Preliminary checklist of the Italian gypsophilous flora

The richness and uniqueness of the flora growing on gypsum substrates in Italy is known since the XIX century (Macchiati, 1888). Furthermore, the concept of plant gypsophily can be defined as the exclusiveness (or virtually exclusiveness) for living in gypsum outcropping rocks.
