|discussion=<p><i>Castilleja chromosa</i> is sometimes confused with 3b. <i>C. angustifolia </i>var.<i> dubia</i> (see discussion there). <i>Castilleja chromosa</i> retains its distinctive morphology across its wide range and is a characteristic species of much of the southwestern United States. Where it overlaps with <i>C. angustifolia</i>, the two are distinguished by inflorescence color and width and by the lengths of the calyx, corolla, and corolla beak. In the broad region of their sympatry, there is little evidence of intergradation, except in a few sites in Elko County, <i>Nevada</i>, and in southern Wyoming. Throughout southern Idaho and northeastern <i>Nevada</i> the range of the two overlap with little or no intergradation. At high elevations in Montrose County, Colorado, <i>C. chromosa</i> has narrower leaves and a longer and silkier pubescence, especially in the inflorescence. Apparent hybrids between <i>C. chromosa</i> and <i>C. flava </i>var.<i> rustica</i> are known from Custer County, Idaho, and hybrids with <i>C. linariifolia</i> are known from Montrose County, Colorado.</p>
