In this contribution the authors present the results of a floristic research involving a few calcarcous formations of centre-castern Sardinia in Barbagia di Seulo: Monte Tonneri and Monte Arqueri. The found floristic component is made up of 508 entities subdivided into 76 familics and 305 genera. The endemic contingent is represented by 62 species. 12.20% of the entire flora. The analysis ofthe growth forms has shown a high percentage of herbaccous speics:the spectrum has shown the dominance of Mediterranean elements. The largest per- centage of the endemic component refers exclusively to the Sardinian sector.
