Saxifragales

Saxifragales is an order of flowering plants in the superrosid clade of the eudicots. It contains 15 families and around 100 genera, with nearly 2,500 species.

They can be found in a wide variety of environments, from deserts to fully aquatic habitats, with species adapted to ......read more on Wikipedia.
