Abstract

We present the results of astudy on the vascular flora of the Rocche di Entella (Contessa Entellina, Palermo province); thisbiotope, extending over an area of 178 hectares and including a Nature Reserve, has been recognizedas a Site of Community Interest (ITA020042). The biotope is characterized by theMessinian gypseous-sulphureous series and falls within the lower mesomediterranean bioclimaticbelt, with upper dry ombrotype, locally tending towards thermomediterranean thermotype.Local landscape is affected by prolonged historical exploitation of the territory, which led to theimpoverishment of climacic forest communities, almost totally replaced by secondary vegetation(grasslands) and cultivated areas (annual crops). Floristic investigations led to the elaboration ofa checklist including 415 infrageneric taxa, belonging to 267 genera and 62 families. Endemicsare represented by 18 infrageneric taxa (4,4%), among which there are Crepis sprengeli, Erysimummetlesicsii, Odontites rigidifolius, Cymbalaria pubescens, Brassica villosa subsp. tinei,Ophrys panormitana, Malva agrigentina, Gypsophila arrostii, etc. Other species of phytogeographicalinterest are Allium cupanii, Matthiola fruticulosa and Stipa barbata, as well as some entitiesclosely linked to the outcrops of Messinian evaporitic series (Sedum ochroleucum, S. gypsicola,Diplotaxis harra subsp. crassifolia and Chaenorhinum exile).
