The leaf alcoholic extracts of six native Argentine species of Vicia (subg. Vicilla, sect. Australis: V. gramineae, V. macrogramineae, V. epetiolaris, Y. montevidensis, V. nana and V. pampicola) and one adventitious species (subg. Vicia, sect. Vicia: V. sativa subsp. nigra) were studied by bidimentional paper chromatography. Eighty phenolic compounds were found in 107 individuals that were studied. In spite of the high intraspecific variability, observed in all the species, the chromatographic identification was possible because of the presence of specific compounds in each of them. Numerical taxonomy methods were applied to estimate the degree of similarity. The distance and association coeficients used generated congruent phenograms that showed seven main groups which agreed with the seven species that were studied and confirm the exomorphological classification.
