Résumé :	The flavone-flavolol ratio (fo/fl) for Dicotyledoneae is studied through graphic comparisons between indices indicative of morphological tendencies: the herbaceousness and Sporne indices. These comparisons show a tendency toward the reduction of flavone biosynthesis in arboreous and shrubby taxa. Ligneous families (HI ≤50.0) and morphologically more primitive families (SI ≤55) possess fo/fl <1.00. However, the relationship between evolutionary status of families with fo/fl values is not simply linear in Dicotyledoneae, because more advanced families are also characterized by a wider range of variation in fo/fl values.
