Herbs, perennial, 1.5–5(–8) dm; from a woody caudex; with a taproot. Stems several to many, erect or ascending, sometimes curved at base, unbranched or branched, sometimes with short, leafy axillary shoots, hairs spreading, short or long and distally short, stiff or soft, stipitate-glandular. Leaves green to sometimes purple, narrowly oblong or lanceolate to sometimes linear or narrowly ovate, (0.8–)1–5(–6.5) cm, not fleshy, margins wavy, flat or involute, 0–5-lobed, apex rounded or obtuse, rarely acute; lobes ascending-spreading or divaricate, linear to narrowly oblong, apex acute. Inflorescences 2.5–25 × 1.5–4 cm; bracts proximally greenish, distally red, orange-red, or pale orange, rarely yellow, lanceolate or broadly lanceolate to oblong, (0–)3–5(–7)-lobed, plus 1–3 shallow teeth on apex of central lobe (var. clokeyi); lobes ascending or spreading, linear, lanceolate, or oblanceolate, medium length or long, arising at or near mid length, central lobe apex obtuse to rounded, lateral ones acute. Calyces proximally pale green, green, or whitish, sometimes with a yellow central band, distally colored as bracts, 14–26(–28) mm; abaxial and adaxial clefts 3–10 mm, 20–50% of calyx length, deeper than laterals, lateral 1–5 mm, 15–20% of calyx length; lobes lanceolate to broadly lanceolate, oblong, or ovate, apex acute, obtuse, or rounded. Corollas straight to slightly curved, (19–)22–45 mm; tube 11–22 mm; abaxial lip rarely exserted, beak exserted; beak adaxially green to yellowish, 9–21(–23) mm; abaxial lip green or deep green with white teeth or red with green teeth, reduced, not inflated, often visible through front cleft, 1–2 mm, ca. 10% as long as beak; teeth incurved, green to white, 0.5–1 mm. 2n = 24, 48, 72.

Discussion

Castilleja martini is sometimes treated as a subspecies of C. applegatei, but there are relatively consistent morphological discontinuities between these two variable complexes. See notes under 4. C. applegatei.
