Chromatographic analysis of the flavonoid compounds in leaf extracts support field and morphological studies which lead to the interpretation of Vernonia guadalupensis Heller as a natural hybrid between V. lindheimeri Engelm. and Gray and V. interior Small. Of 16 major flavonoids found in leaf extracts of the parental species, 8 were found only in V. lindheimeri , 3 were found only in V. interior ; 5 were common to both. All 16 were found in leaf extracts of V. guadalupensis.
