|discussion=<p><i>Xanthisma coloradoense</i> is mostly alpine, but sometimes present in foothills or on plains, scattered through the southern Rocky Mountains of Colorado and southern Wyoming.</p><!--
--><p><i>Xanthisma coloradoense</i> and <i>X. grindelioides</i> <i></i>var.<i> grindelioides</i> are known to hybridize in Carbon County, Wyoming, one of the few places where the two are sympatric. Several hybrid swarms have been detected in the vicinity of Wheatland Reservoir number 2.</p><!--
--><p>Two varieties of <i>Xanthisma coloradoense</i> were recognized by R. L. Hartman (1976, 1990). They were distinguished by size, shape, and serration of leaves, size of flowering heads, and ray corolla length. With the number of additional collections amassed, these distinctions no longer hold and the varieties are not recognized.</p>
