The species-rich and widespread genus Taraxacum F. H. Wiggers, 1780 (Asteraceae subfamily Cichorioideae) is one of the most taxonomically complex plant genera in the world, mainly due to its combination of different sexual and asexual reproduction st

A study of the very complex, from the taxonomic point of view, Taraxacum genus was undertaken in the area between the towns of Cieszyn and Bielsko-Biała (S Poland). Taraxacum species belonging to three sections: sect. Hamata H. Øllg. (three species

Dandelions (genus Taraxacum) comprise a group of sexual diploids and apomictic polyploids with a complicated reticular evolution. Apomixis (clonal reproduction through seeds) in this genus is considered to be obligate, and therefore represent a good

The morphological variation and cytotype diversity were investigated among Central European populations traditionally recognized as Dactylorhiza fuchsii, recently incorporated in D. maculata s.l. Flow cytometry was employed to assess the ploidy level

Ploidy can serve as an excellent diagnostic character and proxy for evolutionary and reproductive behaviour, particularly in taxonomically complicated apomictic genera. In Rubus, ploidy level has so far been established for 230 European species (ca 3
