Elevation: 2200–3000 m.

Discussion

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.
