Castilleja rubida
Castilleja scabrida
Castilleja rubida is a rare alpine species endemic to a few limestone peaks in the Wallowa Mountains of northeastern Oregon, entirely within the Eagle Cap Wilderness Area. It is likely derived from the C. nana complex, found in the mountains of eastern California and Nevada, but it is amply distinct. Due to its very limited range and small population numbers, C. rubida is a species of conservation concern.

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.
