lemon paintbrush

Monterey coast paintbrush, Monterey Indian paintbrush, Monterey paintbrush, seaside paintbrush

Habit Herbs, perennial, 1.5–3.5 dm; from a slender, woody caudex; with a taproot or stout, branched roots. Herbs or subshrubs, perennial, 2–6 dm; from a woody caudex and sometimes from a woody proximal stem; with a taproot.
Stems

few to many, erect to ascending, unbranched or branched, hairs appressed to ± ascending, matted, long, soft, mixed with short-glandular ones, denser distally, sometimes obscuring surface.

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.

Leaves

green, sometimes brown, linear to linear-lanceolate, 3–7 cm, not fleshy, margins plane, involute, 3–7-lobed, apex acute to rounded;

lateral lobes spreading, narrowly linear, apex acuminate.

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.

Inflorescences

(3.5–)8–20 × 2–5.5 cm;

bracts proximally greenish, distally bright yellow, sometimes pale yellow to pale orange, sometimes aging white to pink, narrowly to broadly lanceolate or oblong, 3–5(–7)-lobed;

lobes spreading to ascending, linear, long, arising at or below mid length, apex obtuse to rounded.

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.

Corollas

straight but curved at tip, 30–41 mm;

tube 21–26 mm;

beak slightly to long-exserted, adaxially green to yellowish, sometimes aging pinkish, 10–15 mm;

abaxial lip white or yellow, sometimes partly green, darkening with age, only slightly inflated, exserted from abaxial cleft, 3–7 mm, ca. 50% as long as beak;

teeth prominent, petaloid, spreading, yellow, 2.5–6 mm.

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.

Calyces

green, pale green, or whitish, lobes colored as bracts, 12–18 mm;

abaxial and adaxial clefts 8–15 mm, 60–75% of calyx length, deeper than laterals, lateral 2.5–3 mm, 20% of calyx length;

lobes linear to very narrowly triangular (equilaterally triangular if very short), apex obtuse to rounded.

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.

Discussion

Although the range of Castilleja citrina overlaps the range of its close relatives, C. lindheimeri and C. purpurea, in central Texas, C. citrina extends considerably farther to the west and northwest of the others (G. L. Nesom and J. M. Egger 2014). The inflorescences of C. citrina are mostly pale to bright lemon yellow or occasionally brassy yellow. The color and usually more elongate abaxial corolla lip separate it from C. lindheimeri and C. purpurea. Castilleja citrina is similar to some color forms of C. sessiliflora, but the more conspicuously curved corolla of C. sessiliflora is usually exserted far above the calyx and is often white to pale pink, rather than yellow.

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.
