FAMILY INDEX

FAMILY CODE: SAXIFR
FAMILY SCIENTIFIC: Saxifragaceae
FAMILY AUTHORITY: A.L. de Jussieu 1789
FAMILY COMMON: Saxifrage Family
FAMILY SUMMARY: If narrowly circumscribed (as here), a family of about 35 genera and 500-650 species, herbs (mianly perennial), nearly cosmopolitan, but especially diverse in warm temperate and cold temperate regions of North America and Eurasia. The circumscription of a much narrower Saxifragacaeae is clearly warranted, based on a wide variety of data, and strongly corroborated by molecular data (Morgan & Soltis 1993 and many later references).
FAMILY REFERENCE: Wells & Elvander in FNA (2009); Spongberg (1972); Morgan & Soltis (1993); Soltis in Kubitzki, Bayer, & Stevens (2007). [also see GROSSULARIACEAE, HYDRANGEACEAE, ITEACEAE, PARNASSIACEAE, and PENTHORACEAE]
