Chronogram showing the evolutionary distances (in millions of years) between the species and accessions analysed in the low copy gene locus phylogenetic analysis of this study. Numbers to the left of nodes show the age of the node in millions of years ago (Mya). Node bars give the 95% highest posterior density (HPD) for the node height. The scale at the bottom gives millions of years before present in 2.5 million year increments. Arthraxon lanceolatus and Arthraxon prionodes are employed as an outgroup. Images were drawn with FigTree [83] prior to finishing with Adobe Illustrator
