|discussion=<p><i>Castilleja xanthotricha</i> is endemic to moderate elevations in the sagebrush hills of the John Day River drainage in north-central Oregon. N. H. Holmgren (1971) hypothesized that this tetraploid species is of allopolyploid hybrid origin between <i>C. glandulifera</i> and <i>C. oresbia</i>.</p>
