dc.description.abstract Plants with similar traits compete for resources. If related taxa share similar traits, phylogenetic relationships may predict competitive outcomes. Although plants compete for pollinators, flowers are rarely considered in community-assembly theory. I tested the hypothesis that plant communities are structured by competition for pollination. I inventoried communities at three spatial scales, measured seven flower traits, and tested the observed patterns against those generated by a null model to judge if community members were more or less similar in floral traits than expected by chance. I also measured the phylogenetic relatedness of community members to gauge trait-conservatism. Clustering of visually attractive traits suggests they promote facilitation of pollinators while over-dispersion of morphological traits suggests they partition pollinators in to avoid competition. Communities were phylogenetically even, but relatedness did not explain floral trait patterns. I suggest that flowers represent an ecological niche through which species can be sorted. en_US
