S. nutalli: https://www.inaturalist.org/observations/127673470
S. rubella: https://www.inaturalist.org/observations/129545588

leaves 3-10 mm, 3-veined - rubella
leaves 5-20 mm, 1-veined - nutallii
(veins very hard to see in photos)

rubella sepals are smaller and come to a point but not tapered point
sepals 2.5-3.5 mm, acute (not spinescent) - rubella
sepals 3.5-6 mm (nearly as long as petals), acuminate to spinescent - nutallii

alpine - more likely rubella
sagebrush hills, nutallii
both may be subalpine

both extensively glandular to hairy
