The plant was first described in 1856 as Podophorus bromoides, and placed in the monotypic genus Podophorus. A genetic analysis of the type material found it to be most closely related to Megalachne, also endemic to the Juan Fernández archipelago. This clade was in turn found to be nested within a paraphyletic Festuca, most closely related to F. pampeana of South America.{{Cite journal|last1=Moreno-Aguilar|first1=María Fernanda|last2=Arnelas|first2=Itziar|last3=Sánchez-Rodríguez|first3=Aminael|last4=Viruel|first4=Juan|last5=Catalán|first5=Pilar|date=2020-06-26|title=Museomics Unveil the Phylogeny and Biogeography of the Neglected Juan Fernandez Archipelago Megalachne and Podophorus Endemic Grasses and Their Connection With Relict Pampean-Ventanian Fescues|journal=Frontiers in Plant Science|volume=11|pages=819|doi=10.3389/fpls.2020.00819|issn=1664-462X|pmc=7333454|pmid=32754167|doi-access=free}} In 2020 it was placed in the genus Festuca as F. masatierrae.
