Herbs, annual, sometimes biennial, 0.6–3.5 dm; with fibrous roots. Stems few to many, sometimes solitary (var. meadii), ascending or erect, often decumbent proximally, unbranched or branched above base, hairs sparse to moderately dense, spreading, long, soft, eglandular, mixed with short stipitate-glandular hairs. Leaves green or brownish in upland forms, linear-lanceolate to widely lanceolate, linear, elliptic, obovate, or oblong, rarely ovate or cup-shaped, (0.6–)0.8–5 cm, fleshy or not, margins plane, flat, 3–5(–7)-lobed, apex rounded to obtuse or acuminate, abaxial surface often stipitate-glandular, adaxial sometimes shiny, glabrous; lobes ascending to erect, linear to lanceolate, apex acute or obtuse. Inflorescences 1.5–9(–13) × 1–4 cm; bracts proximally green, rarely brownish purple, distally white, cream, pink, or purple on apices, lanceolate, oblong, or ovate, (0–)3–5(–7)-lobed; lobes ascending or divaricate-ascending, oblong to linear, short to long, arising below or above mid length, central lobe apex usually rounded to truncate, others acute to obtuse. Calyces green to pale yellowish green or tipped with white or purple, 8–23 mm; abaxial and adaxial clefts 5–9 mm, 33–50(–67)% of calyx length, lateral 2–5.5 mm, 20–40% of calyx length; lobes linear or narrowly lanceolate to oblong or ± triangular, apex acuminate or narrowly acute to obtuse or rounded. Corollas straight, 14–24 mm; tube 11–21 mm, expanded distally; abaxial lip and beak usually exserted, beak straight or slightly curved, adaxially white, yellow, or pink, sometimes green or purplish, (1–)4–7 mm, sparsely to densely short-hairy; abaxial lip pale to bright yellow, sometimes becoming pink, orange, or red after anthesis, with red-brown or purple spots at base of each tooth and sometimes at base of each pouch, conspicuous, pouches 3, ± prominent, divergent, saccate, 2–7 × 3–7 mm, (33–)60–75(–90)% as long as beak; teeth erect, sometimes spreading, white, pink, purple, or green, often with whitish bases, 1–3 mm. Filaments glabrous. 2n = 24.
Distribution
w North America.
Discussion
