Augustin Pyrame de Candolleborn February 4,Geneva—died September 9,GenevaSwiss botanist who established scientific structural criteria for determining natural relations among plant genera.

Augustin Pyramus de Candolle

His system of plant classification found nearly universal application for half a century, during which time it served as a model for other systems. When he was appointed professor of botany at the University of MontpellierCandolle had already begun a government-commissioned botanical and agricultural survey of France —12the results of which he published in After introducing the concept of homologous parts of common ancestry, although different in structure for plants as Cuvier had done for animals—particularly convincing evidence in favour of organic evolution—Candolle, like Cuvier, nonetheless retained a firm belief in the constancy of species.

He next undertook the most ambitious task of preparing a descriptive classification of all known seed plants, Prodromus Systematis Naturalis Regni Vegetabilis 17 vol. Although his taxonomy suffered from a failure to observe his own criteria in formulating broad taxa, resulting in his inclusion of gymnosperms with dicotyledons, ferns with monocotyledons, and all else as acotyledons, Candolle achieved extensive subdivision of flowering plants, cadolle families of dicotyledons, and demonstrated decisively the inadequacy of Linnaean classification, which his system supplanted.
