saxifragales
An order of flowering plants near the base of the eudicots; DNA sequence analysis has indicated that this order includes few families that have been associated together in previous classifications. The order's exact relationships to other orders are still under study, but Saxifragales appear to be related to the rosid eudicots. They include 13 small to moderately sized families and perhaps around 2300 species. There are two categories: woody species that are sometimes wind-pollinated, and insect-pollinated herbs. The members are difficult to characterize morphologically but fall into several sets of families that have been considered closely related by most authors.
