From: Interspecific delimitation and relationships among four Ostrya species based on plastomes
Cladogram of Ostrya species using Bayesian inference (BI) analysis and Maximum likelihood (ML) analysis based on different datasets. Support values are shown for nodes as BI posterior probability (above branches) /ML bootstrap (below branches). The four species are shown by different colors. a – c plastome trees based on different regions; population information for each species is shown at the tips. d nuclear ITS (Internal transcribed spacer) tree; samples for each species are selected from different populations
