Resumen:
The aim of the study is to provide a chorological interpretation of the mountains in Central Argentina in order to establish its actual phytogeographic position and to discuss the status of the Sierra Chaco District within Argentina. A subdivision of the regional flora (more than 600 species) into 6 chorotypes (phytogeographic groups or categories) and the classification and ordination of 20 sites along an altitudinal gradient (1000 to 2600 m) on the basis of chorotypes frequencies are presented. The classification analysis shows that the sites are grouped according to their chorotype frequencies into two main clusters comprising sites above and below 1850 m respectively. It is discussed whether sites above that boundary belong to the Chaco Phytogeograpic Province or should be included in a different unit.
