Flora of North America species comparison

many, erect, unbranched or branched, sometimes with small, leafy axillary branches, hairs spreading, long, soft, mixed with shorter stipitate-glandular ones.

few to several, erect or ascending, unbranched, sometimes branched, hairs dense distally, less so proximally, spreading, long, soft, eglandular, also mixed with short stipitate-glandular ones distally.

green or purple-tinged, lanceolate to linear-oblong, 0.8–6.1 cm, not fleshy, margins wavy, involute, 0(–3)-lobed, apex rounded to acute;

lobes spreading-ascending, narrowly lanceolate, apex acute to acuminate.

green to purple, narrowly to broadly lanceolate to oblong, (0.7–)1.5–4.2(–5) cm, not fleshy, margins plane, flat or involute, (0–)3(–5)-lobed, apex acuminate;

lobes ascending-spreading, narrowly lanceolate to linear, apex acute.

3–34 × 1.5–3.5 cm;

flowers usually distichous, remote, except distalmost;

bracts proximally greenish, distally greenish, reddish, orange-red, or dull orange, rarely yellow, proximal bracts frequently greenish throughout, lanceolate to narrowly ovate or narrowly oblong-elliptic, 0(–3)-lobed, proximal wavy-margined;

lobes ascending, triangular, short, arising near apex, apex acute to obtuse.

2.5–7.5(–15) × 1.5–3 cm;

bracts proximally greenish to dull reddish, distally bright red, orange, or pale orange, sometimes yellowish or dull red, broadly lanceolate to oblong, 3–5-lobed;

lobes ascending, linear to lanceolate, ± long, arising above mid length, sometimes below mid length on proximal bracts, central lobe apex acute, rarely narrowly obtuse, lateral ones acute.

± curved, 25–38 mm;

tube 14–18 mm;

beak and often abaxial lip exserted;

beak adaxially dull orange or dull red, rarely yellow, 14–19 mm;

abaxial lip slightly curved, green, red, whitish, or yellow, not inflated, 2–2.5 mm, 15% as long as beak;

teeth erect or curved, yellow or green, 0.7–1 mm.

proximally whitish, green, or purple, distally colored as bracts, 9–18 mm;

abaxial clefts 6–6.5 mm, adaxial 7–9 mm, clefts 33+% of calyx length, deeper than laterals, lateral 1.5–4 mm, ca. 10% of calyx length;

lobes linear-lanceolate, apex acute.

proximally light green or yellow, distally yellow or colored as bracts, 12–20 mm;

abaxial and adaxial clefts 5–9 mm, 40–50% of calyx length, deeper than laterals, lateral (1.5–)3–5.8 mm, 10–30% of calyx length;
