Habit | Herbs, perennial, 0.8–3.1 dm; from a woody caudex; with a taproot. | Herbs, annual, 1–4.5 dm; with fibrous roots. |
Stems | several to many, erect to ascending, unbranched, sometimes branched near base, hairs spreading, long, soft, eglandular, mixed with dense, short stipitate-glandular ones. |
solitary, erect to ascending, unbranched, sometimes branched from base, hairs spreading, short and medium, ± stiff, 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 purple-tinged, linear to linear-lanceolate, (1–)2–8 cm, not fleshy, margins plane, flat, 0(–5)-lobed, apex acuminate; lobes spreading to ascending, filiform to lanceolate, apex sometimes acuminate. |
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. |
(1.5–)2–10(–19, –30 in fruit) × 1–2 cm; bracts proximally green to pale brown, rarely dull reddish brown, distally white on apices, sometimes pale yellow or pale pink-purplish on apices, rarely greenish or dull reddish brown throughout, lanceolate or lanceolate-elliptic, 3(–5)-lobed; lobes ascending, linear to lanceolate, long, arising below mid length, apex acuminate, acute, or obtuse. |
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. |
straight, 10–25 mm; tube 9–20 mm, not expanded distally; beak exserted, straight, adaxially white, light yellow, or greenish, 3–5 mm, inconspicuously puberulent; abaxial lip white or yellow with deep brown to purple spots, often becoming pink, slightly inflated, exserted or not, pouches 3, 2 mm wide, 1–1.5 mm deep, 3–4 mm, 75–80% as long as beak; teeth erect, white, pale yellow, or pink, 0.5–1.2 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, (8–)15–23 mm; abaxial and adaxial clefts (4–)6–8 mm, abaxial ca. 50% of calyx length, adaxial ca. 75% of calyx length, lateral 3–3.5 mm, 33% of calyx length; lobes linear to narrowly triangular, apex acute to acuminate. |

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 attenuata is a common and widespread species, ranging from southwestern Canada to northern Baja California, with several disjunct populations in central Chile. It is sensitive to competition from weeds. Disjunct populations in the Rincon Mountains in Pima County, Arizona, often have pink bracts but are otherwise typical.
