has five introduced species of oats, Avena. These
are large erect annuals. The distinctive features of this
genus include the open panicles of large (>15mm long
excluding the awns), multiple-flowered spikelets with glumes
are longer than the florets, and usually long awns on the
backs of the lemmas.
It can be confused with
Arrhenatherum (onion twitch), which has
smaller spikelets and bulbs at the base of the stem.
Avena strigosa is bristle oat.
