Habit | Herbs, perennial, 1–4 dm; from a woody caudex; with a taproot. | Herbs, perennial, (1.5–)2–4 dm; from a woody caudex; with branched, woody roots. |
Stems | few to many, erect or strongly ascending, unbranched except for small, leafy axillary shoots, hairs spreading-reflexed to ± appressed, matted, long, soft, with much shorter stipitate-glandular ones, white-woolly. |

Leaves | 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. |
deep purple to green, linear-lanceolate to narrowly lanceolate, rarely broadly lanceolate, 1.5–4.5 cm, not fleshy, margins plane, flat or slightly involute, 0(–3)-lobed, apex usually acuminate or acute; lobes upright or ascending, lanceolate, apex acute. |

2–12 × 2–6 cm; bracts deep reddish or crimson, rarely magenta or dull orange, or proximally greenish near base, distally colored as above, oblong to broadly lanceolate, often spreading from base and exposing calyces, 0–3(–5)-lobed; lobes ascending to erect, linear, short to medium length, arising near or above mid length, apex acute to obtuse. |
Corollas | 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. |

Calyces | 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. |

Discussion | 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 purpurascens is a species of gravelly flood plains and riverbanks at moderate elevations in the vicinity of the Kicking Horse River in Yoho National Park, British Columbia, and in immediately adjacent Alberta. While this tetraploid species may be derived from hybridization between C. miniata and C. rhexiifolia, its combination of traits is unique, and the species forms morphologically consistent populations limited to a habitat not particularly favored by either putative parent species. Very occasional hybrids are known with both C. lutescens and C. miniata. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
