Due to its geographic isolation, Chile is a biogeographic island which harbors a high percentage of endemism. More than 50% of the native vascular flora is endemic and more than 60% lives in Central Chile, included in the Chilean Biodiversity Hotspot. Endemic are species with a geographic distribution restricted to a single area and could be especially vulnerable. For these reasons, updated lists of endemic species are necessary. Based on a databases, the study of specimens from two Chilean

Seventy-one species (19.9% of the native grass species) were classified as endemic. Most species occur along the Chilean hotspot of biodiversity, mainly in the Mediterranean region of the hotspot. One species (Podophorus bromoides) is extinct, three species are critically endangered, two species are endangered, one species is vulnerable, and one species is near threatened. The conservation status of most species (89%) needs to be evaluated. Most of the threatened species are endemic to the Juan Fernández Archipelago.
