 Currently, in most molecular research concerning the family Rubiaceae, the classification with three subfamilies (Cinchonoideae, Ixoroideae, and Rubioideae) is followed.However, an alternative view is proposed where only two subfamilies are recognized, an expanded Cinchonoideae (that includes Ixoroideae, Coptosapeltaeae and Luculieae) and Rubioideae.The adoption of the Melbourne Code for botanical nomenclature had an unexpected impact on many names that have been long in use and are well-established in literature.
