Here is show the account of floristic exploration in the Sulcis area. This study is based on existing bibliography and has been done through herbarium researches in the main national and international centres. The investigations allowed to take a census of all the works carried out in the Sulcis area, to verify the authors and the explored environment as well as the exsiccata stored in the various herbarium. From the analysis emerges that the coastal and the lagoon areas have been deeply studied since the second half of the XVIth century, the hill and the foot of the mountain areas since after the second world war, while the mountain areas and the rivers are nowadays still less known and sometimes totally unexplored. Is finally put in evidence which areas have a greater need to be researched both from floristic and vegetational point of view.
