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 praeterita is endemic to subalpine, sagebrush-dominated meadows in the southeastern Sierra Nevada of Inyo and Tulare counties. It is closely associated with and likely parasitic on Artemisia rothrockii. Inflorescence coloration varies by population, with some having only yellow-bracted plants, while others are pale orange to pale red with occasional pale yellow variants. Yet other populations have only pale salmon-colored bracts. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
