Magnolia is a large genus of about 210 [notes 1] flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol.

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Flowering plant clade of flowering plants (in APG I-III)

The flowering plants, also known as angiosperms, Angiospermae or Magnoliophyta, are the most diverse group of land plants, with 64 orders, 416 families, approximately 13,164 known genera and c. 369,000 known species. Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds. Etymologically, angiosperm means a plant that produces seeds within an enclosure; in other words, a fruiting plant. The term comes from the Greek words angeion and sperma ("seed").

In biology, a species ( ) is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species. Also, among organisms that reproduce only asexually, the concept of a reproductive species breaks down, and each clone is potentially a microspecies.

Contents

Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. [1] Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. [2] 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 ).

Bee clade of insects

Bees are flying insects closely related to wasps and ants, known for their role in pollination and, in the case of the best-known bee species, the western honey bee, for producing honey and beeswax. Bees are a monophyletic lineage within the superfamily Apoidea and are presently considered a clade, called Anthophila. There are over 16,000 known species of bees in seven recognized biological families. They are found on every continent except Antarctica, in every habitat on the planet that contains insect-pollinated flowering plants.

Pollination The cascade of biological processes occurring in plants beginning when the pollen lands on the female reproductive organs of a plant and continuing up to, but not including, fertilization, as defined by sperm-egg cell fusion.

Pollination is the transfer of pollen from a male part of a plant to a female part of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind. Pollinating agents are animals such as insects, birds, and bats; water; wind; and even plants themselves, when self-pollination occurs within a closed flower. Pollination often occurs within a species. When pollination occurs between species it can produce hybrid offspring in nature and in plant breeding work.

Beetle order of insects

Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. Their front pair of wings are hardened into wing-cases, elytra, distinguishing them from most other insects. The Coleoptera, with about 400,000 species, is the largest of all orders, constituting almost 40% of described insects and 25% of all known animal life-forms; new species are discovered frequently. The largest of all families, the Curculionidae (weevils) with some 70,000 member species, belongs to this order. Found in almost every habitat except the sea and the polar regions, they interact with their ecosystems in several ways: beetles often feed on plants and fungi, break down animal and plant debris, and eat other invertebrates. Some species are serious agricultural pests, such as the Colorado potato beetle, while others such as Coccinellidae eat aphids, scale insects, thrips, and other plant-sucking insects that damage crops.

The natural range of Magnolia species is a disjunct distribution, with a main center in east and southeast Asia and a secondary center in eastern North America, Central America, the West Indies, and some species in South America.

Disjunct distribution Ecology

In biology, a taxon with a disjunct distribution is one that has two or more groups that are related but considerably separated from each other geographically. The causes are varied and might demonstrate either the expansion or contraction of a species range.

Asia Earths largest and most populous continent, located primarily in the Eastern and Northern Hemispheres

Asia is Earth's largest and most populous continent, located primarily in the Eastern and Northern Hemispheres. It shares the continental landmass of Eurasia with the continent of Europe and the continental landmass of Afro-Eurasia with both Europe and Africa. Asia covers an area of 44,579,000 square kilometres (17,212,000 sq mi), about 30% of Earth's total land area and 8.7% of the Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilizations. Asia is notable for not only its overall large size and population, but also dense and large settlements, as well as vast barely populated regions. Its 4.5 billion people constitute roughly 60% of the world's population.

North America Continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere

North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere; it is also considered by some to be a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea.

As with all Magnoliaceae, the perianth is undifferentiated, with 9–15 tepals in 3 or more whorls. The flowers are bisexual with numerous adnate carpels and stamens are arranged in a spiral fashion on the elongated receptacle. The fruit dehisces along the dorsal sutures of the carpels. The pollen is monocolpate, and the embryo development is of the Polygonum type.

Magnoliaceae family of plants

The Magnoliaceae are a flowering plant family, the magnolia family, in the order Magnoliales. It consists of two subfamilies: Magnolioideae, of which Magnolia is the best-known genus, and Liriodendroidae, a monogeneric subfamily, of which Liriodendron is the only genus.

Perianth

The perianth is the non-reproductive part of the flower, and structure that forms an envelope surrounding the sexual organs, consisting of the calyx (sepals) and the corolla (petals). The term perianth is derived from the Greek περί, peri, meaning around, and άνθος, anthos, meaning flower, while perigonium is derived from gonos, meaning seed, i.e. sexual organs. In the mosses and liverworts (Marchantiophyta), the perianth is the sterile tubelike tissue that surrounds the female reproductive structure.

Whorl (botany)

In botany, a whorl or verticil is an arrangement of sepals, petals, leaves, stipules or branches that radiate from a single point and surround or wrap around the stem. A whorl consists of at least three elements; a pair of opposite leaves is not called a whorl.

History

Early

The name Magnolia first appeared in 1703 in the Genera [3] of Charles Plumier (1646–1704), for a flowering tree from the island of Martinique (talauma). 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 [4] and of Mark Catesby's Natural History of Carolina, Florida and the Bahama Islands. [5] 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 Lamarck, [6] and has since been named Magnolia plumieri and Talauma plumieri (and still a number of other names) but is now known as Magnolia dodecapetala. [notes 2]

Charles Plumier French botanist

Charles Plumier was a French botanist, after whom the Frangipani genus Plumeria is named. Plumier is considered one of the most important of the botanical explorers of his time. He made three botanizing expeditions to the West Indies, which resulted in a massive work Nova Plantarum Americanarum Genera (1703–04) and was appointed botanist to king Louis XIV of France.

Martinique Overseas region and department in France

Martinique is an insular region of France located in the Lesser Antilles of the West Indies in the eastern Caribbean Sea, with a land area of 1,128 square kilometres (436 sq mi) and a population of 376,480 inhabitants as of January 2016. Like Guadeloupe, it is an overseas region of France, consisting of a single overseas department. One of the Windward Islands, it is directly north of Saint Lucia, southeast of Greater Antilles, northwest of Barbados, and south of Dominica.

William Sherard was an English botanist. Next to John Ray, he was considered to be one of the outstanding English botanists of his day.

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 which was described by 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 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. [notes 3]

Carl Linnaeus Swedish botanist, physician, and zoologist

Carl Linnaeus, also known after his ennoblement as Carl von Linné, was a Swedish botanist, physician, and zoologist who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus.

<i>Systema Naturae</i> major work by Carolus Linnaeus

Systema Naturae is one of the major works of the Swedish botanist, zoologist and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard and Johann, 200 years earlier, Linnaeus was first to use it consistently throughout his book. The first edition was published in 1735. The full title of the 10th edition (1758), which was the most important one, was Systema naturæ per regna tria naturæ, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis or translated: "System of nature through the three kingdoms of nature, according to classes, orders, genera and species, with characters, differences, synonyms, places".

<i>Species Plantarum</i> book by Carl Linnæus

Species Plantarum is a book by Carl Linnaeus, originally published in 1753, which lists every species of plant known at the time, classified into genera. It is the first work to consistently apply binomial names and was the starting point for the naming of plants.

By the end of the 18th century, botanists and plant hunters exploring Asia began to name and describe the Magnolia species from China and Japan. The first Asiatic species to be described by western botanists were Magnolia denudata and Magnolia liliiflora , [notes 4] and Magnolia coco and Magnolia figo . [notes 5] Soon after that, in 1794, Carl Peter Thunberg collected and described Magnolia obovata from Japan and at roughly the same time Magnolia kobus was also first collected. [7]

Recent

With the number of species increasing, the genus was divided into the 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 colour in many new hybrids.

Relations in the family Magnoliaceae have been puzzling 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. [notes 6]

Phylogenetic era

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. [8] [9] [10] What these studies all revealed was that 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. [11]

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 genus Magnolia into 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 for 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 even is 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.

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, 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. [12] The western co-author favors the big genus Magnolia, whereas the Chinese recognize the different small genera.

Subdivision

Species of Magnolia are most commonly listed under three subgenera, 12 sections, and 13 subsections, such as that used here, following the classification of the Magnolia Society. [13] It does not represent the last word on the subclassification of the genus Magnolia (see above), as a clear consensus has not yet been reached. Each species entry follows this pattern: Botanical nameNaming auth. - (REGION FOUND)

The subdivision structure is as follows:

Horticultural uses

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).

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 size of their leaves.

Culinary uses

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. 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 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. [22] [23]

In parts of Japan, the leaves of M. obovata are used for wrapping food and as cooking dishes.

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.

Timber

The cucumbertree, M. acuminata, grows to large size and is harvested as a timber tree in northeastern US 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.

Other uses

Magnolias are used as food plants by the larvae of some Lepidoptera species, including the giant leopard moth.

Chemical compounds and bioeffects

The aromatic bark contains magnolol, honokiol, 4-O-methylhonokiol, and obovatol. [24] [25] [26] [27] [28] [29] Magnolol [30] and honokiol [31] activate the nuclear receptor peroxisome proliferator-activated receptor gamma.

  • The 1989 movie Steel Magnolias is based on a 1987 play, Steel Magnolias , by Robert Harling.
  • 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 referenced 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 image which inspired his poem, Lawrence Beitler's 1930 photograph capturing the lynching of Thomas Shipp and Abram Smith following the robbery and murder of Claude Deteer, actually occurred 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."

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. Often treated as a distinct species, Magnolia pyramidata.
  8. Often treated as a distinct species, Magnolia ashei.
  9. Often treated as a distinct species, Magnolia dealbata.

There are usually between three and twelve leaves arranged in two ranks on each pseudobulb or shoot and lasting for several years. From one to a large number of flowers are arranged on an unbranched flowering stem arising from the base of the pseudobulb. The sepals and petals are all free from and similar to each other. The labellum is significantly different from the other petals and the sepals and has three lobes. There are about fifty five species and sixteen further natural hybrids occurring in the wild from tropical and subtropical Asia to Australia.
