Taxonomic notes:
Specimens with awned lemmas have been given the name of Bromus stamineus Desv. in C. Gay, Hist. fis. pol. Chile (Flor. Chile) 6:440 (1854) use of the name being followed by J. H. Willis (1970), A handbook to plants in Victoria. However the single character is variable and spikelets without awns often occur on the same plant as those with awns of variable length.
