--><span class="statement" id="st-undefined" data-properties=""><b>Herbs,</b> annual or short-lived perennial, 0.6–3 dm; from a woody caudex; with a slender taproot. <b>Stems</b> solitary or few, erect to erect-ascending, sometimes slightly curved at base, branched at base or unbranched, hairs spreading, long, stiff to soft, mixed with shorter stipitate-glandular ones. <b>Leaves</b> brown or purplish, sometimes green, linear to narrowly oblong, 1–5 cm, not fleshy, margins wavy, mostly involute, to flat, 3–5-lobed, apex acute; lobes spreading, linear, apex acute to obtuse. <b>Inflorescences</b> 2–17 × 1.5–6.5 cm; bracts greenish throughout, narrowly lanceolate (ovate in outline), 3–5(–7)-lobed; lobes spreading, linear to narrowly oblong, long, arising from 1/3–2/3 blade length, wavy-margined, apex rounded or obtuse to acute. <b>Calyces</b> proximally brownish green, purplish, or green, lobes tipped with same color as bracts, 18–28 mm; abaxial and adaxial clefts 6–14 mm, 33–50% of calyx length, deeper than laterals, lateral 1.5–6 mm, 8–20% of calyx length; lobes lanceolate to narrowly triangular, abaxials wider than adaxials, apex acute. <b>Corollas</b> straight proximally, conspicuously decurved distally, 35–60 mm; tube 26–46 mm; abaxial lip, beak, and majority of tube exserted; beak yellow to yellowish green, sometimes purplish tipped or drying pinkish, 9–15 mm; abaxial lip light yellow to whitish, prominent, not inflated, 4–8 mm, 50–75% as long as beak; teeth spreading-ascending, yellowish, 3–6 mm. <b>2n</b> = 24.</span><!--

|discussion=<p><i>Castilleja mexicana</i> occurs in the northern third of Mexico and reaches the flora area only in southwestern Texas. Its conspicuous corollas can be either yellow or, less commonly, white. In both cases, the flowers turn soft pink-purple with age. Texas populations of this species are yellow flowered, and the white-flowered morph appears to occur only in northeastern Mexico. There is some indication of additional morphological differences between these color morphs that may justify varietal segregation. <i>Castilleja mexicana</i> is sometimes confused with the closely related <i>C. sessiliflora</i>, due to their conspicuous, distally curved, usually strongly exserted corollas, but the two species remain distinct.</p>
