摘要：This paper presents, at regional level, a physionomic floristic description of extra-ondean Patagonia. We analysed the information with the greatest regional synthesis obtained in the last decades, specially the one that provided cartographic data. As a result of this synthesis, phytogeographical districts were subdivided, ecotones were delimited and boundaries were either confirmed or modified. The result is a map where we propose 16 physionomic floristic units: 12 included in the six districts of the Patagonian province, two in the Monte province and two in ecotones. Existing phytosociological information has been added to the description of each unit
