--><span class="statement" id="st-undefined" data-properties=""><b>Herbs,</b> perennial, 0.9–3.8(–4) dm; from a woody caudex; with a taproot. <b>Stems</b> 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. <b>Leaves</b> 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. <b>Inflorescences</b> 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. <b>Calyces</b> 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. <b>Corollas</b> 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.</span><!--

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