Checklist of gypsophilous vascular flora in Italy.

Our understanding of the richness and uniqueness of the flora growing on gypsum substrates in Italy has grown significantly since the 19 century and, even today, new plant species are still being discovered. However, the plants and plant communities, growing on gypsum substrates in Italy, are still a relatively unknown subject. The main aim of this paper was to elaborate a checklist of the Italian gypsophilous flora, to increase knowledge about this peculiar flora and for which conservation efforts need to be addressed.
