--><span class="statement" id="st-undefined" data-properties=""><b>Plants </b>perennial or annual; rhizomatous or cespitose, rhizomes often extensively branched. <b>Culms</b> 5-200 cm, erect or decumbent, often rooting at the lower nodes, sometimes branched above the base; nodes often pubescent. <b>Leaves</b> not basally concentrated; sheaths open, margins overlapping, not fused; auricles absent; ligules membranous, entire, toothed, or ciliate; blades flat or convolute, often attenuate. <b>Inflorescences</b> spikelike racemes, most or all nodes with 1 spikelet, sometimes some with 2-3, most or all spikelets appressed to strongly ascending; disarticulation above the glumes, beneath the florets. <b>Spikelets</b> 14-80 mm, terete to laterally compressed, with (3)5-24 florets. <b>Glumes</b> unequal, 1/2 as long as to equaling the adjacent lemmas, lanceolate, membranous, apices obtuse to acuminate, lower glumes 3-7-veined, upper glumes 5-9-veined; lemmas usually membranous, sometimes coriaceous at maturity, rounded on the back, (5)7-9-veined, apices obtuse or acute, unawned or terminally awned; paleas shorter than to slightly longer than the lemmas, with 2 well-developed veins, sometimes with minor veins in between, keeled over the well-developed veins, keels strongly ciliate; lodicules 2, oblong, attenuate distally, margins ciliate or apices puberulent; anthers 3; styles 2, free to the base, white. <b>Caryopses</b> oblong, flattened, apices pubescent; hila linear, x = 5,7, 9.</span><!--

|discussion=<p><i>Brachypodium</i> is a genus of about 18 species, with about 15 species in Eurasia, centered on the Mediterranean, and three in the Western Hemisphere, centered in Mexico. All five species in the Flora region are Eurasian. Four of the five species have been used in the western United States in seeding trials for mountain rangeland.</p>
