Castilleja integra
(Wholeleaf Paintbrush)
Family: Scrophulariaceae (Figwort)
   
Castilleja integra is the only orange paintbrush found on the plains. C. integra also grows on the lower foothills. The orange parts of the plants are leafy bracts, not the flowers. The common name "wholeleaf" refers to the lack of lobes on the leaves and bracts.

Compare to Castilleja linariifolia, which is sometimes found in the foothills but does not extend onto the plains.
Castilleja linariifolia has narrow, lobed leaves and the plants usually have a taller, more slender growth habit.
