TARAXACUM

The type of the genus, Taraxacum officinale, is conserved. This name is linked to the (very general) description of Leontodon taraxacum Linnaeus. A. J. Richards (1985) typified T. officinale, via L. taraxacum, on a specimen that is apparently referable to T. campylodes Haglund, a microspecies of sect. Crocea restricted to Lapland, which thus became the basis of sect. Taraxacum. J. Kirschner and J. Štepánek (1987) underlined that this typification of T. officinale does not reflect usage of the name, which raises considerable ambiguity as to its application, because Richards essentially defined a new content for it. The species usually referred to as T. officinale must now be referred to sect. Ruderalia (Kirschner and Štepánek); no name was proposed that would correspond closely with the species currently called T. officinale. A proposal to conserve the name T. officinale with a neotype that would preserve its common usage for this widespread entity has been suggested; this has yet to be discussed fully.
