Abstract

The nomenclature and typification of the sections in the genus Taraxacum Wigg. are discussed. The genus is typified by a specimen of Leontodon taraxacum from Linnaeus' Flora Lapponica for which the modern synonym is T. campylodes Hagl. This becomes the type of T. officinale Weber, and T. sect. Crocea M. P. Christiansen to which T. campylodes was assigned becomes a synonym of T. sect. Taraxacum. It is considered that the sections and subsections published by Handel-Mazzetti (1907) are validated in the table of contents in that work. The problems resulting from the earlier use of species in two different rank concepts in this largely agamospermous genus are highlighted, as are early incorrect citations, and recent transgressions of the ICBN. The sections of the genus are listed in full, with type species and synonymy. Two new sections are described, T. sect. Borea Sahlin and T. sect. Celtica Richards and Sahlin.
