Habit | Herbs, perennial, 0.8–3.1 dm; from a woody caudex; with a taproot. | Herbs, perennial, 0.7–2.6 dm; from a many-headed, short, woody caudex; with a taproot. |
Stems | several to many, erect to ascending, unbranched, sometimes branched near base, hairs spreading, long, soft, eglandular, mixed with dense, short stipitate-glandular ones. |
few, ascending, unbranched, sometimes branched, glabrate to sparsely hairy proximally, becoming densely hairy distally, proximal hairs appressed, white, short, soft, eglandular, distal hairs widely spreading to erect, white or yellowish, long to very long, soft, eglandular. |
Leaves | green, narrowly to broadly lanceolate or oblong-lanceolate, 9–35 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, distal sometimes 3-lobed, apex narrowly acuminate; lobes ascending or spreading, linear to lanceolate, apex acute to obtuse. |
green to sometimes red-brown or dull purplish, linear to linear-lanceolate, 1.5–4 cm, not fleshy, margins plane, sometimes ± wavy, involute, (0–)3(–5)-lobed, apex acute to acuminate; lobes linear or linear-lanceolate, laterals ± divaricate, often abruptly up-curved from plane of main leaf blade, proximals usually 33–50% as long as leaf, apex acuminate to acute. |
Inflorescences | 3–9(–18) × 2–3 cm; bracts green to pale green to rarely dull purplish brown throughout, distally rarely with pale yellow apices, narrowly lanceolate to narrowly elliptic to sometimes broadly lanceolate, 3-lobed, wavy-margined; lobes spreading or ascending, narrowly lanceolate, medium length, arising at or above mid length, sometimes wavy-margined, apex obtuse to acute. |
2–11 × 1–2.5 cm; bracts greenish or pale yellow, rarely purplish or deep red, often with dull purplish veins on proximal bracts, or proximally greenish or pale yellow, distally whitish, yellow, or orange-yellow, proximal sometimes linear-lanceolate, distal broadly lanceolate to oblong or obovate, (0–)3–5(–7)-lobed; lobes ascending to erect, linear to lanceolate, short to medium length, arising above mid length, proximal bract apex acute, distal obtuse, rounded, or truncate. |
Corollas | conspicuously decurved distally, 18–22 mm; tube 11–14 mm; beak exserted, adaxially green to yellow-green or yellow, 6–8 mm; abaxial lip green, reduced, fleshy, included, 1.5–2 mm, 25% as long as beak, sparsely hairy, hairs spreading; teeth ascending, green, 0.5–1 mm. |
slightly curved, 10–22 mm; tube 8–14 mm; teeth of abaxial lip sometimes slightly exserted, beak exserted or subequal; beak adaxially green to pale yellow, 5–8 mm; abaxial lip deep yellow or green, reduced, forming a small pouch visible through front cleft, 3–5 mm, 50–75% as long as beak; teeth ascending to erect, white or yellow, 1 mm. |
Calyces | green or yellowish green, 15–19 mm; abaxial and adaxial clefts 9–11 mm, 60% of calyx length, deeper than laterals, lateral 3.5–7 mm, 15–25% of calyx length; lobes broadly or narrowly triangular, taller than wide, apex acute to obtuse. |
colored as bracts, proximally often paler, usually yellow throughout, 10–20 mm; abaxial and adaxial clefts 7–14 mm, 40–50% of calyx length, deeper than laterals, lateral 0.5–1.5 mm, 5–15% of calyx length; lobes triangular, apex acute to rounded. |

Discussion | Castilleja chlorotica is an uncommon to rare endemic on dry slopes in Deschutes, Klamath, Lake, and possibly Crook counties in central Oregon. The hooked corolla beak and greenish bracts, often aging purplish distally, help distinguish it from similar species such as C. glandulifera and yellow forms of C. applegatei var. pinetorum.

Castilleja hyperborea is widespread across boreal, alpine, and arctic habitats in western Canada and Alaska, extending into the Russian Far East. A rare form with light purple bracts was named as C. kuschei. Another form with particularly long hairs found in the Kluane Lake region of the southern Yukon was described as C. villosissima and is usually found on calcareous substrates.
