§Models selected by the hLRT can vary depending on the model parameter addition hierarchy used; models used for analysis were those chosen by the AICc and at least one version of the hLRT [for matK pos 1, AICc was used]. The listed numbers of variable characters in the "both global and Saxifragales" portion of the table refer to the global data set. Akaike weights of the chosen model were computer for the total number of characters (all) and the number of variable characters (variable). * Both the global and Saxifragales data sets included atpB codon positions 1 and 2, but the models chosen for these data partitions differed between the two data sets (simpler models were chosen for these partitions with the Saxifragales data set, which comprises more closely related taxa than does the global data set).
