Abstract
Limonium ophioides and L. nichoriense, two newly discovered species from south Peloponnisos (Greece) are described and illustrated based on their sole known populations at the Maleas Peninsula and Petalidi Messinias, respectively. Both species are diploid (2n=2x=18) and exhibit sexual breeding systems, featuring dimorphic pollen and stigmas alongside high pollen viability. Their karyological, reproductive, and morphological traits align them with the informal “L. cancellatum-dictyophorum” group, with L. coronense and L. pylium showing the closest morphological resemblance. Detailed observations on their morphological features, chromosomes, distribution, ecological preferences, conservation status, and an analytical key for all diploid Limonium species found in Peloponnisos are presented.
