Heterodichogamy avoids inbreeding in Kingdonia

Heterodichogamy, an unusual kind of reproductive heteromorphy, is hitherto unreported in Ranunculales and is known from only one other genus in the basal eudicots. Wang et al. study flowers of Kingdonia uniflora, an isolated endemic of China, in the field and determine that it posesses heterodichogamous flowers with protandrous and protogynous morphs that have a 1 : 1 ratio. Both set fruit equally successfully; although Kingdonia has uniflorous ramets and clonal reproduction appears to be dominant, heterodichogamy might be an adaptation to avoid mating between ramets from a common mother genet.
