A molecular phylogeny of the mainly South African genus Gorteria is presented for the first time, based on Bayesian inference and parsimony analyses using DNA sequences from plastid trnL ‐ F and from nuclear ETS and ITS regions. It is shown that the genus is strongly paraphyletic in relation to one subgroup of Hirpicium , a finding that changes the prevailing generic concept and circumscription of Gorteria and Hirpicium . Furthermore, Gorteria diffusa and G. personata both seem to be polyphyletic assemblages, comprised of some more or less well diagnosed monophyletic groups with different distributions.
