Cognized, it would be best to treat them as a variety of P. secunda subsp. secunda, but this is not proposed here because it would only cause confusion selecting the correct name at the varietal rank among the many synonyms for this taxon. For this species Gould and Moran (1981) cite Isla Guadalupe as a location, possibly based on R.Moran 13816 (TAES) but this specimen is Koeleria pyramidata Lam.
