Habit | Herbs, annual, 1.5–4.5 dm; with fibrous roots. | Herbs, perennial, 0.8–3.1 dm; from a woody caudex; with a taproot. |
Stems | solitary or few, erect, unbranched or branched, hairs spreading, short to long, ± stiff, mixed with short stipitate-glandular ones. |
several to many, erect to ascending, unbranched, sometimes branched near base, hairs spreading, long, soft, eglandular, mixed with dense, short stipitate-glandular ones. |
Leaves | green, linear to narrowly lanceolate or narrowly oblong, 2–5.7 cm, not fleshy, margins plane, flat, 3–7(–9)-lobed, apex acuminate to acute; lobes spreading to ascending, linear to narrowly oblong, apex acuminate. |
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. |
Inflorescences | 2–14 × 1–4 cm; bracts greenish throughout, or proximally greenish, distally white, cream, pale pink, or pale purple on apices, linear-lanceolate, 5–7(–9)-lobed, sometimes with secondary lobes; lobes ascending to spreading, linear to narrowly oblanceolate, long, arising all along leaf axis, apex acute to obtuse. |
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. |
Corollas | straight or slightly curved, 12–25 mm; tube 9–14 mm, expanded distally; abaxial lip sometimes slightly exserted, never hidden by slender calyx lobes, beak exserted; beak straight, adaxially white or lilac pink, 3–5.5 mm, inconspicuously puberulent; abaxial lip proximally white, distally yellow, with purple or red-brown spots, conspicuous, pouches 3, inflated, 4–6 mm, 4–5 mm wide, 2 mm deep, longer than deep, 1.5–4 mm, 90% as long as beak; teeth erect, white, usually with purple spot at base, 0.5–1 mm. |
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. |
Calyces | colored as bracts, 15–25 mm; all 4 clefts subequal, 7–11 mm, 50–67% of calyx length; lobes linear, apices often slightly expanded, apex obtuse to acute. |
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. |

Discussion | Castilleja lineariloba is endemic to the western slope of the Sierra Nevada. Its chromosome number is 2n = 20, an apparent aneuploid reduction and documented by numerous counts. This diploid number is shared only with two very distantly related annual species endemic to central Mexico, C. gracilis Bentham and C. tenuifolia M. Martens & Galeotti.

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.
