Late Panama, Guettarda L. (cf. †Guettardidites; †= fossil taxon) Canthium Lam. (as †Rubipollis oblatus) Australia, a probable fifth genus, alternate-leaved †Paleorubiaceophyllum eocenicum Tennessee/Kentucky, U.S.A. The record represents three subfamilies (Rubioideae, Ixoroideae, Cinchonoideae) widely separated geographic regions, implying an earlier origin From Oligocene, there six accepted Coprosma J. R.
