This paper presents the results of floristic researches in the "Monte Penna" Natural Reserve, a mountain area located south of Monte Amiata. The area (about 1110 hectares) is one of the fossil islands of southern Tuscany. After a brief description of the geomorphological, climatic and vegetation features of the area, the list of the vascular flora is given, which was made out through floristic field researches, bibliography and herbarium specimens (SIENA, Herb. Selvi, Herb. Frignani). The checklist includes 640 native species belonging to 87 families and 323 genera, plus 13 introduced species. The life-form spectrum shows the dominance of hemicryptophytes (43.4%) over therophytes (26.6%) and geophytes (15.8%), while the chorological analysis highlights the codominance of the Eurosiberian and Mediterranean elements with an important contribution of Boreal and Apenninic species. Floristic similarity with respect to the other calcareous fossil islands in Southern Tuscany is analysed. Although only two narrow-ranged endemics (Cerastium arvense ssp. arvense var. etruscum and Ornithogalum etruscum) are found in the area, the presence of rare or noteworthy plants such as Delphinium fissum, Silene muscipula, Prunus mahaleb, Anchusella cret-ica, Centaurea scabiosa, Sternbergia colchiciflora and others underscores the phytogeographical relevance of the Reserve and its role as a regional hot-spot for the conservation of plant diversity.

Abstract
This paper presents the results of floristic researches in the "Monte Penna" Natural Reserve, a mountain area located south of Monte Amiata. The area (about 1110 hectares) is one of the fossil islands of southern Tuscany. After a brief description of the geomorphological, climatic and vegetation features of the area, the list of the vascular flora is given, which was made out through floristic field researches, bibliography and herbarium specimens (SIENA, Herb. Selvi, Herb. Frignani). The checklist includes 640 native species belonging to 87 families and 323 genera, plus 13 introduced species. The life-form spectrum shows the dominance of hemicryptophytes (43.4%) over therophytes (26.6%) and geophytes (15.8%), while the chorological analysis highlights the codominance of the Eurosiberian and Mediterranean elements with an important contribution of Boreal and Apenninic species. Floristic similarity with respect to the other calcareous fossil islands in Southern Tuscany is analysed. Although only two narrow-ranged endemics (Cerastium arvense ssp. arvense var. etruscum and Ornithogalum etruscum) are found in the area, the presence of rare or noteworthy plants such as Delphinium fissum, Silene muscipula, Prunus mahaleb, Anchusella cret-ica, Centaurea scabiosa, Sternbergia colchiciflora and others underscores the phytogeographical relevance of the Reserve and its role as a regional hot-spot for the conservation of plant diversity.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
