Avena barbata is a species of wild oat known by the common name slender wild oat. It has edible seeds. It is a diploidized autotetraploid grass (2n=4x=28).Its diploid ancestors are A. hirtula Lag. and A. wiestii Steud (2n=2x=14), which are considered Mediterranean and desert ecotypes, respectively, comprising a single species.
