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.) |
Varieties 3 (3 in the flora). Castilleja pilosa is a widespread and variable complex similar in growth form and coloration to C. pallescens and related species. However, C. pilosa is distinguished with relative ease by its subequally divided calyces. Plants of the C. pallescens complex have very shallow lateral calyx lobes.
