Abstract
Modes of evolution of species classified within different sections inTaraxacum involve diverse processes, viz. primary divergence of an ancestral sexual diploid, hybridization between a tetraploid apomict and a diploid sexual hybrid, differentiation of an advanced apomictic taxon at one ploidy level, hybridization between a sexual tetraploid and a sexual diploid, formation of a polyploid series from an apomictic ancestor of a lower polyploidy level, and remote hybridization between an autumn-flowering ancestral diploid and a spring-flowering derivative diploid or apomict. Various reproduction systems of the plants involved, different environments and different timing of the processes contribute to a very varied nature of the species groups.
