Floral and vegetative cues for pollination in Lysimachia

Floral and vegetative cues for pollination in Lysimachia

Plants pollinated by the same guild of pollinators often converge in their floral phenotype as a result of pollinator-mediated selection. However, Schäffler et al. also consider evolutionary relationships by studying floral and vegetative scents and colours in floral oil- and non-floral oil-secreting Lysimachia species and analysing the results using phylogenetically controlled methods. They find evidence for correlated evolution between secretion of floral oils and floral, but not vegetative, visual and olfactory cues. The cues correlating with oil secretion were probably selected by Macropis bees, specialized pollinators of Lysimachia species.
