摘要

We compared the floral morphologies and pollinator fauna of two sister taxa, Primula hidakana and P. takedana, to obtain a better understanding of the pollination systems of these species. Observations of their floral characteristics revealed that both species are strictly distylous. The flower shape of P, hidakana has a much larger corolla than that of its sister species, and the diameter of its corolla tube mouth was approximately half that of P. takedana. Observations of flower visitors revealed that pollinators of P. takedana, which were small, short-tongued insects, varied more than those of P. hidakana did. The diversity of pollinator fauna in P. takedana implies that P. takedana is unable to restrict the type of insect visitor due to flower structure constraints. We conclude that differences in floral structure between these sister primrose species are associated with pollinator fauna differentiation, which may have contributed to their speciation.
