Flora of North America species comparison

few to many, erect or ascending, sometimes decumbent, unbranched or often branched proximally, hairs spreading, medium length and long, soft, mixed with more abundant stipitate-glandular ones.

few to several, ascending to erect, unbranched, hairs moderately dense, often retrorse, short, ± stiff, stipitate-glandular distally only in inflorescence.

green, linear-lanceolate to sometimes narrowly oblong or narrowly oblanceolate, 0.7–3.7 cm, not fleshy, margins wavy, involute, 0(–5)-lobed, apex acute;

lateral lobes ascending to erect, narrowly lanceolate to narrowly oblong, usually narrower than center lobe, apex acute.

appressed-ascending, green to purplish, linear to narrowly lanceolate, distal sometimes broadly lanceolate, (1–)2.5–4(–5.5) cm, not fleshy, margins plane, involute, 0(–5)-lobed, apex rounded to acuminate;

lobes ascending, linear to narrowly lanceolate, apex acute.

2.5–10 × 2–5 cm;

bracts proximally pale green to pale yellow, distally yellow, whitish, pink, dull red, or purple on apices (sometimes gradually differentiated from proximal coloration), lanceolate, broadly lanceolate, or oblong, 3–5(–7)-lobed, sometimes with secondary lobes;

lobes ascending to spreading, linear, sometimes rounded, medium length or distal short, arising near mid length, apex acute to rarely obtuse.

2–7 × 1.5–2 cm;

bracts proximally pale green to pale yellow-green, distally pale to bright yellow or cream, rarely pale orange, elliptic, narrowly ovate, elliptic-oblong, broadly lanceolate, or ovate, (0–)3(–5)-lobed;

lobes ascending or spreading, narrowly lanceolate, short, arising near tip on distal bracts, central lobe apex rounded to truncate, lateral ones acute to rounded.

tube 15 mm;

abaxial lip usually hidden or just visible in abaxial calyx notch, not exserted/longer than calyx, beak exserted;

beak straight or slightly curved, adaxially green, 8–11(–12) mm;
