Аннотация:Drastic recircumscription of Pentanema (Asteraceae) resulted in transfers of many species from Inula, whereas hybrids with binomials did not receive new combinations yet. However, names for interspecific hybrids of Inula auct. are in active current use, and a dozen of nothospecies are being regularly mentioned in floras, checklists, and research papers. I facilitate 12 new combinations for nothospecies in Pentanema: P. ×adriaticum (Borbás) Seregin (P. hirtum × P. spiraeifolium), P. ×haussmannii (Huter) Seregin (P. ensifolium × P. hirtum), P. ×hispidum (Schur) Seregin (P. asperum × P. hirtum), P. ×hybridum (Baumg.) Seregin (P. ensifolium × P. germanicum), P. ×litorale (Borbás) Seregin (P. ensifolium × P. spiraeifolium), P. ×mucheri (Starm.) Seregin (P. salicinum × P. squarrosum), P. ×savii (Beck) Seregin (P. salicinum × P. spiraeifolium), P. ×semiamplexicaule (Reut.) Seregin (P. helveticum × P. salicinum), P. ×strictum (Tausch) Seregin (P. ensifolium × P. salicinum), P. ×suaveolens (Jacq.) Seregin (P. oculus-christi × P. squarrosum), P. ×transsilvanicum (Schur) Seregin (P. asperum × P. germanicum), P. ×vrabelyianum (Kern.) Seregin (P. asperum × P. ensifolium). A lectotype is designated for Inula ×hausmannii Huter instead of superseded neotype published in 2019. Examples of current use are given for every hybrid. Availability of the new names will certainly be helpful for wider use and acceptance of Pentanema.
