Habit | Herbs, perennial, 0.8–3.1 dm; from a woody caudex; with a taproot. | Subshrubs or herbs, perennial, 1.8–9(–10) dm; from a woody caudex; with a thick, woody taproot or system to thick, branched 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. |
few to many, erect to ascending, unbranched, sometimes branched distally, sometimes with leafy axillary shoots, lanate to woolly, hairs dense, spreading to weakly appressed, white to yellowish, medium length, soft, moderately branched or unbranched in different populations, sometimes mixed, eglandular, rarely short stipitate-glandular, mostly obscuring surface. |
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, often hidden by matted, white hairs, linear to narrowly oblong or narrowly lanceolate, (1–)2–7(–10) cm, not fleshy, margins plane, flat, sometimes involute, 0–3-lobed, apex rounded, sometimes acute; lobes spreading, linear or narrowly oblong, apex rounded 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. |
2–19 × 1.5–5 cm; bracts proximally pale greenish to greenish gray, distally bright red to orange-red, sometimes pinkish, magenta, or salmon, rarely yellow, oblong to narrowly lanceolate or narrowly oblanceolate, deeply 0–3(–5)-lobed; lobes spreading, oblanceolate or linear, long, arising below mid length, distal bract apex usually rounded. |
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. |
curved in proximal 1/3, 23–35(–42) mm; tube 12–17 mm; beak exserted, adaxially greenish to yellowish, 11–22 mm; abaxial lip dark green, reduced, 1–4 mm, ca. 20% as long as beak; teeth incurved, reduced, green, 0.5–2.5 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. |
proximally whitish to green, central band whitish, distal 1/3 colored as bract lobes, sometimes lighter or deeper, 15–29 mm; abaxial and adaxial clefts 6–14 mm, ca. 50% of calyx length, deeper than laterals, lateral 0–5 mm, 0–5(–15)% of calyx length; lobes oblong to broadly triangular, apex rounded, truncate, or emarginate. |

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.

Most records of Castilleja lanata are from the southern third of Arizona, New Mexico, and southwestern Texas. Plants sometimes referred to C. lanata from the Channel Islands of California are assigned here to C. hololeuca, an insular endemic. In northern Mexico, C. lanata extends from San Luis Potosí and Nuevo León westward to Sonora, with a disjunct distribution in central Baja California, where it overlaps the southern limits of a related species, C. foliolosa. Castilleja lanata inhabits a wide spectrum of soils and elevations and does not co-occur with the closely related C. galehintoniae in Nuevo León, where the latter is limited to limestone and gypsum substrates in a narrow elevational range. Hybrids of C. lanata with C. sessiliflora are known from Pecos County, Texas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
