Discussion

A few pink- to blue-purple-flowered populations of what would otherwise be var. nevadensis occur on the east slopes of the Cascade Range in central Washington (Chelan County). In morphology, these populations are similar to var. parkeri and clearly indicate a connection between var. parkeri to the east and the lanceolatus race of var. nevadensis to the west.
