Three new species belonging to the genus of Randia are recognised and described by the authors of the paper. The R. colimensis is an endemic of the Volcano Colima and surroundings, vicarious of R. xalapensis Mart. et Gal. largely distributed in the Sierra Madre Oriental from Tamaulipas and San Luis Potosi to Tabasco and Chiapas. R. dionisi and R. similis are strict endemics of Oaxaca, related vicarious species of R. laevigatoides Borhidi and R. loniceroides Dwyer et Lorence, respectively.
