| Abstract: | ABSTRACT The Euganean Hills are a volcanic mountainous complex, which rises from the eastern Po Plain, and consists of about one hundred hills, rising from 80 m to 604 m above sea level. In the studied area, 1158 taxa of Tracheophytes have been collected. The chorological and life-form analyses of this flora have shown the predominance of the Mediterranean s.l. elements and of the hemicryptophytes, followed by the therophytes. The chorological aspect of this floristic complex was analysed. A cross-spectrum was calculated to see how life-forms are represented in the different chorotypes. A comparison with the biological and chorological spectra of the Veneto Region and of Italy as a whole was also carried out. Several species of remarkable floristic and phytogeographical interest have been found, as well as some included in the national and Regional lists of protected species. |
