Saxifragaceae A.L. de Jussieu. Saxifrage Family.
If narrowly circumscribed (as here), a family of about 35 genera and 500-650 species, herbs (mainly perennial), nearly cosmopolitan, but especially diverse in warm temperate and cold temperate regions of North America and Eurasia. The circumscription of a much narrower Saxifragaceae is clearly warranted, based on a wide variety of data, and strongly corroborated by molecular data (Morgan & Soltis 1993 and many later references).
