† Complete plastomes sequenced, assembled, and annotated in this study; LSC, long-single copy; SSC, short-single copy; IR, inverted repeats; DR, direct repeats; tRNA, transfer RNA; rRNA, ribosomal RNA. Numbers in parentheses represent the number of duplicated genes due to their position in the inverted repeat region.
