Maximum parsimony strict consensus tree from the Saxifragales data set. Data set of combined nuclear SSU and LSU rDNA, chloroplast rbcL, atpB, and matK. Strict consensus of 9 trees. Bootstrap support values are shown above the lines. The minimum length tree was 8282 steps (consistency index minusuninformative sites 0.3975, retention index 0.5609, rescaled consistency index 0.2750). Although the sister relationship between Cynomorium and Crassulaceae is seen in the shortest trees, bootstrap support for this clade is low.
