Habit | Herbs, perennial, 1–5 dm; from a branched, woody caudex; with a taproot. | Subshrubs or herbs, perennial, 1.8–9(–10) dm; from a woody caudex; with a thick, woody taproot or system to thick, branched roots. |
Stems | solitary or few, erect or ascending, unbranched, sometimes branched, hairs spreading, short, medium, and long, soft, short and medium ones short stipitate-glandular. |
few to many, erect to ascending, unbranched, sometimes branched distally, sometimes with leafy axillary shoots, lanate to woolly, hairs dense, spreading to weakly appressed, white to yellowish, medium length, soft, moderately branched or unbranched in different populations, sometimes mixed, eglandular, rarely short stipitate-glandular, mostly obscuring surface. |
Leaves | green or ± yellow, lanceolate, elliptic, or oblong to narrowly ovate, 1–2(–2.5) cm, not fleshy, margins plane or wavy, involute, (0–)3–5(–7)-lobed, apex rounded to acute; lobes ascending to erect, linear to lanceolate, apex rounded to acute. |
green to purple, often hidden by matted, white hairs, linear to narrowly oblong or narrowly lanceolate, (1–)2–7(–10) cm, not fleshy, margins plane, flat, sometimes involute, 0–3-lobed, apex rounded, sometimes acute; lobes spreading, linear or narrowly oblong, apex rounded to acute. |
Inflorescences | 3–20 × 2–3.5 cm; bracts proximally greenish to dull brown, distally red, orange-red, or scarlet, sometimes orange or yellow, broadly lanceolate or oblong, (0–)3–5-lobed; lobes ascending, broadly to narrowly lanceolate, short, arising above mid length, apex acute, obtuse, or rounded. |
2–19 × 1.5–5 cm; bracts proximally pale greenish to greenish gray, distally bright red to orange-red, sometimes pinkish, magenta, or salmon, rarely yellow, oblong to narrowly lanceolate or narrowly oblanceolate, deeply 0–3(–5)-lobed; lobes spreading, oblanceolate or linear, long, arising below mid length, distal bract apex usually rounded. |
Corollas | straight, 15–24(–26) mm; tube 12–16 mm; beak exserted, abaxial lip equal to calyx; beak adaxially green or ± yellow-green, 7–10 mm, puberulent, stipitate-glandular; abaxial lip deep green, reduced, rounded, 1–2 mm, 10–25% as long as beak; teeth incurved to erect, light green, 0.5–1 mm. |
curved in proximal 1/3, 23–35(–42) mm; tube 12–17 mm; beak exserted, adaxially greenish to yellowish, 11–22 mm; abaxial lip dark green, reduced, 1–4 mm, ca. 20% as long as beak; teeth incurved, reduced, green, 0.5–2.5 mm. |
Calyces | green or whitish with green veins, lobes colored as bract lobes or paler, 14–30 mm; abaxial and adaxial clefts 5.5–8.5 mm, 30–40% of calyx length, deeper than laterals, lateral 1.5–4 mm, 20–25% of calyx length; lobes oblong to narrowly triangular, apex obtuse to rounded. |
proximally whitish to green, central band whitish, distal 1/3 colored as bract lobes, sometimes lighter or deeper, 15–29 mm; abaxial and adaxial clefts 6–14 mm, ca. 50% of calyx length, deeper than laterals, lateral 0–5 mm, 0–5(–15)% of calyx length; lobes oblong to broadly triangular, apex rounded, truncate, or emarginate. |

Discussion | Castilleja brevilobata is endemic to dry serpentine openings in the Siskiyou Mountains of southwestern Oregon and adjacent California. Although sometimes treated as part of C. applegatei or C. hispida, its morphology does not suggest a close connection with either. This species occasionally hybridizes with C. pruinosa in Del Norte County, California. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Most records of Castilleja lanata are from the southern third of Arizona, New Mexico, and southwestern Texas. Plants sometimes referred to C. lanata from the Channel Islands of California are assigned here to C. hololeuca, an insular endemic. In northern Mexico, C. lanata extends from San Luis Potosí and Nuevo León westward to Sonora, with a disjunct distribution in central Baja California, where it overlaps the southern limits of a related species, C. foliolosa. Castilleja lanata inhabits a wide spectrum of soils and elevations and does not co-occur with the closely related C. galehintoniae in Nuevo León, where the latter is limited to limestone and gypsum substrates in a narrow elevational range. Hybrids of C. lanata with C. sessiliflora are known from Pecos County, Texas. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
