**5.2.1 Aristidoideae Caro**

In Chile, only the genus *Aristida* is present, with three native species. Genus *Aristida* is distributed from Arica and Parinacota (ca. 18°S) to Araucanía (Malleco, 37°50'S). *Aristida adscensionis* is found in northern-central Chile (approx. 18°S-33°S), and *A. pallens* and *A. spegazzinii* in central-southern Chile (approx. 35-37°S). It has been established (Matthei, 1987) that *A. longiseta* previously cited for Chile (Marticorena & Quezada, 1985) is absent in Chile.
