[EN] The phytodiversity along an altitudinal gradient inside the crater of the Provincial Geological Reserve «Laguna Azul», on the volcanic field of Pali Aike, province of Santa Cruz (Argentina) has been studied. High biodiversity is reported, since on a very small surface area taxa of different plant communities are present, some of which are rare or absent in the surrounding territories.
