Castilleja viscidula
Castilleja ornata
Castilleja viscidula is a member of the complex including C. applegatei and C. martini, centered in California. Castilleja viscidula favors isolated mountain ranges, from the Wallowa and, possibly, the Blue mountains of northeastern Oregon, eastward into southwestern Idaho, and southward into central Nevada. Most populations are greenish yellow, but in one portion of the Wallowa Mountains, reddish bracted plants are common. Many yellowish bracted populations in the same mountain range surround this reddish population. Intermediate color forms are rarely encountered. Most ranges where C. viscidula occurs have generated slightly differing local races, demonstrating some reproductive isolation and divergence. In addition, hybrid swarms between this species and C. nana are known from several mountain ranges in central and northern Nevada, and an apparent hybrid with C. flava var. flava is known from the Independence Mountains of northern Nevada.

Castilleja ornata is known from Chihuahua and northern Durango, Mexico, but much of its seasonally moist grassland habitat is now altered by grazing or agriculture, and there are no recent sightings of the species south of the United States border. There is a recently discovered population in southwestern New Mexico, in the southern Animas Valley of Hidalgo County. While very rare, C. ornata lacks federal protection. The small Animas Valley population is the last known extant occurrence, and this population was reduced to two individuals in a census conducted in 2017 (D. Roth, pers. comm.). The species appears to be critically endangered globally and in need of conservation management.
The inflorescences of Castilleja ornata have pale greenish bracts with white apices when young, but the apices often become pale pink to dull reddish with age. Its pubescence, wavy-margined leaves, and unusual bract color also distinguish C. ornata. Castilleja exserta and C. minor are the only other annual paintbrushes in New Mexico and differ from C. ornata by the color of their floral bract apices, which are usually pink to red-purple in C. exserta and bright red in C. minor.
