This article summarizes and analyzes some of the data published in “Flora Corsica”, in order to characterize the Corsican flora (vascular plants). This analysis focuses on different aspects such as diversity (species richness, richest families), abundance (global, in each vegetation belt, in each habitat and substrate types), longevity and life forms (in all the studied area, in each vegetation belt) and phenology (flowering curves). The results are, whenever possible, compared with those of other geographic regions, particularly from the Mediterranean. They help outlining typical Mediterranean patterns, characterizing the Corsican vegetation belts, and identifying characteristics specifically related to the flora of Corsica. Key-
