Chromosome numbers have been used in plant taxonomy, and they are stillfundamental for taxon delimitation and genome evolution studies. SouthAmerica is one of the most diverse continents in terms of plant species andthere is a considerable number of species not yet analyzed. Accumulatedknowledge about plant chromosome numbers has been compiled fromonline databases, and here we present an overview. The CCDB is one ofthe largest plant cytological databases and includes data for around 18% ofknown vascular plants in the world. In this work, we review the informationcontained in CCDB and in three databases with exclusive information forSouth America. At present, the three existing databases comprise around1800 plant taxa related to specific regions, countries, or biomes. Efforts arenecessary to expand cytological knowledge and collect all the availableinformation in a plant chromosome database for this continent.
