POLYGALACEAE (milkwort family)
Nineteen to 23
genera, about 925 species, nearly worldwide.

Polygalaceae contain species that are cultivated as ornamentals or are used
medicinally. The genus Xanthophyllum Roxb. (sometimes segregated into
its own family), which occurs from southeastern Asia to Australia, contains
some species used for dyes and seed oils.
