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 elegans is a characteristic species of the arctic and arctic-alpine regions. Its eastern and western limits are poorly understood, due to confusion with the similar species C. raupii to the east and south, and with C. rubra (Drobow) Rebristaya in eastern Asia. All three are part of a morphologically variable complex of recently evolved and poorly differentiated entities informally known as the C. pallida complex, after the first-described member of the group. Some reports of C. elegans in eastern Canada are here referred to C. septentrionalis. A recent collection of C. elegans from the northern Canadian Rocky Mountains is apparently disjunct, though it may also suggest its wider presence in Alberta.
