Individual variation in the magnitude of inbreeding depression (ID) plants and its association with phenotypic traits may have important consequences for mating system evolution. This has been investigated only scarcely, always considering functionally related to autogamy. Here, we explore between individual ID plant associated pollinator attractiveness (related size, corolla size shape) two populations Erysimum mediohispanicum (Brassicaceae). was calculated along entire life cycle plants. In addition, also explored relationship levels heterozygosity. We found significant associations diameter stalk height, being taller larger corollas those undergoing a lower intensity ID. Furthermore, negative heterozygosity, suggesting that large flowers purged their genetic load. Finally, effect on intrapopulation structure. All these findings suggest secularly suffered frequent study populations. Because is trait frequently selected by pollinators E. mediohispanicum, believe observed this could be mediated pollinators, probably throughout an increasing biparental inbreeding, geitonogamy or
