The name ''Magnolia'' first appeared in 1703 in the ''[[Genera]]''<ref name=Plumier>Plumier, C. (1703) ''Nova plantarum Americanarum genera''. Paris. [New genera of American plants].</ref> written by [[French people|French]] botanist [[Charles Plumier]] (1646–1704), for a flowering tree from the island of [[Martinique]] (''talauma''). It was named after the French botanist [[Pierre Magnol]]. The English botanist [[William Sherard]], who studied botany in Paris under [[Joseph Pitton de Tournefort]], a pupil of [[Magnol]], was most probably the first after Plumier to adopt the genus name ''Magnolia''. He was at least responsible for the [[Taxonomy (biology)|taxonomic]] part of [[Johann Jacob Dillenius]]'s ''Hortus Elthamensis''<ref>Dillenius, J.J. (1732), ''Hortus Elthamensis, seu plantarum rariorum quas in horto suo Elthami in Cantio coluit vir ornamentissimus et praestantissimus Jacobus Sherard''.

(1730), ''The Natural History of Carolina, Florida and the Bahama Islands, containing the figures of birds, beasts, fishes, serpents, insects and plants, Vol. 1.'' London.</ref> These were the first works after Plumier's ''Genera'' that used the name ''Magnolia'', this time for some species of [[flowering plant|flowering trees]] from [[temperate]] North America. The species that Plumier originally named ''Magnolia'' was later described as ''[[Annona dodecapetala]]'' by [[Lamarck]],<ref>Lamarck, J.B.P.A. de (1786), ''Encyclopédie Méthodique Botanique'', tome second: 127. Paris.</ref> and has since been named ''Magnolia plumieri'' and ''Talauma plumieri'' (among a number of other names), but is now known as ''Magnolia dodecapetala''.<ref group=lower-alpha>Under the rule of priority, the first name that is validly published in Linnaeus' ''Species Plantarum'' (1 May 1753) or any other work of any other [[botanist]] after that, takes precedence over later names. Plumier's name was not a [[binomen]] and moreover published before ''Species Plantarum'', so it has no status. The first binomen published after 1753 was Lamarck's ''Annona dodecapetala'' (1786). ''Magnolia plumieri'' (1788) was published on a later date by Schwartz, and is treated as a later synonym, as are ''Magnolia fatiscens'' (1817; Richard), ''Talauma caerulea'' (Jaume St-Hilaire 1805) and ''Magnolia linguifolia'' (1822).</ref>

[[Carl Linnaeus]], who was familiar with Plumier's ''Genera'', adopted the genus name ''Magnolia'' in 1735 in his first edition of ''[[Systema Naturae]]'', without a description but with a reference to Plumier's work. In 1753, he took up Plumier's ''Magnolia'' in the first edition of ''[[Species Plantarum]]''. There he described a [[monotypic]] genus, with the sole species being ''[[Magnolia virginiana]]''. Since Linnaeus never saw a herbarium specimen (if there ever was one) of Plumier's ''Magnolia'' and had only his description and a rather poor picture at hand, he must have taken it for the same plant that was described by Catesby in his 1730 ''Natural History of Carolina''. He placed it in the [[synonym (taxonomy)|synonymy]] of ''Magnolia virginiana'' var. ''fœtida'', the [[taxon]] now known as ''[[Magnolia grandiflora]]''. Under ''Magnolia virginiana'', Linnaeus described five varieties (''glauca'', ''fœtida'', ''grisea'', ''tripetala'', and ''acuminata''). In the tenth edition of ''Systema Naturae'' (1759), he merged ''grisea'' with ''glauca'' and raised the four remaining varieties to species status.<ref group=lower-alpha>''Magnolia glauca'' has the same type specimen as ''Magnolia virginiana'' and as the latter is the first valid name, the species is now called ''Magnolia virginiana'' (sweetbay magnolia). Var. ''fœtida'' was renamed ''[[Magnolia grandiflora]]'', which is legitimate as the epithet ''fœtida'' only has priority in its rank of variety. ''Magnolia grandiflora'' is the southern magnolia. ''[[Magnolia tripetala]]'' (umbrella magnolia) and ''[[Magnolia acuminata]]'' (cucumber tree) are still recognized as species.</ref>

By the end of the 18th century, botanists and plant hunters exploring Asia had begun to name and describe the ''Magnolia'' species from China and Japan. The first Asiatic species to be described by western botanists were ''[[Magnolia denudata]]'', ''[[Magnolia liliiflora]]'',<ref group=lower-alpha>Under these names the species were described by [[Louis Auguste Joseph Desrousseaux|Desrousseaux]] in [[Lamarck]]'s ''Encyclopédie Méthodique Botanique'', tome troisieme (1792): 675. In the beginning of the 20th century, descriptions which seemed to represent the same species, were found in a work of the French naturalist [[Pierre Joseph Buchoz|P.J. Buc'hoz]], ''Plantes nouvellement découvertes'' (1779), under the names ''Lassonia heptapeta'' and ''Lassonia quinquepeta''. In 1934, the English botanist J.E. Dandy argued that these names had priority over the names by which both species had been known for over a century and hence from then on ''Magnolia denudata'' had to be named ''Magnolia heptapeta'', ''Magnolia liliiflora'' should be changed into ''Magnolia quinquepeta''. After a lengthy debate, specialist taxonomists decided that the Buc'hoz's names were based on [[chimaeras]] (pictures constructed of elements of different species), and as Buc'hoz did not cite or preserve herbarium specimens, his names were ruled not to be acceptable.</ref> ''[[Magnolia coco]],'' and ''[[Michelia figo|Magnolia figo]]''.<ref group=lower-alpha>These species were published as ''Liriodendron coco'' and ''Liriodendron figo'' by J. de Loureiro in ''Flora Cochinchinensis'' (1790) and later (1817) transferred to ''Magnolia'' by [[A.

''Magnolia figo'' was soon after transferred to the genus ''Michelia''.</ref> Soon after that, in 1794, [[Carl Peter Thunberg]] collected and described ''Magnolia obovata'' from Japan, and roughly at the same time, ''[[Magnolia kobus]]'' was also first collected.<ref>''Magnolia kobus'' only received its name in 1814, when it was validly published by A.P. de Candolle.

''Magnolia'' contains the American evergreen species ''M. grandiflora'', which is of [[horticulture|horticultural]] importance, especially in the southeastern [[United States]], and ''M. virginiana'', the type species. ''Yulania'' contains several [[deciduous]] Asiatic species, such as ''M. denudata'' and ''M. kobus'', which have become horticulturally important in their own right and as parents in hybrids. Classified in ''Yulania'' is also the American deciduous ''M. acuminata'' (cucumber tree), which has recently attained greater status as the parent responsible for the yellow flower color in many new hybrids.{{cn|date=June 2024}}

Relations in the family Magnoliaceae have puzzled taxonomists for a long time. Because the family is quite old and has survived many geological events (such as ice ages, mountain formation, and continental drift), its distribution has become scattered. Some species or groups of species have been isolated for a long time, while others could stay in close contact. To create divisions in the family (or even within the genus ''Magnolia'') solely based upon morphological characters has proven to be a nearly impossible task.<ref group=lower-alpha>In 1927 J.E. Dandy accepted 10 genera in ''The genera of Magnoliaceae'', ''Kew Bulletin 1927'': 257–264. In 1984 Law Yuh-Wu proposed 15 in ''A preliminary study on the taxonomy of the family Magnoliaceae'', ''Acta Phytotaxonomica Sinica'' 22: 89–109; in 2004 even 16, in ''Magnolias of China''. This is not just about grouping some genera together where others do not; authors often choose different boundaries.</ref>

Not many ''Michelia'' species have so far become horticulturally or economically important, apart from their wood. Both subgenus ''Magnolia'' and subgenus ''Yulania'' include species of major horticultural importance, and a change of name would be very undesirable for many people, especially in the horticultural branch. In Europe, ''Magnolia'' is even more or less a synonym for ''Yulania'', since most of the cultivated species on this continent have ''Magnolia (Yulania) denudata'' as one of their parents. Most taxonomists who acknowledge close relations between ''Yulania'' and ''Michelia'' therefore support the third option and join ''Michelia'' with ''Magnolia''.{{cn|date=June 2024}}

The same goes, ''mutatis mutandis'', for the (former) genera ''[[Talauma]]'' and ''Dugandiodendron'', which are then placed in subgenus ''Magnolia'', and genus ''[[Manglietia]]'', which could be joined with subgenus ''Magnolia'' or may even earn the status of an extra subgenus. ''[[Elmerrillia]]'' seems to be closely related to ''Michelia'' and ''Yulania'', in which case it will most likely be treated in the same way as ''Michelia'' is now. The precise nomenclatural status of small or monospecific genera like ''Kmeria'', ''Parakmeria'', ''Pachylarnax'', ''Manglietiastrum'', ''Aromadendron'', ''Woonyoungia'', ''Alcimandra'', ''Paramichelia'', and ''Tsoongiodendron'' remains uncertain. Taxonomists who merge ''Michelia'' into ''Magnolia'' tend to merge these small genera into ''Magnolia'' s.l. as well. Botanists do not yet agree on whether to recognize a big ''Magnolia'' or the different small genera. For example, ''Flora of China'' offers two choices: a large genus ''Magnolia'', which includes about 300 species and everything in the [[Magnoliaceae]] except ''[[Liriodendron]]'' (tulip tree), or 16 different genera, some of them recently split out or re-recognized, each of which contains up to 50 species.<ref name="china">[http://efloras.org/florataxon.aspx?flora_id=2&taxon_id=10530 4.

[[Hybrid (biology)|Hybridisation]] has been immensely successful in combining the best aspects of different species to give plants which flower at an earlier age than the parent species, as well as having more impressive flowers. One of the most popular garden magnolias, ''M''. × ''soulangeana'', is a hybrid of ''M. liliiflora'' and ''M. denudata''.

In the eastern United States, five native species are frequently in cultivation: ''M. acuminata'' (as a shade tree), ''M. grandiflora'', ''M. virginiana'', ''M. tripetala'', and ''M. macrophylla''. The last two species must be planted where high winds are not a frequent problem because of the large size of their leaves.

The flowers of many species are considered edible. In parts of England, the petals of ''M. grandiflora'' are pickled and used as a spicy [[condiment]]{{citation needed|date=August 2024}}. In some Asian cuisines, the buds are pickled and used to flavor rice and scent tea. In Japan, the young leaves and flower buds of ''[[Magnolia hypoleuca|M. hypoleuca]]'' are broiled and eaten as a vegetable. Older leaves are made into a powder and used as seasoning; dried, whole leaves are placed on a charcoal brazier and filled with [[miso]], leeks, [[daikon]], and [[shiitake]], and broiled.

Magnolia is a large genus of about 210 to 340[a] flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. The natural range of Magnolia species is disjunct, with a main center in east, south and southeast Asia and a secondary center in eastern North America, Central America, the West Indies, and some species in South America.

Magnolia is an ancient genus. Fossilized specimens of M. acuminata have been found dating to 20 million years ago (mya), and fossils of plants identifiably belonging to the Magnoliaceae date to 95 mya.[2] They are theorized to have evolved to encourage pollination by beetles as they existed prior to the evolution of bees.[3] Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage, such as Amborella and Nymphaea (as well as with many more recently derived plants, such as Lilium).

The magnolia was made the state flower of Mississippi in 1900. The magnolia symbolizes stability in the United States; in China beauty and gentleness.

Magnolia seeds and fruit

Magnolias are spreading evergreen or deciduous trees or shrubs characterised by large fragrant flowers, which may be bowl-shaped or star-shaped, in shades of white, pink, purple, green, or yellow. In deciduous species, the blooms often appear before the leaves in spring. Cone-like fruits are often produced in the autumn.[4]

As with all Magnoliaceae, the perianth is undifferentiated, with 9–15 tepals in three or more whorls. The flowers are hermaphroditic, with numerous adnate carpels and stamens arranged in a spiral fashion on the elongated receptacle. The flowers' carpels are often damaged by pollinating beetles.[5]

The fruit dehisces along the dorsal sutures of the carpels. The pollen is monocolpate, and the embryonic development is of the Polygonum type.[citation needed] Taxonomists, including James E. Dandy in 1927, have used differences in the fruits of Magnoliaceae as the basis for classification systems.[6]

History

Early

Magnolia grandiflora

Flower bud

The name Magnolia first appeared in 1703 in the Genera[7] written by French botanist Charles Plumier, for a flowering tree from the island of Martinique (talauma). It was named after French botanist Pierre Magnol. English botanist William Sherard, who studied botany in Paris under Joseph Pitton de Tournefort, a pupil of Magnol, was most probably the first after Plumier to adopt the genus name Magnolia. He was at least responsible for the taxonomic part of Johann Jacob Dillenius's Hortus Elthamensis[8] and of Mark Catesby's Natural History of Carolina, Florida and the Bahama Islands.[9] These were the first works after Plumier's Genera that used the name Magnolia, this time for some species of flowering trees from temperate North America. The species that Plumier originally named Magnolia was later described as Annona dodecapetala by Jean-Baptiste Lamarck[10] and has since been named Magnolia plumieri and Talauma plumieri (among a number of other names), but is now known as Magnolia dodecapetala.[b]

Carl Linnaeus, who was familiar with Plumier's Genera, adopted the genus name Magnolia in 1735 in his first edition of Systema Naturae, without a description but with a reference to Plumier's work. In 1753, he took up Plumier's Magnolia in the first edition of Species Plantarum. There he describes a monotypic genus, with the sole species being Magnolia virginiana. Since Linnaeus never saw a herbarium specimen (if there ever was one) of Plumier's Magnolia and had only his description and a rather poor picture at hand, he must have taken it for the same plant that was described by Mark Catesby in his 1730 Natural History of Carolina. He placed it in the synonymy of Magnolia virginiana var. fœtida, the taxon now known as Magnolia grandiflora. Under Magnolia virginiana, Linnaeus describes five varieties (glauca, fœtida, grisea, tripetala, and acuminata). In the tenth edition of Systema Naturae (1759), he merges grisea with glauca and raises the four remaining varieties to species status.[c]

By the end of the 18th century, botanists and plant hunters exploring Asia had begun to name and describe the Magnolia species from China and Japan. The first Asiatic species to be described by western botanists were Magnolia denudata, Magnolia liliiflora,[d] Magnolia coco, and Magnolia figo.[e] Soon after that, in 1794, Carl Peter Thunberg collected and described Magnolia obovata from Japan, and roughly at the same time Magnolia kobus was also first collected.[11]

Recent

With the number of species increasing, the genus was divided into two subgenera, Magnolia and Yulania. Magnolia contains the American evergreen species M. grandiflora, which is of horticultural importance, especially in the southeastern United States, and M. virginiana, the type species. Yulania contains several deciduous Asiatic species, such as M. denudata and M. kobus, which have become horticulturally important in their own right and as parents in hybrids. Classified in Yulania is also the American deciduous M. acuminata (cucumber tree), which has recently attained greater status as the parent responsible for the yellow flower color in many new hybrids.[citation needed]

Relations in the family Magnoliaceae have puzzled taxonomists for a long time. Because the family is quite old and has survived many geological events (such as ice ages, mountain formation, and continental drift), its distribution has become scattered. Some species or groups of species have been isolated for a long time, while others could stay in close contact. To create divisions in the family (or even within the genus Magnolia) solely based upon morphological characters has proven to be a nearly impossible task.[f]

By the end of the 20th century, DNA sequencing had become available as a method of large-scale research on phylogenetic relationships. Several studies, including studies on many species in the family Magnoliaceae, were carried out to investigate relationships.[12][13][14] What these studies all revealed was that the genus Michelia and Magnolia subgenus Yulania were far more closely allied to each other than either one of them was to Magnolia subgenus Magnolia. These phylogenetic studies were supported by morphological data.[15]

As nomenclature is supposed to reflect relationships, the situation with the species names in Michelia and Magnolia subgenus Yulania was undesirable. Taxonomically, three choices are available:

  1. to join Michelia and Yulania species in a common genus, not being Magnolia (for which the name Michelia has priority);
  2. to raise subgenus Yulania to generic rank, leaving Michelia names and subgenus Magnolia names untouched, or;
  3. to join Michelia with the genus Magnolia into the genus Magnolia s.l. (a big genus).

Magnolia subgenus Magnolia cannot be renamed because it contains M. virginiana, the type species of the genus and of the family.

Not many Michelia species have so far become horticulturally or economically important, apart from their wood. Both subgenus Magnolia and subgenus Yulania include species of major horticultural importance, and a change of name would be very undesirable for many people, especially in the horticultural branch. In Europe, Magnolia is even more or less a synonym for Yulania, since most of the cultivated species on this continent have Magnolia (Yulania) denudata as one of their parents. Most taxonomists who acknowledge close relations between Yulania and Michelia therefore support the third option and join Michelia with Magnolia.[citation needed]

The same goes, mutatis mutandis, for the (former) genera Talauma and Dugandiodendron, which are then placed in subgenus Magnolia, and genus Manglietia, which could be joined with subgenus Magnolia or may even earn the status of an extra subgenus. Elmerrillia seems to be closely related to Michelia and Yulania, in which case it will most likely be treated in the same way as Michelia is now. The precise nomenclatural status of small or monospecific genera like Kmeria, Parakmeria, Pachylarnax, Manglietiastrum, Aromadendron, Woonyoungia, Alcimandra, Paramichelia, and Tsoongiodendron remains uncertain. Taxonomists who merge Michelia into Magnolia tend to merge these small genera into Magnolia s.l. as well. Botanists do not agree on whether to recognize a big Magnolia or the different small genera. For example, Flora of China offers two choices: a large genus Magnolia, which includes about 300 species and everything in the Magnoliaceae except Liriodendron (tulip tree), or 16 different genera, some of them recently split out or re-recognized, each of which contains up to 50 species.[16] The western co-author favors the big genus Magnolia, whereas the Chinese recognize the different small genera.

Fossil record

Fossils assignable to Magnolia extend into the Paleogene, such as Magnolia nanningensis, named for mummified wood from the Oligocene of Guangxi, China, which has a close affinity to members of the modern section Michelia.[17]

Subdivision

In 2012, the Magnolia Society published on its website a classification of the genus produced by Richard B. Figlar, based on a 2004 classification by Figlar and Hans Peter Nooteboom. Species of Magnolia were listed under three subgenera, 12 sections, and 13 subsections.[18][19] Subsequent molecular phylogenetic studies have led to some revisions of this system; for example, the subgenus Magnolia was found not to be monophyletic. A revised classification in 2020, based on a phylogenetic analysis of complete chloroplast genomes, abandoned subgenera and subsections, dividing Magnolia into 15 sections. The relationships among these sections are shown in the following cladogram, as is the paraphyletic status of subgenus Magnolia.[20]

Horticulture

In general, the genus Magnolia has attracted horticultural interest. Some, such as the shrub M. stellata (star magnolia) and the tree M. × soulangeana (saucer magnolia) flower quite early in the spring, before the leaves open. Others flower in late spring or early summer, including M. virginiana (sweetbay magnolia) and M. grandiflora (southern magnolia). The shape of these flowers lend themselves to the common name tulip tree that is sometimes applied to some Magnolia species.[g]

Hybridisation has been immensely successful in combining the best aspects of different species to give plants which flower at an earlier age than the parent species, as well as having more impressive flowers. One of the most popular garden magnolias, M. × soulangeana, is a hybrid of M. liliiflora and M. denudata. In the eastern United States, five native species are frequently in cultivation: M. acuminata (as a shade tree), M. grandiflora, M. virginiana, M. tripetala, and M. macrophylla. The last two species must be planted where high winds are not a frequent problem because of the large size of their leaves.

Culinary

The flowers of many species are considered edible. In parts of England, the petals of M. grandiflora are pickled and used as a spicy condiment[citation needed]. In some Asian cuisines, the buds are pickled and used to flavor rice and scent tea. In Japan, the young leaves and flower buds of M. hypoleuca are broiled and eaten as a vegetable. Older leaves are made into a powder and used as seasoning; dried, whole leaves are placed on a charcoal brazier and filled with miso, leeks, daikon, and shiitake, and broiled. There is a type of miso which is seasoned with magnolia, hoba miso.[26][27]

Traditional medicine

The bark and flower buds of M. officinalis have long been used in traditional Chinese medicine, where they are known as hou po (厚朴). In Japan, kōboku, M. obovata, has been used in a similar manner.[28][29]

Timber

The cucumbertree, M. acuminata, grows to large size and is harvested as a timber tree in northeastern U.S. forests. Its wood is sold as "yellow poplar" along with that of the tuliptree, Liriodendron tulipifera. The Fraser magnolia, M. fraseri, also attains enough size sometimes to be harvested, as well.[citation needed]

Chemical compounds and bioeffects

The aromatic bark contains magnolol, honokiol, 4-O-methylhonokiol, and obovatol.[30][31][32][33][34][35] Magnolol[36] and honokiol[37] activate the nuclear receptor peroxisome proliferator-activated receptor gamma.

Culture

Symbols

Arts

  • The 1989 movie Steel Magnolias is based on a 1987 play, Steel Magnolias, by Robert Harling. They are about the bond among a group of women from Louisiana, who can be as beautiful as magnolias, but are as tough as steel. The name 'magnolia' specifically refers to a magnolia tree about which they are arguing at the beginning.[38]
  • In the 1939 song "Strange Fruit", originally written as a poem by New York schoolteacher and communist activist Abel Meeropol to condemn the practice of lynching, the magnolia flower was referred to as being associated with the Southern United States, where many lynchings took place:
Pastoral scene of the gallant south
The bulging eyes and the twisted mouth
Scent of magnolias, sweet and fresh,
Then the sudden smell of burning flesh.

Despite Meeropol's frequent mention of the South and magnolia trees, the horrific image which inspired his poem, Lawrence Beitler's 1930 photograph of the lynching of Thomas Shipp and Abram Smith following the robbery and murder of Claude Deteer, was taken in Marion, Indiana, where magnolia trees are less common.

  • In the 1960s, magnolias were a symbol of the South in the popular press: the New York Post noted of Lyndon Johnson that "A man who wore a ten-gallon Stetson and spoke with a magnolia accent had little hope of winning the Democratic nomination in 1960", and biographer Robert Caro picks up the symbol by saying that when Johnson became president "[t]he taint of magnolias still remained to be scrubbed off."[39]

Notes

  1. ^ The number of species in the genus Magnolia depends on the taxonomic view that one takes up. Recent molecular and morphological research shows that former genera Talauma, Dugandiodendron, Manglietia, Michelia, Elmerrillia, Kmeria, Parakmeria, Pachylarnax (and a small number of monospecific genera) all belong within the same genus, Magnolia s.l. (s.l. = sensu lato: 'in a broad sense', as opposed to s.s. = sensu stricto: 'in a narrow sense'). The genus Magnolia s.s. contains about 120 species. See the section Nomenclature and classification in this article.
  2. ^ Under the rule of priority, the first name that is validly published in Linnaeus' Species Plantarum (1 May 1753) or any other work of any other botanist after that, takes precedence over later names. Plumier's name was not a binomen and moreover published before Species Plantarum, so it has no status. The first binomen published after 1753 was Lamarck's Annona dodecapetala (1786). Magnolia plumieri (1788) was published on a later date by Schwartz, and is treated as a later synonym, as are Magnolia fatiscens (1817; Richard), Talauma caerulea (Jaume St-Hilaire 1805) and Magnolia linguifolia (1822).
  3. ^ Magnolia glauca has the same type specimen as Magnolia virginiana and as the latter is the first valid name, the species is now called Magnolia virginiana (sweetbay magnolia). Var. fœtida was renamed Magnolia grandiflora, which is legitimate as the epithet fœtida only has priority in its rank of variety. Magnolia grandiflora is the southern magnolia. Magnolia tripetala (umbrella magnolia) and Magnolia acuminata (cucumber tree) are still recognized as species.
  4. ^ Under these names the species were described by Desrousseaux in Lamarck's Encyclopédie Méthodique Botanique, tome troisieme (1792): 675. In the beginning of the 20th century, descriptions which seemed to represent the same species, were found in a work of the French naturalist P.J. Buc'hoz, Plantes nouvellement découvertes (1779), under the names Lassonia heptapeta and Lassonia quinquepeta. In 1934, the English botanist J.E. Dandy argued that these names had priority over the names by which both species had been known for over a century and hence from then on Magnolia denudata had to be named Magnolia heptapeta, Magnolia liliiflora should be changed into Magnolia quinquepeta. After a lengthy debate, specialist taxonomists decided that the Buc'hoz's names were based on chimaeras (pictures constructed of elements of different species), and as Buc'hoz did not cite or preserve herbarium specimens, his names were ruled not to be acceptable.
  5. ^ These species were published as Liriodendron coco and Liriodendron figo by J. de Loureiro in Flora Cochinchinensis (1790) and later (1817) transferred to Magnolia by A. P. de Candolle. Magnolia figo was soon after transferred to the genus Michelia.
  6. ^ In 1927 J.E. Dandy accepted 10 genera in The genera of Magnoliaceae, Kew Bulletin 1927: 257–264. In 1984 Law Yuh-Wu proposed 15 in A preliminary study on the taxonomy of the family Magnoliaceae, Acta Phytotaxonomica Sinica 22: 89–109; in 2004 even 16, in Magnolias of China. This is not just about grouping some genera together where others do not; authors often choose different boundaries.
  7. ^ "Tulip tree" usually refers to Liriodendron tulipifera, but sometimes refers to Magnolia species,[21][22] especially Magnolia × soulangeana.[23][24][25]
