Anew species of Epipactis from the Madonie massif (Sicily), E. cupaniana C. Brullo, D’Emerico and Pulv. sp. nov., isdescribed and illustrated. It is a nemoral species, occurring in Holm oak woods, and is characterized by a diploid chromosomecomplement of 2n 2x 38. In the metaphase I, the mother cells of the embryo sac contain 19 bivalents. Withrespect to morphology and karyotype structure, the new species shows a close relationships with E. helleborine and otherallied species, such as E. meridionalis and E. schubertiorum, both occurring in southern Italy and Sicily. However, severalmorphological features, chromosome size, and differences in the heterochromatin distribution allow for a clear distinctionbetween E. cupaniana and the above-mentioned species.
