Castilleja rubida
Castilleja peckiana
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.

When describing Castilleja peckiana, Pennell noted that its variation approached C. hispida on one hand and C. miniata on the other, and it is likely of allopolyploid derivation. L. R. Heckard (1968) found chromosome numbers of n = 36, 48, and ca. 60. He hypothesized that C. chromosa, C. hispida var. acuta, and C. miniata were likely involved in its ancestry, and possibly C. pruinosa as well. Heckard suggested subsequent introgression among the derived forms introduced further complexity. Though complex, these forms are self-perpetuating and appear morphologically stable within their range.
