Castilleja citrina
Castilleja praeterita
Although the range of Castilleja citrina overlaps the range of its close relatives, C. lindheimeri and C. purpurea, in central Texas, C. citrina extends considerably farther to the west and northwest of the others (G. L. Nesom and J. M. Egger 2014). The inflorescences of C. citrina are mostly pale to bright lemon yellow or occasionally brassy yellow. The color and usually more elongate abaxial corolla lip separate it from C. lindheimeri and C. purpurea. Castilleja citrina is similar to some color forms of C. sessiliflora, but the more conspicuously curved corolla of C. sessiliflora is usually exserted far above the calyx and is often white to pale pink, rather than yellow.

Castilleja praeterita is endemic to subalpine, sagebrush-dominated meadows in the southeastern Sierra Nevada of Inyo and Tulare counties. It is closely associated with and likely parasitic on Artemisia rothrockii. Inflorescence coloration varies by population, with some having only yellow-bracted plants, while others are pale orange to pale red with occasional pale yellow variants. Yet other populations have only pale salmon-colored bracts.
