Notes on the genus Ophryosporus (Asteraceae, Eupatorieae) in Chile.

Ophryosporus Meyen is reviewed for Chile and an updated species list for the country based on herbarium records and literature review is presented. A key to the Chilean species is provided and a distribution range of taxa is indicated based on herbarium records and our own collections. We include several lectotypifications as well as an epitypification of Ophryosporus hoppii. The presence of two species, O. hoppii and O. floribundus, formerly accepted for Chile, is questioned and their actual distribution discussed.
