Le territoire ibléen est un centre important pour la biodiversité et la spéciation en Sicile. Sa flore endémique représente 105 taxons. Beaucoup sont menacés par différentes activités humaines (agriculture intensive, urbanisation, pâturage, industrialisation). Parmi les taxons endémiques, 39 sont inclus dans la Liste rouge de l'UICN régionale et 32 dans la Liste rouge nationale, 17 Orchidaceae sont protégées par la CITES et 3 par la directive Habitat 92/43. Les familles les plus représentées sont: Asteraceae and Orchidaceae (17%), Lamiaceae (10%). Le spectre biologique de cette flore montre la dominance des géophytes (28,6%), chaméphytes (26,7%), hémicryptophytes (24,8%). L'analyse des habitats montre que les endémiques sont répandues dans les garrigues, parois rocheuses et côtes rocheuses, les prairies sèches, les bois et lieux anthropisés. Nous donnons une évaluation sur l'état de conservation des endémiques de ce territoire et des propositions pour leur protection.
A survey of the endemic flora of the Hyblaean territory, important centre of biodiversity and speciation in Sicily, is presented. The endemic flora of this area consists of 105 taxa. Among them, 39 are included in the IUCN Regional Red List and 32 in the National Red List, 17 Orchidaceae are protected by the CITES and 3 in the EU 92/43 Habitat Directive. The most represented families are Asteraceae and Orchidaceae (17%), Lamiaceae (10%). A large number of species are endemic to Sicily or central-southern Italy and Sicily. The endemic taxa exclusive to the Hyblaean territory are 20. Life form spectrum of the endemic flora indicates the predominance of geophytes (28.6%), chamaephytes (26.7%), hemicryptophytes (24.8%). The analysis of the habitat put in evidence that the endemics are widespread in garrigues, rocky walls and rocky coasts, dry grassland, woods and synantropic places. In this work, ils also provided an assessment of the conservation statua of Hyblaean endemics and proposition for their protection.

Abstract
A survey of the endemic flora of the Hyblaean territory, important centre of biodiversity and speciation in Sicily, is presented. The endemic flora of this area consists of 105 taxa. Among them, 39 are included in the IUCN Regional Red List and 32 in the National Red List, 17 Orchidaceae are protected by the CITES and 3 in the EU 92/43 Habitat Directive. The most represented families are Asteraceae and Orchidaceae (17%), Lamiaceae (10%). A large number of species are endemic to Sicily or central-southern Italy and Sicily. The endemic taxa exclusive to the Hyblaean territory are 20. Life form spectrum of the endemic flora indicates the predominance of geophytes (28.6%), chamaephytes (26.7%), hemicryptophytes (24.8%). The analysis of the habitat put in evidence that the endemics are widespread in garrigues, rocky walls and rocky coasts, dry grassland, woods and synantropic places. In this work, ils also provided an assessment of the conservation statua of Hyblaean endemics and proposition for their protection.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
