Islands and plants: preservation and understanding of flora on Mediterranean islands

the present composition and the species richness of the region’s vascular flora.
For example, because it is part of the African continental shelf, Lampedusa
hosts a remarkable number of south, southwest, and southeast Mediterranean
and Mediterranean-Irano-Turanian species (e.g., Suaeda pelagica, Caralluma
europaea subsp. europaea, and Echinops spinosus subsp. spinosissimus).
Similarly, because of their repeated past connections with the main island, the
Egadi islands host a high number of Sicilian endemics (Table 3).
