Alexis Jordan

Jordanism

In 1845, it integrates the Société linnéenne of Lyon and begins in entomology in company of Antoine Casimir Marguerite Eugene Foudras (1783 - 1859). It côtoya founders of the Company linnéenne of Lyon, in particular Clemence Lortet (1772 - 1835), Jean Right Christmas Antoine Aunier (1781? - 1859), Jean-Baptiste Balbis (1765 - 1831), Georges Roffavier (1775 - 1866), Nicolas Charles Seringe (1776 - 1858) and Marc Antoine Timeroy (1793 - 1856). This last studies the species thoroughly and thus discovers new forms in the region of Lion which it announces to Alexis Jordan. These critical species interests the Jordan young person who notes the characters carefully and compares them with those of individuals of other stations. He thus recognizes many typified forms, formerly considered as simple varieties, deserving in his eyes the statute of species. Its new method known as analytical is at the origin of a true “Jordanian School” which led its followers to describe species more and more by taking account of increasingly thin differences, while checking in experiments that these species were not hybridaient between them. As example, Alexis Jordan recognized, with his collaborator Pierre Jules Fourreau (1844 - 1871), some 200 species of Erophila ; what will not fail to poke the most severe criticisms. Its method was largely taken again by the malacologist Arnould Locard (1841 - 1904) for the continental molluscs, which same manner caused strong reactions. The species S of Alexis Jordan, with the number of approximately 1685, were called jordanies by Georges Coutagne (1854 - 1928) and Jordanon by Johannes Paulus Lotsy (1867 - 1931).

Its herbarium is considerable and was one of largest of Europe in its time. During 40 years, from 1836 with 1877, it traversed France (especially the Alps and Provence) and accepted exsiccata of almost 200 botanists among whom appeared Eugene Bourgeau (1813-1877) (of 1845 with 1875), Elisee Reverchon (of 1866 with 1897), Benedict Balansa (1825-1892) (of 1852 with 1867) and Theodor Heinrich Hermann von Heldreich (1822-1902) (of 1848 with 1892).

Goatskin bottles its collections of dried plants, it gathered a vast collection of alive plants within an experimental garden under the responsibility of his/her faithful collaborator, chief of cultures, Joseph Victor Viviand-Morel (1843-1915), also horticultural editor association of Lyon . Alexis Jordan cultivated with the assistance of his chief of cultures, the thousands of plant species during 50 years in order to attest in an experimental way that the close species that it cultivated did not hybridaient between them and thus could be regarded as distinct species.
