Table S12. Checklist of the phylum Magnoliophyta and comments to the checklist

This list is based in the previous knowledge on seagrass distribution (e.g. Phillips & Meñez 1988; Green & Short 2003). Two other species thriving in brackish waters that can be occasionally found in extremely sheltered and shallow bays and lagoons have also been listed. Black Sea is not included.

Taxonomy follows Flora Europaea (Tutin et al. 1964). Endemic species (found only in the Mediterranean basin) are preceded by the symbol *. Introduced species are preceded by the symbol #. Some of the commonest synonyms found in Mediterranean literature (if any) are sometimes placed after the currently accepted name.
