Habit | Herbs, perennial, 0.7–2 dm; from a woody caudex; with a taproot. | |
Stems | few to many, spreading to ascending, unbranched except for short, leafy shoots in axils of leaves, glabrate to distally puberulent, hairs sparse to dense, spreading, ± short, soft, sometimes stipitate-glandular. |
|
Leaves | green to purple, linear or narrowly lanceolate to narrowly oblong, (1.1–)2–8 cm, not fleshy, margins plane, involute, (0–)3–7(–9)-lobed, apex acute to obtuse; lobes spreading, linear to narrowly lanceolate, apex acuminate. |
|
Inflorescences | 2.5–5.5 × 1.5–2.5 cm; bracts rose purple, magenta, lilac, or crimson throughout, or proximally greenish to dull purplish, distally as above, lanceolate to ovate or broadly elliptic, 3–7(–13)-lobed; lobes spreading to erect, linear to narrowly lanceolate, long or short, proximal arising below mid length, central lobe apex rounded to acute, lateral ones acute. |
|
Corollas | straight or slightly curved, 20–25 mm; tube 13–15 mm; beak exserted, sometimes part of abaxial lip equal to or exceeding calyx; beak adaxially green, 6–8 mm; abaxial lip greenish at base, becoming white to rose pink on apices, reduced, slightly pouched, 2–3 mm, 33–50% as long as beak; teeth ascending, white, pink, or green, 1–2.2 mm. |
|
Calyces | colored as bracts, 12–26 mm; abaxial and adaxial clefts 5–10 mm, 50% of calyx length, deeper than laterals, lateral 0.2–6 mm, 25% of calyx length; lobes triangular, apex acute. |

Discussion | 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).

Castilleja haydenii is endemic to high-elevation slopes in the Rocky Mountains of southern Colorado and northern New Mexico. It is known in Utah from a single collection from high elevations in the La Sal Mountains. Reports of this species elsewhere are usually attributable to C. rhexiifolia. Its affinities are uncertain. Some features are shared with C. rhexiifolia, but in other ways it resembles species such as C. lemmonii of the Sierra Nevada. Plants in the northwestern portions of its range tend to have less divided leaves. Castilleja haydenii occasionally hybridizes with C. occidentalis where the two commingle in the lower alpine zone.
