Fig. 3

Whole plastid phylogram showing the relationships of Tripidium species to other members of the Andropogoneae. Phylogram, based on whole chloroplast alignment, representing the most likely topology from two independent runs of RAxML comparing whole chloroplast alignments of nine Tripidium accessions (eight sequenced and assembled in this study) with 45 representative members of the Andropogoneae (Saccharum spontaneum SES196 was also sequenced and assembled in this study). Arundinella deppeana is used as outgroup. The two slashes (//) indicate that the long branch linking the outgroup to the remainder of the tree has been reduced by 80% so that internal relationships can be more clearly seen. Numbers next to nodes represent SH-aLRT bootstrap, non-parametric bootstrap and Bayesian inference confidence values where * represents 100/100/1. The scale bar at the base of the phylogeny represents the expected number of substitutions per site. Brackets and annotation at the right of the phylogeny show the extent of the core Saccharinae, core Sorghinae and the core Andropogoneae. Images were drawn with FigTree [83] prior to finishing with Adobe Illustrator. Currently accepted members of the Saccharinae are represented by a double dagger (‡) and currently accepted members of the Sorghinae are represented by a section sign (§)
