The Palermo province is one of the most interesting areas in Sicily with respect to the plant biodiversity. In this territory 2148 specific and infraspecific taxa occur. i.e. 80% of the vascular flora of the region; furthermore 232 of such taxa are endemic. i.e. 60% of the whole eodemics in Sicily. The distribution of this remarkable heritage is represenred in an integrated map in which GIS data are analytically combined with other ones from different sources. The incidence and distribulion of the flora of the province (which is divided 167 quadrants) are comprehensively shared out through a chromatic range or eight classes while incidence and distribution of endemics are displayed within each quadrant through five red dots of different diameter.
