Eponymy
In 1703 Charles Plumier (1646-1704) gave a flowering tree from the island of Martinique the genus name Magnolia, after Magnol. The name was later adopted by Linnaeus in the first edition of Species plantarum, with a reference to Plumier's name. This way, Magnolia became the name of the large genus of ornamental flowering trees as we know it to date. See Origin of the name Magnolia.
