Integrazioni alla flora vascolare dell’Italia centrale.

Additions to the vascular flora of the Central Italy. In this work new floristic records for 46 units are reported for some regions of Central Italy. Particularly 25 are new or confirmed to Abruzzo, 1 is new to Marche and 1 to Molise. In addition new distribution data for 18 units rare or interesting in Abruzzo and 1 in Molise regions have been recorded. The survey was carried out from 2010 to 2015 through field research, revision of herbarium specimens and literature studies. Some recorded species are particularly interesting from a phytogeo¬graphical or conservational point of view as they are very rare in Cen¬tral Italy. The results also show a high presence of new alien species.
