|discussion=<p><i>Eriogonum brachypodum</i> is variable in overall shape, peduncle length, and shape and size of involucres and flowers. Spreading plants with longish peduncles and narrow involucres occur in southwestern Utah and adjacent portions of <i>Nevada</i> and Arizona; this is the “parryi” phase of the species. Typical <i>E. brachypodum</i> is low and flat-topped, with the inflorescence up to 10 dm across. The involucres are usually sessile and campanulate rather than turbinate. The two phases intergrade completely and a taxonomic distinction is not warranted. Dried plants of the typical phase often are used as decorations.</p><!--
--><p>The species is common and even weedy in places. It occurs from Churchill and Pershing counties, <i>Nevada</i>, south through Mono and Inyo counties to eastern Kern and San Bernardino counties, California, then eastward through <i>Nevada</i> (Clark, Esmeralda, Lincoln, Mineral, and Nye counties) into southwestern Utah (Beaver and Washington counties) and northwestern Arizona (Mohave County). It is much more common in the Mojave Desert than in the Great Basin.</p>
