One species, <i>B. tandilense</i>, is now established in California. None of the species is important for forage. Four of the five species are annual. The stout hygroscopic awn, apical awnlike teeth, and lemma pilosity all aid in its dispersal.</p><!-- --><p><i>Bromidium</i> is similar to <i>Agrostis</i>, and is sometimes included in it. It differs from <i>Agrostis</i> in its combination of dense, contracted, spikelike panicles with a relatively large number of spikelets, unawned glumes, and 4-awned or -toothed lemmas.</p> |tables= |references={{Treatment/Reference |id=rugolo1982a |text=Rugolo de Agrasar, Z.E. 1982.
