Notes.
A few specimens from arid area (e.g., W.A.) appear annual. This species usually
has longer lemma awns than other Elymus species in Australia, and
probably was referred to "long-awned" form of Elymus scaber
complex by some workers.
Usually grows in open
area along road, on grassy hillside and burnt ground, or on flood plain of
rivers.
