Discussion

Varieties 2 (2 in the flora).

Castilleja scabrida consists of two varieties distinguished by range and habitat differences, as well as by the morphological characters of the key. Both varieties are often confused with the similar and broadly sympatric C. chromosa but can be differentiated from the latter most easily by the presence of scalelike vestigial leaves on the proximal stems of C. scabrida.

Variety barnebyana grows on limestone substrates in the mountains of eastern Nevada and western Utah. It is frequently parasitic on Petrophyton caespitosum, a mat-forming plant from which the stems of the Castilleja often emerge, though the relationship is not obligate.
