Biology: This species has been confused with D, caespirosa and the apparent difference in lemma size may not be satisfactory. The relative and overall lengths of the flat part and awn of the lateral lobe, and the length of the collar hairs are helpful in distinguishing the two species.

Uses: Of considerable importance as a pasture grass.
