Description
Summary:Endemism is one of the main considerations in historical biogeography and one of the most important criteria when establishing conservation priorities. Worldwide, more than 90% of the plants listed in conservation categories are endemic to one country. In Chile, 45% of the flora is endemic, currently considering 83 endemic genera and 4 endemic families, elevated numbers compared to the rest of Latinamerica. However, the high rate of changes in taxonomy, based on studies of molecular systematics has produced modifications in this list. This study aims at discussing such modifications and in this way, contribute to the correct delimitation of our endemic genera. Using updated databases and bibliographic sources, an exhaustive revision of these genera was carried out. Genera with registries outside of the country, as well as those that had enough evidence to change their taxonomic status were subtracted from the list. A critical revision of the systematic bibliography available is provided, emphasizing the discussion on those genera with ambiguous classification status.
