Most palms are distinguished by their large, compound, [[evergreen]] leaves, known as [[frond]]s, arranged at the top of an unbranched stem, except for the [[Hyphaene]] genus, who has branched palms. However, palms exhibit an enormous diversity in physical characteristics and inhabit nearly every type of [[Habitat (ecology)|habitat]] within their range, from [[rainforest]]s to [[desert]]s.

Palms are among the best known and most extensively [[Horticulture|cultivated]] plant families. They have been important to humans throughout much of history, especially in regions like the Middle East and North Africa. A wide range of common products and foods are derived from palms. In contemporary times, palms are also widely used in landscaping. In many historical cultures, because of their importance as food, palms were [[Palm branch (symbol)|symbols]] for such ideas as victory, peace, and fertility.

==Etymology==
The word ''Arecaceae'' is derived from the word ''[[areca]]'' with the suffix "-aceae". ''Areca'' is derived from [[Portuguese language|Portuguese]], via [[Malayalam]] അടയ്ക്ക (''aṭaykka''), which is from [[Dravidian languages|Dravidian]] ''*aṭ-ay-kkāy'' ("areca nut"). The suffix ''-aceae'' is the feminine plural of the Latin ''-āceus'' ("resembling").{{cn|date=February 2025}}

''Palm'' originates from [[Latin]] ''palma'' semantically overlapping with sense of "[[Hand#Areas|hand front]]" (due to similar splayed shape) ultimately from [[Proto-Indo-European language|Proto-Indo-European]] *''pl̥h₂meh₂'', a direct descendant {{wikt-lang|en|folm}} once existed in Old English.<ref>{{Cite book |last1=Mallory |first1=James P. |title=Encyclopedia of Indo-European culture |last2=Adams |first2=Douglas Q. |date=1997 |publisher=Fitzroy Dearborn |isbn=1-884964-98-2 |location=Chicago |page=255}}</ref>

==Morphology==
Whether as shrubs, tree-like, or vines, palms have two methods of growth: solitary or clustered. The common representation 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 a clustering habit results. Exclusively [[sympodial]] genera include many of the [[rattan]]s, ''[[Guihaia]]'', and ''[[Rhapis]]''. Several palm genera have both solitary and clustering members. Palms which are usually solitary may grow in clusters and vice versa.<ref name="uhl">{{Cite book |last1=Uhl |first1=Natalie W. |title=Genera Palmarum – A classification of palms based on the work of Harold E. Moore |last2=Dransfield |first2=John |publisher=[[Allen Press]] |year=1987 |isbn=978-0-935868-30-2 |location=Lawrence, Kansas}}</ref>

Palms have large, evergreen leaves that are either palmately ('fan-leaved') or pinnately ('feather-leaved') compound and spirally (-alternately) arranged at the top of the stem, with the sole exception of the King Raphia (''[[Raphia vinifera]]'' variety ''nigerica'') which has opposite pairs of fronds).  The leaves have a tubular sheath at the base that usually splits open on one side at maturity.<ref>{{Cite web |title=Arecaceae (Palmae) |url=http://www.botany.hawaii.edu/faculty/carr/arec.htm |url-status=dead |archive-url=https://web.archive.org/web/20060424052701/http://www.botany.hawaii.edu/faculty/carr/arec.htm |archive-date=April 24, 2006 |website=Botany Department [[University of Hawaiʻi]]}}</ref> The [[inflorescence]] is a [[spadix (botany)|spadix]] or [[spike (botany)|spike]] surrounded by one or more [[bract]]s or [[spathe]]s that become woody at maturity. The [[flower]]s are generally small and white, radially symmetric, and can be either uni- or bisexual. The sepals and petals usually number three each and may be distinct or joined at 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-[[seed]]ed [[drupe]] (sometimes berry-like)<ref>{{eFloras|1|10061|Arecaceae |first=Scott |last=Zona |volume=22 |archive-url=https://web.archive.org/web/20060525043634/http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=10061 |archive-date=2006-05-25}}</ref> but some genera (e.g., ''[[Salacca]]'') may contain two or more seeds in each fruit.

[[File:Palm tree trunk.JPG|thumb|left|Sawn palm stem: Palms do not form annual [[tree rings]].]]

Like all [[monocot]]s, palms do not have the ability to increase the width of a stem ([[secondary growth]]) via the same kind of [[vascular cambium]] found in non-monocot [[woody plant]]s.<ref>{{Cite journal |last=Chase |first=Mark W. |author-link=Mark Wayne Chase |date=2004 |title=Monocot relationships: an overview |journal=[[American Journal of Botany]] |volume=91 |issue=10 |pages=1645–1655 |doi=10.3732/ajb.91.10.1645 |pmid=21652314 |doi-access=free}}</ref> This explains the cylindrical shape of the trunk (almost constant diameter) that is often seen in palms, unlike in [[Tree ring|ring]]-forming trees. However, many palms, like some other monocots, do have secondary growth, although because it does not arise from a single vascular cambium producing [[xylem]] inwards and phloem outwards, it is often called "anomalous secondary growth".<ref>{{Cite journal |last=Donoghue |first=Michael J. |year=2005 |title=Key innovations, convergence, and success: macroevolutionary lessons from plant phylogeny |url=http://www.phylodiversity.net/donoghue/publications/MJD_papers/2005/149_MJD_Paleo05.pdf |url-status=usurped |journal=Paleobiology |volume=31 |issue=sp5 |pages=77–93 |doi=10.1666/0094-8373(2005)031[0077:KICASM]2.0.CO;2 |s2cid=36988476 |archive-url=https://web.archive.org/web/20110723090605/http://www.phylodiversity.net/donoghue/publications/MJD_papers/2005/149_MJD_Paleo05.pdf |archive-date=2011-07-23}}</ref>

==Range and habitat==

[[File:Washingtonia filifera in Palm Canyon.jpg|thumb|This grove of the native species ''[[Washingtonia filifera]]'' in Palm Canyon, just south of [[Palm Springs, California|Palm Springs]], [[California]], is growing alongside a stream running through the desert.]]

Most palms are native to tropical and subtropical climates. Palms thrive in moist and hot climates but can be found in a variety of different habitats. Their diversity is highest in wet, lowland forests. [[South America]], the [[Caribbean]], and areas of the [[Pacific Ocean|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 the tropics, mostly in humid lowland subtropical climates, in highlands in southern Asia, and along the rim lands of the [[Mediterranean Sea]]. The northernmost native palm is ''[[Chamaerops|Chamaerops humilis]]'', which reaches [[44th parallel north|44°N latitude]] along the coast of [[Liguria]], [[Italy]].<ref>{{Cite journal |last1=Orsino |first1=Francesco |last2=Olivari |first2=Silvia |date=January 1, 1987 |title=The presence of Chamaerops humilis L. on Portofino promontory (East Liguria) |url=https://doi.org/10.1080/00837792.1987.10670414 |journal=Webbia |volume=41 |issue=2 |pages=261–272 |doi=10.1080/00837792.1987.10670414}}</ref> In the southern hemisphere, the southernmost palm is the ''[[Rhopalostylis sapida]]'' (nīkau), which reaches [[44th parallel south|44°S]] on the [[Chatham Islands]] where an [[oceanic climate]] prevails.<ref name="FAO">{{Cite web |title=Tropical Palms by Food and Agriculture Organization |url=http://www.fao.org/documents/show_cdr.asp?url_file=/docrep/X0451E/X0451e03.htm |url-status=dead |archive-url=https://web.archive.org/web/20060506005013/http://www.fao.org/documents/show_cdr.asp?url_file=%2Fdocrep%2FX0451E%2FX0451e03.htm |archive-date=May 6, 2006}}</ref> Cultivation of palms 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 [[microclimate]]s. In the [[United States]], there are at least 12 native palm species, mostly occurring in the states of the [[Deep South]] and [[Florida]].<ref>{{Cite web |title=Westcoast Landscape and Lawns &#124; Are Palm Trees Native to Florida? |url=https://westcoastlawns.com/florida-friendly/palm-trees-native-florida/}}</ref>

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 the [[canopy (biology)|canopy]] and shorter ones form part of the [[understory]].<ref name="VPEintro" /> 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 {{convert|1|e3m|e3ft|0|abbr=off}}, such as those in the genus ''[[Ceroxylon]]'' native to the [[Andes]]. Palms may also live in grasslands and scrublands, usually associated with a water source, and in desert [[oasis|oases]] such as the [[date palm]]. A few palms are adapted to extremely [[base (chemistry)|basic]] [[lime (mineral)|lime]] soils, while others are similarly adapted to extreme [[Potassium deficiency (plants)|potassium deficiency]] and toxicity of heavy metals in [[serpentine soil]]s.<ref name="FAO" />

==Taxonomy==

[[File:Roystonea-2.jpg|thumb|right|Two ''[[Roystonea regia]]'' specimens. The characteristic crownshaft and apex shoot, or 'spear', are visible.]]

Palms are a [[monophyly|monophyletic]] group of plants, meaning the group consists of a common ancestor and all its descendants.<ref name="VPEintro" /> Extensive taxonomic research on palms began with botanist [[Harold E. Moore|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, is a revision of Moore's classification that organizes palms into 6 subfamilies.<ref>N. W. Uhl, J. Dransfield (1987). ''Genera palmarum: a classification of palms based on the work of Harold E. Moore, Jr.'' (Allen Press, Lawrence, Kansas).</ref> A few general traits of each subfamily are listed below.
* Subfamily '''{{vanchor|Arecoideae|text=[[Arecoideae]]}}''' are the largest subfamily with [[List of Arecaceae genera#Subfamily Arecoideae|14 tribes]] and containing over 100 genera. All tribes have pinnate or bipinnate leaves and flowers arranged in groups of three, with a central pistillate and two staminate flowers.
* Subfamily '''{{vanchor|Calamoideae|text=[[Calamoideae]]}}''' includes the climbing palms, such as rattans. The leaves are usually pinnate; derived characters ([[synapomorphy|synapomorphies]]) include spines on various organs, organs specialized for climbing, an extension of the main stem of the leaf-bearing reflexed spines, and overlapping scales covering the fruit and ovary.
* Subfamily '''{{vanchor|Ceroxyloideae|text=[[Ceroxyloideae]]}}''' has small to medium-sized flowers, spirally arranged, with a [[gynoecium]] of three joined carpels.
* Subfamily '''{{vanchor|Coryphoideae|text=[[Coryphoideae]]}}''' are the second-largest subfamily with [[List of Arecaceae genera#Subfamily Coryphoideae|8 tribes]]. Most palms in this subfamily have palmately lobed leaves and solitary flowers with three, or sometimes four [[carpel]]s. The fruit normally develops from only one carpel.
* Subfamily '''{{vanchor|Nypoideae|text=[[Nypoideae]]}}''' contains only one species, ''[[Nypa fruticans]]'',<ref>{{Cite book |last=John Leslie Dowe |url=https://books.google.com/books?id=Fk5ud3uuLW8C&q=Nypoideae&pg=PA83 |title=Australian Palms: Biogeography, Ecology and Systematics |publisher=Csiro |year=2010 |isbn=9780643096158 |page=83 |access-date=April 20, 2012 |archive-url=https://web.archive.org/web/20140202163500/http://books.google.com.vn/books?id=Fk5ud3uuLW8C&pg=PA83&lpg=PA83&dq=Nypoideae&source=bl&ots=GLh89V2U04&sig=-rXN3kSbWv1-bOs8xgcDThEfC84&hl=vi&sa=X&ei=ekWRT4iCJ4TeigfavvSJBA&ved=0CDIQ6AEwAg#v=onepage&q=Nypoideae&f=false |archive-date=February 2, 2014 |url-status=live}}</ref> which has large, pinnate leaves. The fruit is unusual in that it floats, and the stem is underground and dichotomously branched, also unusual in palms.

The '''{{vanchor|Phytelephantoideae|text=[[Phytelepheae|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 the modern phylogenomic data, the Phytelephantoideae are tribe in the  [[Ceroxyloideae#Phytelepheae|Ceroxyloideae]] subfamily.<ref name="UA" />

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 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 marker]]s, and character polarization.<ref>{{Cite journal |last=Hahn |first=William J. |year=2002 |title=A Molecular Phylogenetic Study of the Palmae (Arecaceae) Based on ''atp''B, ''rbc''L, and 18S nrDNA Sequences |journal=Systematic Biology |volume=51 |issue=1 |pages=92–112 |doi=10.1080/106351502753475899 |jstor=3070898 |pmid=11943094 |doi-access=free}}</ref> 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 the chloroplast DNA. Chemical and molecular data from non-organelle DNA, for example, could be more effective for studying palm phylogeny.<ref name="UA">{{Cite web |title=Palms on the University of Arizona Campus |url=http://arboretum.arizona.edu/palms.htm |url-status=dead |archive-url=https://web.archive.org/web/20060621003136/http://arboretum.arizona.edu/palms.htm |archive-date=June 21, 2006}}</ref>

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, the [[Dasypogonaceae]].<ref>{{Cite journal |last1=Barrett |first1=C.

==Evolution==
{{more citations needed section|date=January 2016}}
The Arecaceae were the first modern family of monocots to appear in the fossil record around 80&nbsp;million years ago (Mya), during the late [[Cretaceous]] period. The first modern species, such as ''[[Nypa fruticans]]'' and ''[[Acrocomia aculeata]]'', appeared 69&nbsp;Mya, as evidenced by fossil ''Nypa'' pollen. Palms appear to have undergone an early period of [[adaptive radiation]]. By 60&nbsp;Mya, many of 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.

* Palm leaves are also valuable to some peoples as a material for thatching, basketry, clothing, and in religious ceremonies (see "Symbolism" below).<ref name="FAO" />
* Ornamental uses: Today, palms are valuable as [[ornamental plant]]s and are often grown along streets in [[tropical]] and [[subtropical]] cities. ''[[Chamaedorea elegans]]'' is a popular [[houseplant]] and is grown indoors for its low maintenance. Farther north, palms are a common feature in [[botanical gardens]] or as indoor plants. Few palms tolerate severe cold and the majority of the species are tropical or subtropical.

==Endangered species==
[[Image:Pritchardia affinis.jpg|thumb|right|''[[Pritchardia affinis]]'', a critically endangered species endemic to the [[Hawaiian Islands]]]]

Like many other plants, palms have been threatened by [[human impact on the environment|human intervention]] and [[exploitation of natural resources|exploitation]]. The greatest risk to palms is [[habitat destruction|destruction of habitat]], especially in the [[tropical forest]]s, due to [[urbanization]], [[Woodchipping|wood-chipping]], [[mining]], and [[conversion to farmland]]. Palms rarely reproduce after such great changes in 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]]).<ref name="KaheleHeartsHanaHou">{{Cite magazine |last=Rose Kahele |date=August–September 2007 |title=Big Island Hearts |url=http://www.hanahou.com/pages/Magazine.asp?Action=DrawArticle&ArticleID=591&MagazineID=38 |url-status=live |archive-url=https://web.archive.org/web/20160826100500/http://www.hanahou.com/pages/Magazine.asp?Action=DrawArticle&ArticleID=591&MagazineID=38 |archive-date=2016-08-26 |access-date=2016-08-14 |magazine=[[Hana Hou!]] |volume=10 |issue=4}}</ref> The use of [[rattan palm]]s in furniture has caused a major population decrease in these species that has negatively affected local and international markets, as well as biodiversity in the area.<ref>{{Cite book |url=http://intranet.iucn.org/webfiles/doc/SSC/SSCwebsite/Act_Plans/Executive_Summary_Palms_Action_Plan_EN.pdf |title=Palms: Their Conservation and Sustained Utilization |publisher=International Union for Conservation of Nature |year=1996 |isbn=978-2-8317-0352-7 |editor-last=Dennis Johnson |access-date=2009-07-02 |archive-url=https://web.archive.org/web/20090114055220/http://intranet.iucn.org/webfiles/doc/SSC/SSCwebsite/Act_Plans/Executive_Summary_Palms_Action_Plan_EN.pdf |archive-date=2009-01-14 |url-status=dead}}</ref> The sale of seeds to nurseries and collectors is another threat, as the seeds of popular palms are sometimes harvested directly from the wild. In 2006, at least 100 palm species were considered endangered, and nine species have been reported as recently extinct.<ref name="VPEintro" />

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 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.<ref name="VPEconserv" /> 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 the status of palms in the wild, use of wild palms, and palms under cultivation. Two projects on palm conservation and use supported by the [[WWF (conservation organization)|World Wildlife Fund]] took place from 1985 to 1990 and 1986–1991, in the American tropics and southeast Asia, respectively. Both studies produced copious new data and publications on palms. Preparation of a global action plan for palm conservation began in 1991, supported by the IUCN, and was published in 1996.<ref name="VPEconserv">{{Cite web |title=Palm Conservation: Its Atecedents, Status, and Needs |url=http://www.plantapalm.com/Vpe/conservation/vpe_conservation2.htm |url-status=dead |archive-url=https://web.archive.org/web/20060815153142/http://www.plantapalm.com/vpe/conservation/vpe_conservation2.htm |archive-date=August 15, 2006}}</ref>

==Symbolism==

{{Main|Palm branch (symbol)}}

[[File:Edward Hitchcock Paleontological Chart.jpg|thumb|upright=1.4|[[Edward Hitchcock]]'s fold-out paleontological chart in his 1840 ''Elementary Geology'', showing the Palms as the crown of the plant [[Tree of life (biology)|tree of life]], alongside Man as the crown of the animal tree of life.]]

The palm branch was a symbol of triumph and victory in [[classical antiquity]]. The [[Ancient Rome|Romans]] rewarded champions of the games and celebrated military successes with palm branches. 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 [[Lulav|Four Species]] of [[Sukkot]]; the palm may also symbolize the [[Tree of Life]] in [[Kabbalah]].

The canopies of the Rathayatra carts which carry the deities of Krishna and his family members in the cart festival of Jagganath Puri in India are marked with the emblem of a palm tree. Specifically it is the symbol of Krishna's brother, Baladeva.{{citation needed|date=January 2020}}

In 1840, the American geologist [[Edward Hitchcock]] (1793–1864) published the first tree-like paleontology chart in his ''Elementary Geology'', with two separate [[Tree of life (biology)|trees of life]] for the plants and the animals.
