Random local clocks (RLC) chronogram of Xanthorrhoeaceae from combined ndhF and trnL - trnF (chloroplast DNA) sequences. Analysis used BEAST with a Yule tree model. Branches are colored by inferred local clock rates: red = fastest, blue = slowest, orange and green = intermediate, and each branch is labelled with the actual rate (substitutions site⁻¹ Myr⁻¹ × 10⁴). Filled pointers show likely rate shifts (to right = upwards, to left = downwards); open pointers show possible alternatives. Clade labels with bars indicate subfamilies. The scale indicates time before present (Ma).
