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 kerryana is endemic to alpine peaks and ridges around the Scapegoat Plateau of Lewis and Clark County, in the eastern Rocky Mountains of central-western Montana. It is closely associated with and probably parasitic on Dryas hookeriana. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
