Castilleja ornata
Castilleja subinclusa
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.

Varieties 3 (3 in the flora).
Castilleja subinclusa is divided into three varieties with somewhat discontinuous ranges. Identification of the varieties is often difficult when comparing only a single trait but is more easily accomplished when the characters are considered in a suite. The three varieties are also separable by range and habitat.
