Based on morphology, distribution, habitat data and ambiguous sites in the nrITS sequences, T. farellonicum is supposed to be a hybridogenic species, originating from a cross between T. gilliesii of T. sect Antarctica, the only known Taraxacum species in South America with a sexual mode of reproduction, and an introduced species probably of T. sect. Taraxacum, and fixed by an agamospermous mode of reproduction (Uhlemann & al. 2009).
