title: New nomenclatural combinations for taxa of Pentanema (Asteraceae) occurring in Ukraine
abstract: Recent molecular phylogenetic results demonstrated that the genus Inula in its traditional circumscription is polyphyletic and its type, I. helenium, belongs to a clade phylogenetically distant from the clade containing the majority of species earlier placed in Inula. The nomenclatural proposal to conserve the generic name Inula with I. hirta as the conserved type has not been adopted. Because of that the genus Inula s. str. now comprises ca. 5 species (I. helenium and its relatives). The genus
