Abstract

The flora of Monte Arcosu has been studied and 520 taxa have been found. Among these taxa, 492 are species and 28 subspecies belonging to 303 genera and 90 families. The rich variety of plant life in the Monte Arcosu area in comparison with other studied areas of Su1cis is pointed oul. Analysis of the biological spectrum showed that therophytes make up 44% of the total, confirming the full Medi terranean nature of the area. A comparison with the biological spectra of other floras shows similar values, except for the therophytes which seem considerably ]ower, and confirms the prevalence of wood and shmb formations. The chorological spectrum shows dominance of Mediterranean elements (75%), with significant presence of the southwestern Mediterranean component (16%). The number of endemic plants was found to be 9% with dominance of Sardinian-Corsican elements (37%).
