Perennial Beard-grass is sometimes considered to be a sterile intergeneric hybrid between Polypogon monspeliensis and Agrostis stolonifera L. In Victoria it appears to be a fertile, true-breeding species and is treated as such here. It is an occasional component of saltmarshes and margins of brackish watercourses.
