General/Distribution: A small family of 4 genera and about 100 species; distributed in tropical and temperate regions; absent from Polynesia, Australia and Eastern South America. 2 genera and 3 species are reported from Pakistan.
Comment/Acknowledgements: The family was treated as tribe Buxeae of Euphorbiaceae by most authorities, for example Bentham and Hooker (Gen. Pl.3:242.1883), J.D.Hooker (Fl.Brit.Ind. 5:267.1885), although its separate identity was established much earlier by Dumortier (Comm.Bot.54.1822) on the basis of the absence of milky sap, styles free from the base, ovules with dorsal raphe. Baillon (Monogr.Bux.et Styloc.1859) and Muell.-Arg. in DC. (Prodr. 16(l):7.1869) were the first to follow Dumortier in recognising its separate identity as a family.
