A comparative study of morphology and pollination of Veronicastrum virginicum in praire and wetland habitats.

Differences in habitat can determine differences in morphology of populations of a species. Differences in morphology can lead to changes in main pollination system. In this study, we compare both the morphology and pollination systems of a Missouri native flower, Veronicastrum virginicum, which grows in both prairie and wetland habitats. We conducted morphological measurements and detailed pollination system studies in populations in both habitat types. Our results show that stigma and stamen length are statistically different in the two habitats, however, flower and fruit measurements showed no differences. The main pollinator in the prairie is Apis mellifera (54% total pollen flow), while the main pollinator in the wetland is halictid bees (79.5% total pollen flow). Bombus were present and pollinating (11.4%) in the prairie, but absent in the wetland population. Further studies are needed to determine if the differences in morphology are connected to the differences in main pollinator.
