Presence of the hybrid x Agropogon littoralis (Gramineae: Agrostideae) in Chile

Abstract

x Agropogon littoralis (Sm.) C. E. Hubb., originally described as a natural hybrid between Agrostis stolonifera L. and Polypogon monspeliensis Desf., is reported for the first time for Chile and America. This taxon is described and illustrated and the geographical distribution is included. The differences with the related species are mentioned. It should not be discarded that one of the parental species of the chilean hybrid could be P. australis Brongn.
