Habit | Herbs, perennial, (0.8–)1–2(–3) dm; from a woody caudex; with a taproot. | Herbs, annual, 1.7–3.5(–5) dm; with a thin taproot or fibrous root system. |
Stems | many, decumbent to ascending, unbranched, sparsely pubescent, hairs spreading, wavy, fairly short, soft, eglandular, sometimes glabrous proximally. |
solitary or few to several, erect or ascending, often branched low on stem, unbranched distally, hairs appressed or retrorse, medium length, soft, eglandular, mixed with shorter stipitate-glandular ones. |
Leaves | purple to green, narrowly, rarely broadly, lanceolate, 1.4–4 cm, not fleshy, margins plane, flat to involute, (0–)3–5(–7)-lobed, apex acute to acuminate; lobes divergent, spreading-ascending, linear, long, not much narrower than mid blade, often with secondary lobes, creating little frilly fans, apex acute or obtuse. |
green or purple-tinged, proximal forming a rosette, linear-lanceolate to oblong or oblanceolate, 2–4 cm, not fleshy, clasping, margins wavy, sometimes plane, involute, 0-lobed, apex acuminate, acute, or obtuse. |
Inflorescences | 2–6 × 2–3.5 cm; bracts proximally greenish or deep purple near base, distally red, scarlet, or crimson to red-orange, rarely orange, salmon, pink, or yellowish white, ovate to orbicular in outline, 5(–9)-lobed; lobes spreading, linear to linear-lanceolate, long, arising below mid length, apex acute to rounded. |
3–24 × 1.5–3 cm; bracts proximally green, distally white, sometimes very pale yellow, often aging dull pink or dull red-purple, spatulate, 0-lobed, sometimes seeming lobed due to wavy margins, apex obtuse to rounded. |
Corollas | straight or slightly curved, 25–35(–45) mm; tube 9–15 mm; beak exserted, adaxially green, purplish, or yellow-green, 14–22 mm; abaxial lip deep green, reduced, 0.5–2 mm, 6–12% as long as beak; teeth incurved to erect, green, 0.5 mm. |
slightly curved, 22–24 mm; tube 10–13 mm; beak exserted, adaxially green, 5–10 mm; abaxial lip pale greenish, reduced, pouches 3, 0.5–1.5 mm, 5–10% as long as beak; teeth slightly incurved, reduced, pale greenish to white, 0.3–0.7 mm. |
Calyces | proximally purple, green, or whitish, distally colored as bract lobes, 15–25 mm; abaxial and adaxial clefts 8 mm, ca. 40–50% of calyx length, deeper than laterals, lateral 1–5 mm, 10–20% of calyx length; lobes triangular, apex obtuse or acute. |
green throughout or distal margin white aging pink, 15–17 mm; abaxial and adaxial clefts 6–14 mm, 35–45% of calyx length, deeper than laterals, lateral 0(–0.7) mm, 0(–5)% of calyx length; lobes short-triangular, abaxial segments longer than adaxials, apex acute to obtuse or rounded. |

Discussion | Castilleja rupicola is usually found in the subalpine and lower alpine zones in the Cascade Range from extreme southern British Columbia south to northern Douglas County, Oregon. Though it can be numerous where it occurs, the species as a whole is uncommon. One atypical population occurs in a moist, shaded, mossy, north-facing ravine on the Oregon side of the Columbia River Gorge, at less than 250 m. These plants often bear secondary divisions on deeply dissected leaves and bracts. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.
