Stem leaves clasping with the largest ones midstem and are oval-shaped with pointed tips. Flowers are a well-spaced cluster that grows tighter towards the top. The flowers are blue or purple and are 1 to 1 1/2 inches long, with a short-haired staminode at the throat, and sparse hairy anthers inside.

This species is endemic to the Blue Mountains in southeastern Washington and northeastern Oregon. It reportedly grows in the following counties; Columbia (WA), Garfield (WA), Asotin (WA), Umatilla (OR), Union (OR), Wallowa (OR) and Grant (OR).[4] It is possible it also grows in Whitman County, Washington.

Habitat

Subalpine areas, usually on rocky soil on the east side of hills or mountains. Open forests, ridge tops and gravelly slopes.[6]

gollark: It's too far away to be very useful.
gollark: Consider the difficulty of having to collect then dispose of/recycle "spent" solar panels ~30 years after deployment.
gollark: One problem with solar/wind is that (like most things) they degrade over time (lithium ion batteries, which you could end up needing many of, especially fast), and would be in remote locations in huge quantities...
