Habit | Herbs, perennial, (0.8–)1–2(–3) dm; from a woody caudex; with a taproot. | |
Stems | many, decumbent to ascending, unbranched, sparsely pubescent, hairs spreading, wavy, fairly short, soft, eglandular, sometimes glabrous proximally. |
|
Leaves | purple to green, narrowly, rarely broadly, lanceolate, 1.4–4 cm, not fleshy, margins plane, flat to involute, (0–)3–5(–7)-lobed, apex acute to acuminate; lobes divergent, spreading-ascending, linear, long, not much narrower than mid blade, often with secondary lobes, creating little frilly fans, apex acute or obtuse. |
|
Inflorescences | 2–6 × 2–3.5 cm; bracts proximally greenish or deep purple near base, distally red, scarlet, or crimson to red-orange, rarely orange, salmon, pink, or yellowish white, ovate to orbicular in outline, 5(–9)-lobed; lobes spreading, linear to linear-lanceolate, long, arising below mid length, apex acute to rounded. |
|
Corollas | straight or slightly curved, 25–35(–45) mm; tube 9–15 mm; beak exserted, adaxially green, purplish, or yellow-green, 14–22 mm; abaxial lip deep green, reduced, 0.5–2 mm, 6–12% as long as beak; teeth incurved to erect, green, 0.5 mm. |

Calyces | proximally purple, green, or whitish, distally colored as bract lobes, 15–25 mm; abaxial and adaxial clefts 8 mm, ca. 40–50% of calyx length, deeper than laterals, lateral 1–5 mm, 10–20% of calyx length; lobes triangular, apex obtuse or acute. |

Discussion | Castilleja rupicola is usually found in the subalpine and lower alpine zones in the Cascade Range from extreme southern British Columbia south to northern Douglas County, Oregon. Though it can be numerous where it occurs, the species as a whole is uncommon. One atypical population occurs in a moist, shaded, mossy, north-facing ravine on the Oregon side of the Columbia River Gorge, at less than 250 m. These plants often bear secondary divisions on deeply dissected leaves and bracts. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Varieties 3 (1 in the flora). Castilleja tenuiflora is common and widespread across the mountains of Mexico, especially in pine-oak-madrone communities at middle elevations, as far south as Oaxaca, where it is found west and north of the Tehuantepec lowlands. There are two varieties of C. tenuiflora endemic to Mexico, while the typical variety crosses into the mountains of southeast Arizona and southwest New Mexico. Considerable local and regional variation exists in C. tenuiflora, but most of this appears to be racial in nature, and additional named varieties are likely not justified. While also commonly herbaceous, C. tenuiflora often forms large, multi-stemmed, subshrub plants with a woody base and ascending to strongly erect and often branched stems. It is valued in Mexican traditional medicine and is under study for potentially useful compounds (M. Jiménez et al. 1995; P. M. Sanchez et al. 2013).
