Other claims from this paper (6)
- Observation Thirteen of 20 putative allozyme loci were variable across the three Cephalanthera species.
- Observation There was a complete lack of allozyme variation within each Cephalanthera species.
- Observation No evidence of hybridisation was found among the three Cephalanthera species.
- Mechanism Korean populations of C. erecta and C. falcata may have been established by a single introduction from a genetically depauperate ancestral population.
- Mechanism C. longibracteata may have survived the Last Glacial Maximum in microrefugia in low elevation regions of the Peninsula.
- Mechanism Population bottlenecks are asserted to have reduced the genetic diversity of C. longibracteata.
