A cladistic analysis was performed including five Cretaceous and 31 extant taxa within Saxifragales using a combination of molecular sequence and morphological data in order to elucidate the utility of extinct taxa in illuminating saxifragalean evolution. The results suggest that Saxifragales as well as most major infraordinal clades lack unambiguous morphological synapomorphies among the characters examined; that the major lineages of Saxifragales were distinct by ca. 90–70 Ma; and that the ca… Expand
