33-590: Magnoliidae is a botanical subclass name; it may refer to: Magnoliids , a major group of basal angiosperms. Magnoliidae sensu Chase & Reveal , a botanical subclass consisting of all angiosperms. In the Dahlgren and Thorne systems, a group consisting of the Dicotyledons (Class Magnoliopsida in the Cronquist system) [REDACTED] Topics referred to by

66-475: A group of chemicals called acetogenins . The first acetogenin discovered was uvaricin , which has anti- leukemic properties when used in living organisms. Other acetogenins have been discovered with anti- malarial and anti-tumor properties, and some even inhibit HIV replication in laboratory studies. Many magnoliid species produce essential oils in their leaves, bark, or wood. The tree Virola surinamensis (Brazilian "nutmeg") contains trimyristin , which

99-512: A minute quantity of the oil causes nausea , vomiting, hallucinations, and shallow rapid breathing. It is very toxic, and can severely damage the kidneys. In addition to its former use as a food additive, safrole from either Sassafras or Ocotea cymbarum is also the primary precursor for synthesis of MDMA ( methylenedioxymethamphetamine ), commonly known as the drug ecstasy. Other magnoliids also are known for their narcotic, hallucinogenic, or paralytic properties. The Polynesian beverage kava

132-490: 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. 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. One widely cultivated magnoliid fruit

165-463: Is also the case in some of the systems derived from the Cronquist system. Dahlgren divided his Magnolianae into ten orders , more than other systems of the time, and unlike Cronquist and Thorne, he did not include the Piperales . Thorne grouped most of his Magnolianae into two large orders, Magnoliales and Berberidales , although his Magnoliales was divided into suborders along lines similar to

198-409: Is different from Wikidata All article disambiguation pages All disambiguation pages Magnoliids Canellales Laurales Magnoliales Piperales Magnoliids , Magnoliidae or Magnolianae are a clade of flowering plants . With more than 10,000 species, including magnolias , nutmeg , bay laurel , cinnamon , avocado , black pepper , tulip tree and many others, it

231-399: Is extracted in the form of a fat and used in soaps and candles , as well as in shortenings . Other fragrant volatile oils are extracted from Aniba rosaeodora ( bois-de-rose oil ), Cinnamomum porrectum , Cinnamomum cassia , and Litsea odorifera for scenting soaps. Perfumes also are made from some of these oils; ylang-ylang comes from the flowers of Cananga odorata , and

264-429: Is often difficult. Two authors may apply the same name to groups with different composition of members; for example, Dahlgren's Magnoliidae includes all dicots , 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,

297-515: Is prepared from the pulverized roots of Piper methysticum , and has both sedative and narcotic properties. It is used throughout the Pacific in social gatherings or after work to relax. Likewise, some native peoples of the Amazon take a hallucinogenic snuff made from the dried and powdered fluid exuded from the bark of Virola trees. Another hallucinogenic compound, myristicin , comes from

330-529: Is that it must include the family Magnoliaceae . The informal name "magnoliids" is used by some researchers to avoid the confusion that recently surrounds the name "Magnoliidae." More recently, the group has been redefined under the PhyloCode as a node-based clade comprising the Canellales , Laurales , Magnoliales , and Piperales . Chase & Reveal have proposed "Magnoliidae" as the name used for

363-517: Is the avocado ( Persea americana ), which is believed to have been cultivated in Mexico and Central America for nearly 10,000 years. Now grown throughout the tropics, it probably originates from the Chiapas region of Mexico or Guatemala , where "wild" avocados may still be found. The soft pulp of the fruit is eaten fresh or mashed into guacamole . The ancient peoples of Central America were also

396-468: Is the third-largest group of angiosperms after the eudicots and monocots . The group is characterized by trimerous flowers, pollen with one pore, and usually branching-veined leaves. Some members of the subclass are among the earliest angiosperms and share anatomical similarities with gymnosperms like stamens that resemble the male cone scales of conifers and carpels found on the long flowering axis. According to molecular clock calculations,

429-588: Is used by Arab and Swahili women. A compound called nutmeg butter is produced from the same tree as the spice of that name, but the sweet-smelling "butter" is used in perfumery or as a lubricant rather than as a food. APG III system Along with the publication outlining the new system, there were two accompanying publications in the same issue of the Botanical Journal of the Linnean Society : The APG III system recognized all of

462-506: The PhyloCode . 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: Both Dahlgren and Thorne classified the magnoliids ( sensu APG) in superorder Magnolianae , rather than as a subclass. In their systems, the name Magnoliidae is used for a much larger group including all dicotyledons . This

495-481: The 45 orders of the previous system, as well as 14 new ones. The order Ceratophyllales was erroneously marked as a new order, as it had been recognized in both of the previous APG systems . The newly recognized orders were: The designation of alternative "bracketed families" was abandoned in APG III, because its inclusion in the previous system had been unpopular. APG III recognized 413 families , 43 fewer than in

528-542: The APG system ( APG system , APG II system ). Further detail on relationships can be seen in the phylogenetic tree below. Legend: * = new family placement; † = newly recognized order for the APG system; § = new family circumscription described in the text; $ = families that represent the broader circumscription of options available in APG II and favoured here; $ $ = families that were in square brackets in APG II,

561-400: The bark of Magnolia have long been used in traditional Chinese medicine. Scientific investigation of magnolol and honokiol have shown promise for their use in dental health. Both compounds demonstrate effective anti-bacterial activity against the bacteria responsible for bad breath and dental caries . Several members of the family Annonaceae are also under investigation for uses of

594-458: 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

627-549: The compound as a poison to tip their arrows in hunting. Not all the effects of chemical compounds in the magnoliids are detrimental. In previous centuries, sailors would use Winter's Bark from the South American tree Drimys winteri to ward off the vitamin-deficiency of scurvy . 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. Drugs extracted from

660-486: The entire group of flowering plants, and the formal name "Magnolianae" for the group of four orders discussed here. The APG III (2009) and its predecessor systems did not originally use formal botanical names above the 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

693-1247: The families in the text of the paper that established APG III. ORDERS: Amborellales (1), Nymphaeales (3), Austrobaileyales (3), Chloranthales (1), Canellales (2), Piperales (5), Magnoliales (6), Laurales (7), Acorales (1), Alismatales (13), Petrosaviales (1), Dioscoreales (3), Pandanales (5), Liliales (10), Asparagales (14), Arecales (1), Poales (16), Commelinales (5), Zingiberales (8), Ceratophyllales (1), Ranunculales (7), Proteales (3), Trochodendrales (1), Buxales (2), Gunnerales (2), Saxifragales (14), Vitales (1), Zygophyllales (2), Celastrales (2), Oxalidales (7), Malpighiales (35), Fabales (4), Rosales (9), Fagales (7), Cucurbitales (7), Geraniales (3), Myrtales (9), Crossosomatales (7), Picramniales (1), Sapindales (9), Huerteales (3), Brassicales (17), Malvales (10), Berberidopsidales (2), Santalales (7), Caryophyllales (34), Cornales (6), Ericales (22), Garryales (2), Gentianales (5), Solanales (5), Lamiales (23), Aquifoliales (5), Asterales (11), Escalloniales (1), Bruniales (2), Apiales (7), Paracryphiales (1), Dipsacales (2).

726-500: The family Icacinaceae remains especially doubtful. Apodytes and its close relative, Rhaphiostylis , as well as Emmotum , Cassinopsis , and a few other genera were provisionally retained within it until further studies can determine whether they properly belong there. Three genera ( Gumillea , Nicobariodendron , and Petenaea ) were placed within the angiosperms incertae sedis. Gumillea had been unplaced in APG II . Nicobariodendron and Petenaea were newly added to

759-532: The first to cultivate several fruit-bearing species of Annona . 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. Some members of the magnoliids have served as important food additives, such as black pepper , nutmeg , bay laurel and cinnamon . Oil of sassafras

792-490: The lineage that led to magnoliids split from other plants about 135 million years ago or 160-165 million years ago. "Magnoliidae" is the botanical name of a subclass , and "magnoliids" is an informal name that does not conform to the International Code of Nomenclature for algae, fungi, and plants . The circumscription of a subclass will vary with the taxonomic system being used. The only requirement

825-435: The list. The latter was later placed into its own family Petenaeaceae in the order Huerteales The classification is shown below in two versions. The short version goes to the level of orders and of families unplaced in an order. The detailed version shows all the families. Orders at the same level in the classification are arranged alphabetically. Note that orders may not contain the same families as in earlier versions of

858-618: The narrower circumscriptions favoured here. The APG III system was based on a phylogenetic tree for the angiosperms which included all of the 59 orders and 4 of the unplaced families. The systematic positions of the other 6 unplaced families was so uncertain that they could not be placed in any of the polytomies in the tree. They are shown in the classification table entitled "Detailed version" above, 4 in Euasterids I and 2 in Taxa of uncertain position. The phylogenetic tree shown below

891-584: 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. This revised system diverges from the Cronquist system, but agrees more closely with the circumscription later published under APG II. Comparison of classification systems

924-448: The previous system. Forty-four of the 55 "bracketed families" were discontinued, and 20 other families were discontinued as well. The discontinued bracketed families were: The other discontinued families were: 21 families were accepted in the APG III system which had not been in the previous system, and a few families were moved to a different position. The newly recognized families are: The number of families not placed in any order

990-538: The spice nutmeg. As with safrole, ingestion of nutmeg in quantities can lead to hallucinations, nausea, and vomiting, with symptoms lasting several days. A more severe reaction comes from poisoning by rodiasine and demethylrodiasine , the active ingredients in fruit extract from Chlorocardium venenosum . These chemicals paralyze muscles and nerves, resulting in tetanus -like reactions in animals. The Cofán peoples of westernmost Amazon in Colombia and Ecuador use

1023-467: Was formerly used as a key flavoring in both root beer and in sarsaparilla . 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 tumors in mice. Consumption of more than

1056-502: Was reduced from 39 to 10. Apodanthaceae and Cynomoriaceae were placed among the angiosperms , incertae sedis , that is, not in any group within the angiosperms. Eight other families were placed incertae sedis in various supra-ordinal groups within the angiosperms. The families not placed in any order were: The paragraph below shows the number of families in each order and the placement of those families that were not included in any order. These figures were produced by simply counting

1089-456: Was specified in a separate APG publication as the existing name "Magnolianae" Takht. (1967). The APG III recognizes a clade within the angiosperms for the magnoliids. The circumscription is: Chloranthales Canellales Piperales Laurales Magnoliales monocots Ceratophyllales eudicots The clade includes most of the basal groups of the angiosperms. This clade was formally named Magnoliidae in 2007 under provisions of
