Discussion | Variety steenensis is endemic to the upper elevations of Steens Mountain in Harney County. It appears distinct when seen in its dwarfed form on the highest slopes; some transitional plants exist at lower elevations where it encounters var. pilosa. Genetic studies of this complex are in progress. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
