Moreover, <i>S.mutabilis</i> (which has been considered conspecific with <i>S.neglecta</i>) and <i>S.martinolii</i> (an alleged endemic species to south-western Sardinia) are considered here as taxonomic synonyms of <i>S.nocturna</i> and <i>S.neglecta</i>, respectively. These taxonomic conclusions are strongly supported by multivariate morphometric analyses of 21 characters.PhytoKeys143-160https://www.ebi.ac.uk/biostudies/studies/S-EPMC9848993biostudies-literatureRe-establishment of <i>Sileneneglecta</i> Ten.
