Flowering plants (phylum Magnoliophyta, Kingdom Plantae) have been classified by Classes, Orders, Families and Species. Ordination is alphabetical.
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.
Figure S1. Mediterranean percentages of the world sponge families and genera for each demosponge order
The total numbers of Mediterranean families (F), genera (G) and species (S) are given.
Figure S2. Distribution of the recorded demosponge species (outer circle) and genera (inner circle) richness in distinct zoogeographic areas of the Mediterranean
Numbers of species for each area are given outside the outer circle and number of genera inside the inner circle. AD: Adriatic Sea, AE: Aegean Sea, AL: Alboran Sea, IB: Ionian Basin, LB: Levantine Basin, NWM: north-western Mediterranean, SWM: south-western Mediterranean, TS: Tunisian Plateau/Gulf of Sidra [for the division of the Mediterranean we consulted 1,2,3].
