Biology:Megalachne

From HandWiki

Megalachne is a genus of Chilean plants in the grass family, found only on the Juan Fernández Islands in the Pacific Ocean, part of the Republic of Chile.[1][2][3][4] It contains a single species, Megalachne berteroniana.[5]

A genetic analysis found it to be most closely related to the extinct Podophorus, 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.[6]

Several species formerly included in genus Megalachne are now considered synonyms of species placed in other genera:

  • Megalachne dantonii Penneck. & Gl.Rojas – synonym of Festuca dolichathera Röser & Tkach[7]
  • Megalachne masafuerana (Skottsb. & Pilg.) Matthei – synonym of Festuca masafuerana (Skottsb. & Pilg.) Röser & Tkach[8]
  • Megalachne robinsoniana C.M.Peña – synonym of Festuca robinsoniana (C.M.Peña) Röser & Tkach[9]
  • Megalachne zeylanica Thwaites - synonym of Eriachne triseta Nees ex Steud.[10]
