Habit | Herbs, perennial, 1–5 dm; from a branched, woody caudex; with a taproot. | Herbs or subshrubs, sometimes shrubs, perennial, 1.2–6 dm; from a woody caudex; with a taproot. |
Stems | solitary or few, erect or ascending, unbranched, sometimes branched, hairs spreading, short, medium, and long, soft, short and medium ones short stipitate-glandular. |
many, ascending, white or grayish due to hairs branched, much-branched proximally, unbranched to sometimes branched on distal 1/2, also usually with short axillary branches, base often shrubby and with marcescent leaves of previous year, hairs dense, appressed to spreading, medium length, soft, much-branched, eglandular, white-woolly, 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. |
whitish or grayish, linear to narrowly lanceolate or narrowly oblong, 0.9–5 cm, not fleshy, margins plane, involute, 0–3-lobed, apex obtuse to rounded; lobes divergent, spreading, linear, apex acuminate 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. |
2.5–20 × 1.5–3 cm; bracts proximally green to dull pale purplish, distally red, scarlet, rose, yellow, orange, or cream, sometimes pink or white, lanceolate to oblanceolate, (0–)3–5-lobed; lobes spreading, or distal ones erect, often oblanceolate, if 5-lobed, distal lobes usually very shallow, long or distal short, proximal bracts arising below mid length, distal ones arising near apex, apex rounded to truncate. |
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. |
straight or slightly curved, 16–27 mm; tube (8–)10–12(–14) mm; beak exserted or partially so, adaxially green, (7–)8.5–14 mm; abaxial lip deep green, reduced, 1–3 mm, 20–33% as long as beak; teeth incurved, reduced, green, 0.5 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 green, apices colored as bracts, 14–20(–22) mm; abaxial and adaxial clefts 3.5–7(–9) mm, 33–40% of calyx length, deeper than laterals, lateral 0(–1) mm, 0(–7)% of calyx length; lobes broadly triangular, apex of lobes and segments broadly rounded to truncate, segments, if present, obtuse. |

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.) |
Castilleja foliolosa inhabits chaparral from northern California southward to northern Baja California, west of the Sierra Nevada crest. The inflorescence is usually red or red-orange but can vary to white, yellow, pink, or purple. It is present on Santa Catalina Island in the southern Channel Islands, Los Angeles County, but is replaced in the northern Channel Islands by C. hololeuca, a related shrubby species. Castilleja foliolosa hybridizes with C. martini var. martini in San Diego County. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
