All divergence time estimates assume a chloroplast mutation rate of 3.26 × 10-10 substitutions/site/year. Coalescent units reported are based on either high (100,000) or low (10,000) effective population (Ne) sizes. Maximum likelihood (ML) branch lengths are shown as substitutions/site. Estimated divergence times are presented in years (top), generations (middle) and coalescent units for high/low Ne (bottom).
