Habit Herbs, perennial, 0.9–3.8(–4) dm; from a woody caudex; with a taproot. Herbs or subshrubs, sometimes shrubs, perennial, 1.2–6 dm; from a woody caudex; with a taproot.
Stems

few to many, ascending to erect, branched, especially near base, sometimes unbranched, hairs sparse to dense, spreading to retrorse, long, sometimes short, soft to stiff, usually mixed with short-glandular ones, sometimes viscid.

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

brown or purplish, sometimes green, linear to lanceolate or broadly lanceolate, 1.2–7(–7.5) cm, not fleshy, margins plane, sometimes ± wavy, involute or flat, (0–)3–5-lobed, rarely with secondary lobes, apex acuminate to rounded;

lobes spreading, oblong or lanceolate to linear-lanceolate, apex acute to rounded.

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

2.5–20 × 1.5–5 cm;

bracts proximally greenish or dull purplish, distally pink, magenta, pink-purple, reddish pink, pale yellow, pale yellow-orange, pale orange, or white, rarely reddish or orange-red, lanceolate to oblong, 3–5(–9)-lobed, sometimes with secondary lobes;

lobes spreading or ascending, oblanceolate or linear, proximal lobes often much longer than distal, proximal lobes arising below or a little above mid length, apex acute to 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, 18–27(–32) mm;

tube 8–17 mm;

beak usually long-exserted, adaxially green or pink, 8–15 mm;

abaxial lip deep green, reduced, inconspicuous, 1–2.5 mm, 5–20% as long as beak;

teeth incurved to ascending, deep green, 0.5–1.5 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

proximally green, yellow, brown, or purple, lobes colored as bract lobes, sometimes with a yellow band between proximal and distal parts, 13–25(–28) mm;

abaxial clefts 3–8 mm, adaxial 5–9(–12) mm, clefts 30–50% of calyx length, deeper than laterals, lateral (1–)1.5–4(–5) mm, 10–25% of calyx length;

lobes lanceolate to oblong, abaxials wider than adaxials, apex acute 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

Varieties 3 (3 in the flora).

Much confusion exists concerning Castilleja angustifolia and the closely related C. chromosa. Sometimes C. chromosa is treated as a variety of C. angustifolia, using the name C. angustifolia var. dubia. The latter name is used here to represent a different assemblage of plants, not including C. chromosa. At other times, C. chromosa is synonymized completely under C. angustifolia. However, the two species are in most cases easily separable, and where they are sympatric there is little evidence of intergradation. Both C. angustifolia var. dubia and C. chromosa are accepted here. See additional comments under 3b. C. angustifolia var. dubia and 15. C. chromosa.

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.
