'''Saxifragaceae''' is a [[plant]] family with about 640 known species in 33 accepted [[genera]].<ref name="Christenhusz-Byng2016">{{cite journal |last1=Christenhusz |first1=M. J.

The flowers are [[hermaphrodite|hermaphroditic]] and [[actinomorphic flower|actinomorphic]]. They have 4 or 5 [[petal]]s and 5 or 10 [[stamen]]s.
 
 
 
Well known species include:
 
*''[[Bergenia cordifolia]]''
 
*''[[Saxifraga stellaris]]''
 
*''[[Saxifraga oppositifolia]]''
 
*''[[Saxifraga paniculata]]''
 
 
 
[[Parnassiaceae]] have sometimes been treated as part of this family, although they are only distantly genetically related and are now placed in [[Celastraceae]].<ref name="apgiv">{{Cite journal |last=Angiosperm Phylogeny Group |year=2016 |title=An update of the Angiosperm Phylogeny Group classification for the orders and families of flowering plants: APG IV |journal=Botanical Journal of the Linnean Society |volume=181 |issue=1 |pages=1–20 |url=http://onlinelibrary.wiley.com/doi/10.1111/boj.12385/epdf |format=PDF |accessdate=2016-04-10 |doi=10.1111/boj.12385 }}</ref>

==Evolution==
 
Saxifragaceae are found mostly in the Northern Hemisphere, with centers of diversity in the Himalayas, East Asia, and Western North America. The greatest diversity is in the [[Pacific Northwest]] region of North America.<ref name="autogenerated86">{{Cite journal |url= |title=Phylogeny, divergence times, and historical biogeography of the angiosperm family Saxifragaceae |last= |first= |date= |journal=Molecular Phylogenetics and Evolution |volume=83 |pages=86–98 |doi=10.1016/j.ympev.2014.11.011 |pmid=25479063 |year=2015 |last1=Deng |first1=Jia-bin |last2=Drew |first2=Bryan T. |last3=Mavrodiev |first3=Evgeny V. |last4=Gitzendanner |first4=Matthew A. |last5=Soltis |first5=Pamela S. |authorlink5=Pamela S.

The family is divided into two main lineages – the saxifragoids, which includes genera ''Saxifraga'' and ''Saxifragella'', and the heucheroids, which includes all the other genera. The heucheroids are composed of eight tribes: Darmera (''Astilboides, Bergenia, Darmera, Mukdenia, Orestitrope,'' and ''Rodgersia''), Heuchera (''Bensoniella, Conimitella, Elmera, Heuchera, Mitella, Tellima, Tiarella,'' and ''Tolmiea''), Peltoboykinia (''Chrysosplenium'' and ''Peltoboykinia''), Micranthes (''Micranthes''), Boykinia (''Boykinia, Bolandra, Hieronymusia, Jepsonia, Lithophragma, Sullivantia, Suxdorfia'' and ''Telesonix''), Saniculphyllum (''Saniculphyllum''), Leptarrhena (''Leptarrhena'' and ''Tanakaea''), Astilbe (''Astilbe'' and ''Saxifragopsis''), and Cascadia (''Cascadia'' and ''Saxifragoides'').<ref name="autogenerated86"/>
