Habit | Herbs, perennial, 1.4–8 dm; from a woody caudex; with a taproot. | Herbs, annual, (0.6–)1–3(–4) dm; with fibrous roots. |
Stems | many, erect, unbranched or branched, sometimes with small, leafy axillary branches, hairs spreading, long, soft, mixed with shorter stipitate-glandular ones. |
solitary, erect, unbranched or branched, hairs spreading, medium length and long, soft to ± stiff, mixed with shorter stipitate-glandular ones. |
Leaves | green or purple-tinged, lanceolate to linear-oblong, 0.8–6.1 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, apex rounded to acute; lobes spreading-ascending, narrowly lanceolate, apex acute to acuminate. |
green to purple, linear to narrowly lanceolate, 0.5–4.2 cm, not fleshy, margins plane, flat, 0(–5)-lobed, apex acuminate to acute; lobes ascending to erect, linear to narrowly lanceolate, apex acuminate. |
Inflorescences | 3–34 × 1.5–3.5 cm; flowers usually distichous, remote, except distalmost; bracts proximally greenish, distally greenish, reddish, orange-red, or dull orange, rarely yellow, proximal bracts frequently greenish throughout, lanceolate to narrowly ovate or narrowly oblong-elliptic, 0(–3)-lobed, proximal wavy-margined; lobes ascending, triangular, short, arising near apex, apex acute to obtuse. |
1.5–15 × 1.5–3 cm; bracts green throughout, or proximally green, distally white to rarely cream on apices, with a tuft of erect, white, soft hairs, especially when immature, narrowly lanceolate to narrowly ovate, 3–5-lobed; lobes ascending, linear to lanceolate, long, proximal lobes arising near base, apex obtuse to acute. |
Corollas | ± curved, 25–38 mm; tube 14–18 mm; beak and often abaxial lip exserted; beak adaxially dull orange or dull red, rarely yellow, 14–19 mm; abaxial lip slightly curved, green, red, whitish, or yellow, not inflated, 2–2.5 mm, 15% as long as beak; teeth incurved, deep green to reddish, 1–1.5 mm. |
straight or slightly curved distally, 12–25 mm; tube 18 mm; abaxial lip and beak exserted; beak adaxially white or pale yellow, 3.5–9 mm, hairs dense, spreading, medium length, obscuring surface; abaxial lip yellow, inflated, abruptly expanded, obpyramidal, pouches 3, central pouch slightly 2-lobed, 4–5 mm deep, 3–8 mm, 75–90% as long as beak; teeth erect, whitish to pale yellow, 1–2 mm. |
Calyces | proximally whitish, green, or purple, distally colored as bracts, 9–18 mm; abaxial clefts 6–6.5 mm, adaxial 7–9 mm, clefts 33+% of calyx length, deeper than laterals, lateral 1.5–4 mm, ca. 10% of calyx length; lobes linear-lanceolate, apex acute. |
light green, lobes deep green, sometimes purple, 5.5–12 mm; abaxial and adaxial clefts 2.5–6.5 mm, 30–50% of calyx length, lateral 2–4.5 mm, 30–40% of calyx length; lobes linear to narrowly lanceolate or triangular, apex acuminate or acute. |

Discussion | Castilleja disticha is limited to the central and southern Sierra Nevada. Although similar to C. applegatei and C. martini, C. disticha is distinctive and unique in its long, colorful, and highly exserted corollas with the beak exceeding the tube in length, calyces more brightly colored than the often unlobed bracts, and tall, strongly distichous growth form.

Most populations of Castilleja lasiorhyncha are in the San Bernardino Mountains, with a few records in the adjacent Peninsular Ranges immediately to the south. The distal tufts of soft, pale hairs on the immature bracts are apparently unique in the genus. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
