The taxa endemic to Italy are 1708, grouped in 70 families and
313 genera. Four genera are narrowly endemic to Italy: Eokochia
(Chenopodiaceae), Rhizobotrya (Brassicaceae), Petagnaea and
Siculosciadium (Apiaceae). Three genera are endemic to Sardegna
and Corse (France): Morisia (Brassicaceae), Castroviejoa and
Nananthea (Asteraceae).
The most represented families (>70 taxa) and genera (>30 taxa)
concerning Italian endemic taxa are (Table 2): Asteraceae (582),
Plumbaginaceae (117), Caryophyllaceae (97), Orchidaceae (87),
Fabaceae (80), and Brassicaceae (78); Hieracium (337), Limonium
(98), Centaurea (73), Ophrys (61), Ranunculus (37) and Taraxacum
(33).
The taxa currently occurring in Italy are 7483, while 568 taxa
have not been confirmed in recent times, 99 are doubtfully
occurring in the country and 19 are data deficient (Table 3).
Out of the 568 not confirmed taxa, 26 are considered extinct
or possibly extinct: Aldrovanda vesiculosa, Anthyllis hermanniae
subsp. corsica, A. hermanniae subsp. sicula, Bromus grossus,
Bulbostylis cioniana, Caldesia parnassifolia, Camelina alyssum
subsp. alyssum, Carlina acanthifolia subsp. utzka, Castroviejoa
frigida, Clematis integrifolia, Helianthemum syriacum subsp.
thibaudii, Helosciadium repens, Herniaria fontanesii subsp.
empedocleana, Launaea nudicaulis, Limonium catanense, L.
intermedium, L. peucetium, Puccinellia gussonei, Ranunculus
fiorii, R. fraelensis, R. hostiliensis, R. monspeliacus subsp. saxatilis,
R. mutinensis, Sonchus palustris, Stratiotes aloides and Suaeda
kocheri. The taxa to be excluded at national level are 177 (see
Appendix S4).
The administrative regions showing the highest number of
taxa (Tables 4 and 5), also considering the regionally non-native
(CAS, NAT, INV) taxa, are: PIE (3535), TAA (3504), LOM (3429),
TOS (3400), VEN (3338) and ABR (3216). By excluding the taxa
regionally non-native (CAS, NAT, INV) at regional level, the
regions with the highest number of taxa are: PIE (3464), TOS
(3370), LOM (3272), ABR (3190), VEN (3169) and TAA (3116).
Cryptogenic taxa are 56, while 430 taxa are taxonomically
doubtful (Table 6).
