45-573: Vanda , abbreviated in the horticultural trade as V. , is a genus in the orchid family, Orchidaceae . There are 90 species, and the genus is commonly cultivated for the marketplace. This genus and its allies are considered to be among the most specifically adapted of all orchids within the Orchidaceae. The genus is highly prized in horticulture for its showy, fragrant, long-lasting, and intensely colorful flowers. Vanda species are widespread across East Asia , Southeast Asia , and New Guinea , with

90-551: A monopodial growth habit with flat, typically broad, ovoid leaves (strap-leaves). Species with cylindrical (terete), fleshy leaves, which are adapted to dry periods were transferred to the genus Papilionanthe . The stems of these orchids vary considerably in size; some are miniature plants and some have a length of several meters. The plants can become quite massive in habitat and in cultivation, and epiphytic species possess very large, rambling aerial root systems. The roots have pneumatodes . The few to many flattened flowers grow on

135-632: A few species extending into Queensland and some of the islands of the western Pacific . The generic name Vanda is derived from the Sanskrit (वन्दाका) name for the species Vanda roxburghii (a synonym of Vanda tessellata ). These mostly epiphytic , but sometimes lithophytic or terrestrial orchids, are distributed in India , Himalaya , Southeast Asia , Indonesia , the Philippines , New Guinea , southern China , and northern Australia . The genus has

180-440: A group of tropical epiphyte orchids that grow mainly in the warm lowlands of tropical Asia from India to southern China to New Guinea. They are valued in horticulture for their racemes of showy, fragrant, colorful flowers. The name of the genus refers to the epiphytic growth habit of the species, and literally means "air-plant". The type species , Aerides odorata , was described by João de Loureiro in 1790. This genus

225-643: 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

270-770: A lateral inflorescence . Most show a yellow-brown color with brown markings, but they also appear in white, green, orange, red, and burgundy shades. The lip has a small spur. Vanda species usually bloom every few months and the flowers last for two to three weeks. Vanda falcata has been reported to be pollinated by several hawkmoth species of the genus Theretra , namely Theretra japonica and Theretra nessus . Many Vanda orchids (especially V. coerulea ) are endangered, and have never been common because they are usually only infrequently encountered in habitat and grow only in disturbed forest areas with high light levels, and are severely threatened and vulnerable to habitat destruction . The export of wild-collected specimens of

315-621: 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,

360-409: 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

405-478: A sharp, stout, leafy stem . The leaves are distichous, growing in two vertical rows. The leaf margins are bilobed, and the apex is emarginate. There are ligules. Morphologically, they are very similar to species in the genus Vanda . The genus grows in the tropics of Asia, in India , Nepal , southern China , Southeast Asia , the Philippines , and New Guinea . They flower from June to July. Temperature requirements vary from cool to warm growing depending on

450-427: 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. ;

495-455: 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

540-434: Is abbreviated Aer in the horticultural trade. The species in this genus range from small to large monopodial epiphytes, except for Aerides krabiensis , which is a lithophyte . They form pendulous racemes with many long-lasting, fragrant, waxy flowers , which are often white with purple or pink edges. Some species have purple or pink flowers, and a few have yellow. Each flower has a forward-facing spur and grows on

585-596: 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

630-578: Is in charge of the International Orchid Register: 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 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

675-460: 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,

720-474: 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

765-621: 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

810-799: 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;

855-419: 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 ,

900-404: 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,

945-503: The World Online as of January 2023: The following is a list of hybrid genera (nothogenera) in which hybrids vandas with orchids of other genera are placed although many of these are invalid because of recent taxonomic changes. For instance, × Ascocenda ( Ascocentrum x Vanda ) and × Vandofinetia ( Vanda x Neofinetia ) are no longer valid because both Ascocentrum and Neofinetia have been reduced to synonyms of Vanda by RHS, which

990-442: 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

1035-547: The blue orchid ( V. coerulea ) and other wild Vanda species is prohibited worldwide, as all orchids are listed on Appendix II of the Convention on International Trade in Endangered Species . This genus is one of the five most horticulturally important orchid genera, because it has some of the most magnificent flowers to be found in the orchid family. This has contributed much to the work of hybridists producing flowers for

1080-400: The cut flower market. V. coerulea is one of the few botanical orchids which can produce varieties with blue flowers (actually a very bluish purple), a property much appreciated for producing interspecific and intergeneric hybrids. The color blue is rare among orchids, and only certain species of Thelymitra , a terrestrial species from Australia, produces flowers that are truly "blue" among

1125-446: 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

1170-727: 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,

1215-628: 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,

1260-469: The like provided they are given some shade. Unfortunately fungal infections are not uncommon in cultivated plants. A variety of phytopathogens may infect Vanda orchids. Vandas may be affected by Fusarium wilt . This disease is characterized by purple discolouration in the vascular tissue, which results in the loss of their function. The hyphae and spores block the conductor vessels. Affected plants may superficially appear healthy, as they continue to grow,

1305-401: 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. Aerides Aerides , known commonly as cat's-tail orchids and fox brush orchids , is a genus belonging to the orchid family ( Orchidaceae , subfamily Epidendroideae , tribe Vandeae , subtribe Aeridinae ). It is

1350-403: 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

1395-428: 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

1440-441: The oldest parts of the plants can be affected and the disease will eventually progress throughout the entire plant. If cutting tools are not sterilized the infection may spread to other plants. In a recent molecular study of the genus Vanda , several Genera including the former Genus Ascocentrum , Neofinetia and Euanthe were brought into synonym with Vanda . The following is a list of Vanda species recognised by Plants of

1485-474: The orchids. These species, much like Vanda , also have a bluish-purple tint towards the inner petals of the flowers. Vanda dearei is one of the chief sources of yellow color in Vanda hybrids. The plants do not possess pseudobulbs, but do possess leathery, drought-resistant leaves. Almost all of the species in this genus are very large epiphytes found in disturbed areas in habitat and prefer very high light levels,

1530-412: The plants having large root systems. Some of these species have a monopodial vine-like growth habit, and the plants can quickly become quite massive. These plants prefer consistent conditions day-to-day in cultivation to avoid dropping their bottom leaves. The epiphytic species are best accommodated in large wooden baskets, bare rooted, which allows for the large aerial root systems. Disturbing or damaging

1575-526: 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

1620-598: The roots of large, mature vandaceous orchid plants, and in particular, Vanda and Aerides species, can result in the plants failing to flower and going into decline for a season or more. These plants do not tolerate disturbance or damage of their root systems in cultivation when they become mature. The terete-leaved terrestrial species are very easy to cultivate. When grown bare-rooted, the epiphytic species require daily watering and weekly feeding and are very heavy feeders in cultivation. They can be grown out-of-doors in Hawaii and

1665-468: The roots. The plants do not tolerate disturbance or damage of their root systems in cultivation. The plants do not have pseudobulbs . The leaves are leathery and drought-resistant. Many of these species have a monopodial vine-like growth habit, and the plants can quickly grow large. The following species are recognized as of June 2014, all monopodial epiphytic plants except the lithophyte A. krabiense . Natural hybrids include Aerides × jansonii ,

1710-466: 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

1755-408: 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

1800-470: The species. Most Aerides species are considered easy to grow. Their flowers are fragrant and long-lived, which make them popular in horticulture as cut flowers and potted plants. Aerides can be kept in hanging baskets , teak containers or net pots, which allow the roots to extend into the air. They grow best in well-drained media, such as tree fern fibers, fir bark, and sphagnum moss . They require full sunlight, warm temperatures, and water applied to

1845-497: 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,

1890-412: 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

1935-403: 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

1980-566: 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

2025-429: 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
