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.
69-617: Jubaea is a genus of palms with one species, Jubaea chilensis , commonly known in English as the Chilean wine palm or Chile cocopalm , and palma chilena in Spanish. It is native to southwestern South America and is endemic to a small area of central Chile between 32°S and 35°S in southern Coquimbo , Valparaíso , Santiago , O'Higgins , and northern Maule regions. The extinct palm tree of Easter Island belonged to this genus as well. In 1991,
138-407: A clustering habit results. Exclusively sympodial genera include many of the rattans , Guihaia , and Rhapis . Several palm genera have both solitary and clustering members. Palms which are usually solitary may grow in clusters and vice versa. Palms have large, evergreen leaves that are either palmately ('fan-leaved') or pinnately ('feather-leaved') compound and spirally arranged at the top of
207-407: 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
276-458: A large amount of the human diet and several other human uses, both by absolute amount produced and by number of species domesticated . This is far higher than almost any other plant family, sixth out of domesticated crops in the human diet, and first in total economic value produced – sharing the top spot with the Poaceae and Fabaceae . These human uses have also spread many Arecaceae species around
345-643: 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

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,
483-409: 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
552-427: 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. ;
621-455: 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
690-617: A variety of different habitats. Their diversity is highest in wet, lowland forests. South America , the Caribbean , and areas of the South Pacific and southern Asia are regions of concentration. Colombia may have the highest number of palm species in one country. There are some palms that are also native to desert areas such as the Arabian Peninsula and parts of northwestern Mexico. Only about 130 palm species naturally grow entirely beyond
759-609: A water source, and in desert oases such as the date palm . A few palms are adapted to extremely basic lime soils, while others are similarly adapted to extreme potassium deficiency and toxicity of heavy metals in serpentine soils . Palms are a monophyletic group of plants, meaning the group consists of a common ancestor and all its descendants. Extensive taxonomic research on palms began with botanist H.E. Moore , who organized palms into 15 major groups based mostly on general morphological characteristics. The following classification, proposed by N.W. Uhl and J. Dransfield in 1987,

#1732855532637828-508: Is a revision of Moore's classification that organizes palms into 6 subfamilies. A few general traits of each subfamily are listed below. The Phytelephantoideae is the sixth subfamily of Arecaceae in N.W. Uhl and J. Dransfield's 1987 classification. Members of this group have distinct monopodial flower clusters. Other distinct features include a gynoecium with five to 10 joined carpels, and flowers with more than three parts per whorl. Fruits are multiple-seeded and have multiple parts. From

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
966-595: Is from Dravidian *aṭ-ay-kkāy ("areca nut"). The suffix -aceae is the feminine plural of the Latin -āceus ("resembling"). Palm originates from Latin palma semantically overlapping with sense of " hand front " (due to similar splayed shape) ultimately from Proto-Indo-European * pl̥h₂meh₂ , a direct descendant folm once existed in Old English. Whether as shrubs, tree-like, or vines, palms have two methods of growth: solitary or clustered. The common representation
1035-496: Is often called "anomalous secondary growth". The Arecaceae are notable among monocots for their height and for the size of their seeds, leaves, and inflorescences. Ceroxylon quindiuense , Colombia's national "tree", is the tallest monocot in the world, reaching up to 60 metres (197 ft) tall. The coco de mer ( Lodoicea maldivica ) has the largest seeds of any plant, 40–50 centimetres (16–20 in) in diameter and weighing 15–30 kilograms (33–66 lb) each ( coconuts are
1104-662: Is possible north of subtropical climates, and some higher latitude locales such as Ireland, Scotland, England, and the Pacific Northwest feature a few palms in protected locations and microclimates . In the United States , there are at least 12 native palm species, mostly occurring in the states of the Deep South and Florida . Palms inhabit a variety of ecosystems. More than two-thirds of palm species live in humid moist forests, where some species grow tall enough to form part of
1173-460: 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,
1242-460: Is that of a solitary shoot ending in a crown of leaves. This monopodial character may be exhibited by prostrate, trunkless, and trunk-forming members. Some common palms restricted to solitary growth include Washingtonia and Roystonea . Palms may instead grow in sparse though dense clusters. The trunk develops an axillary bud at a leaf node, usually near the base, from which a new shoot emerges. The new shoot, in turn, produces an axillary bud and
1311-474: 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
1380-516: Is very large, and of a curious form, being thicker in the middle than at the base or top. In 1843, a specimen was grown from seed at Kew Gardens , London, England, and was moved into the Temperate House in 1863, eventually growing to 19 metres (62 ft). It was believed to be the world's tallest indoor plant, until it had to be felled in 2013 because it had outgrown the space available and could not be moved. It has been replaced by seedlings from
1449-563: The Adelaide (South Australia) Botanic Garden in 1889 was stated to be 6 feet (1.8 m) thick at the base. A hollow (but living) Jubaea in the Ocoa Valley near La Campana National Park , Chile, is 6 to 7 feet (1.8 to 2.1 m) thick at its base, with no apparent taper in the lower trunk. The largest individual specimen of indoor plant in the world was the Jubaea chilensis at Kew Gardens , which

The Arecaceae were the first modern family of monocots to appear in the fossil record around 80 million years ago (Mya), during the late Cretaceous period. The first modern species, such as Nypa fruticans and Acrocomia aculeata , appeared 69 Mya, as evidenced by fossil Nypa pollen. Palms appear to have undergone an early period of adaptive radiation . By 60 Mya, many of
1587-621: 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
1656-799: 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;
1725-569: The canopy and shorter ones form part of the understory . Some species form pure stands in areas with poor drainage or regular flooding, including Raphia hookeri which is common in coastal freshwater swamps in West Africa. Other palms live in tropical mountain habitats above 1 thousand metres (3 thousand feet), such as those in the genus Ceroxylon native to the Andes . Palms may also live in grasslands and scrublands, usually associated with

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,
1932-640: The Ceroxyloideae and Phytelephantoideae. Studies have suggested the lack of a fully resolved hypothesis for the relationships within the family is due to a variety of factors, including difficulties in selecting appropriate outgroups, homoplasy in morphological character states, slow rates of molecular evolution important for the use of standard DNA markers , and character polarization. However, hybridization has been observed among Orbignya and Phoenix species, and using chloroplast DNA in cladistic studies may produce inaccurate results due to maternal inheritance of

In its area of natural distribution, young Jubaea s tend to grow near adult specimens, preferring also sunny and vegetated sites. The thickest well-documented Jubaea was on the estate of J. Harrison Wright in Riverside, California . Its diameter "at shoulder height" was 66 inches (1.7 m). The largest of several specimens at

In many historical cultures, because of their importance as food, palms were symbols for such ideas as victory, peace, and fertility. The word Arecaceae is derived from the word areca with the suffix "-aceae". Areca is derived from Portuguese , via Malayalam അടയ്ക്ക ( aṭaykka ), which

In 2006, at least 100 palm species were considered endangered, and nine species have been reported as recently extinct. However, several factors make palm conservation more difficult. Palms live in almost every type of warm habitat and have tremendous morphological diversity. Most palm seeds lose viability quickly, and they cannot be preserved in low temperatures because

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
2415-407: The base. The stamens generally number six, with filaments that may be separate, attached to each other, or attached to the pistil at the base. The fruit is usually a single- seeded drupe (sometimes berry-like) but some genera (e.g., Salacca ) may contain two or more seeds in each fruit. Like all monocots , palms do not have the ability to increase the width of a stem ( secondary growth ) via
2484-466: The chloroplast DNA. Chemical and molecular data from non-organelle DNA, for example, could be more effective for studying palm phylogeny. Recently, nuclear genomes and transcriptomes have been used to reconstruct the phylogeny of palms. This has revealed, for example, that a whole-genome duplication event occurred early in the evolution of the Arecaceae lineage, that was not experienced by its sister clade,
2553-493: The cold kills the embryo. Using botanical gardens for conservation also presents problems, since they can rarely house more than a few plants of any species or truly imitate the natural setting. There is also the risk that cross-pollination can lead to hybrid species. The Palm Specialist Group of the World Conservation Union (IUCN) began in 1984, and has performed a series of three studies to find basic information on

An indication of the importance of palms in ancient times is that they are mentioned more than 30 times in the Bible , and at least 22 times in the Quran . The Torah also references the "70 date palm trees", which symbolize the 70 aspects of Torah that are revealed to those who "eat of its fruit." Arecaceae have great economic importance, including coconut products, oils, dates, palm syrup , ivory nuts, carnauba wax, rattan cane, raffia, and palm wood . This family supplies

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

Early Christians used the palm branch to symbolize the victory of the faithful over enemies of the soul, as in the Palm Sunday festival celebrating the triumphal entry of Jesus Christ into Jerusalem . In Judaism , the palm represents peace and plenty, and is one of the Four Species of Sukkot ; the palm may also symbolize the Tree of Life in Kabbalah . The canopies of

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,

2898-500: The habitat, and those with small habitat ranges are most vulnerable to them. The harvesting of heart of palm, a delicacy in salads, also poses a threat because it is derived from the palm's apical meristem , a vital part of the palm that cannot be regrown (except in domesticated varieties, e.g. of peach palm ). The use of rattan palms in furniture has caused a major population decrease in these species that has negatively affected local and international markets, as well as biodiversity in
2967-432: The history of the Middle East and North Africa. In the text "Date Palm Products" (1993), W.H. Barreveld wrote: One could go as far as to say that, had the date palm not existed, the expansion of the human race into the hot and barren parts of the "old" world would have been much more restricted. The date palm not only provided a concentrated energy food, which could be easily stored and carried along on long journeys across
3036-628: 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,
3105-673: The modern phylogenomic data, the Phytelephantoideae are tribe in the Ceroxyloideae subfamily. Currently, few extensive phylogenetic studies of the Arecaceae exist. In 1997, Baker et al. explored subfamily and tribe relationships using chloroplast DNA from 60 genera from all subfamilies and tribes. The results strongly showed the Calamoideae are monophyletic, and Ceroxyloideae and Coryphoideae are paraphyletic. The relationships of Arecoideae are uncertain, but they are possibly related to
3174-660: The modern, specialized genera of palms appeared and became widespread and common, much more widespread than their range today. Because palms separated from the monocots earlier than other families, they developed more intrafamilial specialization and diversity. By tracing back these diverse characteristics of palms to the basic structures of monocots, palms may be valuable in studying monocot evolution. Several species of palms have been identified from flowers preserved in amber, including Palaeoraphe dominicana and Roystonea palaea . Fossil evidence of them can also be found in samples of petrified palmwood . The relationship between
3243-403: 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

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

Their growth form can be climbers , shrubs , tree -like and stemless plants, all commonly known as palms . Those having a tree-like form are colloquially called palm trees . Currently, 181 genera with around 2,600 species are known, most of which are restricted to tropical and subtropical climates. Most palms are distinguished by their large, compound, evergreen leaves, known as fronds , arranged at
3450-468: The palm Endangered . A recent study concluded that predation of the fruits by humans, the seeds by the exotic rat ( Rattus rattus ) and the young seedlings by exotic rabbits is leading to seed dispersal collapse of this species, leaving it at risk of extinction in its natural habitat. Charles Darwin examined these trees on visiting Chile in 1832 on the second voyage of HMS Beagle and noted: These palms are, for their family, ugly trees. Their trunk
