Knautia drymeja Heuff. subsp. centrifrons (Borbás) Ehrend. – Note: Recently, K. drymeja was regarded as a morphologically and genetically variable species
without infraspecific taxa, also including K. gussonei (Rešetnik et al. 2016). The authors based their morphometric analyses on single specimens for 43 populations
of the complex. Only a single voucher specimen of K. gussonei was studied. Furtermore, some characters useful for identification in morphometric
analyses (i.e., presence of glandular hairs, see Bartolucci and Conti 2014) were not considered at all. Waiting for further studies, we are provisionally maintaining
here the taxonomic treatment proposed by Conti et al. (2005).
