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. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Castilleja collegiorum is endemic to a large meadow system in the southern Cascade Range of Klamath County. It is similar to C. cryptantha in Washington and C. lemmonii in California but differs from both in structural details of the inflorescence, calyx, bracts, and leaves.
