摘要：

The taxonomical composition and an analysis of four ecological characteristics of the 46 endemic species occurring in the lower Duero Basin (CW Iberian Peninsula) have been made. A comparative analysis of the results reveals that this endemic flora does not comply with the general patterns previously observed in other floras. Predominant life forms are hemicryptophytes (43%) and chamaephytes (22%). As tar seed-dispersal is concerned, 54% of the endemic species lack any noteworthy adaptative feature. 89% of the endemic species are pollinated by animals (mostly by insects) and only 1 species is dioecious. Following binary classification of the above characteristics have been used to plot statistically significant associations.
