International audience. Since its first valid description by Linnaeus in 1753, the genus Delphinium L. has undergone numerous taxonomical changes that we synthesize here. The knowledge of the taxonomic history of the genus is essential to clarify its circumscription. For this purpose, we outline its pre-Linnaean taxonomic history, from Dioscorides’ translated works dating back to the 16th century to Tournefort’s classificationin 1694. Regarding its post-Linnaean history, we discuss the three different lectotypifications proposed during in the 20th century. In addition, we amend the description of the typical flower of Delphinium by including the characteristics of the species D. ecalcaratum S.Y. Wang & K.F. Zhou and D. turcicum (H.Duman, Vural, Aytaç & Adigüzel) Espinosa with actinomorphic flowers. . Depuis la première description valide du genre Delphinium L. en 1753 par Linné, celui-ci a subi de nombreuses modifications taxonomiques, dont la synthèse est proposée ici. Une connaissance de l’histoire taxonomique du genre est essentielle pour sa définition actuelle. Pour cela, d’une part, nous détaillons son histoire pré-linnéenne, depuis les traductions de Dioscoride datant du xvie siècle jusqu’à la classification de Tournefort en 1694. Nous présentons ensuite un historique de la taxonomie postlinnéenne du genre, en discutant les trois lectotypifications proposées au cours du xxe siècle. Nous exposons enfin sa taxonomie actuelle. D’autre part, nous amendons la description de sa fleur typique en y incluant les caractéristiques des espèces à fleurs actinomorphes D. ecalcaratum S.Y. Wang & K.F. Zhou et D. turcicum (H.Duman, Vural, Aytaç & Adigüzel) Espinosa.
