The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, ornamental cultivars, and historically some dye plants.
Galium is a large genus of annual and perennial herbaceous plants in the family Rubiaceae, occurring in the temperate zones of both the Northern and Southern Hemispheres. Some species are informally known as bedstraw.
Sherardia is a monotypic genus of flowering plants in the family Rubiaceae. The genus contains only one species, viz. Sherardia arvensis or (blue) field madder, which is widespread across most of Europe and northern Africa as well as southwest and central Asia and Macaronesia.

Psychotria is a genus of flowering plants in the family Rubiaceae. It contains 1,582 species and is therefore one of the largest genera of flowering plants. The genus has a pantropical distribution and members of the genus are small understorey trees in tropical forests. Some species are endangered or facing extinction due to deforestation, especially species of central Africa and the Pacific.
Robynsia is a monotypic genus of flowering plants in the family Rubiaceae. It was described by John Hutchinson and was named after his friend and colleague Walter Robyns. The genus contains only one species, Robynsia glabrata, which is found in Ghana, Ivory Coast and Nigeria.

There are, however, only two currently recognized species.
