Flavonoid Relationships with Other Families
In the preceding chapters we attempted to bring together as much flavonoid occurrence data as possible in order to address the usefulness of the information in dealing with problems of relationships among various groups within Asteraceae. Flavonoid data have been very instructive in certain instances, particularly when dealing with situations at the lower levels in the taxonomic hierarchy, including hybrid systems. Absolute differences are rarely encountered at higher taxonomic levels, but significant tendencies in flavonoid occurrence frequencies are evident among subfamilies and among certain groups of tribes. Flavonoid patterns at the subtribal level leave much to be desired, a problem that wider sampling might help to alleviate.
