Abstract:

The previous typification of Leontodon taraxacum L. (≡ Taraxacum officinale F.H. Wigg.) and hence of the generic name Taraxacum is analysed. It is shown that the typification and consequent nomenclatural and interpretation changes have been almost totally ignored by the botanical public and therefore have become a source of ambiguity or confusion, and that the previous lectotype is in serious conflict with the protologue. A new lectotype is designated that is in accordance with the protologue and corresponds to the currently generally adopted reasonably broad interpretation of Taraxacum officinale as a name of an aggregate of agamospermous and sexual common dandelions. The new lectotype is “Dens leonis latiore folio Bauh., In Lusatia, Bohemia, Dania,” J. Burser vi.37 (UPS). In order to retain the broad-sense interpretation of the name, the authors do not recommend subsequent epitypification of the name.
