The type species is ''Ridsdalea grandis'' (Korth.) J.T.Pereira, which was renamed from the basionym ''Gardenia grandis''. Several other species have been reassigned from other genera: notably ''Rothmannia'', which is now reserved for African species. Its native range is southern China, Indo-China, Malesia and New Guinea.

Rubiaceae
Rubiaceae () is a family (biology), 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 Petiole (botany), interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 14,100 species in about 580 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 (''e.g.'', ''Gardenia'', ''Ixora'', ''Pentas''); and historically some dye plants (''e.g.'', ''Rubia''). Description The Rubiaceae are morphologically easily recognizable as a coherent group by a combination of characters: opposite or whorled leaves that are simple and entire, ...
