Rubiaceae is a family of flowering plants, variously called the madder family, bedstraw family or coffee family. Other common plants included here are gardenia, cinchona, sweet woodruff, partridgeberry, gambier, ixora, and noni. A number of traditionally accepted families (Dialypetalanthaceae, Henriqueziaceae, Naucleaceae, and Theligonaceae) are now incorporated within the Rubiaceae following genetic research by the Angiosperm Phylogeny Group. As now circumscribed, there are about 650 genera and more than 13,000 species in Rubiaceae.
