Tasmania 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. |
