Habit | Herbs or subshrubs, perennial, 2–6 dm; from a woody caudex and sometimes from a woody proximal stem; with a taproot. | Herbs, perennial, (1.5–)2–4 dm; from a woody caudex; with branched, woody roots. |
Stems | many, spreading to erect, much-branched, with numerous short, leafy axillary shoots, hairs moderately dense, spreading, medium length to long, stiff to soft, shorter stipitate-glandular ones. |
few or several, ascending to erect, branched or unbranched, shiny proximally, glabrous proximally, hairy distally, hairs spreading, long, soft, eglandular, sometimes sparsely glandular. |
Leaves | gray-green becoming ± purple to sometimes green as hairs are lost, oblong to lanceolate-oblong or broadly lanceolate, 0.5–2 cm, ± fleshy, cupulate, sometimes obscurely so on distal portion of stem, margins plane, sometimes ± wavy, involute, 0–3-lobed, apex truncate or broadly rounded to obtuse; lobes erect to ascending, oblong, apex rounded. |
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. |
Inflorescences | 2.5–20 × 1.5–5 cm; bracts proximally green to dull, deep brownish purple, distally bright red, red-orange, or orange, sometimes yellow to yellow-orange, oblong or broadly lanceolate to widely obovate or ovate, often cup-shaped, center lobe often expanded distally, 0–3(–5)-lobed, often wavy-margined; lobes ascending, oblong, short or long, arising near or above mid length, central lobe apex mostly rounded to truncate, sometimes with 5 or so very shallow teeth. |
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 | slightly curved, 19–30 mm; tube 8.5–15 mm; beak exserted, adaxially green, 8.5–15 mm; abaxial lip ascending, deep green, reduced, 0.5–1 mm, 5–10% as long as beak; teeth incurved, reduced, green or white, 0.2–0.5 mm. |
straight to slightly curved, 20–37 mm; tube 12–21 mm; abaxial lip sometimes exserted, beak exserted; beak adaxially green, 10–16 mm; abaxial lip green, sometimes yellow, usually reduced, protruding through abaxial cleft, sometimes a little pouched, 3-lobed, 2–6 mm, 17–45% as long as beak; teeth erect, green, whitish, or yellow, 1–1.5 mm. |
Calyces | proximally light green to sometimes purple, distally colored as bracts, 15–25 mm; abaxial and adaxial clefts 6–9.5 mm, 33–50% of calyx length, deeper than laterals, lateral 1–3 mm, ca. 12% of calyx length; lobes broadly triangular to oblong, apex rounded to obtuse, rarely acute. |
colored as bracts, 18–28 mm; abaxial clefts 5–6 mm, adaxial 8–15 mm, clefts 28–50% of calyx length, deeper than laterals, lateral 1.5–6 mm, 5–25% of calyx length; lobes long-triangular, apex acute. |

Discussion | Castilleja latifolia is endemic to the central California coast, especially around Monterey Bay. Around Half Moon Bay in San Mateo County, it apparently forms hybrids with C. affinis var. affinis. Records of this species from north of San Francisco and south of Monterey County are referable to other species. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
