Castilleja rubida
Castilleja brevistyla
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.

Castilleja brevistyla is endemic to the foothills of the southern Sierra Nevada and the southern reaches of the Inner South Coast Ranges, in Kern and adjacent counties. It often grows with other annuals, including C. attenuata, C. densiflora, and C. exserta. The similar C. attenuata has three-lobed bracts and leaves, while C. brevistyla has mostly five-lobed parts, and also differs in corolla structure and spotting. Hybrids between C. brevistyla and C. exserta are known from Kern County.
