Summary – A floristic investigation was carried out in “Pizzo Cane, Pizzo Trigna and Grotta Mazzamuto” Nature Reserve,one of the largest in Sicily. In spite of the considerable botanical interest of this area, few data were available from classicand recent literature. Based on field investigations, coupled with bibliographic and herbarium researches, we have listed951 infrageneric taxa belonging to 103 families and 446 genera. A lot of these entities are reported in this area for the firsttime, for others ancient records are confirmed. Life form analysis shows the dominance of therophytes (44,79%) andhemicryptophytes (27,77%). From a chorological point of view, Mediterranean elements show a great incidence (72,12%).Endemism, at different levels, is represented by 59 taxa (6,20% of the local flora); some of these are exclusive of northwesternSicily (Centaurea ucriae, Centaurea umbrosa and Oncostema cerulea), others are endemic to whole Sicily (Erysimummetlesicsii, Helichrysum pendulum, Eryngium bocconii, Leontodon siculus, Ophrys panormitana, Ophrys lunulata, etc.) or tocentral Mediterranean area, i.e. Sardinia, Italian Peninsula, Maltese Islands, Tunisia (Euphorbia amygdaloides subsp. arbuscula,Orchis brancifortii, Arabis rosea, Brassica rupestris, Matthiola incana subsp. rupestris, Dianthus rupicola, Iberis semperflorens,Ophrys oxyrrhynchos, Stipa austroitalica subsp. appendiculata). Some other species are interesting from a phytogeographicaland conservational point of view, e.g. Eryngium pusillum, Ilex aquifolium, Potamogeton pusillum, Rhaponticumconiferum, Sorbus torminalis, Trifolium physodes, Vicia sicula, etc. Furthermore, this area represents the unic sicilian site ofHornungia pauciflora. The high floristic biodiversity of the area is threatened by fire events, reafforestation with allochthonousspecies and other human activities suggesting the urgent need of a more effective policy of sustainable management.
