Castilleja integra (Paintbrush)
Scrophulariaceae (Snapdragon Family)

There are, according to Intermountain Flora, about 200 species of Castilleja; most grow in western North America, several in eastern North America and Asia, and about fifteen in Central and South America. 

The genus name, "Castilleja" honors Domingo Castillejo (1744-1793), Spanish botanist and Professor of Botany in Cadiz, Spain.  In the late 1770s Jose Celestino Mutis (who was born in Cadiz, Spain but spent most of his life in Columbia) named a new Columbian genus, Castilleja.  He sent the new specimen to Linnaeus' son who published it in Supplementum Plantarum in 1781.
