%X the diversity of floral visitors (dfv) and the frequency of visits (fv) were related to some reproductive traits, in 30 co-occurring asteraceae species of chaco forests from c¨®rdoba (argentina). dfv and fv were very different between species and apis mellifera was the most frequent visitor of flowers. the dfv and the fv showed significant correlations: negative with flowering period and positive with the number of open flowers per plant. results suggest that the reproductive assurance by autonomous selfing may be limited, since pollinator activity plays an important role in plant reproduction. both, species with and without autonomous selfing, showed an increase in the number and size of the fruits produced.
