SUBFAMILIAL, TRIBAL AND SUB-TRIBAL NOMENCLATURE OF RUBIACEAE

Recent renewed interest in the suprageneric classification of the Rubiaceae has made a clarification of the subfamilial, tribal and subtribal nomenclature an urgent necessity. A list of all suprageneric names published within the Rubiaceae is presented, with an indication of their nomenclatural status; names of segregate families are included. Attention is drawn to various problems concerning the interpretation of the International Code of Botanical Nomenclature with regard to the names of taxa published between the ranks of family and genus. Three subfamilial and 10 tribal names are validated with Latin descriptions or diagnoses.
