Abstract
Examining literature references and analysing all the specimens preserved in the main herbaria of Sardinia and Tuscany, at present 184 aliens are to be listed in this region, 29 of them as naturalised, 16 as casuals, 8 as uncertain and 131 as escaped from cultivation. According with previous papers, a card for each species, with reference to specific name, origin, ecology, distribution in Italy and in Sardinia provinces is provided. A particular attention is ma de at weeds - that are 55 (30% of the aliens) in order to valuate their role in the variation of the native vegetation and of the cultures.File | Dimensione | Formato | |
