green, linear to narrowly oblong or narrowly lanceolate, 1.3–5 cm, not fleshy, margins plane, sometimes wavy, involute, 3–7-lobed, apex acute;
lobes divergent, spreading-ascending, linear, apex acute to 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.
5–22 × 1–4.5 cm;
bracts green to yellow-green throughout, or proximally green to yellow-green, distally yellow to sometimes pale yellow-orange, narrowly lanceolate to narrowly oblong or broadly lanceolate, 3(–7)-lobed;
lobes ascending to spreading, linear to oblong, medium length to long, arising near or below mid length, central lobe apex rounded to obtuse, lateral ones acute.
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.
straight or slightly curved, 14–22 mm;
tube 7–14 mm;
beak tip barely exserted from calyx;
beak adaxially greenish, 4–7 mm;
abaxial lip green to yellow, reduced, 1–4 mm, usually less than 67% as long as beak;
teeth erect, white to yellow, 1–2.5 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.
colored as bracts, 15–20 mm;
abaxial and adaxial clefts 5.5–8 mm, 30–50% of calyx length, ± deeper than laterals, sometimes appearing subequal in pressed specimens, lateral 5–6 mm, ca. 33% of calyx length;
lobes linear to narrowly lanceolate, sometimes expanded towards apices, apex 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.

Castilleja lineata
Castilleja organorum
Castilleja lineata is restricted to the mountains of northeastern Arizona, southern Colorado, and northwestern New Mexico. It is uncommon throughout its range and is without apparent close relatives. The Navajo used C. lineata as a medicinal plant and for its sweet nectar (D. E. Moerman 1998).

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.
