Contributo alla conoscenza della flora dell'Alpe della Luna (Appennino Aretino, Toscana)

Contribution to the knowledge of the vascular flora of Monte Beni and Sasso di Castro, two ultramafic mountains in Upper Mugello (Northern Tuscany)

“…The spectra from other two Apennine and antiApennine sites, Monte Cetona (Mazzeschi & Selvi, 1999) and Alpe della Luna (Raffaelli & Rizzotto, 1991), show more similarities no matter the different lithology, the first being formed by limestone the second by sandstone and marl.…”

A new plant community with the strictly endemic "Cirsium alpis-lunae" (Asteraceae) in the Northern Apennines (Italy) and considerations on the alliances "Senecionion samniti" and "Adenostylion alpinae"

“…As above mentioned, this lack of data is mainly due to the difficulty of exploration of the habitat occupied by this species, constituted by steep and unstable slopes, which cannot be visited without specific techniques and mountaineering equipment for vertical works (as we did). We surveyed all the known locations where occurrences of C. alpislunae plants were reported (Brilli-Cattarini & Gubellini, 1991;Raffaelli & Rizzotto, 1991;Gonnelli, 1995;Viciani et al, , 2004Casavecchia et al, 2014;Gennai et al, 2015) and carried out 16 surveys using the phytosociological method (Braun-Blanquet, 1932, 1951Biondi, 2011). We surveyed all the sites where C. alpis-lunae had a relevant cover value, i.e.…”

“…Cirsium alpis-lunae Brilli-Cattarini & Gubellini (Asteraceae) is a strictly endemic yellow-flowered thistle rather recently discovered and described in the northern Apennines, near the conventional border with the central Apennines (Brilli-Cattarini & Gubellini, 1991). Its occurrence was investigated and reported in regional and national floristic and vegetation studies (Raffaelli & Rizzotto, 1991;Gonnelli, 1995;Viciani et al, , 2004Viciani et al, , 2010Conti et al, 1997Conti et al, , 2005Conti et al, , 2007Casavecchia et al, 2014;Gennai et al, 2015;Bartolucci et al, 2018). Nonetheless, because of the difficulties in accessing its typical sites of occurrence, coenological surveys concerning the communities where it grows had never been conducted yet.…”

Contributo alla conoscenza della flora delle zone umide planiziarie e collinari della Toscana orientale: la provincia di Arezzo (Italia centrale)

“…Per l'attribuzione dell'elemento geografico sono stati consultati gli atlanti di Meusel et al (1965;1978) e di Meusel & Jäger (1992) e sono stati inoltre utilizzati i lavori di Rechinger (1988), Baldini (1995, Raffaelli & Rizzotto (1991), Sforzi & Selvi (1999), Arrigoni (2003) e Viciani & Raffaelli (2003. Le specie esotiche, in base al loro comportamento nell'area indagata, sono state suddivise in tre categorie (casuali, naturalizzate ed invasive) come riportato da Camarda et al (2005).…”
