Reviewing forgotten “Pre‐Linnaean” generic names validly published in the third volume of Diderot and d'Alembert's Encyclopédie in 1753

This paper presents a comprehensive review of previously overlooked names published in the third volume of the Encyclopédie by Diderot and d'Alembert in 1753. These names primarily originate from Tournefort's pre‐Linnaean work, including textual copies of Tournefort's descriptions. We identified 21 names as having been validly published. Notably, among these are five generic names (Castanea, Chamaemelum, Chrysanthemoides, Citreum, Cydonia) wherein the taxonomic authorship shifts from Miller to Daubenton according to priority. Consequently, by our typifications, Miller's names from 1754 are later isonyms. Additionally, the generic name Chamaebuxus takes priority over Polygaloides. As a result, we propose a new combination, Chamaebuxus paucifolia and designate types for 31 generic names and isonyms: Caprifolium, Castanea, Chamaebuxus, Chamaecerasus, Chamaemelum, Chamaerhododendros, Chrysanthemoides, Cichorium, Cicuta, Cicutaria, Clandestina, Clymenum, Colocynthis, Citreum, Clematitis, Coa, Comaroides, Cydonia, Gramen, Scorpioides, and Sisarum, and lectotypes for two species names: Chamaebuxus paucifolia and Polygala uniflora.
