Habit | Herbs, perennial, 0.4–1.7 dm; from a woody caudex; with a taproot. | Herbs, annual, (0.6–)1–3(–4) dm; with fibrous roots. |
Stems | few to several, ascending to decumbent-based, unbranched, hairs spreading, long, soft to stiff, 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 to deep purple, linear to narrowly lanceolate, (0.5–)1–2.5(–3.1) cm, not fleshy, margins plane, flat to slightly involute, 3(–7)-lobed, apex acuminate; lobes ascending-erect, linear to filiform, apex acute to obtuse. |
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 | 15–20 × 1.5–3 cm; bracts greenish or deep purplish throughout, or proximally greenish or deep purplish, distally white, pink, magenta, reddish purple, purple, or pale yellow, distal coloration often limited to apices and margins, broadly lanceolate or narrowly to broadly elliptic, 0–3(–7)-lobed; lobes spreading, linear to narrowly oblanceolate, long, arising near mid length, apex acute or 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 | straight, 10–16(–19) mm; tube 8–13 mm, with patches of blackish coloration on either side of distal portion; beak subequal to calyx or exserted, adaxially green, yellow, whitish, or pink, 3–5.5 mm, scarcely exceeding abaxial lip, margins brown or burgundy, sometimes pink; abaxial lip pale yellow, white, green, or purple, inflated, pouched, 2–5 mm, 65–95% as long as beak; teeth erect to slightly spreading, white, yellow, or pink, 0.5–2.1 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 | green to purple, margins green, white, or pink, 10–19 mm; abaxial, adaxial, and lateral clefts 3.5–7(–10) mm, 33–55% of calyx length, all 4 clefts subequal; lobes linear, lanceolate-elliptic, or narrowly triangular, apex acute to rounded. |
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 nana is limited to high elevations in the Sierra Nevada of California and the Great Basin ranges in central Nevada and western Utah. Plants with pink to purple inflorescences were described as C. lapidicola. Localized hybrid swarms between C. nana and C. viscidula are known from several mountain ranges in central and northern Nevada. Castilleja nana is sometimes confused with higher elevation forms of C. pilosa but can usually be distinguished from that species by the blackish patches on the sides of the corolla tube. Divergent populations in the central Sierra Nevada and adjacent White Mountains deserve further study. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
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.) |
