'''Magnoliídeas''' (ou [[Magnoliidae]] ou [[Magnolianae]]; em inglês: [[magnoliids]], plural, não capitalizado) é a designação usada pelo [[APG]], a partir do [[sistema APG II]] (2003), para designar um [[clado]] de [[plantas com flor]] que inclui a maioria dos [[Basal|grupos basais]] das angiospérmicas. Tratado geralmente ao [[nível taxonómico]] de subclasse, agrupa mais de 10&nbsp;000 espécies, incluindo a [[magnólia]], a [[noz-moscada]], o [[louro]], a [[canela]], o [[abacate]], a [[pimenta preta]], a [[tulipa]] e muitas outras plantas com importância económica e ambiental, sendo o terceiro maior grupo de angiospérmicas depois das [[eudicotiledóneas]] e das [[monocotiledóneas]].<ref>{{cite journal | pmc=8724549 | year=2021 | last1=Wu | first1=J.

O nome '''magnoliídeas''' (em inglês: '''magnoliids''' - plural, não capitalizado) é usado pelo [[sistema APG II]] (2003) para um [[clado]] dentro das [[angiosperma]]s. O circunscrição é a seguinte:
==Descrição==

A [[circunscrição taxonómica]] do agrupamento é a seguinte:
* clado '''magnoliídeas''' ('''magnoliids''') :
* clado '''magnoliídeas''' ('''magnoliids''') :
*: ordem [[Canellales]]
**: ordem [[Canellales]]
*: ordem [[Laurales]]
**: ordem [[Laurales]]
*: ordem [[Magnoliales]]
**: ordem [[Magnoliales]]
*: ordem [[Piperales]]
**: ordem [[Piperales]]

O clado inclui a maioria dos grupos basais de angiospérmicas.

As plantas pertencentes a este clado são basicamente as mesmas que eram colocadas na subclasse [[Magnoliidae]], no [[sistema de Cronquist]], que é o [[grupo basal]] da classe [[Magnoliopsida]] (o nome do sistema de Cronquist para as dicotiledóneas).
<!-----------------------

==Classification==
"Magnoliidae" is the [[botanical name]] of a [[subclass (biology)|subclass]], and "magnoliids" is an informal name that does not conform to the [[International Code of Nomenclature for algae, fungi, and plants]]. The [[wikt:circumscription|circumscription]] of a subclass will vary with the [[List of systems of plant taxonomy|taxonomic system]] being used. The only requirement is that it must include the family [[Magnoliaceae]].<ref>[[International Code of Nomenclature for algae, fungi, and plants]], Art. 16</ref> The informal name "magnoliids" is used by some researchers to avoid the confusion that recently surrounds the name "Magnoliidae." More recently,{{clarify|more recently? Since 2009?|date=February 2016}} the group{{clarify|under what name, is there a name?|date=February 2016}} has been redefined under the ''PhyloCode'' as a node-based [[clade]] comprising the [[Canellales]], [[Laurales]], [[Magnoliales]], and [[Piperales]].{{citation needed|date=February 2016}} Chase & Reveal have proposed "Magnoliidae" as the name used for the entire group of flowering plants, and the formal name "Magnolianae" for the group of four orders discussed here.<ref name=C&R>{{citation |author1=Chase, M.W. |author-link1=Mark Wayne Chase |author2=Reveal, J.L. |author-link2=James Reveal |year=2009 |title=A phylogenetic classification of the land plants to accompany APG III |journal=Botanical Journal of the Linnean Society |volume=161 |issue=2 |pages=122–127 |doi=10.1111/j.1095-8339.2009.01002.x|doi-access=free }}</ref>

===APG system===
The [[APG III system|APG III]] (2009) and its predecessor systems did not originally use formal botanical names above the [[rank (botany)|rank]] of order. Under those systems, larger clades were usually referred to by informal names, such as "magnoliids" (plural, not capitalized) or "magnoliid complex". The formal name in [[Linnean nomenclature]] was specified in a separate APG publication as the existing name "Magnolianae" [[Armen Takhtajan|Takht.]] (1967).<ref name=C&R/> The APG III recognizes a [[clade]] within the [[angiosperms]] for the magnoliids. The circumscription is:

The clade includes most of the basal groups of the angiosperms. This clade was formally named Magnoliidae in 2007 under provisions of the ''[[PhyloCode]]''.<ref name="Cantino">{{cite journal | last= Cantino | first= Philip D. |author2=James A.

===Cronquist system===
[[File:Magnolia obovata 02.jpg|thumb|right|240px|Flower of ''[[Magnolia obovata]]'', showing multiple [[petal]]s, [[stamen]]s, and [[pistil]]s.]]
The [[Cronquist system]] (1981) used the name Magnoliidae for one of six subclasses (within class [[Magnoliopsida]] = [[dicotyledons]]). In the original version of this system the circumscription was:<ref name="Cronquist">{{cite book | last=Cronquist | first=Arthur | year=1981 | title=An Integrated System of Classification of Flowering Plants | url=https://archive.org/details/integratedsystem0000cron | location=New York | publisher=Columbia University Press | isbn=0-231-03880-1 }}</ref>
* Subclass Magnoliidae :
*: Order [[Aristolochiales]]
*: Order [[Illiciales]]
*: Order [[Laurales]]
*: Order [[Magnoliales]]
*: Order [[Nymphaeales]]
*: Order [[Papaverales]]
*: Order [[Piperales]]
*: Order [[Ranunculales]]

===Dahlgren and Thorne systems===
Both [[Dahlgren system|Dahlgren]] and [[Thorne system (1992)|Thorne]] classified the magnoliids (''sensu'' APG) in superorder '''Magnolianae''', rather than as a subclass.<ref name="Thorne 1992"/> In their systems, the name Magnoliidae is used for a much larger group including all [[dicotyledons]]. This is also the case in some of the systems derived from the Cronquist system.

Dahlgren divided his Magnolianae into ten [[order (biology)|orders]], more than other systems of the time, and unlike Cronquist and Thorne, he did not include the [[Piperales]].<ref name="Dahlgren"/> Thorne grouped most of his Magnolianae into two large orders, [[Magnoliales]] and [[Berberidales]], although his Magnoliales was divided into suborders along lines similar to the ordinal groupings used by both Cronquist and Dahlgren. Thorne revised his system in 2000, restricting the name Magnoliidae to include only the Magnolianae, Nymphaeanae, and Rafflesianae, and removing the Berberidales and other previously included groups to his subclass Ranunculidae.<ref name="Thorne 2000"/> This revised system diverges from the Cronquist system, but agrees more closely with the circumscription later published under APG II.

===Comparison table===
Comparison of classification systems is often difficult. Two authors may apply the same name to groups with different composition of members; for example, Dahlgren's Magnoliidae includes all [[dicot]]s, whereas Cronquists' Magnoliidae is only one of five dicot groups. Two authors may also describe the same group with nearly identical composition, but each may then apply a different name to that group or place the group at a different [[taxonomic rank]]. For example, the composition of Cronquist's ''subclass'' Magnoliidae is nearly the same as Thorne's (1992) ''superorder'' Magnolianae, despite the difference in taxonomic rank.

Because of these difficulties and others, the synoptic table below imprecisely compares the definition of "magnoliid" groups in the systems of four authors. For each system, only orders are named in the table. All orders included by a particular author are listed and linked in that column. When a taxon is not included by that author, but was included by an author in another column, that item appears in unlinked italics and indicates remote placement. The sequence of each system has been altered from its publication in order to pair corresponding taxa between columns.

==Economic uses==
The magnoliids is a large group of plants, with many species that are economically important as food, drugs, perfumes, timber, and as ornamentals, among many other uses.

[[File:Persea americana 2.jpg|thumb|right|The [[avocado]] has been cultivated in the Americas for thousands of years.]]
One widely cultivated magnoliid [[fruit]] is the [[avocado]] (''Persea americana''), which is believed to have been cultivated in [[Mexico]] and [[Central America]] for nearly 10,000 years.<ref name="EB">{{cite encyclopedia | title = Angiosperms | encyclopedia = The New Encyclopædia Britannica | volume = 13 | pages = 634–645 | year = 1994 }}</ref> Now grown throughout the tropics, it probably originates from the [[Chiapas]] region of Mexico or [[Guatemala]], where "wild" avocados may still be found.<ref>{{cite journal | last=Kopp | first=Lucille E. | year=1966 | title=A taxonomic revision of the genus ''Persea'' in the Western Hemisphere. (''Persea''-Lauraceae) | journal=Memoirs of the New York Botanical Garden | volume=14 | issue=1 | pages=1–117 }}</ref> The soft pulp of the fruit is eaten fresh or mashed into [[guacamole]]. The ancient peoples of Central America were also the first to cultivate several fruit-bearing species of ''[[Annona]]''.<ref name="Cronquist"/> These include the [[custard-apple]] (''A. reticulata''), [[soursop]] (''A. muricata''), sweetsop or [[sugar-apple]] (''A. squamosa''), and the [[cherimoya]] (''A. cherimola''). Both soursop and sweetsop now are widely grown for their fruits in the Old World as well.<ref name="Heywood">{{cite book | editor-last=Heywood | editor-first=V.

Some members of the magnoliids have served as important food additives, such as [[black pepper]], [[nutmeg]], [[bay laurel]] and [[cinnamon]]. Oil of [[sassafras]] was formerly used as a key flavoring in both [[root beer]] and in [[Sarsaparilla (soft drink)|sarsaparilla]].<ref>{{cite book | last=Hester |author2=Roy M. Harrison | year=2001 | title=Food safety and food quality | publisher=Royal Society of Chemistry | isbn=0-85404-270-9 |pages=118|first=R. E. }}</ref> The primary ingredient responsible for the oil's flavor is [[safrole]], but it is no longer used in either the [[United States]] or [[Canada]]. Both nations banned the use of safrole as a food additive in 1960 as a result of studies that demonstrated safrole promoted [[liver]] damage and [[tumor]]s in mice.<ref name="Hayes">{{cite book | last=Hayes | first=Andrew Wallace | year=2001 | title= Principles and Methods of Toxicology | edition=4th | publisher=CRC Press | isbn=1-56032-814-2 | pages=518 }}</ref> Consumption of more than a minute quantity of the oil causes [[nausea]], vomiting, hallucinations, and shallow rapid breathing.

[[File:Myris fragr Fr 080112-3294 ltn.jpg|thumb|left|[[Nutmeg]] fruits are a source of the [[hallucinogen]] [[myristicin]].]]
Other magnoliids also are known for their narcotic, hallucinogenic, or paralytic properties. The [[Polynesian culture|Polynesian]] beverage [[kava]] is prepared from the pulverized roots of ''Piper methysticum'', and has both sedative and [[narcotic]] properties.<ref name="Heywood"/> It is used throughout the Pacific in social gatherings or after work to relax.

Not all the effects of chemical compounds in the magnoliids are detrimental. In previous centuries, sailors would use Winter's Bark from the [[South America]]n tree ''[[Drimys winteri]]'' to ward off the vitamin-deficiency of [[scurvy]].<ref name="Heywood"/> Today, [[benzoyl]] is extracted from ''[[Lindera benzoin]]'' (common spicebush) for use as a food additive and skin medicine, due to its anti-bacterial and anti-fungal properties.<ref>{{cite book | last=Zomlefer | first=Wendy B. | year=1994 | title= Guide to Flowering Plant Families | location=Chapel Hill | publisher=University of North Carolina Press | isbn=0-8078-2160-8 | pages=29–39 }}</ref> Drugs extracted from the bark of ''[[Magnolia]]'' have long been used in traditional Chinese medicine.

Many magnoliid species produce [[essential oil]]s in their leaves, bark, or wood.

Magnoliídeas (ou Magnoliidae ou Magnolianae; em inglês: magnoliids, plural, não capitalizado) é a designação usada pelo APG, a partir do sistema APG II (2003), para designar um clado de plantas com flor que inclui a maioria dos grupos basais das angiospérmicas. Tratado geralmente ao nível taxonómico de subclasse, agrupa mais de 10 000 espécies, incluindo a magnólia, a noz-moscada, o louro, a canela, o abacate, a pimenta preta, a tulipa e muitas outras plantas com importância económica e ambiental, sendo o terceiro maior grupo de angiospérmicas depois das eudicotiledóneas e das monocotiledóneas.[3] O grupo é caracterizado por flores trímeras, grãos de pólen com um poro e folhas com venação geralmente ramificada. Alguns membros da subclasse estão entre as primeiras angiospérmicas e partilham semelhanças anatómicas com as gimnospérmicas, com estames que se assemelham às escamas do cone masculino das coníferas e os carpelos que se encontram ao longo eixo de floração.[4]

Descrição

A circunscrição taxonómica do agrupamento é a seguinte:

O clado inclui a maioria dos grupos basais de angiospérmicas.

As plantas pertencentes a este clado são basicamente as mesmas que eram colocadas na subclasse Magnoliidae, no sistema de Cronquist, que é o grupo basal da classe Magnoliopsida (o nome do sistema de Cronquist para as dicotiledóneas).
