|discussion=<p><i>Castilleja sessiliflora</i> ranges across the Great Plains from southern Canada to northern Mexico, where it is apparently rare. In Texas and northern Mexico, its range overlaps with the similar <i>C. mexicana</i>. Most populations of <i>C. sessiliflora</i>, especially north of Texas, have white to pale yellow inflorescences; in southwestern Texas they are more variable in color, with pink-purple plants often predominating locally. Those plants with pink-purple inflorescences were named forma purpurina by F. W. Pennell. In the limestone deserts of southern New Mexico and southeastern Arizona, the inflorescences are often a pale pink-orange, but these are intermingled with more typical greenish white plants. Occasional hybrids between <i>C. angustifolia </i>var.<i> dubia</i> and <i>C. sessiliflora</i> are known from northeastern Wyoming.</p>
