THE SUBFAMILIAL, TRIBAL AND SUBTRIBAL NOMENCLATURE OF THE RUBIACEAE

Summary Recent renewed interest in the suprageneric classification of the Rubiaceae has made a clarification of the subfamilial, tribal, and subtribal nomenclature an urgent necessity. Presented here is a list of all suprageneric names published within the Rubiaceae, with an indication of their nomenclatural status; names of segregate families are also 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 ten tribal names are validated with Latin descriptions or diagnoses.
