Figure 2

Maximum likelihood phylogram for all complete plastomes. Branch lengths are given in substitutions per site. The star indicates the hypothesized origin of the mitochondrion-to-plastid horizontal gene transfer event. The cross indicates the hypothesized origin of the 150 bp inversion in subtribe Olyrinae. Nodes are supported at a 100% maximum likelihood bootstrap score unless reported. All nodes were supported with a posterior probability of 1.0.
