Habit | Herbs, annual, 1.5–4.5 dm; with fibrous roots. | Herbs or subshrubs, perennial, 2.7–8 dm; from a small, woody caudex; with thick, woody roots. |
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 sprawling, usually profusely branched, including many small, leafy axillary shoots, hairs dense, retrorse, medium length, stiff, eglandular, distally spreading, long, soft, sometimes matted, very short-glandular. |
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, linear-lanceolate, distally sometimes broadly lanceolate, 2–4.5 cm on main branch, 0.5–1 cm on proximal part of side branches, not fleshy, margins plane, involute, sometimes flat, 0-lobed, apex acute to acuminate. |
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. |
2–4.5(–14 in fruit) × 1.5–4 cm; bracts proximally greenish, distally red to reddish orange, broadly lanceolate to oblong, 0(–3)-lobed; lobes ascending, lanceolate, short, arising above mid length, apex acute to obtuse. |
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. |
slightly curved, 15–24 mm; tube 10–13 mm; beak exserted, adaxially green, 6–10 mm; abaxial lip green, reduced, slightly pouched, sometimes visible in front cleft, 0.5–1.5 mm, 15–20% as long as beak; teeth incurved, white or green, 0.4–0.7 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. |
proximally pale green to pale yellow-green, distally pale red to red-orange above middle, 12.5–20.5 mm; abaxial and adaxial clefts 6–9 mm, 33–50% of calyx length, deeper than laterals, lateral (1.5–)3–4 mm, 20–35% of calyx length; lobes lanceolate or broadly triangular, apex acute. |
Filaments | glabrous. |

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 organorum is endemic to the Organ Mountains of Doña Ana County. Reports from the mountains of the Mogollon Rim of east-central Arizona and adjacent New Mexico are based on specimens of C. nelsonii. Castilleja organorum is grouped with C. linariifolia by some authors (for example, G. L. Nesom 1992c), but it has subequal abaxial and adaxial calyx clefts and is more likely closely related to C. integra. Castilleja organorum differs from the latter species in its loose, often profusely branched habit, more compact inflorescences, and usually smaller corollas. In Fillmore Canyon, C. integra, C. lanata, and C. organorum are all found, but each is in a different habitat, and there is no sign of hybridization.
