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.

several to many, erect to sprawling, usually profusely branched, including many small, leafy axillary shoots, hairs dense, retrorse, medium length, stiff, eglandular, distally spreading, long, soft, sometimes matted, very short-glandular.

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.

green, linear-lanceolate, distally sometimes broadly lanceolate, 2–4.5 cm on main branch, 0.5–1 cm on proximal part of side branches, not fleshy, margins plane, involute, sometimes flat, 0-lobed, apex acute to acuminate.

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.

2–4.5(–14 in fruit) × 1.5–4 cm;

bracts proximally greenish, distally red to reddish orange, broadly lanceolate to oblong, 0(–3)-lobed;

lobes ascending, lanceolate, short, arising above mid length, apex acute to obtuse.

straight or slightly curved, (20–)22–30 mm;

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;

abaxial lip deep green to yellow, reduced, slightly pouched, 1–2.5 mm, to 20% as long as beak;

teeth incurved, white or green, 0.4–0.7 mm.

proximally green or pale, distally colored as bracts, 17–21(–23) mm;

abaxial and adaxial clefts 4–8 mm, 33–50% of calyx length, deeper than laterals, lateral 2–6 mm, 15–33% of calyx length;

lobes linear, narrowly lanceolate, or narrowly triangular to oblong, apex acute.

proximally pale green to pale yellow-green, distally pale red to red-orange above middle, 12.5–20.5 mm;

abaxial and adaxial clefts 6–9 mm, 33–50% of calyx length, deeper than laterals, lateral (1.5–)3–4 mm, 20–35% of calyx length;
