Pierre Magnol (8 June 1638 – 21 May 1715) was a French botanist. He was born in the city of Montpellier, then in the province of Languedoc, where he lived and worked for most of his life. He became Professor of Botany and Director of the Royal Botanic Garden of Montpellier and held a seat in the Académie Royale des Sciences de Paris for a short while. He was one of the innovators who devised the botanical scheme of classification. He was the first to publish the concept of plant families as they are understood today, a natural classification of groups of plants that have features in common.

Pierre Magnol in the context of Taxon
In biology, the taxon (back-formation from taxonomy; pl.: taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based ("Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping.
Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle and, later still, European scientists, like Magnol, Tournefort and Carl Linnaeus's system in Systema Naturae, 10th edition (1758),, as well as an unpublished work by Bernard and Antoine Laurent de Jussieu, contributed to this field. The idea of a unit-based system of biological classification was first made widely available in 1805 in the introduction to Jean-Baptiste Lamarck's Flore françoise, and Augustin Pyramus de Candolle's Principes élémentaires de botanique. Lamarck set out a system for the "natural classification" of plants. Since then, systematists continue to construct accurate classifications encompassing the diversity of life; today, a "good" or "useful" taxon is commonly taken to be one that reflects evolutionary relationships.
Pierre Magnol in the context of Magnolia
Magnolia is a large genus of about 210 to 340 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.
Magnolias are evergreen or deciduous trees or shrubs known for their large, fragrant, bowl- or star-shaped flowers with numerous spirally arranged reproductive parts, producing cone-like fruits in autumn that open to reveal seeds. The genus Magnolia was first named in 1703 by Charles Plumier, honoring Pierre Magnol, with early taxonomy refined by Linnaeus in the 18th century based on American and later Asian species. Modern molecular phylogenetic studies have revealed complex relationships leading to taxonomic debates about merging related genera like Michelia with Magnolia. Magnolia species are valued horticulturally for their early and showy flowering, used culinarily in various edible forms, employed in traditional medicine for their bioactive compounds like magnolol and honokiol, and harvested for timber, with hybridization enhancing desirable traits.
