Unrooted 50% majority rule tree from Bayesian analysis of the combined AFLP dataset for all New Zealand and Australian species of Ourisia. Posterior probability values ≥50 are shown near each branch. Colours follow Figure 3. Ourisia integrifolia, the sole Australian species, is the sister to all the New Zealand species  and thus the root of the tree. Location of the large-leaved group is also shown. All photos by HMM except O. macrocarpa subsp. calycina (P. Knightbridge) and O. modesta (C. Ogle).
