 shorter hairs ; floral glume short-owned, as long as the palea. 



Magell. ; Fuegia ; S. Patagon. by Rivers Gallegos and Sta. Cruz. 



"Handsome, but my (Fuegian) specimens have a small truncate, not 



ovate, ligule." (Speg.)

 shorter than the culm, which is sheathed to its middle ; ligule rather long,
