in Slavery to Women, and generally

1568-806: The West used a broomstick to fly over Oz . She also used it to skywrite " Surrender Dorothy " above the Emerald City . The Wizard commands Dorothy and her three traveling companions to bring the Wicked Witch's broomstick to him in order to grant their wishes. Dorothy carries it to the Wizard with the Scarecrow , Tin Man , and Lion after the Wicked Witch's death. In Disney 's 1940 film Fantasia , Mickey Mouse , playing The Sorcerer's Apprentice , brings

1624-442: 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

1680-543: The broomstick. It is thus a variety of brush with a long handle. It is commonly used in combination with a dustpan . A distinction is made between a "hard broom" and a "soft broom" and a spectrum in between. Soft brooms are used in some cultures chiefly for sweeping walls of cobwebs and spiders , like a " feather duster ", while hard brooms are for rougher tasks like sweeping dirt off sidewalks or concrete floors, or even smoothing and texturing wet concrete . The majority of brooms are somewhere in between, suitable for sweeping

1736-418: The chemicals they produce when decaying reduce the germination of competing seeds. Among other effects, the monocultures that result from invasion decrease spatial and temporal habitat heterogeneity and increase avian homogeneity. Recognizing the non-native form of Phragmites early in its invasion increases the opportunity for successful eradication dramatically. Once it has become established, removal by hand

1792-486: The earlier besom during the Early Modern English period. The song Buy Broom Buzzems (by William Purvis 1752–1832) still refers to the "broom besom" as one type of besom (i.e. "a besom made from broom"). Flat brooms, made of broom corn , were invented by Shakers in the 19th century with the invention of the broom vice . A smaller whisk broom or brush is sometimes called a duster. In 1797,

1848-534: The floors of homes and businesses, soft enough to be flexible and to move even light dust, but stiff enough to achieve a firm sweeping action. The broom is also a symbolic object associated with witchcraft and ceremonial magic . The word "broom" derives from the name of certain thorny shrubs ( Genista and others) used for sweeping. The name of the shrubs began to be used for the household implement in Late Middle English and gradually replaced

1904-623: The foot treadle broom machine was invented. This machine played an integral part in the Industrial Revolution . One source mentions that the United States had 303 broom factories by 1839 and that the number peaked at 1,039 in 1919. Most of these were in the Eastern United States ; during the Great Depression in the 1930s, the number of factories declined to 320 in 1939. The state of Oklahoma became

1960-446: 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

2016-737: 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,

2072-633: 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,

For much of the 20th century, political cartoons and propaganda would often depict new or oncoming leaders sweeping away old, corrupt or unpopular figures. The broom is used as a symbol of the following political parties: 16. " Brooms " (in crypto) are

2184-404: 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. Broom A broom (also known as a broomstick ) is a cleaning tool consisting of usually stiff fibers (often made of materials such as plastic, hair, or corn husks) attached to, and roughly parallel to, a cylindrical handle,

2240-547: The main means of transportation in the world of Poul Anderson 's Operation Chaos . The Flying Broom ( Turkish : Uçan Süpürge ) is a feminist organization in Turkey , deliberately evoking the associations of a Flying Broom with witches. But a Broom-Stick, perhaps you will say, is an Emblem of a Tree standing on its Head; and pray what is Man, but a Topsy-turvey Creature, his Animal Faculties perpetually mounted on his Rational; His Head where his Heels should be, groveling on

2296-420: The main wetland plant species used for phytoremediation water treatment. Waste water from lavatories and greywater from kitchens is routed to an underground septic tank-like compartment where the solid waste is allowed to settle out. The water then trickles through a constructed wetland or artificial reed bed, where bioremediation bacterial action on the surface of roots and leaf litter removes some of

2352-403: 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

2408-428: 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

2464-457: The native subspecies population as well. When cutting under water, cutting and then flooding, or burning and then flooding, it is important that the entire Phragmites stand is completely submerged so that the plants cannot obtain oxygen. Biocontrol using two species of moth larvae (Lenisa geminipuncta and Archanara neurica) is being investigated in Ontario . Genus The composition of

2520-488: The original appearance. This flight was also in Bedknobs and Broomsticks as well as Hocus Pocus . In Eswatini (Swaziland) , witches' broomsticks are short bundles of sticks tied together without a handle. Flying brooms play an important role in the fantasy world of Harry Potter , used for transportation as well as for playing the popular airborne game of Quidditch . Flying brooms, along with Flying carpets , are

2576-541: 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

2632-510: The quality of brooms changed when Levi Dickenson, a farmer in Hadley, Massachusetts , made a broom for his wife, using the tassels of sorghum , a grain he was growing for the seeds. His wife spread good words around town, creating demand for Dickenson's sorghum brooms. The sorghum brooms held up well, but ultimately, like all brooms, fell apart. Dickenson subsequently invented a machine that would make better brooms, and faster than he could. In 1810,

2688-589: The reeds to make nesting. In the Philippines , Phragmites is known by the local name tambo . Reed stands flower in December, and the blooms are harvested and bundled into whisk brooms called "walis". Hence the common name of household brooms is walis tambo . Reeds have been used to make arrows and weapons such as spears for hunting game. Some Phragmites , when introduced by accident or intent, spread rapidly. In tropics and subtropics, Phragmites karka

2744-470: 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 the French botanist Joseph Pitton de Tournefort (1656–1708) is considered "the founder of the modern concept of genera". The scientific name (or

2800-408: 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 a species : see Botanical name and Specific name (zoology) . The rules for the scientific names of organisms are laid down in

2856-497: 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,

2912-412: 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

2968-403: 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

3024-576: 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

3080-429: 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

Phragmites also alters wetland biogeochemistry and affects both floral and faunal species assemblages, including potentially reducing nitrogen and phosphorus availability for other plants. Phragmites can drive out competing vegetation in two main ways. Their sheer height and density can deprive other plants of sunlight and
