For the purpose of the present study we considered as Italian endemics those
specific and subspecific taxa occurring in Italy that are not found
elsewhere with the exception of Corsica (France) and Malta. This study
presents an updated list of the endemic taxa in the Italian flora, including
their geographical distribution at regional level. Italy is characterized by
1371 endemic species and subspecies (18.9% of the total vascular flora):
three taxa belong to Lycopodiidae, one to Polypodiidae, two to Pinidae and
1365 to Magnoliidae (three paleoherbs, 221 monocots and 1144 eudicots). The
endemic flora belongs to 29 orders, 67 families and 304 genera. Sicily,
Sardinia, Calabria and Abruzzo are the four regions richest in endemics.
About 58% of endemics are confined to a single administrative region. The
most represented orders, families and genera are: Asterales, Caryophyllales
and Asparagales, Asteraceae, Plumbaginaceae and Caryophyllaceae, Limonium,
Centaurea and Hieracium, respectively. The phytogeographic
isolation of Sardinia and Sicily and the separation
of peninsular Italy from Northern Italy is confirmed. The relative
isolation of Puglia with respect the remaining southern Italian pensinsular
regions is also confirmed. Alpine region endemics (from northern Italy) are
underrepresented.
