Corolla beaks 4.5–6.5 mm; abaxial lip purple or pink, sometimes pale-yellow, distally sometimes white, 3.5–6 mm, 75–100% as long as beak; teeth white or pale-yellow.

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.
