discovered a misapplication of the name Echinacea purpurea (L.) Moench for the taxon correctly named Echinacea serotina (Nutt.) DC. Just two decades later, De Candolle raised him to the rank of species of the other genus Echinacea serotina (Nutt.) DC. In 1818, Thomas Nuttall describes a new variety that he named Rudbeckia purpurea var. Originally named Rudbeckia purpurea by Linnaeus in 1753 in Species plantarum 6, it was reclassified in 1794 by Conrad Moench, in a new genus named Echinacea purpurea (L.) Moench. The epithet purpurea means 'reddish-purple'.
Echinacea is derived from Greek, meaning 'spiny one', in reference to the spiny sea urchins 'εχίνοι' which the ripe flower heads of species of this genus resemble.
