abstract

The results on the phytosociologic analysis on some shrub caducous meso-higrophylous communities are here presented. The study involves the north-western part of Sardinia (Italy), with major attention to the carbonatic and volcanic sectors of 'Sassarese' and 'Nurra'. The new associations Vinco sardoae-Rubetum ulmifolii, Crataego monogynae-Pyretum amygdaliformis and Rhamno alaterni-Spartietum juncei are here described. The first two are included in the Rhamno-Prunetea class, Pruno-Rubion ulmifolii alliance, the last is referred to Quercetea ilicis class, Pistacio-Rhamnetalia alaterni order.
